All language subtitles for Girls High School Mystery Class S03E05

(All characters, places, incidents
and organizations are fictional)

(Any resemblance to actual persons
or events is purely coincidental)

(The secret area in the counseling
room is filled with information)

- What's the matter?
- There's blood on the ceiling.

What is this?

What floor is above this room?

(Counseling room)

It's the laboratory.

I don't want to go up.

I hated going up since
it is a laboratory.

The scariest place in school
is the laboratory.

There are many scary things
in there.

I told myself we wouldn't be going
to the lab after transferring

to this school.

The lab is always the scariest.

(Sad)

(She does not want to accept
the reality)

We need to go to the lab?

Let's go.

(Oh no)

What is this? Is this from Mina?

Is Mina already dead?

The lights are on.

The lights at the lab
are always turned off.

(The lab that is always dark)

However, it is bright today.

I'm certain that something
is happening right now.

- Please.
- She might be working now.

(Entering cautiously)

I think it is over there.

There's blood.

There's blood over there.

Oh no!

Blood...

We went to the lab

and found blood stains.

There was a pool of blood.

(There is a pool of blood
in front of the door)

- What was that?
- We are locked in?

We are.

Someone locked the door
as soon as we entered.

It must be a criminal who is
trying to flee the scene.

(Are we actually locked in?)

Open the door.

Oh? The door is locked.

(Are the windows locked too?)

(As expected, yes)

We can't open this?

(They are locked in the lab)

(Peeking)

(This still looks scary)

(What happened here?)

Can it open?

It does.

(The door is locked)

- Why?
- I hate this.

(All of them panic)

The door is locked.

(Looking closely)

Hold on. This...

I think something happened here.

What is it?

This person was either
banged against the window

or there was a bloody battle here.

There's someone over there!

- Where?
- Between the trees.

- Who is that?
- Hey!

We opened the window
and looked outside.

A female student who is
wearing a black hoodie

was running away.

It feels like

she locked us in the lab
and ran away from school.

Who is that person in
the black hoodie?

Is that actually Guk Jihee?

Or is that the main villain?

I think we should run after her.

But we are locked in right now.

- Someone is locked in here.
- I think it's Mina.

I think Mina is inside. Oh no!

We need to find the key
to save Mina.

Let's find the keys right now.

(Where is the key?)

She should not die.

Where did she leave the key?

(Frozen)

(Oh?)

- The ringtone!
- Mina's ringtone!

Mina!

Are you okay, Mina?

- Mina!
- Mina!

The reason I was certain that
Mina is inside,

is because the ringtone we
heard from the locker

and the music we heard
at her home

were the same as the one
we heard in the lab.

Mina is here.

(They desperately call her name)

(But nobody responds)

- Mina.
- You haven't found the key?

I doubt she would leave
the key here.

She might have since she
was rushing to leave.

(I want to find the key
but I am scared too)

(Where is the key?)

Jiyoon, turn this on.

Jiyoon, turn this on.

We might find something else here.

(They find a way to save
Mina using Munbanggu)

If we open Munbanggu again,

will we be able to find
hints to the key?

We believe that the lab
will look the same here.

The moment we turn on
the laptop...

(In a rush)

(Someone is approaching
the laboratory)

It's Mr. Suyeol.

It's Mr. Suyeol.

I feel even more scared now.

What are you doing here?

(Oh?)

We were locked inside.

You were locked in?
What do you mean by that?

(They told him what happened)

Calm down. Why are you still
here and not home yet?

That is not important.
There is blood...

- What?
- There is blood over there.

- Blood?
- Yes.

I will investigate that.

- So you should go down now.
- No.

You should go down for now.

You should not walk in school
until late at night.

Go down now.

This might be dangerous.
So go home right now.

How can we leave since
we saw blood?

I will decide to make a report
or check what happened.

Just go down. Do you understand?

Go now.

If he was not aware of anything

and came to the lab, he would
not have chased us away.

Isn't it more normal to ask
someone to make a report?

'Go home right now. Just go home'.

That made me very suspicious.

He is weird.

I think Cha Suyeol is related
to this case.

It's weird that he is
still here at this hour.

(How is Cha Suyeol related
to what happened today?)

(High School Mystery Club 3)

(It is now in the middle
of winter)

(The third day in school for
the mystery club)

(What will happen
in Songhwa today?)

(Careful)

Hello.

It is snowing.

Our road to school
is very romantic.

I am so excited.

How does it feel to go
to school on a snowy day?

It has been a long...

This happens all the time
but I am still excited.

(Jiyoon is the first
to arrive today)

My precious laptop that belongs
to Mina.

I stole it but I feel relieved.

Hello.

I feel so comfortable since
I'm wearing pants today.

It is very warm here too.

The weather is just...

I think it's snowing too heavily.

Hello.

You're so pretty.

(A warm welcome by
the pretty Jiyoon)

I wore gloves so that
we can play in the snow.

Yes!

(They are ready to become
children again)

Shall we build a snowman?

- I'd love that.
- I think that will be fun.

I want to make a snowman.

(Another person is in the mood
for 'Frozen' too)

I can't believe that I am
in the snow dynasty.

Shall we go to Songhwa that flows
with the energy of Samgyocheon?

(Sometimes she malfunctions)

Hi.

Isn't it great that it is snowing?

I love it.

(Found something)

Jiyoon.

You look like a parent today.

- What?
- You look like a parent.

(Jiyoon looks like
an adult today)

I don't have clothes.

I ended up wearing
my mother's jacket

and now look like a mother!

I hate my mom!

My mom said since today
is a holiday,

she rolled my hair tightly.

Why is my hair like this?

(BIBI arrives amidst the chaos)

(She arrives in all-white fashion)

BIBI, you dressed up
prettily today.

I am regretting my decision
to dress up today.

You look so tense now.

(Jaejae and BIBI are wearing
the same shoes)

(Including Jiyoon)

Don't join us.

(BIBI doesn't give in just
because someone looks cute)

But you know this, right?

Doyoun had to let go of her
padded jacket because of us.

(We will give you a new jacket,
so give us the old necklace)

Oh no.

She said her mother
was very angry.

There are rumors that Doyoun
burnt all of her clothes.

- Oh no.
- She cut her hair too.

Is she going to be naked today?

Oh no. Poor Doyoun.

(That is when Doyoun appears)

Doyoun.

Looks like the rumors are true.

It's true that you burned all your
clothes as you lost your Moncler?

Yes.

(Doyoun only has her uniform)

There were also rumors that
you shaved your head.

This is not a wig, is it?

Don't touch it!

Sir, don't brake suddenly.
This might fly away.

Oh no.

(New item: Moncler padded jacket.
Drop by to inquire about it)

There's a lot of snow here.

(This whole town is covered
in snow)

Into the unknown!

(Let's sing together)

(The school bus is our stage)

(Chorus)

I think we can shoo spirits away
like this.

We would defeat them.

(They try to sound like Elsa)

We will get rid of all of them.

Do you remember what happened
in school yesterday?

The laboratory.

Yes. Our lab.

(Scary memory from yesterday)

The person who was locked up...

(The one locked up...)

(Is it Mina?)

Mr. Suyeol told us to leave
in a scary manner.

Yes.

Something is wrong with him.

I think he is the devil.

Why did he tell us to leave?

I know, right?

I think we won't be able to find
anything at the lab now.

- I bet it is clean now.
- As if nothing happened?

But we saw it.

But if Cha Suyeol
is one of the people

who was involved
in the incident,

would he go back to the scene
as if nothing happened?

Was he being used too?

Whose side is he on?

(They can't tell who
Mr. Suyeol is)

Based on the diary we saw,
our first day of school

was the day Mina was working
part-time.

Mina started working from 7PM.

I think Mina is always in pain
every time she works.

Mina was working at 7PM.

Looks like she is covered in
blood when she works.

I think the blood we saw yesterday
is related to that.

(Is the pool of blood in the lab
related to her part-time job?)

Actually, a lab can also turn into

an operation theater.

The lab?

(Grimacing)

(What happened in the lab?)

Is it a human experiment?

It's weird that it happened
in the lab.

(They are certain that it is
no ordinary part-time job)

- I think it's a human experiment.
- I think it's a human experiment.

It's a human experiment!

(Screaming)

This sounds fun.

(Doyoun's sanity gets burnt
with her clothes)

You're having a tough time?

(Nodding)

But listen.

We had a suicide case in school.

There is also a weird
gambling site in school too

that is connected to
a weird part-time job.

The victim
of this situation is Mina.

Does it mean that this actually
happened in the past too?

Do they send people who can't
pay there? It's a route?

Doesn't it feel that way?

The students who passed away
were all model students.

What caused them to suffer?

I don't think it is related
to studying.

Did they have financial issues
as well?

(What is the main cause of the
case from 20 years ago repeating?)

What is wrong with this school?

This is today's mission card.

(Time to get today's mission card)

'Notice of the day.

Today is November 21 and is
a discretionary school holiday.'

The time has come.

Why? What is it?

'Investigate Bi-Bi
parallel universe theory'.

Doyoun, you remember that

this involves you too, right?

(The curse has yet to end)

(They have another mission today)

(They have a meeting with
Youdon'tknowme)

We tried to persuade her using
Mina's brother but failed.

She said she'd tell us tomorrow.

That brat.

I think she is Shinhee as she is
worried about her extra class.

She does attend many academies.

Shinhee has the habit of

saying she has an extra class
when she has to leave.

But people who do that
actually don't go to class.

(They chattered away and
arrive at school)

There won't be teachers
in school today.

So let's search the school.

They will get it today.

Let's take a picture.

Okay, Jiyoon.

(Coming close together)

(WeWillConquerSchool
MysteryClub)

- Let's go.
- Let's go.

Let's go.

- Our school is pretty in snow.
- I agree.

(Our school has turned white
within one night)

(The green pines and campus
that they walk in daily)

(have turned white)

Do you remember the first time
it snowed?

Yes.

- That's the day Inhye died.
- Yes, that's right.

(It seems like the snow will
cover all blood stains)

(Songhwa feels creepy.
What awaits them?)

Do you think there will be
teachers here today?

I'm sure they have duties too.

Key!

I think Key will be here.

(Key a.k.a Jongdae is here
as a public service worker)

But he has to be absent

for us to steal the key
to the record library, right?

(They only think of stealing)

Doyoun, you can distract him.

Okay. I will try to be someone
who distracts him.

Be careful. It's slippery.

Okay.

I'm cold.

Hello, Mr. Sanmun.

Why are you here?
Today is a holiday.

Are you here to study?

We would like to self-study
at our clubroom.

Are you preparing for grade 12?

- Yes.
- It is all for our school.

Doyoun, you are committed
to studying.

Today is a holiday but
you are in your uniform.

Perfect. Follow me for a moment.

Are you the only one
in school today?

(Even Key is away today)

Mr. Suyeol is on night-duty.
So he will come soon.

Mr. Suyeol will be coming
as he is on night duty.

I have a bad feeling.

Did you go to Mina's place?

Yes, we did.

We met and spoke with her mother.

However, she has no idea
where Mina is at either.

We didn't get to meet her.

- You didn't?
- No.

Where is she?

Come here.

I'm glad you're here.

Do you know how to make
photocopies?

(Why are they doing
photocopies suddenly?)

This is our newsletter.

Please make 80 copies.

Please make 80 copies.

(80 copies?)

Please sort these according to
class and put them on that table.

- I see.
- Sorry?

Please help me, okay?

I have so much work to do.
I'm glad you're here. Thank you.

Since we're doing this, can we
eat snacks you have here?

We don't have any snacks.

(Confidently asking for snacks
meant for teachers)

Can we drink instant coffee?

(Instant coffee?)

We ran out of coffee

but you can have tea.

Have some tea.

(They have to work for tea)

We have to place the paper
facing upwards.

I haven't done this in ages.

(Someone suddenly enters
the teachers' office)

Then, we have to press
the 'copy' button.

Ms. Yujeong. You're not on duty
but you're here today.

I have some work to do.

(Emergency)

It's Ms. Kim Yujeong.

Ms. Yujeong, can you get hold
of Mr. Suyeol?

He's on duty with me but
I can't get hold of him.

You should wait a bit longer.

Is he sick?

It's weird he isn't here.

(Eyes on her)

Hello.

(Cold)

She didn't even greet us back.

(Ms. Kim Yujeong is cold)

(They are bothered)

Ms. Yujeong.

She doesn't look like
a nice person.

She looks very strict.

(Talking bad in front of
the teacher)

(Rummaging)

You're good.

You look like an office worker.

(What is that?)

(All eyes on her for a moment)

(Quietly moving beside her)

80 copies...

It takes a long time to make
80 copies.

(Peeking)

(Very curious)

Ms. Yujeong was looking
at something intently.

I took a peek and there
was a picture.

I couldn't see the name though.

(Getting closer)

(Stop right away)

What are you doing?

(Coming up with weird excuses)

I couldn't go close as
I'm a coward.

They continue to look at it
and even went closer.

(Friends she is proud of
for going closer confidently)

I saw Yoon Semi.

Lee Seulbi too.

You saw Seulbi's name too?

(Why are their names in
Ms. Yujeong's document?)

I was shocked.

Why does she have Seulbi's
student record?

Yoon Semi and Lee Seulbi.

This proves that something
ties both of them together.

We will be able to find important
clues in the teachers' office.

This is not working at all.

(Being mindful)

When will we make 80 copies?

(Shall we read the newsletter?)

(Notice on prevention of
theft and burglary)

If you have expensive items like
necklace, ring and laptop...

If you have expensive items like
necklaces, rings and laptops...

(Touching)

Wait. Hold on. We stole
the laptop.

(The thieves feel guilty)

I think we will be handing
these to everyone tomorrow.

(We can stop stealing from
tomorrow onwards)

(She doesn't care about
what they do)

We made 20 copies but
I only have 12 copies with me.

There are 8 copies here.

(Really?)

Jiyoon, this is a machine.

Jiyoon does not trust machines.

(Jiyoon is full of suspicions)

(The is the icon of being
meticulous / Distrust)

This is for Class 2-1.
Count if it's enough.

Okay.

(She believes neither
people nor machine)

(Working hard)

- Amazing.
- I am the vice president.

Do you have 20?

There's 17.

(Jiyoon is the president)

(At last, they only need
another 5 copies)

We are finally done.

At last, we are done.

I think we have stacks of
20 copies now.

(They are done with
the photocopy machine)

(Neat)

(They are done dividing and
arranging the stack of papers)

(The notices have been arranged
by crazy, no President, Jiyoon)

We are done.

You can go study then.

Thank you.

Thank you.

(They leave the result that
they are proud of behind)

(Moving discreetly)

(One pack of snacks)

I was wondering what bag
you were taking, Jiyoon.

(This is how thieves are)

(They stop in front of
the notice board)

Our final exams are coming soon.

Blooming Camp.

Blooming Camp?

(The camp which Mina
would like to attend)

(The clue inside Mina's locker)

Songhwa Blooming Camp?

(Application form
to Blooming Camp)

(Something is suspicious)

(They are very polite)

Blooming Camp.

(The snowflakes
are getting bigger)

(A snow landscape that
leaves them in awe)

It is snowing.

This is so nice.

Why is it dark here?

(The corridor is dark
as today is a holiday)

(They turn on the lights)

Let's bring this on.

Let's check in case.

(She just brings it in)

(As expected from BIBI)

- I think something...
- I love this!

Nice.

We are home.

(Their hearts feel at home)

(They check their mystery box
right away)

(Let's see)

Look at this.

We found this in Mina's locker.

Application form to Blooming Camp.

Blooming Camp is held
for 5 days.

(The Young Beauty
social contribution program)

(The Young Beauty is beauty and
health camp for selected students)

Beauty and health.
Human experiment!

Since she said that
she wanted to go

it means she might change how
she looks? Like get prettier?

Like in 'Let Me In'?

(Why does Mina have the form
to go to this camp?)

(They have collected many clues)

Let's enter Munbanggu again

and organize the cases that
took place there too.

- Okay.
- Got it.

(They open Mina's laptop)

How do we turn on
the hotspot again?

(While the human connector
connects it)

We don't have
a snack box, do we?

(We are hungry.
Where is our snack box?)

(Rummaging)

Doyoun.

(Touched)

My mom made me gimbap since
I said I'm going to study.

Is this a witch gimbap?

Is your mother a witch?

She is a witch?

(She cannot let them starve)

(She takes a big bite)

(Tasty)

Does it work?

(It is now connected to Wi-Fi)

(Enter the password)

(They are now in Munbanggu)

This is cute. They did a good job
at creating this.

The one who made this
will get a good job.

Let's go.

The admin is here.

(They found Ubangi's admin)

- Who is it?
- What?

Who are you?

The admin just sent this
to Mina, right?

Before this, there were only
conversations between Mina

and Youdontknowme or Guccilover.

But then, we found her
conversation with the admin.

That was when we saw
her financial statement.

What is this? 'Notice of
cooking repayment date'.

'Notice on overdue interest'.

The principal value is $10,000.

- The daily interest is $1,500?
- They take that much?

(Shocking financial statement)

She told me to come to the lab at
7 and a bad thing happened there.

This is what happened yesterday.

(They saw a pool of blood and
heard Mina's ringtone in the lab)

Mina must have gone there
after receiving this message.

It happened at 7PM too.

The admin is the culprit.

But who is the admin?

(They need to find out
who the admin is)

Let's read from the first message.

'Notice on payment date'.

(The first notice was sent
on November 6)

I will pay soon.

'Why do you sound so rigid?

You sound different.'

I guess they were close.

'Something happened during
my second-hand item transaction.

I will definitely pay you back
by tomorrow.

Please do not tell my mom.'

(Due to
second-hand transaction fraud)

(Mina was summoned
by the police in October)

'I will do my best to get your
money. Please let it slide once.

This is very tough on me now.'

'If you do not pay by 7PM
today,

I will proceed
as per the contract.'

What is in the contract?

Didn't we take a picture of
Mina's promissory note?

(There are promissory notes in
the secret room)

'If there is more than 3 days
delay, parents will be notified.'

Guardians will be notified?

She's scared that her mom
will find out about it.

'I agree that my participation in
games in Munbanggu is restricted'.

What is 'looking for part-timers'
about?

'I can do it. I can start
right away.'

Then, she was selected.

She was told to come to school
by 7

to which she agreed.
She went on Saturday.

(She was chosen on November 10
and she started work on 11)

November 13 is the day
we got transferred here.

'You are Gucci, aren't you?

I asked you in class too.

Can I do the part-time job
I did before too?'

Yes. We heard that on
our first day here.

(The first day in school)

Can I do that part-time job
again?

- What job?
- The one you introduced.

Part-time? Why would I
introduce a job to you?

(Is Jihee the admin for
Munbanggu?)

But it might not be her.

She didn't know what job
it was.

But she asked why does this
person sound unfamiliar.

Mina thinks the admin is Jihee

but it might be someone else.

Yes. the one who said that
she knows who the admin is

is Youdontknowme.

We decided to meet her
at 4PM today.

'Today at 7PM at the school...'

That was when we saw Mina's
ID that was stained with blood.

(The night of their first day
in school)

There is something there.

- It's a student ID.
- Hwang Mina.

(Mina's student ID is stained
with blood)

(November 13. First day in
school and Mina's part-time job)

'Can I do it again?'

She asks if she can do the
part-time job again.

'When can I work again?'

'I think I am in trouble because
of the archery team's case'.

She lost money from betting.

Is it because Hong Ai won?

Many students lost lots of
money because of that.

Mina must've felt so scared.

(Mina lost a lot of money due
to the archery team terror case)

We saw that she was asking for
a part-time job several times.

Is the reason they use

one's weakness to threaten
them

so that they can get people
to do part-time jobs?

(Final message from admin:
Come to lab at 7PM today)

(She was asked to go to the lab
on November 19)

Anyway, she searched for
a part-time job to get money.

It's true that she was in pain
and bleeding on those days.

So the first time we saw her
on November 13,

she was bleeding and walking
towards the abandoned building.

The next Monday,
she was bleeding

and we heard her phone's
ringtone in the lab.

(They saw a pool of blood
and heard Mina's phone's ringtone)

I think we have to solve this
as soon as possible.

What is today's mission?

Unravel the Bi-Bi
parallel universe theory.

Jaejae, go to the metaverse
and check on the notices.

Things happened there, right?

Can you please read them out
for me?

Okay?

(She checks the notice board)

March 2, 2022. Munbanggu
was established.

Gym was opened in May.

So was the counselling room.

Archery team tryouts forecast
game started in June.

Were there any days when
the site was checked?

What kind of check?
What do you need?

'Notice of
Munbanggu system check.'

October 1.

The site was opened again on
October 8.

The site was checked for a week.

(The site was closed from October
1st to 7th, after it was opened)

- New space opening notice.
- Record room.

(Record room is opening today)

It means there were not many
events for the past year.

(Munbanggu was peaceful
for the past year)

Let's go to the gym

and check on the dates
of the tryouts

as well as search for part-timers.
Tell me the dates for those.

'Notice on delayed result
announcement for tryouts)

(On November 13, the result was
delayed due to the terror case)

(The people involved are
Guccilover and Tak Sara?)

Special action was taken on
the 13th.

Coincidentally, Mina had to do
her part-time job that day too.

However, we don't know where
she went at 7PM.

It was not mentioned. She was
just told to go to school.

She was bleeding on those days.

We found blood stains on that day.

Are you sure it was recorded
as a part-time job?

It was just 'go to the lab
at 7PM'.

(Mina received a text although
she didn't ask for a job)

(November 11: You're chosen for
the job. Come to school at 7)

(November 13. Part-time job.
Come to school at 7 today)

(November 20: Unknown.
Come to the lab at 7 today)

She did not have
any part-time job that way?

(Hwang Mina part-time job?)

(They read
the chat messages again)

Wait. She paid everything.
The total is $7,000.

She paid $7,000 all at once?

She pays a debt of $7,000
with one part-time job?

The pay for the job is $7,000?

($5,000 was 4 days overdue so
it became $7,000)

(She cleared her debt of $7,000
with one part-time job)

What do you have to do
to get $7,000?

Yes. That's why it's dangerous.

This means she transferred
$7,000, right?

Or is it a drug trial?

She got some drug tested
on her?

Since this is a beauty camp,

it might be related to fat
or skin.

Is the drug created during
the camp tested on part-timers?

Or it's a drug that does
not make sense.

As an example, they test
eternal life or anti-aging drugs.

That's possible.

We have organized everything
we have so far.

To understand all these better,

I think we need to understand
the metaverse better.

Let's organize the things
we have to do today.

This is the bigger issue.

Unravel the parallel theory.

We need to know the relation
between metaverse and this theory.

Somehow...

The record room will
be opening today, right?

We can find old school documents
in that room.

If we bring this metaverse with
us to the room,

I think we'll find clues related
to the parallel universe theory.

(They will get new clues!)

To do that, we need to know
who the admin is.

So it's important for us
to meet Youdontknowme.

What must we say when
we meet her?

'Why are you here
instead of Mina?'

Why don't we say that
we are also

gambling on metaverse as
introduced by Mina?

And I have to do
a part-time job soon.

Youdontknowme might not know
about the job.

Or shall we just test the waters?

No. I think almost everybody
is playing this game.

However, there are no records of
others doing a part-time job.

Only those who have to do it
are aware of it.

- Only they know about it.
- They don't share information.

We should not reveal
what we know yet.

We don't know what she
will tell the others.

We can just say that Mina
wanted us to find out who he is.

If that doesn't work...

Yes, let's try to lure her
to give us information.

If necessary,

we can use Mina's brother.

We can use Mina's brother.

(Use whose brother?)

(Cute)

Is he single?

Mina's brother? He is single.

How do you know that?

- You asked him out?
- No, I did not.

Don't tell me...

What are you doing?

(Nothing is more fun
than teasing Mina)

It will be bad
if things go that way.

(Dangerous world)

(She almost lost her mind)

Let's get the key to open it.

Okay. Let's do that.

(They open the case box)

(There is something inside)

- What is that?
- Something is torn in here.

'Please put everything
back in its place)

There must be a reason
when someone places something

inside the mystery case box.

'Please put everything back
in its place'.

Isn't this from some poster?

Notice board? Teachers' office?

A place people hang posters.
Maybe the corridor?

Or classroom?

(Classroom?)

(Counseling room?)

(Teachers' office)

What places need to be organized?

Lab or library.

A place where we have
to use something there.

Shall we go to the lab?

(She is already scared)

(Time to look inside the dark room
as they failed to do so yesterday)

She might still be locked there.

Let's go.

(To find traces from yesterday)

(They start to move quickly)

I don't want to go there.

(The lab was stained with blood
last night)

(Did someone lock the lab again?)

The door is open.

(Taking a deep breath)

Hold your breath!

(The lab is so quiet)

(as if nothing happened
last night)

It's morning but why do I
still feel scared?

(Oh?)

'Rules to use the laboratory'.

'Rules to use the laboratory'.

- That is where it is from.
- Right there.

Yes. I knew it was something
like this.

(The paper found in their box
fits this paper perfectly)

Who would tear this and put
it inside our mystery case box?

I think it's a sign for us
to come to the lab.

(Who is it?)

(Why?)

(Why must we come to the lab?)

The blood has been wiped
and everything is clean.

- Really?
- Yes.

(All traces from yesterday
are missing)

It's like someone was clearing
the evidence. There's no blood.

Everything has been arranged
back in its place.

As expected,
all evidence has disappeared.

- Really?
- What? When?

The dark room is not locked.

- Shall we go in?
- Okay.

- It is unlocked?
- Yes.

(Screaming)

(They can see the dark interior
when the put the curtain aside)

(All tools have been
arranged neatly)

(Dark room)

This looks like a trap.

I'm scared.

I will watch out for anyone.

(They are reminded of
their PTSD of being locked in)

(Peeking)

(While BIBI stays on alert, they
start rummaging through the place)

Blood was dropping downstairs
from here.

(Did blood drop through the
ceiling from the pool of blood?)

I think there's a gap here.

It dripped from the tiles?

(Looks like it seeped
between the tiles)

(What happened here?)

But you know, right here,

there was blood.

We saw traces that
someone was dragged here.

There was blood on the window.

I think she was dragged in
from the window.

This is where it began.

She might have been hit here
and was dragged into the room.

Right.

- Try to think about it.
- Why?

Perhaps it wasn't Mina
who was murdered.

She might have brought someone
to the lab

and made that person stand here.

(Hitting)

(Dragging)

That might be the reason
Mina was in this room too.

So the part-time job might mean
she has to hurt others

instead of her hurting herself?

(Mina might be the assailant
and not the victim)

It means someone does not want
to get his or her hands dirty.

It might be Mina who we saw.

The reason it might be Mina
is because

we searched Mina's seat.

There was a black hoodie
on her chair that day.

(The culprit was wearing
a black hoodie last night)

When she heard us coming,

she shut the door and hid.

Then she ran away.

That person was Hwang Mina?

(Mina was the one
in the black hoodie?)

Did she leave her phone here?

She might have left
evidence behind.

Doesn't it mean that
the teacher who came here

might have found the evidence?

Mr. Cha Suyeol.

Which is the truth?

I don't know.

(Is Mina the victim or assailant?)

What was Mr. Suyeol doing here?

Cleaning up the place.

Why were we asked to come here?

Why did that person want us
to come here?

Why was this placed in
our mystery case box?

Rules to use the dark room.

'Cover the room with
the curtains well

to prevent any sunlight
from entering'.

'Please wear protection when you
are using chemicals in the room.'

Luminol reaction?

Let's try this.

There is equipment we can use too.

We will be able to find
blood stains.

(Luminol? Blood stain?)

This is that!

This is used at criminal sites.

Luminol reaction.

A luminol reaction is a test
to detect blood.

Yes, I did that before.

One of my favorite programs is

'Until the Day We Find the End'.

This situation appears often
in that show.

The bottle is labeled 'luminol'.

We see this kind of scene
in dramas.

They would do this

and spray everywhere.

Then they will find
the blood stains.

If we use luminol
in the dark room,

we think that we will be able to
find blood stains or clues.

That is when we quickly
put on our gloves and goggles.

We need to make sure
the surroundings are dark.

We need to stand as far as
possible from the spray.

Everybody, let's
enter the dark room.

We can see the reaction within
2 to 3 seconds.

Okay. Everybody.

I'll close the door.

Let's spray it for now.

(They have prepared the dark room)

Around this area.

(They start by spraying
the door)

I can see something glowing here.

This one is glowing.

(Any fluorescent reaction means
there is blood)

(The area close to the door
is shining)

Here.

I can see it.

I think these are stains
from yesterday.

There's a lot here.

Something must have happened here.

If we look from a distance,
we can see it is covered in blood.

This whole area is covered
in blood too.

There's a lot of blood here.

There's so much blood that I think

that person must have died.

Girls.

There's blood here too?

(They found blood everywhere.
Not just on the floor)

We wanted to just check
the walls.

We won't find any, right?

(Oh?)

- Girls.
- Where?

- Girls!
- What is the matter?

We saw it clearly when
we sprayed the wall.

How far does it go?

'Lee Seulbi'!

Lee Seulbi.

- 'Lee Seulbi'.
- It says 'Lee Seulbi'.

(One of the characters in the
Bi-Bi parallel universe theory)

(They keep on seeing these
names as they dig into this case)

Why is a dead person's name here?

Why is Lee Seulbi's name
written on the wall?

She passed away last year.

Or is she still alive?

What does this mean? 'Lee Seulbi'?

We almost finished up
the luminol.

We sprayed everywhere.

I saw this on 'C.S.I.' and have
always wanted to try it.

I feel so amazing now.

(The best of the best)

(She feels proud of herself)

First off...

(They return all items
back to where they belong)

The information we found
in the lab

says that the drops here are
related to Lee Seulbi.

But she died last year.

Did she not die?

When someone's name is written
at the crime scene,

there's high probability that it
is the culprit's name.

Does it mean that Seulbi is alive?

I think someone keeps on asking
for help from us.

(Is someone asking for help
from the mystery club?)

You.

(Someone calls for them
from the end of the corridor)

- Aren't you Ki Shinhee?
- Ki Sin!

(Shinhee is standing in the middle
of the corridor)

I didn't recognize you because
you're not in uniform.

We saw her in a bright place
and she looks cute.

(Cute)

Her first impression was scary.

It's because she was covered
in something dark.

I thought that I did not want
to know her better.

But she is actually cute.

I knew that you would come.

(Checking out her clothes)

Why are you in school?

I left my workbook at
the self-study room.

You are more passionate about
studying than expected.

The thing that you told us about.

The way to get rid of
the curse.

Yes.

(Shinhee thought them about it
during their first meet)

I know the way to stop a curse.

(This is the method!)

It didn't work.

What should I do? I am 2118.

(Very worried)

Were you lying?

Why would I lie?

Why didn't the candle go out?

How did you do it?

You sure you did it together?

Yes, we did.

Then we turned around
one by one.

(Full of complaints)

You said, 'Congratulations on
graduating' thrice too?

You didn't say 'Happy birthday'
instead, did you?

No.

(Silent)

Are we supposed to say
'Happy birthday'?

No. 'Congratulations on
your graduation'.

(They almost said that, though)

(They did recite the chant too)

Congratulations
on your graduation.

What about the candle?

Candle?

Where did you put it?

We put it in the middle.

It means you saw
the whirlpool shaped drawing.

(What is that?)

The one on the seat?

Yes.

What is that?

It's the symbol we saw
at the bottom of the seat.

Yes. We saw that.

That symbol suddenly appeared
last fall

It suddenly appeared?

After Seulbi's death?

I am still investigating it too.

(Shinhee's recent research topic,
whirlpool symbol)

You don't have
any extra classes today?

What is the time now?

It is 2:30PM.

(It is 2:30. Don't tell me...)

I am late for class again.

It is almost 3PM.

I have to go.

What kind of academy
do you attend?

(Shinhee leaves in a hurry again)

If Shinhee has left,

it means she is not Youdontknowme.

(Who is Youdontknowme then?)

Shall we go?

Where to?

I'm not sure.

(Ms. Duck just wants to go
somewhere without any destination)

Shall we go to the recording room?

Okay.

Is it open now?

(Is the recording room open?)

(When they checked Munbanggu
a moment earlier)

(They visited the recording room)

(Recording room is still being
remodeled. It is not open yet)

It is open. No, it is not.

I think it is locked.

(The door is locked)

(The notice has changed)

'Make an inquiry if visiting
outside of opening hours'.

Shall we go in when it is open?

When do you want to go there?

(The thieves start planning
in front of the room)

(They will go there when it is
open in the Munbanggu)

Something Shinhee said actually
bothers me.

What is it?

She talked about the whirlpool.

Maybe we did not look at it
properly.

- Let's go, help me with my curse.
- But there was

a whirlpool.

Yes. Let's go.

We might not have done it well
as we were scared.

I don't even remember how I
felt when I saw it.

So we went back to turn
the chair over again.

Something that
wasn't there appeared.

Shinhee must have mentioned it

because it was weird, right?

Flip the chair over.

This is my spot.

This symbol is called
the whirlpool, right?

We didn't know it because
we saw it at night.

This does look exactly
like a whirlpool.

I didn't think much
about it before

but now I think it is weird.

What does this symbol mean?

A cochlea?

The cleaner's?

Falling into something?

Whirlpool.

Or is it about looking at
something like this?

(It is like staring at
something from above?)

Pipes look circular when
we look at them from the top.

But why is the line like this
only at this part?

(There is a thick line
only at the start)

It looks like
a mosquito repellent.

I know, right?

Doesn't this remind you
of something?

A target.

Archery?

(That sounds plausible)

To call this a mark...
Something feels off.

(The line never ends but
the target is circular)

Can I take a look at the necklace?

Yes, you can.

They look very different.

Extremely different.

We might find more of this
at other chairs.

Let's check other chairs.

(Do other chairs have
a whirlpool symbol as well?)

Mina's spot.

Whirlpool? What does it mean?

There are none here.

So that is the only one
in this class, right?

Yes.

She said that
this suddenly appeared.

Nobody drew it. It just appeared.

She said it was from
last fall, right?

Yes.

Why did it appear out of the blue?

Fall... What happened last fall?

Seulbi passed away last fall.

Perhaps this has something to do
with Seulbi.

Did it appear before
or after her death?

Since it's fall,
it might be after.

Why did this appear
after her death?

Does it mean that Seulbi
is actually alive?

That is possible.

Is that a sign that
she is not dead yet?

Maybe it's a signal that
she is being locked up?

That's possible.

But why must it be a whirlpool?

(Is she locked up at a place
related to a whirlpool?)

Is she in school?

Archery team?

Gym?

Besides the archery team...

Or is it the archery team's
old dormitory?

Shall we go there?

She has been locked up there
for all this time?

We were told that she
committed suicide.

Or did she leave this symbol
before she died?

Is this a dying message
left by Seulbi?

She knew that she was going to die

and wanted to leave a message?

(Is this a will or dying message?)

'This is unfair.
This is how I died'?

Hypnosis.

Did she fall to her death
because of hypnosis?

(Is her dying message saying that
she died because of hypnosis?)

Did someone make her commit
suicide by using hypnosis?

(They become more suspicious
as there is nothing certain)

Shall we ask
Producer Yong Seungnam?

Did you find something out?

Shall we go somewhere else?

(There might be other places
that have this symbol)

Maybe there is a place or items
that the whirlpool points to.

Perhaps there is some message
left there.

Where shall we go?
Old dormitory? Gym?

(Places to search: Abandoned
dormitory and gym)

(The abandoned dormitory
is locked)

(The gym has archery targets)

Let's go.

(The gym is locked)

The counseling room...

Let's go to places that
we have yet to go to.

Shall we go in again?

(They found the secret area in
the counseling room last night)

What place is this?

(Will they find a whirlpool
symbol in here?)

It is locked. That room
has disappeared.

(The path got locked
within one night?)

Someone did something.

Nobody should enter that area
but we did.

It's because we are ransacking
the whole school.

(The secret area is locked)

(They have searched the
third floor of the main building)

Shall we go to Class 2-1
and open the metaverse?

Yes.

(Staring)

Initially,

when I thought of what has a
symbol that goes like a whirlpool,

I thought of a hydrant.

It has a red light.

The light is circular too.

(She seems to be mesmerized
by the light)

After I told Doyoun about it,

she went, 'Yes!'.

All I could think of is gopchang.

In my mind, a hydrant hose

is rolled round and around
just like gopchang.

Let's check it out.

Is the hose actually rolled?

Doesn't it look like this?

I think it looks like a gopchang.

(Is the hose rolled up
like gopchang?)

There's number 5 written on it.

This is not rolled.

It was not rolled.

It was just like this.

Hold on.

(The mystery club members
walk around to find gopchang)

Every level has one.

Where are they?

(Is the hydrant on the first floor
rolled up?)

(There is no gopchang here either)

This does not look like
gopchang, does it?

It has to be rolled up like this.

I think....

(They found something)

Behind the hose...

There was a diary.

(Fire hydrant on the first floor)

(At the manual diagram)

(There is a symbol that looks
like a whirlpool)

(Inside the fire hydrant)

(They found a diary)

(Flapping away)

Let's go.

Where did you go, Doyoun?

We found this.

(They found a diary while
searching for gopchang)

(They open the diary)

Who is this?

There is someone's picture inside.

Is this Seulbi?

Who is this?

Isn't this Seulbi?

(Who knows how Seulbi looks?)

I saw Seulbi's face from
the student record.

(Is this her?)

I think she looks like this.
She has long straight hair.

(The picture of Seulbi is the
same as the picture in the diary)

This is Lee Seulbi.

Yes, this is her.

(On the last page of the diary)

(is the name of the diary's owner)

(Bi-Bi left a diary)

What is written there?

(On the first page)

'Upload mini game open notice.'

(There are detailed schedule
of her duties at Munbanggu)

She is the admin.

She is the administrator.

(Seulbi is the administrator?)

The winning rate is controlled
to be at ten percent.

(She doesn't just manage but
controls winning probability too)

'Upload notice on the chosen
ones for April Fools' Day'.

'Meet teacher'?

(Even in her schedule for April)

Looks like she meets a teacher
at the end of every month.

This...

This is the same
as Guccilover's diary.

Her diary has this kind
of content as well.

Lee Seulbi's diary

is similar to the diary we found
at Guccilover's room.

Their appointment with the teacher
is written in red

and they also have notes about
events and notices.

Is this diary used
by administrators?

Does it mean that it is
being managed by Seulbi?

Let's see what happened
in the fall.

When did she die in September?
September 30?

What happened before her death?

She died on the day
she met the teacher.

That was her final activity.

Did the teacher kill her?

Let's say Seulbi is dead.

Why did that teacher murder
someone doing a good job?

Is it because she was not
as useful as before?

Or she revealed some secret.

Tell me her Instagram ID.

(They start to find for extra
hints in Seulbi's social media)

seulrain.

There are two underscores.

Lee Seulbi.

(It actually exists?)

It is a private account.

What is connected to this?

Rolling paper?

'To: Myself'.

We went into her social media
account

and saw online post-its
that she uploaded.

2022.

(They check the post-its)

(And they found Seulbi's
secret diary)

March 1 2022.

'Another year has begun
at the orphanage.

I thought that this would be
a boring day as before

but it is different this year.

It is because my guardian
has come.

That teacher has become
my guardian from this year.

I do not know that much
but that teacher seems amazing.'

Is it Mr. Cha Suyeol?

Hurry up and go to the bottom.
I'm feeling dizzy.

February 24 2022.

'I have transferred to my
teacher's alma mater'.

(Alma mater?)

'I decided to hide the fact
that I am from an orphanage.

The teacher is being nice so that
I do not feel uncomfortable.'

So the teacher
was a student here?

Wait. Isn't the teacher
the one who teaches culture?

Culture? Ms. Yujeong?

Did she look at the student
record for organizing reasons?

So now Ms. Yujeong

has Seulbi's record too.

Mina fainted and was taken

to the hospital while she was
with Ms. Yujeong.

The one who accompanied Mina
was Mr. Yujeong, right?

(She even went to the hospital)

I think the teacher who is
the guardian is Mr. Kim Yujeong.

- March 25.
- On this day, Munbanggu...

I ended up organizing Munbanggu
under the teacher's order.

I am proud since my friends
seem to be enjoying it.'

This must be the beginning.

'There is something that gives me
a bad feeling in Munbanggu.

Can I let this continue?

I cannot sleep because
I feel bad towards my friends.

She feels guilty.

It means she was not aware of
all this when it started.

(Oh?)

What is this?

(A black post-it without
any writing)

(If you press it)

(You will find
the fifth secret diary entry)

April 29.

'The teacher got very angry
because of my mistake today.

I should not disappoint
my teacher.

So I have to do better
in the future.'

I guess this is what she does
on the days she feels upset.

(She uses black post-its
to hide her diary)

May 27 2022.

'I got hit by my teacher'.

She was hit?

'Is it hard for me to fulfill
my teacher's expectations?

I studied hard and also did
everything I was told to.

What did I do that was so wrong?

My teacher is very scary.'

'August 1.

I did not know that
the camp is this kind of place.'

This must be the Blooming Camp.

'I was disgusted with what I saw.

I didn't know this is the effect
of what I've been doing.

Is there anything I can do?'

(I see)

Even before I came to
this school, I felt that

Blooming Camp was very weird.

Only some are selected. It is just
a camp. So is that necessary?

Blooming Camp is always involved
in the things we find weird.

They made students fall for
gambling games

and build up debt.

Then it becomes a reason for them
to become lab rats

in Blooming Camp.

'August 3. If I leave things as it
is, my friends will be in danger.

All I can do is to reveal about
the camp and my teacher.

I think someone like Mr. Suyeol
will be able to help me.'

(Mr. Cha Suyeol is mentioned
in Seulbi's diary)

'It is so hard to collect evidence
without my teacher knowing.

I want to collect evidence
as fast as I can

and tell the truth to Mr. Suyeol.'

It means he is aware of
something too.

'September 5 2022.

I told everything to Mr. Suyeol.

But nothing happened.

I am so confused.
What should I do now?

Who can I trust?

I'm lost as I have nowhere
to lean on now.'

He knows about it but
did not take any action.

It means Mr. Suyeol is
part of them.

Mr. Suyeol is either someone
who conspires with them

or just an on-looker.

I knew it.

She was looking at Semi
and Seulbi's student record.

(Ms. Kim Yujeong was reading
two students' records)

(Lee Seulbi)

(And Yoon Semi)

Jihee told Semi that she is
an orphan.

So both of them...

(There's high probability that
Semi has a guardian too)

Semi is the administrator.

(Is Semi the current admin?)

This must be the situation.
'I will be your guardian,

so you should do this for me.'
This must be it.

When they realize this is what
they have to do,

she kills them.

Oh my gosh.

There was a system inspection
on October 1.

Munbanggu's system was down
on October 1.

It is the day
after Seulbi's death.

The system was under inspection
a week after Seulbi's death.

That must be when the admin
was changed to Semi.

Jihee is not the admin.

She just uses Guccilover as
her user ID

and loans cookies.

Did they argue as there were
issues with their work?

I heard them saying, 'Why
did you not do your job well?'

(Jihee was pressuring Semi by
asking about how she worked)

Then she said that Semi
is an orphan.

(She revealed Semi's background
during their argument)

Your mom is not
your biological mother.

We know now that there are
three admins.

(Did Seulbi leave her diary behind
with the whirlpool as her hint?)

She had a feeling that
she would be killed.

Was she wishing someone will find
this as she knows she will die?

She wants to at least
leave this behind.

She doesn't want to see
more victims in the future.

This is like a secret code
that she wishes someone realizes.

It's almost 4PM now.

Let's go.

Let's find out from Youdontknowme
if the admin is Semi.

Who is Youdontknowme?

We decided to not reveal the
information we know, right?

Yes. We cannot trust anybody.

Who can hide this diary?

(They need to be prepared
before meeting that person)

Shall I hide it?

(Inside the padded coat?)

(They will hide Mina's laptop
inside the bag)

(They succeeded at hiding
the evidence)

(They are anxious to meet
Youdontknowme for the first time)

It's cold.

Shall we have some ramyeon
and buy one for Youdontknowme?

Nice!

I want to eat something hot.

Let's make her answer with
something tasty.

Okay.

Youdontknowme is not
Producer Seungnam, is it?

(Oh!)

Yongdonknowme.

Yongdonknowme.

Yongdonknowme.

Shut up, boy. Shut up, boy.

I think we are being too rude
to an adult.

(Their steps become lighter)

(One lady is waiting
for the mystery club)

(Tapping her fingers)

She is here.

(They saw someone seated)

Who is that?
She is listening to music.

(She is also using an apple pod)

(Youdontknowme?)

Hi.

(Hi, my friend)

(This student!)

(Her bag was inspected on
their first day in school)

We are just...

(They slowly spread their fingers
as if in a trance)

You don't know me.

(Desperate)

(You are Youdontknowme,
aren't you?)

How did you know that
I am Youdontknowme?

Actually...

(Blocking her way out)

Mina asked us to help her out.

Mina asked for your help?

Mina couldn't meet you today
because she has something to do.

I heard she's supposed
to meet you today.

What?

Why?

I have an I.S to tell her.

Is?

I.S.

- I.S?
- I.S?

Interesting story.

(I.S. is interesting story)

So Mina is not coming today,
is she?

Let's listen to I.S. then.

No, I just want to go home.

- No.
- We have I.S. too.

You...

You like Mina's brother,
don't you?

(We know about it)

(We know what you like)

Hold on.

How do you know him?

We are very close with him.

You are?

(Unhappy)

I actually don't understand
this situation.

He is definitely not my style.

So I was fascinated.

We even spend time with him
in his room.

(Having fun together)

Okay. Have a seat for now.

You're not lying, are you?

Depending on what you will
tell us today,

what we tell him will
be different.

Okay. I get it.

He's not that great.

What is your name?

Hey.

You don't know me.

You don't know me.

Aren't you reminded of
someone's name?

Suzy?

That's me.

(They are laughing the most
after coming to this school)

(A large ripple)

Do you have only one syllable
to your name?

Su Zy?

I am Bae Suzy.

(Snorting)

Doona. No, Suzy.

Tell us.

You're good.

Lee Doona.

Lee Doona.

Okay, girls.

Tell us your I.S..

(There needs to be give and take)

Okay.

At least you should listen
to this.

You know about Munbanggu,
don't you?

Yes, we do.

We just played the ladder game
before coming.

We lost so much money.

People who play there do
spend lots of money.

It means the whole game
involves a large sum of money.

Mina knows that someone earned
a lot of money through Munbanggu

and started to spend a lot
of time there.

She goes there every day.

I knew it.

All I did was to watch
the events they have.

That was how it should be done.

(Youdontknowme received
an apple pod through an event)

You are amazing.

I saw on the metaverse
that during events,

they actually provide gifts
that are expensive.

Apple pod max?

Youdontknowme.

(Expensive items are given out
at Munbanggu)

Mina has always been curious
about who the admin is.

So I

found out

who it is.

(Get loud)

(As expected from Bae Suzy)

You might end up dating
Mina's brother after this.

Do you want his number?

I put my trust in you.

Tell us.

I will give you his number.

Get closer, girls.

Don't be surprised.

The one who created Munbanggu

is a graduate of

this school.

Isn't that amazing?

Yes. That person wrote 'juniors'.

(That teacher is also a graduate
of Songhwa)

Graduate?

I'm certain that
it is Ms. Kim Yujeong.

It is between the female teachers
as this is a girls' high school.

Ms. Kim Yujeong is
our number 1 candidate.

Ms. Na Hunhwa.

The principal.

But something is weird too

because Mina said that the admin
seems to be a student.

Doesn't it mean the graduate
gets a student to be the admin?

Yes but I'm not sure.

It's because the creator and
admin might be someone different.

I heard a rumor before.

I heard that the admin

is actually Yoon Semi.

What do you think?

- Yoon Semi?
- Yes.

We are certain that Yoon Semi
is the culprit

but we do not have anything
to prove that.

The one who can give us
proof is Youdontknowme.

It's because she said that
she knows who it is.

I was thinking of finding proof
to support our suspicion.

Yoon Semi from Class 2-1?

Yes.

You're driving me nuts.

(Is this just their delusion?)

She is just an ordinary student.

(She failed to get information)

Anyway, I have to go now.

I have to close the shop.

We want to buy something.

The owner is not here.
So you can't buy anything.

How did you open this place up?

I am the famous person of
Songhwa. We are close.

Oh yes. Girls.

Did you see the update
on Munbanggu today?

I heard the recording room
will be open today.

Yes. The update on
the recording room.

Is it open now?

Yes. They are giving prizes too.

(The recording room is open?)

Let's go there.

Anyway, goodbye.

- See you.
- Bye.

Does it mean that teacher
is an alumni?

(Excited penguin mystery club)

This is a girls' high school.
So it is not Mr. Suyeol.

- It is Ms. Yujeong.
- Seems like it.

Let's go to our clubroom
and check it out.

Let's check the metaverse.

Ding, dong.

Ding, dong.

(They are back to their room)

- I got a text.
- From Producer Seungnam?

It's Producer Yoon Seungnam.

(Taking a deep breath)

'Jiyoon, this is about the suicide
case due to bad grades.

I investigated that case.

Student dropped to death at
X High School.

Reason is stress from studying.'

This is from October 3 last year.

'On September 30, a student,
L, was found dead

from falling off the building at
Yeseong-gun.

The late L was believed

to have been under stress due to
sudden bad grades in a mock test

as she came under pressure about
university entrance.

L used to live in an orphanage

and her guardian, K...'

Kim Yujeong.

'With K as her guardian,

L is known to be a student
with flying colors

and her passing is a loss.

Police and other related bodies
have investigated this case

but did not find any foul play.

They came to the conclusion that
L decided to commit suicide

due to the stress that
she underwent from studying

and the case was closed
without an autopsy.'

It's clear
she did not commit suicide.

No autopsy was done.

She was murdered.

'I also found something out
while investigating that case.

There was a major case that
happened at that school before.'

(He provided two articles)

This is from October 1 2003,
on a Wednesday.

It's because she died
on September 30.

'High schooler Lim who is known as
the rising star in archery

passed away from falling
from the school's rooftop.

She was found dead after
falling from the dorm's rooftop.

Last night at around 9PM,

Lim, a rising star in archery,

was found dead at a school
in Chungnam.

During her middle school years,

she became famous for winning
the National Sports Day for Youth.

When she started high school,

she became a rising star
for winning

most of the competitions which
deepens our sadness.

A spokesperson from
the police agency said that

they are currently investigating
the site to find evidence.'

But listen to the next one.

There is an article saying that
she took her own life

released on October 6.

'Found testimony from witness.

Case was concluded as suicide.'

- Witness?
- A witness testimony?

The late Lim's family strongly
insisted

that she does not have
a reason to commit suicide

which prompted police
to investigate the case.

However, two days ago,

they received a testimony from
a witness who saw her last.

Police mentioned that K,
also a student of this school...'

Is she Kim Yujeong?

- It might be her.
- It might be Kim Yujeong.

It's because she is an alumni.

'According to K, she was about
to leave school at around 9PM

and saw Lim on the rooftop

all alone.

On top of that, Lim is believed
to be under a lot of stress

due to her lackluster performance
recently.

She mentioned that Lim seemed
anxious and struggling.'

But she might be lying.

(Confused)

I thought that something
was off with this.

Other information we found about
this parallel universe theory

is that the cases were closed
as suicide.

However, there is something that
is suspicious about it.

'The school mentioned that
they will build

a memorial to remember Lim
in school

by planting pine trees

as they wish to remember
the late L forever.'

There are many pine trees here.

(Songhwa has many pine trees)

(Is one of the trees here
a memorial tree?)

I think K is actually Kim Yujeong.

Yujeong murdered Lim Danbi.

She also made Seulbi's death
look like an accident.

She committed murder as a student

and came back as a teacher

to open Munbanggu

and committed another suicide.

There is something else from
Producer Seungnam.

'This is not reported
in any articles

The day after Lim's death, her
best friend committed suicide.'

What?

'The school kept it quiet since
the two cases

happen one after another.

I talked with the late student's
family

and received a short suicide note.
You should read it too.

Memories in the heart.
Longing for the sky.

Regret buried by your side.'

'Memories in the heart'.

(Memories in heart. Longing for
sky. Regret buried by your side)

This is a suicide note, right?

'By your side'.
Beside the pine tree!

Let's go.

This is a suicide note by
her best friend?

Yes, that is right.

Beside the pine tree.

I'm certain of that.

When I heard that something
is buried by her side,

I thought of the pine tree.

Let's dig up the pine tree.

(They are ready)

Be prepared.

If we step out right now,

we don't know what will happen

and might not be able to return.

- Stay alert!
- Take everything we need.

Put things like heat packs here.

We might need to be digging.

Do we have something
like a shovel?

You're right.

Let's take this too.

(They get flashlights
from their box)

Shall we bring a magnifying glass
instead of a shovel?

(Taking magnifying glass which
has a strong grip)

(They are ready now)

Let's go.

Let's go.

It's dark now, right?

Yes, it is!

The sun has set.

We are doomed.

It should be over there, right?

I believe so.

Let's go! Be confident!

I won't be scared again.

Be alert!

I'm scared.

(The confident duck suddenly
changed)

Which pine tree is it?

I'm not sure.

(But they continue to walk
confidently)

There are so many pine trees.

(Packed)

How are we going to find it?

Yes. This is definitely Songhwa.

(Pine tree forest)

(They secretly enter
the pine forest)

It feels warm here.

There is a shovel!

There is a shovel!

That is a shovel.

We found a shovel.

Let's dig using a shovel.

(However)

(Where should we dig?)

Why is this the only one
that is tied?

Yes. Why only this tree?

(This is the only tree
that is covered)

There must be one tree that is
marked among all the trees.

Yes.

They seem to try to keep
this tree warm.

(They started to dig randomly)

(Oh?)

(Something is hidden under
the pile of snow)

'Forget your short life, become
rain and wash away your sadness.

September 9, 2003'.

I'm sad that she left the world
when things were going well.

Right?

(What secret is hidden
at this monument?)

I'll dig.

Okay.

She said that it is buried
beside Danbi, right?

Yes.

Is it beside this tombstone?

Yes, I think so.

(BIBI uses all her energy)

(Bit it is not easy as before)

I cannot dig well.

(Scraping)

Jiyoon was like a bulldozer.

She was digging using
the magnifying glass.

Here. I found something.

- What is that?
- There's something here.

What is that?

I got it.

I got it.

What is this? This is scary.

I saw something white that
was covered in a plastic bag.

I think it was a
pretty box back then.

However, it had rust on it
and the ribbon was undone.

It made me think that someone
who really liked Danbi

must have buried all
their memories together here.

Let's bring it in
and check it out.

(They decided to bring it
to their room)

The magnifying glass was better
than the shovel.

(Magnifying glass: It is better
at digging than a shovel)

Shovel Jiyoon.

But this is so sad.

It's sad to see a tombstone there.

This is very scary.

(They have a bad feeling from
before they open it up)

If her best friend buried this,

I believe that there would be
information on Danbi.

What's this?

I thought that we would find
something important in it.

Someone took it.

It was empty.

What we did was futile.

Someone beat us to this.

Who is the person who was
one step ahead of us?

Is it Ms. Kim Yujeong again?

(Falling)

The reason we found a shovel

is because someone dug
and took it away.

Someone did that.

(High School Mystery Club 3)

(This case is going nowhere)

(In order to solve it,)

(do not trust anybody)

(Be suspicious of everything)

(This is the only place
to find clues)

(They finally found out)

(the brutality
that has existed here)

(since a long time ago)

This is from 2003.

(People who are trying
to hide the past)

(They are trying to unravel
the truth)

(Although they are suspicious)

(It started to snow heavily
as if to hide the truth)

(They have to unravel the truth
before it is too late)

(This is where everything began)

(They can see light)

(within the dark?)

(A mysterious student ID

We have to go out from
this side.

(However, their path got blocked)

(and are stuck in the worst
situation they can think of)

(Will they be able to escape?)

I'm sorry, teacher.
