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

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

(High School Mystery Club 3)

(Their path to school is covered in snow)

Ms. Yujeong. Can you get hold of Mr. Suyeol?

(Cha Suyeol is missing?)

You should wait a bit longer.

(Something is suspicious about Kim Yujeong)

(They start to uncover the truth behind the part-time job)

Human experiment?

The one who created Munbanggu

is a graduate

of this school.

(Shocking secret about Munbanggu)

Isn't this shocking?

Let's go to the lab.

(Mysterious clue hidden in the laboratory)

(Name written in blood, Lee Seulbi)

(A diary that is hidden in the fire hydrant box)

(The diary belongs to Lee Seulbi)

She is the admin.

She is!

(A record by the administrator, Lee Seulbi)

'The teacher will become my guardian from this year.'

Didn't she say to Semi that Semi is an orphan?

(Munbanggu's current admin is Yoon Semi?)

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

(Is the teacher Kim Yujeong?)

(A will left)

(by Lim Danbi's best friend from Producer Yong)

'Your side'. That must mean beside the pine tree.

Let's dig this.

(Buried in the soil)

(is an old box)

(However)

(Someone took what was inside?)

(What is the secret of this box?)

What? We were too late?

(Empty)

There are no clues at all?

(All clues have disappeared from this box)

What? Someone took it?

Wasn't that necklace the item that was in this box?

Just this necklace in a box as big as this?

I doubt it.

(What was inside the box?)

This is scary. Who took it?

Right?

If someone who wants to hide the evidence took it...

- I bet it is Kim Yujeong. - Right?

She is in school too.

The person related to this case that knows the real story.

Is this the reason that person is back in this school?

She is a graduate who knows everything about the past.

Isn't it Ms. Kim Yujeong?

Give me your hand.

(Only her hands got dirty)

(Proof of how hard she tried to dig)

I'm someone who digs using a magnifying glass?

I thought you were from 'Hometown Myths'.

(Give me back my evidence)

I think we have to go to the record room.

Tomorrow there will be an update about a new space.

Looks like the record room will open tomorrow.

(They wanted to go)

(to the record room as soon as it is open)

Let's check the laptop before we go there.

(Sighing)

Hold on. Let me clean this first.

Okay.

The garbage can...

(It is clear that this is the acorn)

(Wiping)

(Jeez)

We went all out for nothing.

I know, right?

You're done? It's connected?

Let's go.

Let's go.

Let's go, let's go.

(is the record room open?)

It is open.

(There are people waiting in front of the room)

Oh? What is this?

Those are numbers!

There were codes in the pop-up window.

90.01.09...

10.11.10.

The window was just there.

Let's write that down.

January 9, 1990?

(Dates?)

(Key in window and confirm button)

(And a list of random numbers)

(They enter after taking a picture)

Oh?

(Wrong. Please key in again)

(As expected, it won't be easy to enter)

We knew that there will be an obstacle to go in.

There is a big event related to this space opening.

So I doubt we will be able to enter easily.

However, this room is locked.

We need to get the right code

in order for us to enter the room online.

They put a code to enter this room.

90.01.09.

10.11...

What do these mean?

Is this related to numbers or...?

Is this something nonsensical?

There must be a pattern to these numbers.

What are the dots for?

I think the pattern here is a dot after two numbers.

We just need to find the pattern.

(Is the answer in the same pattern?)

The only numbers used are 0, 1, 7 and 9.

Perhaps there's something...

What is the commonality between 0, 1, 7 and 9?

My birthdate is September 7.

(Hmm)

Mine is September 27.

(Cute)

(Focused)

What does this format of numbers refer to?

Hour, minute, second.

- Date and year. - Date and year.

There's 70, so it broke the pattern.

Since it's for the record room, I think it is the year.

January 9 1990?

January 11 1970?

What day is that?

Even if those are dates, we don't know how are they related.

I saw something similar to this in the principal's room.

It has dates from the year this school was established.

(On the day of their transfer at the principal's office)

(Jaejae saw the school's history hanging on the wall)

(Are these dates related to the school's history?)

But this school was established in 1973.

Is it recorded as 1970 in the record room?

What could it be?

(Immersed)

Shall we just key in randomly?

We won't get locked out just because we made many mistakes.

Honestly, this is not a big deal.

I was counting the number of zeroes.

- 15. - 15.

40.22...

- 22? - Yes.

(Please open)

(Wrong)

Fine.

- That was a good try. - We were just trying it out.

- Yes. - Okay.

(They continued to try endlessly)

This is not any kind of coding, is it?

Apparently we can communicate using binary a system.

That's not applicable here as there are 7 and 9.

But the binary system clock looks similar to this.

This is HH, MM, SS.

(They do look similar)

Would this work?

(Something signals that it might take ages)

Mr. Cha Suyeol

- is a math teacher, right? - Yes.

After we lock him up

and tie him,

we will ask him to solve this.

'Tell us right now!'.

(That is not going to work)

What can it be? What is it?

I don't know.

(Struggling)

(This is a room to spend time and build our minds)

(Touching her forehead)

(Knock, knock)

Yes?

(Who comes here at this hour?)

Who are you?

Let's open the door

(Hide the laptop)

Who are you?

I am Lee Jongdae.

Mr. Jongdae.

(Jongdae from admin office?)

Hello.

(What brings him here?)

I was about to get off work

and saw lights turned on at the student union.

- I'm here just to check. - I see.

Can I know what you are doing here?

We are studying right now.

Mr. Jongdae works with the admin office.

The notice at the record room says that we have to inquire

at the admin office if we want to use it outside of opening hours.

We went to the record room

and saw we have to ask the office to use it outside of opening hours.

We would like to check something out there.

It is quite late right now.

(But can you let us in?)

But I think that's possible if you follow me now.

(He agrees to work overtime)

We can just enter the record room ourselves.

I am very grateful for this.

- Just follow me. - Okay.

Mr. Jongdae is very nice.

- He looks nice. - Yes, he has a nice smile.

(Jongdae is not only nice but kind too)

When did he get to school?

I think he came after us.

(They enter the office thanks to Jongdae)

- Can you wait for a moment? - Sure.

(Rummaging)

You are working hard even on a holiday.

Not at all. I came in late as I had work outside.

(Staring)

You have to follow our procedure to use the record room.

- Procedure? - To get the key,

you need to fill in the register book

and pass me your student ID.

- Then I will give it to you. - I see.

Can you please line up in one line over here.

Now I know why people like to call you Mr. Single File.

It's because he likes to make us line up in one line.

Here you go.

(Jaejae is the first to write in the register book)

Today is November 21, 2023. A Tuesday.

Reason for visit?

To learn about the school.

(Even she finds it funny)

Please give me your student ID.

(She gives her student ID)

(Just because)

(To study the history of this school)

(Study history)

(Study history)

(They are ready to enter the record room)

Can we go now?

Yes. I will give you the key.

Did you leave this diffuser here?

I got it as a gift.

(He is one of the handsome men of Songhwa)

When you are done,

please return the key to this office.

Okay.

- Thank you for helping us. - Thank you.

Thank you.

Walk in single file.

Single file.

(In single file)

The record room is scary.

It's okay. At least the lights are on.

All places have lights.

Let's open this room.

(BIBI naturally stands in front of the door)

(Peeking)

Doesn't BIBI look like an expert at picking doors?

BIBI, you look experienced.

Done.

(Clanking)

(Wow)

This is high-tech.

(Wow)

(Record room)

(History of Songhwa)

(Attendance book from 19**)

I thought that the record room was a place where documents

are kept just like how it was at Taepyeong.

But it is high-tech and most are stored digitally.

There is an LED screen too.

The names of alumni who are successful.

(List of individuals who helped Songhwa to develop)

I thought that the remodeling

of the room was futuristic.

(Amazed)

Why is this set up so well?

- Strong with power of chamsong. - Strong.

First graduation certificate.

(Staring)

Yena.

Ms. Kim Yujeong is not listed as the graduate of this school.

You are right.

(Ms. Kim Yujeong is not in the list of helpful individuals)

There is no proof that Ms. Yujeong

is an alumni of this school.

(Anything that can be our evidence?)

(Thinking)

(Oh)

(This is where you can find Songhwa's history)

(Songhwa digital museum)

(When they click on 'Introduction to Songhwa)

(A scary black and white portrait)

- This is scary. - Touch it.

President's speech.

(Something is weird)

The president is Jeong Jonghyeon.

The president is Jeong Jonghyeon.

Jeong Jonghyeon?

I thought that he looked familiar.

(Jong Jonghyeon, president of Songhwa Girls' High School)

(Will they find something else?)

(Oh)

What is it?

What is the matter?

I suddenly heard a sound.

(The school song is suddenly playing)

This must be it.

(School song is turned off)

(Flapping)

(She barely gets to calm herself)

I think we can watch that again.

I was shocked because it suddenly made a sound.

(Clicking on 'School emblem' again)

- Will the song play again? - Yes.

Will we find something under 'Music score'?

(So we checked it out)

(Songhwa Song Contest)

(Participants: BIBI, Park Jiyoon)

(Participants: Choi Yena, Jang Doyoun)

5, 6, 7, 8.

From the depths of Goyosan, getting energy from the pine tree.

(Park Jiyoon / Conductor)

The awakening of Songhwa.

Why are they singing?

Go.

Spread.

(Songhwa Girls' High School)

(They sang the whole song)

Something is missing here.

(They became just singers)

(Let's just find clues now)

Good.

Songhwa's history.

The 70s.

(It began with Songhwa's establishment in the 1970s)

(The history records stops in the current year, 2023)

This must be that.

They look the exactly the same.

Yes, they are the same.

They are the former principals.

(They found a list of former principals)

(Here is the principal who wants to be trendy)

(Oh)

(Songhwa development history in pictures)

(History of Songhwa)

It was built in 1973.

(Songhwa Girls' High School after being built in 1973)

(Chairs for the students to use are lined up)

(The abandoned dormitory that was used by the archery team)

(This is the picture of when it was a new building)

Former clubs.

(Former clubs)

Let's see.

This is a list of former clubs.

(The clubs are listed based on year)

Occult club.

'One more person besides Gi Shinhee.

Active from March 2022 until August 2023.'

(Thinking)

Did they list us too?

No.

I hope they updated it.

Mist Club is right here!

'Defeat villains and bring about justice'.

(Mist Club)

Everything we wrote was shown on screen.

'Defeat villains and bring about justice'.

Anyway, we have left our trace in this school.

I hope that our success

will live forever like a legend

through our juniors that join this club.

Shall we take a picture with this as a memento?

Updated moment.

I'm happy.

I feel like we have been acknowledged.

(STBY)

Wait. Make sure our club is visible.

I think we can know even better

if we enter this room in Munbanggu.

(What is the meaning behind these hints?)

349 people.

(Jaejae is suddenly taking pictures of the wall?)

While the others were looking at the digitalized history record,

I believe that there is a reason the years are listed.

(Jaejae is looking at the years all by herself)

Are 90, 10, 70, 10, and 00 all related to years?

(History of Songhwa)

Does 01.09 mean that it is January 9?

But nothing was listed in January.

(No record of January of 1990)

Perhaps it is not January

but referring to the first line instead?

I was hesitant about it.

Girls. This was what I was deducting just now.

I was looking at the 9th syllable of the 1st line of 1990.

It was 'seon'.

I then saw the 10th syllable on the 9th line for 2010.

It is 'che'.

(The answer is related to those syllables?)

Read out one by one.

11th syllable from the 1st line of 1970 is 'in'.

(10th syllable of the 7th line in 2010)

It is 'gyo'.

The final one is the 1st syllable of the 7th line in 2000.

It is 'da'.

So the answer is 'seoncheingyoda'.

Seoncheingyoda.

Let's key that in.

It doesn't make sense.

(Seoncheingyoda)

(Wrong. Please key in again)

Was I wrong?

(She counts it again)

'Seonche' is the word.

(Sighing)

(What could it be?)

Hold on.

Let's add spacing too.

I was looking at the years.

Seoncheingyoda.

Are we supposed to count the spaces as well?

The first line from 1990.

1, 2, 3, 4, 5, 6, 7, 8, 9.

Hae.

The second is...

7, 8, 9, 10.

Deu.

(70.01.11)

(Rib)

(10.07.10)

(Ni)

(00.07.01)

(Da)

After doing it again,

we got 'haedeuribnida'.

Haedeuribnida.

That is the name of an old club.

(The answer is an old club?)

(This is what they found from the digital museum)

Volunteering Club, Haedeuribnida.

'2 people plus Kim Yujeong. From March 2003.

A volunteering club that helps our peers.'

It was a club located at the basement of the dormitory.

Kim Yujeong? That Kim Yujeong?

It is Kim Yujeong.

So Ms. Kim Yujeong

is an alumni and is back in school as a teacher.

She was also in a club back in 2003.

The student named Kim Yujeong who was in this club

is now Ms. Kim Yujeong who is the advisor of the investment club

and the creator and main admin of Munbanggu.

Everything just fell into place.

(Is the final dark secret)

(Ms. Kim Yujeong?)

Haedeuribnida.

(Please be right this time)

(Correct)

- We got it right. - We can go in.

(Watching closely)

We saw this picture earlier.

This is the old dorm's building.

It was so clean.

Did something happen while she was in the volunteering club?

Especially since there is a picture of the dorm.

Is it because she wants to tell about what happened when she

was in Haedeuribnida?

'Something related to this happened.

I want you to be aware of it.

Why did they only have a volunteering club at that time?

It was only for seven months.

They existed only until October.

This club disappeared after the death of their friend.

Listen to this. 'Witness, K,

was on her way home from school at around 9PM

when she saw Lim walking up to the rooftop all by herself.'

The movement fits.

Her clubroom is located in the basement of the dorm.

She left her clubroom and was on her way home

when she saw her friend going up there all by herself.

(Jiyoon's deduction: K is a member of Haedeuribnida)

That student is Kim Yujeong.

- Ms. Kim Yujeong. - Kim Yujeong is K.

I think something happened within the club.

That resulted in one person's death who is Lim Danbi.

Then it caused another girl to commit suicide.

What happened in the volunteering club?

(What happened in Haedeuribnida?)

- I think we found everything. - I think so too.

(Complete conquest of the record room)

(Getting goosebumps)

Yujeong... I have to be quiet.

Shall we return the keys?

Yes. Only then we can get our student IDs back.

(Their precious student IDs are waiting in the office)

We need to return this and get our student ID.

He is not there.

- What? - He stepped out for a bit?

- What is that? - 'Be back in five minutes'.

(The admin office is empty while they were at the record room)

Something is suspicious.

This is fishy. Where did he take our student IDs too?

- What is the matter? - CCTV!

- Where? - We were observed!

What?

Let me see.

- They were observing us. - Right?

(The CCTV has been observing them?)

(Cafeteria entrance)

(Corridor of archery team's dormitory)

(Songhwa's student union)

(Club room's corridor)

(Four cameras have been observing the student union)

Are these just meant to prevent crimes?

But why must the CCTV be faced towards our room?

That is also the corridor where Mina passed by.

The archery team's dormitory corridor.

Why is there a CCTV here?

(This is the path that connects to the corridor they saw Mina at)

The corridor that goes towards our clubroom.

I don't mind that since that is a corridor.

The path to the door that goes to the old dormitory

is being observed by CCTV.

Why are they filming that?

It's because that place is always locked.

That is where Mina continues to pass by.

Is Mr. Jongdae related to this case as well?

Is he an accomplice? That was what I thought.

(Why is Jongdae watching Songhwa's student union?)

Look at this.

All snacks are lined up in one line too.

- I got goosebumps. - I got goosebumps.

He has an obsession.

Let's spread out.

Hello.

Hello.

What were you doing?

(Feeling guilty)

We are here to get our student IDs.

(It's their first time to see Jongdae being cold)

(Being wary)

You shouldn't look or touch people's things as you please.

We are sorry.

(Peeking)

- You can give me the key. - Here you go.

(Being submissive)

He asked why were we peeking at his table.

I admit that we were wrong

but he was so rude about it.

(Unhappy)

(Complaining despite being in the wrong)

He is scary.

(Standing in one line)

(They get their student IDs after lining up)

- Here you go. - Thank you.

- He is sensitive. - Scary.

- He is strict. - Yes, he is.

- Here you go. - Thank you.

(Sliding)

(Two teachers enter the admin office)

Thank you.

I was flustered since Mr. Suyeol didn't show up.

- Good evening. - Good evening.

What are you doing?

We are about to leave.

- You are? - Yes.

We wanted to have a meeting in the meeting room

but we ran out of coffee in the teachers' office.

So we will take some from here.

Please go ahead.

(Staring)

Thank you.

- Have a good evening. - You too.

- You should go home. - Mr. Sanmun.

Mr. Suyeol did not come today?

I can't even get hold of him.

Do you know something?

No. We are just curious too.

- We'll get ahold of him later. - Okay.

(Both teachers head to the meeting room)

- Ms. Yujeong looks like a robot. - She is very scary.

- Thank you. - Thank you.

Don't you feel like going to the meeting room and spying on them?

Let's follow them secretly.

Or we can go there while they are away.

(Ah)

- Go to the teachers' office... - Ms. Yujeong's table...

Shall we?

We went to the teachers' room after they left.

It's because

that is the only way for us to find clues.

(Taking a deep breath)

- Go to the teachers' office... - Ms. Yujeong's table...

Shall we?

There are teachers there.

(Frozen)

Let's go.

(They start moving again)

(Goodbye)

Let's take a look at the document form earlier.

Yes. The one she was looking at since morning.

Which was it? Where is it?

It was here. The key...

It is locked.

(However, her desk is locked)

(How do we open the desk?

- The key. - It is locked.

Ta-da. I found it.

(Did Yena find the key?)

(Rummaging through the pocket)

(Found it)

I saw the key in Ms. Yujeong's pocket.

(Teachers' office after getting to school)

(She kept Seulbi and Semi's school records in the drawer)

(Then she kept the key in her pocket)

(I am watching)

(Genius Yena's reconnaissance is a success)

You are so amazing.

This is it.

(They become even more meticulous with their stealing)

(Inside Ms. Kim Yujeong's drawer)

(is an envelope)

(They turn on their radar)

Lee Seulbi and Lim Danbi.

(As expected, they found Seulbi and Semi's student records)

Both of them are recipients of welfare assistance.

Isn't this crazy?

I got goosebumps.

(Welfare recipient)

It was suspicious to see her check their student record.

It feels like they are thinking

about what to do and how to dispose of those students.

Anything else underneath?

(There's more here?)

We found

an extremely old key.

We also found a diary that seems like it will

disappear with just time.

Encyclopedia of Danbi.

(They carefully open it up)

What is this?

(From information on Danbi's physique)

Why does she have this?

(Danbi's daily schedule)

(And her preferences too)

(Why does Ms. Yujeong have this?)

It's true that she was close with Danbi.

(Grabbing)

What is this?

Let's just take pictures instead of taking this.

(They knew right away that they have to take pictures)

We took pictures. Let's go.

- You got everything? - Yes.

(They quickly close the drawer)

(Mission complete)

Hey! That...

Cha Suyeol!

(His name bothers them)

Seulbi had a feeling

that she was going to die and was struggling.

So she told everything to Mr. Cha Suyeol.

She made a confession.

However, nothing happened after that day.

It means Mr. Cha Suyeol

is either a an onlooker or a sympathizer.

It means we need to find evidence

that he is either an onlooker or sympathizer.

Let's search his place too.

(It feels good to search the place of someone they are suspicious of)

I am so suspicious of him.

There are a lot of letters.

(His table is filled with letters from students)

(Dragging)

Are you certain that this is not important?

(Searching)

It felt like my heart is about to explode.

That one at the end there. No.

(The first drawer is empty)

(They are bending down to search for evidence)

Shall we take all of these out?

We can remove it?

Why?

There's something under the desk.

There's something there.

We found nothing despite searching.

I wondered what should I do.

So I kept on opening and closing the drawer.

When I opened the drawer,

suddenly something fell off.

I was surprised and peeked.

There were so many things under it.

So I immediately took everything out.

There is something underneath.

We found it after raising this.

(Grabbing something else)

(A hidden space under the drawer)

(What items are these?)

What are these?

(Very shocked)

These look like important pieces of evidence.

There are also gloves covered in blood.

Take a picture of this.

What is this?

Whose are these?

- Kim Yujeong. - Ms. Kim Yujeong.

(They found Kim Yujeong's resume with the phone)

She did graduate from Songhwa Girls' High School.

She attended this school from 2002 to 2005.

This is most suspicious.

Let's get going.

(Their mission is truly complete)

(They put the chair back)

Anyway, this...

- I knew he hid something. - Handsome brats

- should not be trusted. - I had a bad feeling.

(Being wary)

Let's walk in single file.

(They become very obedient in front of Jongdae)

(Walking in a single line)

We did it.

We did not bother him.

(They quickly head back to their room)

- This is crazy. - It's mind-blowing.

- This school is crazy. - It is.

Let's read everything for now.

Have a seat.

I knew that Suyeol was like this.

There is a cellphone over here.

- Where were these? - Over there.

(Cellphone that is hidden inside the desk)

- Why? - We don't know whose this is.

Cha Suyeol?

'I am Cha Suyeol from Songhwa.'

'I am Cha Suyeol from Songhwa.' This is the first Blooming Camp?

(He sent the picture of the first Blooming Camp to someone)

The first Blooming Camp

was on September 7.

I am sending this as I think you should have a look at it.

Replay.

Hey!

Hey!

(Someone is screaming scarily in the recording)

(And there is sound of someone being beaten?)

I am sorry, teacher.

- 'I am sorry' and what? - Teacher.

I am sorry, teacher.

'I am sorry, teacher'.

He sent this to 'Money Source'.

He was asked what he wanted and he said 'Cha Suyeol'.

This is what Cha Suyeol used to threaten this person.

He looks normal and educated

but saved someone's name as 'Money Source'.

The messages I read after that was even scarier.

He gave his account number to that person.

There was a phone call at 8PM yesterday.

(A record of a phone call with Money Source at 8PM)

Shall we call this number?

But what should we say then?

We can just dial and be quiet.

Let's just end the call after that.

- Shall we call this number? - Let's do it.

(There is a signal)

(Ignore the duck)

(Nervous)

This person is not answering.

(Not answering)

Yesterday at 8PM,

we were in school.

- Oh? - Why?

You're right.

Cha Suyeol called this person after knowing what happened.

(Last night, Cha Suyeol opened the door to the lab)

(After shooing them away)

After looking at the bloody scene,

he must have called Money Source.

This time...

you have to pay me more.

'I will let you know if something happens.'

He contacted that person so that he could get more money.

Who is this person?

Who is Money Source?

First off. Mr. Cha Suyeol

knows that Ms. Kim Yujeong is this school's graduate.

(Kim Yujeong's resume is in Cha Suyeol's drawer)

He knows that she was here from 2002 until 2005.

Does it mean the one who shouted was Yujeong?

Hey!

(Is Ms. Yujeong the one who shouted in the file?)

I am sorry, teacher.

(Who is the one who got hit?)

Since this girl called that person 'teacher',

I guess she is a student.

Isn't it Lee Seulbi?

September 7 from last year.

He sent this text on September 7.

This file is from May 27.

Just now...

Hold on. May.

The rolling paper.

(Checking Seulbi's rolling paper from Yena's phone)

This is from May 27.

'I was hit by the teacher'.

The girl is Seulbi.

(The recording file is the same date as the day she was hit)

So

Seulbi was hit by Ms. Yujeong.

Suyeol found out about it and used it to threaten her.

Kim Yujeong becomes his source of money.

So Cha Suyeol is not the one to expose Munbanggu.

He knows that Kim Yujeong

is the person behind Munbanggu.

He found out while consulting other students.

Mr. Cha Suyeol

is not happy with the salary as a government officer.

He is

a nasty and dirty person who wants to earn money.

He is a nasty person who

has no thoughts of even comforting the students.

We found out that Ms. Yujeong is the main figure behind

organizing part-time jobs and gambling.

In my opinion,

something happened to Mr. Suyeol

because of Ms. Yujeong. That is why he can't show up.

Kim Yujeong is still in school.

Since she is in school,

she is pretending to be normal in front of Mr. Sanmun.

You are right.

Look at this.

The file that Ms. Yujeong has

on Lim Danbi.

(Encyclopedia of Lim Danbi)

It is called Encyclopedia of Danbi.

This was made by hand.

There are many pictures that were taken from a distance.

Initially, we thought that she is very close with Danbi.

Danbi does not like beans.

Look at this. Here are the beans that Danbi hates.

Danbi's hair.

I think this is love, not like. This is a one-sided love.

When I saw the hair, I could tell that something was wrong.

Organization chart of the archery team.

She even has information on her rival, Lee Sihyeon.

It says she is allergic to apple and almost died.

She did research and

found out about her allergy to apples to kill her.

Health room strategy.

What does this mean?

'This is the Health Room Strategy.

Find out when the gym is empty on Sunday.

Make a copy of the key to the locker room

to check Danbi's locker.

Then, cut the bowstring.

That will increase probability of meeting Danbi in a week.'

What is this?

- Because it's Haedeuribnida. - Volunteering job.

She pretended to do a volunteering job to meet Danbi

and purposely cut off her bowstring too.

Was she hoping that Danbi would ask for her help?

(She strategized to make Danbi come to her?)

It means Yujeong is Danbi's stalker.

I think she was a stalker.

(Sighing)

She is a stalker.

She was obsessed.

I realized that this feeling is wrong.

This is not just a good thing.

This is dangerous.

I'm getting dizzy. We found a lot of things.

I'm confused.

Let's look at the letters.

(Among the many letters that were written to Danbi)

We read what Ms. Yujeong wrote.

'To Danbi. Danbi, how are you doing up there?

It has been a year since you left us.

What are things like without me?

My year without you was tough.

Do you remember the day you won the tryouts?

You don't know the reason Sihyeon suddenly forfeited, do you?

I can do anything for you.'

Allergy to apples.

'But why did you avoid me?

Why did you deny our relationship in front of others?

I believed that we share the same feelings.

If this is how you'll treat me, why did you smile at me?'

This is so scary. It sounds like misery.

'Why did you stomp on my heart?

Did you use me because I can do anything for you?

You know that I can't be happy without you, don't you?

Our last day.

Under the dark sky.

I can't forget how precarious and sorrowful you looked.'

Precarious and sorrowful?

'If only I could turn back time.

In the end, I'll try to go after you.'

- What? - See you. September 30 2004.'

(Doesn't 'See you soon' mean that she is going to die?)

This is not written by Yujeong but by her best friend.

(A text from Producer Yong Seungnam)

'After the death of Lim,

her best friend committed suicide.'

This means that Yujeong was not the stalker.

- Yes. - What is this then?

The dead girl was the stalker.

'Hi, Danbi. I am your avid fan.

Each time when you ran on the field every morning,

our eyes always met. Do you remember?

I left you a letter since I doubt you know my name.

Please remember my name from now on.

My name is Yang Yejin.'

- Yang Yejin? - Yang Yejin.

(Yang Yejin dies after Danbi)

Yejin died after Danbi.

It means Yejin buried this.

Yes.

But that...

So Ms. Yujeong was the one who dug this out.

I guess the box was filled with this and letters.

- Yes. - And she dug this out.

This is the reason she locked her drawer.

So it means that Yang Yejin murdered Lee Danbi

while stalking her.

She killed Danbi as something happened between them

and she then followed suit.

Yujeong was aware of that.

Why is Yujeong back here?

She wants to be reminded of the pain from the past? Why?

What is her goal?

- What is her reason? - Why create Munbanggu?

Why did she make Munbanggu?

- What is her reason? - I know, right?

Is it true that Ms. Yujeong created Munbanggu?

But she is the only alumni.

But someone else

among the teachers might be it too.

Some other female teacher might be the creator?

We can think of this as an alternative too.

We need to keep our options open.

She has been digging everything up again

and this is not helpful to Munbanggu at all.

This is more interesting.

What is the relationship between Blooming Camp and Munbanggu?

You are right.

In Munbanggu

Those students who are unable to pay back

are listed in Blooming Camp as they can't pay using cash.

Then they become lab rats. I think that is true.

I think that is the right connection.

But why does Ms. Yujeong...

(Knock, knock)

(Someone is here)

(Getting busy)

Who is it?

- Delivery. - Delivery?

(Very suspicious)

We didn't order anything.

What are you delivering?

(Very wary)

Fried chicken?

Fried chicken?

Who ordered this?

- I don't know. - You don't?

- Enjoy. - Thank you.

(Smiling happily)

Who sent that?

I have trauma with fried chicken.

This is from Pelicana.

- That looks good. - This looks tasty.

(Who ordered this?)

Notes.

'Mr. Sanmun told me that you are in school.'

- What? - 'Eat this while you study.

If you cause trouble I will resign.

KBK'.

There he goes again.

He is obsessed with trying to look cool.

We have been walking around the school today

which made us hungry.

The shop was also closed today.

- My gosh. - Our teacher.

I cannot believe this.

- Our teacher. - This is crazy.

I don't have much appetite but why the ruckus?

(Happy)

(She is happy too)

Does Mr. Bongkwon think that

we will like this if he does this?

This is ridiculous.

Let's make a fan club when we have time.

(I like that)

(Grimacing as it is tasty)

Thank you.

(Crunchy)

(Chewing)

(Yes)

(Happy)

This is tasty.

(Kim Bongkwon Fan Club has five members)

- I am full. - This is delicious.

Ms. Yujeong is the organizer for Blooming Camp, right?

That is organized by The Young Beauty.

The Young Beauty?

(The organizer of the camp is written on the poster)

(What is Songhwa Blooming Camp?)

(Sponsored and run by The Young Beauty)

I don't think Yujeong can do everything herself.

If she's going to do something weird during the camp,

the principal and head of student affairs know of this.

Definitely yes.

There will be others who are involved in this too.

They might be the ones involved in The Young Beauty.

Let's organize what we have now.

Please write nicely.

Let's do what Jiyoon says.

Write down Lee Danbi, Lee Seulbi, and Yoon Semi.

Seulbi.

Seulbi.

Write 'admin' under Seulbi and Semi's name.

Write 'admin'.

- Use a different color. - Marionette.

A different color?

Write 'admin' in a different color.

Use a different color.

Use a different color as that is their job.

Write this in a different color. Haedeuribnida.

(Write down, marionettes)

Haedeuribnida Club.

(Confused)

Who was the one who opened the record room?

Since Yujeong and Semi are the founders,

it must be them.

Why did they open that?

Why was the room opened?

I wonder what the reason is.

Why were we told to find out about Haedeuribnida

by making it the passcode?

(Why were they told about Haedeuribnida?)

Isn't it because Yujeong would like this to be known?

She wants us to know about the secret of Danbi's death.

Are there two sides of the story?

- Although she's involved? - Feeling guilty as an onlooker?

I don't think that's the case.

She might just be someone evil.

But listen.

We have to go back to the fundamentals.

Every crime has its own benefit.

The benefit points towards their goals.

- So what is the reason - What is the point?

she created Munbanggu?

You know maybe what she wants

is to bring those without family members here

pretending to support them but actually pulling them in this.

Wasn't that her goal when she first started this?

- That is possible. - You are right.

It's like how a victim becomes the perpetrator.

She might have been used in the past case too.

(Is Ms. Kim Yujeong a victim as well?)

(Searching for something)

What is this?

(What is the truth behind this necklace?)

Don't you think this is related to Blooming Camp?

I believe this is going to be key evidence.

The cherry on top.

- A mark. - It might be the camp's symbol.

- Or tattoo. - The Young Beauty.

The Young Beauty?

(Anyway, this is related to The Young Beauty, isn't it?)

Mina left this at the pawnshop.

She left this there to earn money.

Perhaps Mina might have

stolen this.

It's because this becomes some sort of evidence.

Mina found out the truth to a certain degree.

Then she stole it

and placed this at the pawnshop as she needed money.

Yes. She got some money after giving this to the pawnshop.

She did another part-time job on the 13th.

That was our first day of school.

Then we saw her that night.

What's clear is that

she did so many part-time jobs recently.

She might have died as it was affecting her health

or someone murdered her.

What's certain is that she is in danger.

So this item is related to

Munbanggu's admin and Blooming Camp.

(Their discussion continues longer than before)

Why does Mr. Suyeol have this?

All evidence is left in the acorn.

(What is this?)

(Mr. Suyeol has a phone that is stained with blood)

Whose phone is this?

- Shall we turn it on? - Okay.

I can't turn it on.

I have a vague memory about this.

But back then

we saw a cord coming out of Mina's locker.

Yes.

That looks similar to this, doesn't it?

You are right.

Something was peeking out of the locker.

The first time we searched Mina's locker.

there was something like cords coming out of it.

We found that out that those were hanging from her phone.

Looks like this does belong to Mina.

By the time we actually think we found her...

Unfortunately, I think she has passed away.

(Who is the person that murdered Mina mercilessly?)

Mina is now dead.

Can I draw a small 'x' by her name?

How do we resolve the remaining mysteries?

This was our mission for today.

'Unravel the Bi-Bi parallel universe theory'.

(Unravel the Bi-Bi parallel universe theory)

(Bi-Bi parallel universe theory)

(Their names both contain the syllable 'bi' meaning 'fly')

(Died on September 30)

(They chose to commit suicide by jumping off somewhere)

(The final commonality between them is 2118)

(Student ID number 2118)

How do we unravel this parallel theory?

What else can we do here?

Is Kim Yujeong related to this theory?

(Is Kim Yujeong related to this parallel universe theory?)

I think we can get more information with the key we found.

- Key? - Use the key.

We found a key there.

We found an old key in Ms. Yujeong's drawer.

We almost left it there but we got a bad feeling.

(Will they be able to unravel the theory using this key?)

Ms. Yujeong was in that club.

- Haedeuribnida? - Yes. Haedeuribnida.

That club used to be in the basement.

Yes. The archery team's dormitory basement.

Basement of the archery team's dormitory.

(Gosh)

What key is that?

No.

Perhaps that is the key to the abandoned dorm

that we have always wanted to go to.

I guess we have to go there.

(Losing her mind)

I knew that we would need to go there one day.

Today is the day.

I'm scared but let's go.

This is so scary but we have to go there.

We can do this.

Oh my gosh.

We don't have any other choice, do we?

- Are you scared? - Yes.

- I am scared too. - Let's hold hands as we go in.

Let's go.

(Let's close our eyes and go)

(Walking stealthily)

Yena.

(Wait. We have to walk out of this place?)

This is very scary.

- I think I am going to pass gas. - This is ridiculous.

You did that already, didn't you?

No.

I have mentioned that this day would come

since the first day we were here.

And that day is today.

(They knew from the start they'd have to enter this building)

(On this late night that is covered in snow)

Let's just go there with this key.

Then we head out right away.

Why is it snowing and making this even scarier?

(This is even scarier with the snow)

How are we supposed to even enter this place?

No. We have to go in to get justice.

- Bring justice, defeat villain! - Bring justice, defeat villain!

(Courage gauge)

(Sighing)

(This building makes them lose their morale)

Isn't this the key to the lock?

(Is the key in the drawer for this lock?)

- No, it doesn't fit. - We have to go there.

I think it's for there.

(There is another entrance to the abandoned dorm)

(They do not want to do it at all)

We have to walk through the overpass again?

I think I was wishing that the key was for the main door.

The place we have to run to

is further away from here.

(They enter the student union using a long path)

(Striding)

Jiyoon, you are so cool.

(Confident)

Jiyoon, you seem different.

I will show you a different side of me.

Jiyoon.

(Jiyoon leads them to walk through the overpass)

(Determined)

Why do I hate this so much?

(All this time)

(they were never able to open this door)

(Will they be able to open it this time?)

Is it unlocked?

(The door is still open)

This must be the key.

- This must be it. - Yes, it is.

(The key has found its lock)

(Closing her eyes / Scream)

(The abandoned dorm is open)

(This place has been abandoned after it was shut down)

It is filled with dust and spiderwebs.

We don't even know what might have happened here.

This place gave me the chills.

There are real ghosts, you know.

I thought we might find them here.

(Getting chills)

I closed my eyes.

I didn't want to feel anything.

So I had my eyes half shut

and walked around like this.

I think we have to go to the rooms in the basement.

Let's go down.

Jiyoon, why are you so brave?

Jiyoon is stronger now.

Why is it so far?

(There is an iron door deep inside the basement)

Let's open and check it out together.

(Is this Haedeuribnida's room?)

This room is sound-proofed.

One person hold the door as it might get shut.

(Nervous)

There is a music stand here.

(A music stand on the floor?)

Why is it sound-proofed?

I guess this was a recording room.

Why must this room be sound-proofed?

(A room that is covered in sound-proof material)

Why is there water on the floor?

Isn't that because this room is in the basement?

Band club. 'You are noisy'.

This is the band club's room.

(Among the list of clubs from the past)

(There were two clubs that use the same basement)

Where are the partitions in this basement?

Did they share this space together?

I doubt it.

I think they complained about the noise as they are close by.

Are they one level above?

But a level above means it is not in the basement.

It was written that there is a clubroom in the basement

but there was only one room.

Is it a room in a room?

You don't think there is a hidden space here, right?

(Knocking)

There is an echo here.

(Pressing hard)

You should kick this, Yena. You did that before.

This is a door.

- Wait. We can remove this. - This is a door.

- Wait. We can remove this. - This is a door.

We removed the sound-proofing material

and we found something that looked like a plank.

We wondered what that was.

(They ripped the material off as they felt suspicious)

(Ripping)

(Ripping)

What is this?

That is when we found a door.

(A door is hidden behind it)

I found it.

(Yena the genius has been doing great the whole day today)

There is something down here.

Wait. We can tear this apart.

This is it.

(Yena's Mystery Club to be continued)

- It is unlocked? - Yes.

(They open the door)

What place is this?

(They open the hidden door)

We could tell that this was an old clubroom right away.

This place must have been locked for the past 20 years.

(Haedeuribnida Club's room)

What kind of place is this?

(This place is covered in dust as it was not used for a long time)

Communication box.

(Communication box)

I bet 'Haedeuribnida' is pasted somewhere.

(Hae)

There is 'deu' here.

(There are pieces of evidence of this club everywhere)

This has been here for ages.

What is in there?

In that place.

Aren't the lights on there?

(There is another door connected to this room)

(Why are the lights on?)

There is a student ID on the floor.

(They can see a student ID behind the window)

There was another door on the other side.

We saw a student ID on the floor

but we couldn't open the door.

The door is locked.

How do we get that?

- Maybe with the key? - Shall we try it, Jaejae?

There is a student ID out there.

I think we can use this key again as it is the same building.

- Oh? - You can open it?

Maybe not.

Must we find the key here too?

(Jaejae found something on the desk)

(An old camcorder)

There is as camcorder here?

Yes but this place...

I think we need to find the battery. Is it here?

Battery?

I bet it is out of battery as it has been left for ages.

Is this the charger?

- Charger? - There is a charger.

Let's give it a shot.

Let's connect this.

- It fits. - It does fit.

(The camcorder is working after it is being charged)

(Looking around)

I am so scared. Can you please...

There we go.

There we go.

(BIBI, the one who can solve small issues)

Thank you.

There is a play button here.

(Once they press the play button)

This is a video of the school.

What? You are filming?

You look good.

Let's continue doing this.

- Please introduce this club. - Introduction?

Hurry up.

(An unfamiliar face who is wearing a familiar uniform)

Okay.

The club that we have established is

Haedeuribnida!

That is this room.

(This is a video of when Haedeuribnida was active)

(They are standing in the same place)

We are here to listen to requests and worries of our friends.

We are a volunteering club.

Hey!

What are you doing?

What took you so long?

(Another student enters the room)

- Three down. - Three down?

(What does that mean?)

This is the space for the three of us to discuss.

The most important part is

please write down your request and leave it in this box.

I hope we get many requests.

(The next video plays)

(This is their first time to get a request)

They are like us.

'Name. Han Jeongseo'.

- Hey. - What?

I am so excited.

There is another person that was not there before.

One person has changed.

We can see all of their faces right now.

She has been filming all this time.

One of them is Ms. Yujeong.

'I like this guy from the school next door.

Please give him this letter for me.'

(Their first task is to deliver a love letter)

This one?

Who are we supposed to give it to?

Chunri High School. Cha Seongju from grade 12.

My gosh!

Cha Seongju and Han Jeongseo.

'Stairway to Heaven' is from 2003.

But this is fascinating.

We actually do get requests.

(Later, someone left chocolates in their box)

- Guylian. - That is delicious.

Remember the one who gave us the love letter?

Things went well between them.

- They are dating now? - Yes.

So she gave us chocolates to thank us.

I cannot bring myself to eat these.

Shall we keep this?

They are cute.

I guess this is the reason they filmed this.

They were at their peak back then.

It felt like we were watching ourselves.

It felt like we were watching ourselves from season 1.

We were very cute, innocent and pretty.

They received many requests.

I think news about us spread

because of the couple we helped.

(They get many requests after that)

They are more famous than us.

Seong Yura from Milliore Queen.

said she is joining a dance competition in August.

She needs us to become their one extra member.

(This time, there is a request to join the dance team)

Not me. You know that I am stiff.

Me too.

You're the only one left.

- Just me? - Yes.

Really?

Let's leave this to Baek Yeohee then.

Baek Yeohee?

One of them is called Baek Yeohee.

It means Kim Yujeong is either the girl with short hair

or long hair.

There is another one here.

- What is that? - Let's check it out.

Her name is Yang Yejin.

(Client's name: Yang Yejin)

Let me see.

Her name is Yang Yejin.

That name is familiar.

Yejin likes Danbi to the point she became a stalker.

She is the one who has unrequited love for Danbi.

We happened to get to know about her request.

She wants to show support for Sihyeon for the next tryout

and asked us to give her these cookies.

Why didn't she give these herself?

I don't know. She can't make it as she has something to do.

This is an easy request. So let's give it to her.

Okay. Got it.

(A few days later)

- There's a request? - Yes.

Baek Yeohee. Milliore Queen has won.

They left some prize money for us.

Amazing.

There's $30.

(This amount was a lot back then)

I barely danced but they gave us this much.

What envelope is this?

I don't know. there is no name written on it.

'Things went well thanks to you.

I will send more requests next time.'

Who is this from?

(A food voucher that was sent anonymously?)

- VAPS food voucher. - Amazing.

- This is the best. - Wonderful.

(They don't know who sent it but they love it)

By the way, have you heard about this?

(Listening closely)

Do you know Sihyeon from the archery team?

She suddenly withdrew from joining the tryout.

Really? Why?

I don't know. I heard it is because of an allergic reaction.

Apples! Allergy to apples!

Those must have been apple cookies.

The voucher must be from Yejin.

She got rid of Danbi's rival by using her allergy to apples.

We know the weakness

of Danbi's rival.

Allergy to apples.

(Danbi's rival's weakness is her allergy to apples)

She asked someone else

to send the apple cookies

on her behalf without using her real name.

The result is clear.

The opponent ate the cookies and got an apple allergic reaction

which caused her to withdraw from competing.

Danbi must have won again.

(The video that gives them a bad feeling ends)

Let's go.

(Video from a month later as they get endless requests)

This is from Yoo Seungyeon.

A request to make a poster for the Uri Geller Descendant Club.

Promotional poster? That takes too much effort.

Okay. This is the second one.

She wants to lend make-up for her date with Chunri High.

Let her use yours. You have lots of makeup.

No. These are expensive.

A rift is starting between them.

She has become rude.

Jeez.

Hong Minjeong asked us to buy cigarettes.

She is so brave.

Buy cigarettes?

I think they end up

becoming like assistants to them.

She wants us to do that for free?

She asked if it is for free?

Why did they become weird?

She said that she will give us an Iruver MP3.

Iruver MP3?

We should do it then.

We are Haedeuribnida who do everything.

They started to receive things like VAPS food vouchers.

- They know the taste of rewards. - They become twisted.

They no longer have the same values as before.

They become materialistic.

As time passes by, looks like

they seem to have become corrupted.

They started the club with good intentions.

But the VAPS food voucher...

The food there are good.

After they had a taste of the food there,

they continued to receive rewards for what they did.

That is when things went wrong.

Remember Hong Minjeong

who asked for cigarettes? Did she leave us something?

They bought cigarettes.

She just ignored us after that.

Let's not take any request from her again.

What are you talking about?

We are a club that is supposed to help others.

I don't think it's right to spend our time and money though.

Who is that? The band?

(Who is that?)

Excuse me.

I'm here to make a request.

You can just write in your request.

Since you're here, have a seat.

You do not expose

who made requests to you, do you?

No.

All of our requests are secret.

So tell us your name first.

Yang Yejin.

(Yang Yejin)

Yang Yejin?

I think you made a request to us before.

What is it this time?

Tonight,

can you please help me

get into the archery team's dorm?

Archery team's dormitory?

Only members of the archery club can enter at night.

You think I don't know that?

Aren't you a club that would do anything for others?

Well, that is true.

Their coach manages this place at night.

He has the key too.

You...

Didn't you receive a VAPS food voucher before?

That was from me.

I can give you something better this time.

Her request is easy.

I think I can do it.

Hold on.

(They have conflicting opinions on Yejin's request)

There's something on my face. Look at this.

Hello.

Hey.

I told you to reject her request.

What are you talking about?

Lim Danbi.

She died.

So what?

Are we the reason she died?

Do you think I don't know that you were helping Yejin?

Hey.

All I did was to give her the key.

How do I know that this would happen?

It was obvious that her request was weird!

Do you think this is the reason we started this club?

Why did you do that?

We were just doing our club activities.

Think carefully.

What good will this do for us if people know about this?

Okay. Let's just keep it quiet.

You really...

Hey.

Where are you going?

Hey!

That is all.

They let her in to the archery team's dormitory

which might've caused her to feel guilty.

It means that this is the key that they gave to Yang Yejin.

They gave her this key that we have now.

Yes. That's why they hid it.

(Time capsule that Yejin buried 20 years ago)

Ms. Yujeong took everything that was in the box

and we took the key

that let us into this place.

Which one is Kim Yujeong?

What's clear is that the girl in the middle is

Baek Yeohee.

One of them is Yujeong but which one is she?

I think she is the girl with the fringe. The kind one.

She looks somewhat like her.

She was someone kind

so why is she acting this way now?

Is Ms. Yujeong not the one who is doing all this?

Is it possible that she was just

observing them closely?

Maybe she thinks that they are the ones in danger now.

I think the one who is too obsessed with being

materialistic is now an adult who is doing all this.

- It's her. - The girl with short hair.

She is not the principal, is she?

- She does look like her. - Na Hunhwa?

But they don't look like they are of the same age.

(It is hard for them to tell who these students are)

I'm curious to know if Yujeong is the one who has

a sense of justice or the one who is materialistic.

Since she has some knowledge about the case,

she has come back and became the guardian to these orphans.

This action sounds more similar to the materialistic girl.

However, she might return here in order to protect them.

The dark secret that we are not aware of.

One alumni

is still here and hurting others.

Yes.

(Who is the alumni who is back and still materialistic?)

They were very happy here

but somehow things took a bad turn.

Let's make a promise.

We shall never change our motto to stop villains and bring justice.

- Never accept weird requests. - Yes.

Fried chicken...

But that was from our teacher.

Shall we give him some money for that?

Okay.

Is there anything else for us to find here?

We don't want to come back.

So I hope we can find all hints here today.

They were doing something great.

Why did they get a VAPS food coupon?

Why is the light over there turned on?

(That looks like a machine room for heaters and pipes)

(There is one item that does not seem to belong here)

Why is there an ID on the floor?

Since there is a student ID here,

doesn't it mean that someone has been coming to this place?

I think we have to take that ID.

We have to take it.

Shall we go out?

We have to go out of this building?

Or we can use something

to get that.

We need something like a stick.

(There are air vents in the door)

Girls.

Girls.

Hangers.

(There are hangers by the door)

(Turning it into a stick)

(Oh)

(The stick is ready in a jiff)

Let me take a look.

(Jaejae is the eyes)

(BIBI is the hand)

Do you think this fits?

(The stick is here)

(It is a success)

(BIBI, Jiyoon)

Just a bit more.

You're doing great.

You got it.

This is like fishing.

Slowly.

Stop. Press.

Press on it to pull it here.

(Trembling)

This is too weak

(It is not strong enough to drag the card)

Wait. Let me try.

(Jiyoon's stick is in)

(Crouching as she is immersed)

Good. That looks good.

You just have to hook it now.

To the right.

Just a bit more.

Let me try one more time.

(BIBI, Jiyoon)

Okay. I got it.

- It worked. - We got it.

It's coming.

It's coming closer. Good.

(The student ID is stuck on the hook)

Good.

Wow. The hook.

We needed to use a hook.

It was like Doyoun's leg from those days.

We dragged it in

by using a hanger.

(Wow)

That was fascinating.

(They got the student ID)

- Yoon Semi. - Yoon Semi?

(What is Semi's student ID doing here?)

Semi's student ID was found dropped just like Mina's.

Yoon Semi. Hwang Mina.

(Did something happen to Semi just like Mina?)

We found the student ID of the one we suspected as

the admin who is Semi.

It feels like she is going through something dangerous.

Where is Semi?

Let's go in for now.

We have checked that this is Semi's ID.

We...

There's someone here.

What is that?

Hold on.

- Who are you? - What is happening?

Isn't that Semi?

It's Mr. Cha Suyeol.

Mr. Cha Suyeol!

- Are you okay? - That is Mr. Cha Suyeol?

Why? What is the matter?

Mr. Suyeol, we are the Mist Club.

Mr. Suyeol!

He got beaten up.

There's someone here!

There's someone here!

What? What did you say?

What was it?

- Are you okay? - Is everything okay?

(High School Mystery Club 3)

(A mysterious car comes closer in the dark)

Isn't that Mr. Ki Bongkwon?

(They got betrayed by someone they trust)

Where are they?

(The dark shadow is coming closer to them)

(To survive)

(They have to run away)

(With heaving breathing)

(And quick steps)

(They are so close to escaping)

(Will they be able to escape from the villains' hands?)

The school feels creepy today.

(Songhwa is very scary)

(Soon is their closing ceremony)

Why do I feel that something is wrong?

(One by one)

(People are disappearing)

Are you sure today is a school day?

(They look around)

(But this school is so quiet)

- Jaejae. - Yes.

Please come with me.

(Mr. Sanmun is trying)

(to frame the Mist Club for the theft in school)

(She suddenly became a thief)

Transfer students.

Follow me.

(She secretly approaches the mystery club)

Stop digging around.

Don't tell people about me and Semi.

(Unhappy)

What is this?

(Their room was attacked)

This means we have to go head-to-head.

(They have nowhere else to go)

(They face another truth)

We can see the CCTV, right?

(They have been under surveillance?)

(The marauder is closer)

(that they think)

(Being under surveillance became part of their life)

(Everything is a lie here)

(Does it mean there is nobody)

(they can trust?)

(The criminal left another trace)

(That person is hiding somewhere in the school)

(Will they be able to stop the evil deeds?)

Semi? I think it's Semi.

This is very scary.

Oh no. What is this about Semi?

I think we have to save Semi.

My gosh.
