I said, get in.

Kang Seon-a, get in.

I told you I'm not getting in!

Seon-a.

Ugh, what an attitude.

DATING AGENCY FOR ETERNAL SINGLES

There are things you don't need to see in life.

No. Things that shouldn't be seen at all.

I've always seen these lines.

POLITICIAN'S SEXUAL ASSAULT REVEALED

Could we get a statement?

- STAR'S INTERVIEW - Not at all.

She's special to me, but we're just manager and actor.

As I grew up, I naturally found out

what these lines meant.

What did you write?

I also discovered that I was the only one who could see these lines.

I was a cursed child who saw what others couldn't...

DAD, ME, MOM, AUNT

And also a child who drove her mother mad and killed her father.

The red lines that were always there,

slowly started to make sense.

The moment I realized

that seeing the red lines could kill people...

I shut my mouth and closed my eyes.

I wanted to give up on everything...

but I didn't die.

I survived every time as if god was toying with me...

and one day, I found myself completely alone.

I made a decision then.

If I have no choice but to live,

I had to find out why these red lines existed,

who had created them,

who else was watching them besides me,

and how I could get rid of them.

Hello? Is anyone there?

I moved into the building across the way a few days ago.

I wanted to pass out rice cakes to the neighbors,

but people don't really eat them anymore these days.

So I bought some fruit, instead.

Do you like fruit?

I never used to eat fruit when I was younger,

but now I can't get enough of it as an adult.

I'll just leave it here.

Make sure you eat them before they go bad.

BANGJU POLICE STATION

Shit.

Hey. I'm sorry.

What?

Never mind. Later.

Don't tell me you scratched my car again.

What's the occasion today?

Why are you here at this hour?

I know, right? It's pointless...

I was trying to be a good uncle for once.

This is why people shouldn't try new things.

Oh, that niece in high school?

High schoolers act like kings these days.

Fucking royalty.

But what can you do? I'm all she has.

What happens if you get married?

- "Married?" - "Married?"

You'll come to my wedding, won't you?

Why would I go to your wedding?

Because we're coworkers?

What?

Nothing. Just something that came to mind.

I thought you were a sex addict.

Isn't it too late to be picky?

My apologies.

Seon-a, didn't I tell you to stop acting up?

Why all this so far away

Hey, give it to me.

Come here.

I told you not to be a smartass.

Asshole.

Seon-a, are you okay?

Does it hurt?

Lift her up.

Seon-a.

You won't even bring me the money I ask for.

So why would you report me?

It was you, wasn't it?

Grab her.

My god. Seon-a.

Seon-a, you need to get beaten up a bit more.

Get up.

Get up! Shit.

Hey.

I heard your uncle's a cop.

It's obvious, isn't it?

And why are you ignoring my calls and texts?

She's fucking heavy.

Did you make fun of me?

If you report me again,

I'm really going to push you off here.

- Oh, hi. - Hi.

Victim?

She's a 29-year-old woman who lived alone.

She worked as a manager at a nearby cafe.

Family?

No siblings. Parents are still alive, but in the countryside.

Lover?

Nothing confirmed yet. I'll look into it.

The place is a complete mess, but all her belongings are here.

The body is clean.

It almost looks like a stage set.

Oh?

This place is nice.

Is it famous?

No.

It's a local spot.

Check this out.

Yes, sir.

Inspector Han.

We got a statement from the first-floor neighbor earlier.

They saw a man with a helmet

heading towards this woman's apartment late last night.

Helmet?

They said he looked like a deliveryman.

But I can't figure out

what this guy's objective was.

The money was untouched.

There were no signs of sexual assault.

She doesn't seem like the type of person people would hold grudges against.

Maybe it's just a psychopath?

Does such a psychopath exist?

What about the restaurant?

We confirmed she orders from there often,

but no order on that day.

What about her love life?

Did you look into it?

They say she had one,

but apparently, it ended about a year ago.

Should we look for him?

I JUST ORDERED A LITTLE TOO MUCH

The dead body of a woman in her 20s was discovered in her apartment complex

in Sinu-dong with signs of strangulation this afternoon.

The police reported signs of a break-in

and began investigating this case as an opportunistic robbery and murder.

With the recent string of murders in Sinu-dong

involving women in their 30s who lived alone...

People with hundreds of S-lines are rare and stand out,

but that doesn't mean I miss people who only have one.

Especially if that person

is trying to eavesdrop on anything at a crime scene.

No, I didn't hear anything strange.

These days, deliveries are made on motorcycles day and night.

Even if we see one lurking around, we just assume someone ordered food.

112. What's your emergency?

The place across from mine... The man with the helmet...

Hello?

Today's topic is balances in ecosystems.

Let's say a gray wolf starts eating a town's livestock.

The residents become furious

and ask for permission to hunt the wolf.

What do you think happens?

The wolf will start to hide its tracks.

So you're just not going to show up?

- What the? - What is this?

- What could it be? - Open it.

Clothes?

Shit, you scared me.

Why didn't you go to school?

Uncle.

Can I have some money?

You can have this for now.

I'll give you more tomorrow.

How much more can you give me?

Hey, why's your face like that?

Are you getting beat up out there?

Why do you care?

- How much more can you... - Why do you need money?

- Ji-uk. - Yeah. What?

Listen. Someone filed a report yesterday

mentioning a man wearing a helmet.

But the possibility of the suspect being a deliveryman was never released to the public.

- You got the caller's location? - Hold on.

Sinu-dong.

Wanseong Apartments, Building B?

Wait, isn't that where you live?

Building B?

BUILDING B

I'm Inspector Han Ji-uk from the Bangju Police Station.

Is anyone home?

I've never seen someone with so many S-lines up close.

Hello.

You're wasting your time. She won't come out.

She's famous for being a recluse.

She even has someone else throw out her trash.

I just need a moment.

You filed a police report yesterday.

Can you just tell me what you saw?

This could serve as crucial evidence

in a murder case that happened in the vicinity.

A teenager?

Are your parents home?

It was done by accident.

Pardon?

I called 112 by accident.

Can you give me more details about that situation?

I saw a man with a helmet enter the building across the street

and thought the woman was in danger.

aren't you a teenager?

Woman?

Your next-door neighbor.

The woman who moved into apartment 204.

There have been a lot of incidents lately...

But,

it was her boyfriend.

But,

Shouldn't you be at school?

What's wrong with kids these days?

But how did she know I lived there?

BUILDING B

KIM-HYE BITCH

I SUGGEST YOU COME TO SCHOOL TOMORROW.

DON'T FORGET THE MONEY.

fucking bitch...

Hurry up.

What's wrong with you?

Let's keep going, okay?

- This is really amazing. - I know, right?

- Isn't this fucking awesome? - How much was it?

- I didn't buy it this time. - Did your mom buy it? Or your dad?

Don't be stupid.

They're dead.

Ji-uk.

You know that ex-boyfriend of the victim from the Sinu-dong murder...

His name is Oh Jeong-min.

He's a teacher at Bangju High School.

And this guy's address is listed

as apartment 303, Wanseong Apartments Building B.

Don't you find it strange that he lived so close?

And the murder case from last month,

that woman went

to the same gym as him until a few weeks ago.

What a similarity.

Apartment 303, Building B?

Do you have a picture of him?

You're wasting your time.

She won't come out. She's famous for being a recluse.

She even has someone else throw out her trash.

Apartment 303, that bastard.

So he knew both murder victims.

Too much to be a coincidence, right?

Isn't it?

And we can't ignore such a coincidence.

Hello?

Okay.

Go on without me.

I have to stop somewhere first.

What?

FATHER

Are you Mr. Han Ho-san's guardian?

One of our new caregivers just stepped out for a moment when he disappeared.

We are currently searching every corner of our facility.

You must be in shock, but if you could just wait...

Yeah

Maybe it's...

- Sir! - Why is he up there?

It's dangerous up there! Get down!

Quick! Catch him!

Get down from there now!

BUILDING B

What is all this?

DONG-SIK

Yeah, I'm coming.

Ji-uk, this place is weird.

What's weird?

Are you there?

What's weird?

DONG-SIK

Hello?

Dong-sik?

Dong-sik!

DONG-SIK

There's only one left now.

Mom...

Hey.

Jeong-min...

Are you okay?

What are you doing here?

Why...

This is the path to salvation for us all.

Stop it.

You're that recluse from downstairs.

So you're going to stab me with this?

Go ahead.

Why are you shaking so much?

Go on and stab me.

You can't do it?

It is time for salvation.

What bullshit.

Where are my glasses?

Where are my fucking glasses?

Please get up! We have to go!

Oh, no. It's okay.

- Where are my fucking glasses! - Try to get up. Come on.

- Where are they? - Get up. Come on.

Stop!

Let go of me!

What is all this?

Let go of me!

Hey.

I'll be at peace once you're gone.

Die.

Die...

The line is disappearing.

The line is disappearing.

Was he seeing

the S-lines like me?

How?

The glasses?

Are you sure you don't want to go to the hospital?

The man who died...

Who was he?

I'll tell you later.

You have to stop by the station anyway.

Uncle.

What's going on?

Why aren't you answering your phone?

What's with the sunglasses in the middle of the night?

Do you two know each other?

What?

Don't come in if you're not going to give me money.

Do I look like your ATM or something?

Is something going on at school?

Say something.

Will talking about it change anything?

If there's a problem, we have to solve it.

Solve it?

How are you going to solve it?

What are you going to solve?

Are you going to pretend to be my guardian and come to school with me?

You'll just do that for a little bit before you disappear again.

As if you ever cared about me. It's bullshit.

Bullshit?

You little brat...

Forget it.

But...

why was Hyeon-heup

standing outside her building?

How do you know her?

Same middle school.

Her mother killed her father and ran away when she was a kid.

You didn't know?

Thank you.

For the first time, I realized there's a chance

that my ability to see S-lines can help save people.

If that's true,

what should I do now?

I CAN SEE THE SAME WORLD AS YOU.

COME TO BANGJU HIGH SCHOOL.

THE GIRL IN SUNGLASSES

Kids, be careful. Don't get hurt.

We have a new student joining our class today.

Her name is Shin Hyeon-heup.

You can see something with this, can't you?

Red lines.

You can see them, too?

So, why are you still looking at this?

We already caught the culprit.

Something's off.

What?

I just don't understand why he killed them.

Are you going to keep those glasses?

Of course.

Have you lost your mind?

It's your turn to be embarrassed now.

Why would I be embarrassed?

Seon-a.

Even so, violence is not the answer.

I'm going to kill her.
