I said, get in.

Kang Seon-a, get in.

I told you I'm not getting in!

Seon-a

Ugh, that temper of hers.

MATCHMAKING FOR THE FOREVER ALONE

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

No. Some things should not be seen at all.

I've seen these lines ever since I was born.

POLITICIAN'S SEXUAL ASSAULT EXPOSED - I've seen these lines ever since I was born.

POLITICIAN'S SEXUAL ASSAULT EXPOSED - Could we just get a statement? Is it true?

TOP STAR INTERVIEW - Not at all.

TOP STAR INTERVIEW - She's special to me, but we're just manager and actor.

As I grew up, I naturally found out

what those lines meant.

What did you write?

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

DAD ME MOM AUNT

And also a child who made her mom go insane and who killed her dad.

The red lines that were always there,

slowly began to take meaning.

The moment I realized

that seeing 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 the god was playing with me...

and one day, I became completely alone.

I made a decision then.

If I have no choice but to live,

I needed to find out why these red lines existed,

who made them,

who else is watching them besides me,

and how I can get rid of them.

Hello? Anyone home?

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

I was going to give out rice cakes to the neighbours,

but people don't really eat them nowadays, right?

So I bought some fruit, instead.

Do you like fruit?

I never used to eat fruit when I was younger,

but now I can never have enough as an adult.

I'll leave it out here.

Make sure to eat them before they go bad.

BANGJU POLICE STATION

Damn it.

Hey. I'm sorry.

What?

Never mind. Later.

Don't tell me you left another scratch on my car.

What's the occasion today?

Why are you here at this hour?

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

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 royalty nowadays.

So damn royal.

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

Then, what happens when you get married?

- "Married?" - "Married?"

You will come to my wedding, right?

Why would I go to your wedding?

Because we're work colleagues?

What?

Nothing. Just something came up in my mind.

I thought you were a sex addict.

Isn't it too late for you to be picky?

My bad.

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

Why the all they far off

Hey, hand it to me.

Come here.

So I told you not to act up, didn't I?

Jackass.

Seon-a, are you okay?

Does it hurt?

Stand her up.

Seon-a.

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

Then why would you ever report me?

It was you, wasn't it?

Grab her.

My goodness. Seon-a.

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

Get up.

Get up! Damn it.

Hey.

I heard that your uncle is a cop.

It's obivous, right?

And why are you ignoring my calls and texts?

She's so damn heavy.

Did you laugh at me?

If you ever report me again,

I'll actually push you off here.

- Oh, hey. - Hey.

Victim?

She's a 29-year-old woman living alone.

She worked as a manager at a nearby cafe.

Family?

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

Lover?

Nothing confirmed yet. I'll look into it.

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

The body is clean.

It almost looks like a set for a play.

Oh?

This place is good.

Is it famous?

No.

It's a local spot.

Check it.

Yes, sir.

Detective Han.

We received a statement from the first floor neighbor earlier.

They saw a man with a helmet on

headed toward this woman's place late last night.

Helmet?

They said he looked like a deliveryman.

But I just can't figure out

what this punk's goal was.

The money was untouched.

There were no signs of sexual assault.

She doesn't seem like the type people would have grudges against.

Maybe he's just a psychopath?

Does such a psychopath exist?

How'd it go with the restaurant?

We confirmed she does order from there frequently,

but she didn't place an order that day.

And what about her love life?

Did you look into it?

They say she did have one,

but apparently, it ended about a year ago.

Should we look for him?

I JUST ORDERED A BIT TOO MUCH

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

in Sinu-dong with signs of a strangling this afternoon.

The police have reported signs of forced entry

and have started 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 the people with just one, either.

Especially if that person is

trying to eavesdrop anything at a murder scene.

No, I didn't hear anything strange.

Nowadays, deliveries are made on motorcycles day and night.

Even if you see one roaming, you just assume someone has ordered food.

112. What's your emergency?

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

Hello?

Today's topic is equilibriums in ecosystems.

Let's say a grey wolf starts eating up the livestock in a town.

The residents become mad at the wolf

and ask for permission to hunt the wolf.

Then, what do you think happens?

The wolf will begin to hide its tracks.

So you're just not going to show up?

- What the? - What is that?

- What could this be? - Open it.

Clothes?

Jeez, you scared me.

Why didn't you go to school?

Uncle.

Can I have some money?

You can take this for now.

I'll get you some more tomorrow.

How much more can you get me?

Hey, why is your face like this?

Are you getting beaten up out there?

Why do you care?

How much more can you...

Why do you need money?

- Ji-uk. - Yeah. What?

Listen. Someone made a report yesterday

mentioning a man wearing a helmet.

But the possibility of the suspect being a deliveryman was never disclosed.

Do you have 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 Detective Han Ji-uk from Bangju Police Station.

Is anyone home?

Wow...

I've never seen someone

with so many S lines this up close before.

Hello.

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

She's famous for being a recluse.

She even has someone throw her garbage out for her.

I just need a moment of your time.

You made a police report yesterday, didn't you?

Can you just tell me what you witnessed?

It could serve as crucial evidence

in a murder case that happened in the vicinity.

A teenager?

Are your parents home?

It was done accidentally.

I'm sorry?

I called 112 by accident.

Can you give me more details about that situation?

I saw a man with a helmet on walk into the building across from me

and I thought the woman was in danger.

Woman?

Your next-door neighbor.

The woman who moved into Unit 204.

There's just been a lot of incidents recently...

But,

it was her boyfriend.

But,

aren't you a teenager?

Shouldn't you be in school?

What the hell's wrong with the kids nowadays?

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.

ing bitch...

Hurry up.

What's wrong with you?

We just keep going, yeah?

- That's really amazing. - I know, right?

- Isn't it so freaking nice? - How much was it?

I didn't buy it this time.

Did your mom buy it? Or was it your dad?

Don't be an ass.

They passed away.

Ji-uk.

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

His name is Oh Jeong-min.

He's a teacher at Bangju High School.

And his guy's home address is listed

as Unit 303, Wanseong Apartments Building B.

Don't you think it's strange he lived so nearby?

And the murder case from last month,

that woman had been going

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

What a similarity.

Unit 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 throw her garbage out for her.

Unit 303, that bastard.

So he was acquainted with both murder victims.

Too much to be a coincidence, right?

Right?

And we can't just ignore such a coincidence.

Hello?

Okay.

Go on ahead without me.

I need to stop by 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're currently searching every inch of our facilities.

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

Yeah

Maybe that's…

- Sir! - Why is he up there?

It's dangerous up there! Come down!

Hurry! Get him!

Come down from there now!

BUILDING B

What the hell is all this?

DONG-SIK

Yeah, I'm on my way.

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...

Have you been well?

What are you doing here?

Why...

This is the way to salvation for us all.

Stop.

You're that recluse from downstairs.

So you going to stab me with that?

Go ahead.

Why are you shaking so much?

Go ahead and stab me.

You can't do it?

It's time for salvation.

What a crock of shit.

Where are my glasses?

Where are my damn glasses?

Please stand up! We need to go!

Oh, no. It'll be okay.

- Where are my damn glasses! - Try to stand up. Come on.

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

Stop it!

Let go of me!

What is all this?

Let go of me!

Hey.

I'll be set once you're gone.

Die.

Die...

The line is disappearing.

The line is disappearing.

Did he see

the S lines like me?

How?

The glasses?

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

The man that died...

Who was he?

I'll tell you more later.

You need to stop by the station at some point anyway.

Uncle.

What's going on?

Why haven't you been picking up 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 an issue, we need 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 with me to school?

You're just going to do this for a bit before you disappear again.

As if you ever cared for me. This is bullshit.

Bullshit?

Why you little brat...

Forget it.

But...

why was Hyeon-heup

standing outside of her building?

How do you know her?

The same middle school.

Her mom killed her dad and ran away when she was a kid.

You didn't know?

Thank you.

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

my ability to see S lines could help save people.

If that's true,

what should I do now?

I CAN SEE THE SAME WORLD YOU SEE.

COME TO BANGJU HIGH SCHOOL.

THE GIRL WITH THE 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 these on, can't you?

Red lines.

Can you see them, too?

Then, why are you looking at that again?

We already caught the culprit.

Something's sketchy.

What?

I just don't understand why he killed them at all.

Are you going to hold onto those glasses?

Of course.

Have you lost your mind?

It's time for you to be embarrassed now.

Why would I be embarrassed?

Seon-a.

Even so, violence isn't the answer.

I'm going to kill her.
