"S LINE" (The red thread connecting people who have had sexual relations)

Seo-ah

Kang Seo-ah, open your eyes

Kang Seo-ah

(Central Operating Room)

Where's Seo-ah

Why were you at school at that time

I went to find Seo-ah

You went to find her?

She called me

Said she was going to school

Why go to school at that time

I don't know either

I’m unclear about the rest

But Seo-ah...

Definitely didn't commit suicide

The language teacher still hasn't come to school?

Call him quickly

How can he be late on a day like this

I did call him but he didn’t pick up

How exactly are you all disciplining the students

How can something like this happen at school

If you want to die, just do it at home

Why choose to jump at school

Dean of Studies

Aren't you going too far saying that

And that student is still alive, okay

Mr. Lee, did you do anything right to say such things

You are responsible too, okay

Yes, I am responsible too

Aren't we all the same?

But why blame the students?

I didn't blame the students.

You clearly said it's the students' fault.

- I understand Mr. Li's position - Did I say anything wrong?

- Please discuss it with me directly - Mr. Li, stop talking

This isn't an issue for Mr. Li to pursue

It's not my responsibility to pursue this with you

Are you okay?

In any case

This matter

Try not to let it spread

Please keep it confidential, teachers

He smells like smoke

Your teeth will turn yellow that way

Your teeth are so yellow, they're like burnt rice

Hey

Why isn't Kim Hye Young at school?

What a coincidence, as soon as Kang Sun Ah fell, she's not coming to school

Maybe school is too boring, so she doesn't want to come

I don't know

Teacher, it's all my fault; it's a student from our class

It's not your fault

Isn't she the student who nearly triggered the anti-bullying committee last time?

By the way, the language teacher still isn't answering the phone?

I know, it's odd; he's never done this before

Ugh, it's so frustrating

Isn't there any good news?

It's always bullying, suicides, these terrible things

Mr. Kim

I'm here.

Didn't you say you were going to propose?

Have you decided on the wedding date yet?

I don't plan to get married anymore.

(Apartment)

Just put it over here.

Yalu, say hello to your uncle.

You should greet people when you see them.

This is for you.

Yalu.

Are you feeling shy?

Is that all your luggage?

I'm only staying here for a week before leaving.

I've sent the rest of my luggage ahead.

Why are you suddenly going to Canada?

Leaving behind a perfectly good job, really...

Have a seat.

This is your first time at my place, right?

How do you feel about it?

It's quite nice.

You moved here last year, right?

No, I've been here for over two years now.

Time really flies.

I owe it all to Mr. Kim Byung-chul.

Should I call him brother-in-law?

What did you say?

I'm staying over; did brother-in-law say anything? Is he okay with it?

Of course not, you're my brother!

Besides, he's very busy with his work.

You probably won't have many chances to see each other.

Let me see

Okay

You said you'd continue working at the school until you go abroad, right?

Yeah

Hold on a moment

Kang Sun-ah

You might as well get up and yell at me

You're looking for evidence, aren't you?

Kang Sun-ah

I know her quite well

She's not your ordinary tough cookie

Suicide

What a joke

And Kim Hye-young, who enjoyed bullying Kang Sun-ah, didn't come to school the day after the incident

That's highly suspicious too

Who are you

I'm Lee Kyung-jin from class five

Assuming this wasn't suicide but murder

The most suspicious would be those closest to her

Because Kang Sun-ah was ostracized

No

Thinking back, she recently made some new friends

She's not dead

What

I said Sun-ah is still alive

Ah... right

Sorry

By the way, you're quite familiar with her too

Where did these glasses come from

I got them made at the eyewear shop

When did you get them?

Last year.

Why haven't you worn them before then?

Because wearing contacts makes my eyes uncomfortable.

Teacher.

What's up?

Do you know whose glasses these are?

Not really sure.

What's going on?

Nothing, just found them at my spot.

Then they must be yours.

Try them on, they seem to suit you.

Okay.

Sorry.

I should have checked in with her earlier.

As the homeroom teacher,

I didn't even know what was on the students' minds.

So do you think she committed suicide?

What?

Currently,

it's not determined as a suicide.

Either way,

if there's anything I can help with, I will.

Please feel free to let me know.

The student who bullied Sana before,

are they still at school now?

That student now...

Are they missing?

Yes.

What about this student?

I found this in Sana's bag.

It seems to be taken on the day it happened.

Are you Lee Ji-won?

Yes.

I'll just get straight to the point with you.

What's your relationship with Sana?

We don't have any relationship.

If there's no relationship,

why would you take photos and go on dates together?

She was the one who asked me out first.

And you agreed just because she asked?

Yes.

It's just...

It was interesting.

A person who used to be outcast suddenly changes completely.

I knew she was interested in me.

Was there anything unusual when you were together?

No.

It was quite normal.

What did you do at the cafe?

Can I be honest?

We talked a bit and then kissed.

I wanted to take it further,

but she refused.

Then where did you go?

Oh right.

After taking photos,

she suddenly ran off like crazy.

She said something was missing.

(Han Ji-uk)

(Wu Dongshi)

(Sinwu Green Park 2)

Let's raise a glass, everyone

Okay

I'm sorry for suddenly showing up and intruding like this

Oh, come on

No need to be so formal

Brother-in-law

Can I call you brother-in-law?

Yes, feel free to call me that

But you know

You two don't really look alike

He's way too handsome

Cheers

Can I ask you something?

Sure

I heard you were about to get married

Why did you suddenly break up?

Honey

Don't ask that

It's okay, just a moment

We were living together

But before the wedding, I saw

I came home early from work

And found her in bed with my friend

This person, no

Our brother-in-law

Wow

You did really well

It's better to find out such things before the wedding

That's why people say it's the ancestors' blessing, right?

I really admire it, truly admire it.

Come on, have a drink.

Alright.

Pour one for me too.

-Is it okay? -Yeah.

The drink is finished.

I'm really

sorry.

It's fine.

It's the work things.

Messages keep coming.

Brother-in-law.

What subject do you teach?

I teach English.

very nice

sounds good

Well, because of my job,

I often interact with foreigners.

By the way, brother-in-law,

Do you know what foreigners love the most when they come to Korea?

Do you know?

Take a guess.

You haven't been in touch with your sister for a while, right?

Yes.

I don't often pick up her calls.

Yes.

Keep in touch often from now on.

After your parents passed away,

it's just the two of you depending on each other.

It's just the two of you left to rely on each other.

Yeah

We should keep in touch more

Oh, excuse me

Nope

Ugh, pressed the wrong button

Brother-in-law, where are you going?

We're on the 10th floor

Okay

Brother-in-law can't hold his liquor well

Brother, this isn't suicide

You can't just sweep it under the rug without investigating

Detective Han, what do you mean by sweep it under the rug?

The doctors at the hospital said the same thing

Said there was no external force involved

Let's be frank

You...

Did you know your niece was being ostracized?

It might be suicide, you punk

That's why it should be investigated further

It might not be just a simple suicide

Ji-yuk

The higher-ups want us to stop

The school foundation is extremely annoyed

The school is already overwhelmed just dealing with the suicide issue

And you want to bring in a murder case?

That's too far, kid

I understand your feelings more than anyone

Try to turn a blind eye

Please?

If it were your child lying in the hospital, would you do the same?

You little brat...

You've crossed the line now

You crossed the line first

What

Hey, Han Ji-yoo

Han Ji-yoo

(Enter password)

Darn it

Bro, it's unbreakable

Even the US side says it's difficult

(Lee Kyu-jin)

You're wearing glasses now

They suit you

Thanks

Looks like there's still no news from the language teacher

Exactly

Teacher, you...

If... you found out someone close was cheating

What would you do

As for me...

But can you be sure what you saw is true

I'd want to tell everything

And watch how dramatic things unfold

Just like a morning drama

Okay

Though you were shy at first

Is uncle your favorite now

You should also hold mom's hand

That's really funny, so funny

-Who is Woo Tae-seok -What

That was sent to the wrong address.

But the address is correct here.

No, it's for Room 401.

Sometimes the address is written wrong.

-I'll take it over. -No need.

You and Ya-ryu go inside first. I'll take it over.

Just leave it in the management office.

-Okay. -Hmm.

Ya-ryu, do you want to try it?

(Recipient: Wu Taixi)

(To: Room 1002, Building 613, Insum Serenity, Phase 3, 22 Jeongunam-gil, Seodaemun-gu, Seoul)

Room 401?

Yes, dear.

I'm already at the door.

It's so heavy, my hands could break.

Didn't you say I could buy anything?

Another package came.

It's not mine.

This is your package.

This one? Not sure.

(Wu Taixi)

(To: Miss Guo Cailin, Room 401, Building 613, Insum Serenity, Phase 3, 22 Jeongunam-gil, Seodaemun-gu, Seoul)

Guo Cailin

Ya-ryu

Come pay respects to grandma.

Okay.

Come pay respects to grandma.

-Where's brother-in-law? -What?

Said he's in Gumi.

Can't make it back today either?

If he goes to the Gumi factory

he usually stays two or three days before coming back.

Sis, are you happy with your marriage?

Yes, I'm happy, just like anyone else.

Raising kids while living my life.

Sis, you should go to a dermatologist for some care.

Your husband earns so well.

Kim Jung-woo, you've changed a lot, you even nag now.

Mom should see you like this.

Jung-woo.

You…

The reason you two broke up.

Was it because her family criticized you for being parentless?

It's not because of that.

Didn't I tell you? She was two-timing.

But it's nice to honor mom together with you.

When we honor dad next time too…

Sis, you wouldn't still be in contact with that family, would you?

Well… it's just that…

Sometimes when uncle calls…

Sis, are you out of your mind?

After dad's affair, how did mom manage?

Did you forget all that?

What are you thinking by staying in touch with them?

No, I just…

You were young back then, you might not know…

I was planning to marry Soo-yeon as we had planned.

After living together for six years, I thought I'd overlook it.

Because they said it was just a momentary lapse.

Because they said it was a momentary lapse of judgment.

She cried even harder, saying it was all her fault.

But starting at some point

Dad's face would always come to mind.

Dad probably admitted his mistakes at first too.

Is this how mom feels?

My favorite face

Every moment it overlaps with the person I hate the most.

I still love Su-yeon.

I miss her a lot.

But because of dad, I can't face her.

Even if that person is dead, they continue to torment me.

-Crazy, right? -What's going on?

Is this true?

Not a single day has been calm.

Unbelievable

-Never expected this -Is it really him?

-The language teacher... -How could this happen?

Hey, come over quickly...

It's Kim Hye-young and the language teacher.

What are we going to do?

Stop fooling around.

You were backstabbed by the language teacher.

(No entry, under investigation)

I'm the language teacher at Ark High School, Bang Seong-jin.

During this period, I maintained an improper relationship with students.

I feel very sorry to my family.

When this was exposed

I could not bear the accompanying shame and guilt.

Therefore, I want to end my life.

Therefore, wanted to end their life.

For the trouble caused by my actions

I sincerely apologize to everyone

Bro, don't touch that

I am wearing gloves

(Will)

What did they say about the estimated time of death?

Well...

Although it needs confirmation after the autopsy

It looks like the body has been here for at least three days

It seems like the person didn't die here

What?

The car was just left in the middle of the parking lot

And it was only found three days later. Is that reasonable?

The photo was posted on the school website today

This means he knew it would be revealed in advance

Someone is definitely behind this

Hey, class leader

We're going to eat spicy rice cakes. Want to join us?

-Sure -What?

What's going on? You usually say no

Are you interested in me?

Or interested in our friend Xianxi?

(Ark High School)

Hey, get in the car

Who are you?

Who is he?

Community resident

You can't park here. Hurry and get in

Hey, mister

Who are you to tell us whether to get in or not?

Uncle?

Yeah, uncle.

Isn't this kidnapping?

Who would kidnap someone in broad daylight like this?

You must be a crazy uncle.

Hey, call the police.

Quick, get the police here.

Want me to call the police for you? Hold on.

Oh, the police are here.

Get in the car quickly.

You're her friend, so why haven't you visited her?

I'm not doubting you.

You said it yourself.

She had no reason to commit suicide.

Why do you think Seon-ah went back to school that night?

Excuse me, have you seen

Seon-ah's glasses?

Glasses?

Hey, explain it to me clearly.

What exactly are those glasses?

Is Seon-ah also related to those glasses?

Please

find the glasses.

Then I will tell you.

What are you going to tell me?

Taxi.

The keys are in the car.

Oh, let's go.

Are you satisfied now?

Before eating.

What is this?

Ah, what is it?

What is this?

It's so beautiful.

Doing this is really embarrassing.

Hurry up.

Let me help you put it on.

Come on.

Let's eat.

Hey, brother-in-law, it's Jungwoo.

Ah.

Hey, little brother-in-law, what's up?

Are you busy?

Yes, well... I'm in a meeting.

It's not convenient to take a call.

Where are you?

Right now?

I'm not in Seoul.

Well... I'll call you later.

Brother-in-law.

I can't reach my sister.

Oh, really?

Um, I...

I'll try to contact your sister.

Alright, hanging up now.

-Hold on a bit longer -Okay

Excuse me, who is it?

Room service.

Hello...

L-little brother-in-law.

Let go

Let go

What are you doing?

What do you think you're doing, brother-in-law?

Well...

Brother-in-law, this situation...

This situation can easily be misunderstood, that's true

This is my privacy now...

No, that's not what I mean

This won't do any good for your sister

You certainly are bold

Shouldn't you apologize first and admit your mistake?

Okay

Okay, I'm sorry, I...

I really can't defend myself

Wait

I understand

I... I'll handle this today

I promise

But please give me some more time

I really will keep my promise

Alright?

Please resolve this by today

Otherwise, I really don't know what I might do

Brother-in-law...

Don't tell your sister, okay?

When can we meet again after you go to Canada?

We've finally gotten in touch, we can meet anytime

Nowadays, abroad isn't so far away

I'll call you often

You need to keep in touch with me.

You too. Call me if anything comes up.

If Yalu wakes up without her uncle, she's going to cause a scene.

It's not much money.

Just take it and use it.

-I really don't need it. -Let's go.

Has your brother-in-law contacted you yet?

What?

He'll come back when the time is right.

Seems like he's busy with something.

We'll be in touch.

No need to see me out.

Morning drama…

Did it get resolved smoothly?

No, it didn't.

I'm not really sure.

Probably.

The school is in chaos right now.

Even you're leaving.

I've got mixed feelings.

Thanks so much during this time.

By the way, have you found Kim Hyejin yet?

No, not yet.

Who uploaded that photo?

Well…

Many people could have.

And I heard the photo's been circulating on students' social media for a while.

(Ms. Gwak Chae-rin)

Gwak Chae-rin

Let me help you put it on.

Come on.

(#PregnancyAnnouncement #WelcomeBaby #SeeYouNextYear)

This lunatic

The number you dialed is unresponsive…

Hello, what are you here for?

My passenger wants to go inside

Sorry, driver, please wait a moment

Hey, customer…

-What's going on -Quickly call an ambulance -Hurry

-119 -Call 119 quickly -Get the police

-Oh my god -What's happening -Call the police

Why is that person doing this?

Hurry and call the police

-What actually happened -Oh my, pull yourself together

-Oh my god -What happened

-I said call for an ambulance -No, really…

-I mean… -Please, stay strong

What do we do now?

Sister

Sister, are you alright?

Sister, open the car door

She's getting out…

Are you okay?

Sister, I'll handle this

Sister, stay with Yalu…

Jung-woo, why did you do this

What do you mean by this?

What's wrong?

Why did you do this?

Sister, why are you doing this?

Why did you do this after all?

What's going on, damn it!

- You... - Brother

Yeah, are you okay?

Brother, she suddenly drove and kept ramming us.

It's okay, it's okay.

Let go, you punk!

What's going on?

Are you even human?

What the hell are you doing now?

Let go, damn it!

Don't do this!

Don't do this, Jung-woo!

Damn it!

What does he mean by that?

They seem like lunatics.

Let's go.

That person isn't my husband.

That person isn't Kim Byung-chul.

That person's name is Oh Tae-sik.

He's that woman's husband.

He came because he was afraid I'd kill his pregnant wife.

Jung-woo, I...

I...

I'm the other woman for that man.

What do you mean by that?

Isn't that what you said?

Tell him to deal with the mistress and go back to his life.

Jung-woo saw me with Chae-rin.

He told me to end this relationship.

Chae-rin is pregnant too. I think that's the right thing to do.

Why is the car driving like this? It's broken down.

Mom

Uncle, why are you crying?

Is Mom not feeling well?

No, it's nothing, Yalu.

How can someone's will be written so carelessly?

A will…

A will

Where are you going?

Home

Isn't this your home, brother?

(Hotel)

(Urgently hiring counter staff, any age, beginners welcome) (Guarantee same-day pay, must be punctual)

Hey, sunglasses

Why aren't any of you answering the phone?

Are your phones just accessories?

The glasses you mentioned, are they these?

The ones Sana wore

Aren't they the glasses you were talking about?

What exactly can you see when wearing those glasses?

S-line

S… line?

(Lee Soo Hyuk)

(Arin)

(And Lee Da Hee)

So you're saying someone took Sana's glasses

called her to the rooftop

and then pushed her off, right?

But it seems she used the ability to see the S-line

to threaten many people

There are people without any sexual experience over there

Teacher, do you have a girlfriend?

I've had sexual relationships with many men lately

What are those glasses that would cause this?

If you wear those glasses

You can see who you've had sexual encounters with

Another random murder occurred last night in the Jiangyan Cave area

Is it possible

There's more than one pair of glasses

Are there…several pairs of glasses?
