EPISODE 13
TEENAGE BRAIN VS PSYCHOPATHIC BRAIN

Eun-h*!

I can't afford to be in love anyway.

It was hard to believe from the start.

Still, it gave me the chance
to drink with you, Dr. Brain.

It's not bad.

Right? It's nice to drink together.

-It's not bad.
-Right?

That's right. I don't need love.

You're the only one I need, Dr. Brain.

I'm saying the food isn't bad.

What?

Right. Of course.

Sir, can you give us some more of this?

Coming right up.

It's nice. I like it.

Hey, you.

Dr. Psycho.

So you're a psychopath?

Do you just want to k*ll people?

Listen. You're drunk.

Yes, I'm drunk.

And while I'm drunk,
I want to ask for a favor.

Could you please take a look at my kid?

I think...

my kid is a psychopath.

What is he on about?

I have a son.

He always gets mad
without rhyme or reason.

He locks himself in his room
and refuses to talk.

I don't know what he does all night,
but he sleeps all day.

I pay so much
for his after-school lessons.

I put up with my boss all day

just so I can afford lessons for my kid.

But he doesn't care one bit.

He's incapable of empathy.

Doesn't that make him a psychopath?

I don't even expect empathy.

When I look at my daughter,

I think an alien
might've taken over her body.

I know what you mean.

There are moments
when I question if my son is really mine,

but he looks just like his dad.

Dr. Shin.

He must have a psychopathic brain, right?

No.

He does not have a psychopathic brain.

What he has is a teenage brain.

It's not only the body

but also the brain that matures
during the teenage years.

But you see, our brain...

typically matures from back to front.

That's why during the teenage years,

the frontal lobe is less developed
than the back regions.

The frontal lobe
controls rational thinking and judgment

in addition to regulating
behavior and emotions.

Thus when you're a teen,

your frontal lobe is still immature,

which means you can't control
your impulses or emotions.

This makes you impulsive,

prone to excitement or despair,

and unable to grasp
the big picture of a situation.

-I see.
-I see.

So the conflicts between you
and your teenage children

are really no one's fault.

When you don't understand
your child's behavior, tell yourself this.

"My kid's brain must be in disarray

because the frontal lobe
is still under reconstruction."

"That's why my kid
is behaving so ridiculously."

If you think that way,

you'd have fewer issues with them.

He's right.

Yes, you're absolutely right.

It's so true!

Then...

I have one more question.

How do I

communicate with my children?

When you're talking to teenagers,

you should speak clearly,
repeatedly, and slowly.

But I get so angry
even just by looking at him!

How can I speak clearly and slowly to him?

Hey!

That's enough!

Jeez. We should drink somewhere else.

They turned that into a special lecture.

Let's go, Dr. Brain.

No, thanks.

Come on.
We barely drank because of your lecture.

I want another drink.

Do you know why that is?

It's because the alcohol
has altered your brain.

Alcohol induces the release of dopamine
and lifts your mood.

It also acts on the amygdala

and helps you forget
your worries and anxiety.

But if you keep drinking like that,

the brain develops a tolerance
and becomes unable to function without it.

In the end...

-In the end?
-You become an alcoholic.

You'll become a drunkard.

Jeez, stop talking about the brain.

I'll give you my full attention,
so let's just have one more drink.

Where shall we go? Somewhere quiet?

That's right!

Let's go to my place!

No, thanks.

Just consider it an honor
that I spent this much time with you.

Hey, you could freeze to death.

Get up.

Get up.

Are you not going to get up?

Fine, I'm leaving.

Oh dear!

My friend is ditching me.

He really is a psychopath.

He's abandoning his friend.

-Goodness.
-He should take his friend home.

He's a jerk.

He's a psychopath, after all.

Come on. He hasn't left yet.

Let's see what he does.

The worst that could happen to me
is freezing to death here.

We're all going to die anyway.

-Detective Geum.
-Oh boy.

Let's go.

I'll take you home.

Oh dear.

See?

He may have a psychopathic brain,

but he's not a total weirdo.

You're right. He cares about his friend.

Hey, friend. Where do you live?

Me?

Over there.

It's that way.

Let's go!

Off we go!

I should've just ditched you.

You said we were almost there.
Where is it?

Over there.

What's wrong with you?
Speak clearly, will you?

Over there.

That building over there.
On the third floor.

What? You're not drunk?

I am.

But I'm not that drunk.

Do you think you can handle
the consequences of your nonsense?

I can, but I don't think
your bladder can handle it.

You said you had to pee. Use my bathroom.

You don't want to pee your pants
on your way home.

Hey, look.

We're almost there.
It's just right there on the third floor.

Come in, Dr. Brain.

It's okay. Come on in.

Come in.

Here we are.

Come on in. The bathroom is right here.

I'm here to use the bathroom.

I didn't want to come here.

I heard you. My goodness.

Yi-na!

Dad's home.

My friend is here too.
Come out and say hi.

Are you asleep?

The handsome neuroscientist
you like is here.

Come out and say hello.

At least say hello, Yi-na.

What?

No...

What is going on? Yi-na.

That's odd.

Just leave her alone.

She should come out
and say hello to my guest.

Did you forget my lecture from earlier?

She's a teenager.

Jeez.

Fine.

My dear daughter's frontal lobe
is under reconstruction.

It's only natural for her.

-All right then. I'm off.
-Wait!

Sit down for a moment.

You can't leave like this.

You can have that last drink by yourself.

Then have some water.

You emptied your bladder.

Now it's time to fill it up again.

What?

Where did everything go?

What?

The cups are all gone.

A burglar wouldn't have stolen cups.

What?

Dad...

I'm in trouble.

You...

Yi-na!

What happened?

What should I do?

He's alive.

Yi-na.

It looks like a brain hemorrhage
caused by an external injury.

We're the paramedics of Geumpyeong EMS.

We came in response to an emergency call.

I called them.

Are you all right?

Can you stay with Yi-na
until her mom gets here?

Don't worry. Go ahead.

What happened?

What happened to him?

The thing is...

I think I did that to him.

KOREA NATIONAL UNIVERSITY HOSPITAL

Are you Eun-h*'s mother?

-Yes.
-Hello.

I'm Geum Yi-na's father.

She was with Eun-h* tonight.

Eun-h* is undergoing emergency surgery
to stop a brain hemorrhage.

What do you mean by a brain hemorrhage?

The doctor thinks
he hit his head somewhere.

Good heavens.

What do you mean he hit his head?
Did someone push him?

They'll have to investigate.

The police will round up the kids
that were with him

and launch an investigation right away.

Mr. Geum,
I heard you are a police officer.

That's right.

Please look into it thoroughly.

Whoever did this
must be brought to justice.

Of course.

Hello.

My goodness.

Parenthood is full of twists, isn't it?

Did you find bloodstains
on the edge of the vanity table?

Yes, that's where he hit his head.

Was he pushed
or did he stumble by himself?

We won't know until we investigate.

Where's your daughter?

She was in shock,

so her mother took her for a walk.

Please bring her in tomorrow
so she can give her statement.

If you'll excuse me.

SEOBU POLICE STATION

We're ready for you.

I thought you couldn't be on the case
because you're family.

I'm not investigating the case.

But I can still go in with her
as her guardian.

Let's go.

Hey, did you have a nice day off?

Yes, sir.

I saw Detective Geum's daughter here.

What's going on?

How's the boy doing?

The surgery went well
but he hasn't woken up yet.

The questioning will begin soon.

I should go and watch,
in case I can be of help.

I'll go with him.

Go ahead.

Jeong Eun-h*, Kim Hyeon-jun,

Jeong Min-gi, Lee Jeong-h*,

Seo Gyeong-il, An Hye-yeong,
and Kim Min-ji.

Seven in total.

Were they the kids at your house that day?

Yes.

Are you all close?

No.

We're not that close,

but they've been wanting
to hang out with me lately.

I didn't want to, but I had no choice

because they can be scary.

Why were they at your house
when you weren't close?

I didn't invite them over.

Eun-h* and I had agreed to meet up.

Suddenly, someone rang the doorbell,
and I saw that it was Eun-h*.

So I opened the door and...

This is a surprise.
I thought we were meeting out...

Hey, Yi-na.

Nice place.

-This place is nice.
-It's nice and cozy.

-Nice.
-This is nice, Yi-na.

-Hi, there.
-Hi.

They all came with Eun-h*.

It seemed like they'd threatened Eun-h*
into bringing them.

They said they wouldn't stay long,

so I reluctantly let them in.

But then they started
taking drinks out of their bags.

This is for you.

Let's drink it all.

This looks great.

It's fine. There's no need to be scared.

-That's right.
-What a treat.

Yi-na, we got you something extra special.

Right, Eun-h*?

They said they'd drink and leave
before my dad got home.

I told them not to drink too much,

but they kept drinking
and refused to leave.

-Drink.
-Drink.

-Drink.
-Drink.

-Drink.
-Drink.

-Drink.
-Drink.

-Drink.
-Drink.

-Drink.
-Drink.

-Drink.
-Drink.

They said they'd leave
if I drank just one glass.

Great job.

So I reluctantly had a drink.

But I don't remember anything after that.

When I came to,
I saw Eun-h* collapsed on the floor.

So I called an ambulance and waited.

That's when my dad came home.

You should've called me first
in a situation like that.

And why did you lock your door?

Detective Geum.

Sorry about that. It just came out.

A teenager's brain is as messy and chaotic
as a construction site.

They might not know how to act
in dangerous situations.

What do you think?

Do you think Yi-na was involved?

Yi-na doesn't seem to be lying.

But we should hear
from the other kids too.

We just went over to her house to drink
because her dad wasn't there.

Yi-na and Eun-h* drank as well.

They got drunk and started arguing,
so we just left.

They got drunk and started arguing,

so we just left.

They started arguing, so we just left.

Eun-h* probably fell to the ground

when Yi-na pushed him away
after came on to her.

How did you know
that Eun-h* fell to the ground?

I never mentioned that.

Well...

It's just my theory.

They're all blatantly lying.

Yes, they seem to have agreed on a story.

What will happen to Yi-na?

No evidence points to Yi-na
hurting the boy.

And the lies told by
these cognitively-lacking fools

won't hold up for long.

So don't worry too much.

Yi-na and Eun-h* started arguing,

and the boys were all drunk
and talking nonsense.

I was so annoyed
that I left early with Min-ji.

Around what time?

Around 9:00 p.m.

But then I got a text from Yi-na
on my way home.

She confessed to me that she had done it.

Can I see the text?

Sure.

Here.

Where are you?

I'm on my way home. Are you okay?

You two got drunk and fought like crazy.

GEUM YI-NA

I think I k*lled Eun-h*.

He kept coming on to me,
so I pushed him away.

But he hit his head

and now he won't get up.

There's no way...

Did Yi-na say anything about this text?

I need to find out for myself.

No! I never sent that text!

We don't even text each other!

Look.

She said it wasn't her.

You can do that forensic thing to check.

Can you hand in your phone as evidence?

Take it. Are you happy now?

AN HYE-YEONG

Don't worry. Don't cry.

It's okay.

It'll be okay.

I trust you, Yi-na.

It's okay.

I'm here for you.

Let's see. 9:12 p.m.

The forensic analysis shows

the messages were sent.

I THINK I k*lled EUN-h*

HE KEPT COMING ON TO ME
SO I PUSHED HIM AWAY

BUT HE HIT HIS HEAD
AND NOW HE WON'T GET UP

I don't know!
I told you I didn't send that!

-Yi-na!
-Forget it!

You won't believe me anyway!

Let go! I don't need you!

Yi-na!

It seems your daughter left the chatroom
after sending those messages.

That's why there's no sign of the chat
on her phone.

Why do you think she left the chatroom?

Wouldn't it be because she felt guilty?

She's not the type of kid who lies.

Parents are often the last
to see their kids' flaws.

We have enough evidence
to name her a suspect.

If you'll excuse me.

My daughter

will be a suspect?

Hello, Prosecutor Han.

Really?

Thanks. I owe you dinner.

It means a lot to me.

Yes. Tell him I'll be there right away.

I'll see you later.

JANGWON CORRECTIONAL FACILITY

Hello. Take a seat.

You got here real quick.

Of course I did.

When I heard you accepted my deal,

I rushed over with joy.

Is it true?

Will they reduce my sentence
if I donate my brain?

I went to middle school and university
with the prosecutor on your case,

and we're very close.

I'll talk to her for you.
I'll also write a petition in your favor.

I'll even get a petition
from the director of the lab

that will receive your brain.

He's like family to me.

You must know

that's good enough

to reduce your sentence.

Bring the donation form.

Hurry before I change my mind.

A petition?

I don't want someone like him
to get a commutation.

Don't worry.

He won't get one.

What did you do?

This punk took his girlfriend's life
just because she broke up with him.

Who cares if I lied if it gives him
a chance to make up for it?

He should be grateful.

The way you stop at nothing
to get your way...

I see.

It makes me seem psychopathic, doesn't it?

If you know that, don't do it.

If you write the petition,

I'll stop visiting Dr. Hwang.

Why?

You never do as I say.

Of course it won't be
because you told me not to.

I visited Dr. Hwang
because I wanted him to donate his brain.

I won't have to see him
if I can get Kang In-h*'s brain.

So,

I just need you to write the petition.

DIRECTOR'S OFFICE

PETITION

Why did you lie?

Why did you say I sent those texts?

What are you saying, you *****?

You did send them.

No, I didn't.

Hand over your phone to the police.

I chose not to submit it for your sake.

I have photos of you
drunk out of your mind.

Are you okay with
your dad's colleagues seeing that?

I'll give them my phone
if you're okay with that.

Your dad will be so humiliated.

What do you think?

There's more where this came from.

I think she's crying.

I think it's because
you don't believe her.

It's not that I don't believe her.

I just want her to think harder.

There must be an explanation
for that evidence.

She said she can't remember.
She was drunk.

Why did she drink in the first place?

You shouldn't have been
out drinking yourself!

If you hadn't,
you would have been at home,

and this wouldn't have happened!

How would I have known this would happen?

It's my fault.

This is all my fault.

I should've been here with her.

My poor Yi-na.

I'm sorry.

I'm so sorry.

DR. SHIN HA-RU

DR. SHIN HA-RU

Hello, Detective Geum.

It's so weird.

You're the only person
I can call in this situation.

I'd been wondering how it was going.

So what's happening?

What do you think?

I want to believe my daughter,

but there's all this evidence.

I don't know what to do.
All I can do is sigh.

What would you do
if you were me, Dr. Brain?

If I were you,

I would carefully examine
the forensic findings again.

Isn't that what detectives do?

What?

Are you afraid it might confirm
that Yi-na actually did it?

How did you know?

You really can read me like a book.

You're right.

I think that's why
I feel so weighed down by this.

I suppose it's natural for you
to feel that way as a parent,

although I can't quite empathize.

Anyway, the second questioning
will take place tomorrow, right?

I have to stop by somewhere on the way,

so please have the forensic results
and an updated status report ready.

See you then.

At least he cares.

Yes.

I'm a father.

No matter what truth I find out,

I will accept it.

FORENSIC ANALYSIS OF CALL LOG

She called an ambulance

at 9:30 p.m.

The message was sent at 9:12 p.m.

What happened during the 18 minutes?

I sobered up and called an ambulance

as soon as I saw Eun-h*.

An Hye-yeong.

Kim Min-ji.

WOMEN AND JUVENILE AFFAIRS DIVISION

Hello.

Detective Geum?

What are you doing here?

-A setup?
-A setup?

Take a look.

Yi-na sent the message at 9:12 p.m.

Then she called an ambulance at 9:30 p.m.

Thirty minutes later,
she frantically called her friends.

I think she was
trying to find out what happened.

But none of her friends picked up.

Yi-na said she called an ambulance
as soon as she came to.

I think it's plausible.

So Yi-na was still unconscious
when the message was sent.

How did they know her passcode?

They used her fingerprint.

Hey, find her phone.

Yes, find it.

-Did you find it?
-Yes, it's here.

Unlock it with her fingerprint.

I unlocked it!

I sent it.

It's possible they sent it.

What time did those boys leave?

Based on the footage from
the security camera in the alley,

they left at around 9:20 p.m.

It means they were with Yi-na
when that message was sent.

There's definitely a chance
that they set this up.

If they exit the chatroom
after sending the message,

the chatroom would disappear,

and Yi-na wouldn't know
anything was sent from her phone.

That's why she confidently
demanded a forensic analysis.

That's what I'm saying.

I considered reaching out to
the Women and Juvenile Affairs Division,

but I didn't want to seem like
I was meddling in the investigation.

Right. Since you're her dad,
they could get the wrong idea.

Then...

I'll go and talk to them.

Yes, help him out.

Captain Seol.

Thank you.

They did sound like
they agreed on a story,

so I did have my suspicions.

Before we designate Yi-na as a suspect,

we should go through their phones too,
don't you think?

Yes, we should.

Tell Detective Geum not to worry too much.

The truth is bound to come out.

Okay.

How have you been, Dr. Hwang?

What's with you today?

I'm surprised you answered my call.

I tried calling a few times,
but you never picked up.

I suddenly wanted to hear your voice.

Did something good happen?
You sound happy.

Yes, I came to see Kang In-h*

and have him sign
the donation consent form.

Is that so?

Will Kang In-h* really
be able to sign the form?

He gladly accepted my offer.

I'm sure he'll donate.

It's time for me to meet
the psychopathic brain that I need.

I have to go.

What's taking him so long?

Damn it.

Emergency situation
at Cell 216, Building B!

It's an emergency! Hurry!

Go!

You'll have to leave.

I'm afraid we have to cancel
your special visit.

-What happened?
-Kang In-h* is dead.

-Please leave.
-Wait.

-Did he take his own life?
-Yes.

He was fine this morning.

But before your visit, he suddenly...

Is that so?

Will Kang In-h* really
be able to sign the form?

You.

What did you do?

Oh my.

You sound very angry.

Why?

Is it because your new toy is broken?

This is what you get for ignoring me.

I find that worse than being disrespected.

And I absolutely despise
those who beg for attention.

No, that's not true.

You're not actually ignoring me.

You're merely trying to ignore me

as a way to avoid pain.

If you have the courage to face pain,

come and see me.

I'm guessing

that you will need my brain again.

I'll be seeing you soon.

If you have the courage to face pain,

come and see me.

It was just an ordinary car accident.

That man is plotting
to use your incomplete memory

to shake you up.

Is Yi-na's father here?

You're Eun-h*'s mother.

I heard it was Yi-na who hurt my son.

Nothing has been proven yet,
but I apologize nevertheless.

Ma'am, it's still
an ongoing investigation.

Are you taking his side
because he's a fellow officer?

I can't trust this team
with the investigation.

There seems to be a misunderstanding.

Our team isn't investigating the case.

It's being investigated by
the Women and Juvenile Affairs Division.

I can't trust this entire station.

To ensure a fair investigation,

please have a different station
investigate the case.

If my request isn't met,

I will take action.

Of course, ma'am.

I understand why you would want that.

Please don't worry.

The case will be transferred
to another station

to ensure a fair investigation.

I was so consumed with worry
for my own child

that I didn't stop
to consider how you'd feel.

When a family member is involved,

the case can be transferred
to another station.

The outcome won't be affected
by which station takes the case,

but Yi-na will experience more pressure
if it's transferred out.

So today is the last day
she'll be investigated at this station.

That's right.

Then we need to
find the evidence we need today.

Who's up first?

What time was it when you came to?

Around 9:30 p.m.

After I came to,
I immediately called for an ambulance.

You made the call at 9:30 p.m.,

but you texted Hye-yeong at 9:12 p.m.

Are you saying
you weren't awake at the time?

If you don't want to be humiliated,

choose wisely.

Yi-na.

I'll ask again.

That text...

Did you send it?

The thing is...

Yi-na is highly agitated.

You said you didn't text her.

That's why you demanded
a forensic analysis on your phone.

Yi-na.

Answer the question.

I think I sent it.

But you said you came to
at around 9:30 p.m.

How could you have texted her
at 9:12 p.m.?

I don't know.

That's absurd.
Then why was she lying all that time?

It's possible
the statement she just gave is false.

Her attitude has visibly shifted.

It appears that something happened.

It's all right.

Let's go home. It's okay.

It's likely that Yi-na is lying

about sending that chat.

Even I could tell that.

There must be a reason
she's suddenly acting like that.

Why won't she say anything?

How can I help her
when she won't tell me anything?

I'm sure there's a reason
for that as well.

According to the security footage
from the alley by Yi-na's place,

you left her place at 9:18 p.m.

So?

Get to the point.

Yi-na texted Hye-yeong at 9:12 p.m.

Does that mean

you were with her at the time?

Yes.

Then did you see Yi-na
texting on her phone?

No.

But you said you were with her.

Yi-na was in her room

and I was taking a dump.

Me?

I was there smelling his poop.

That's gross!

Quiet!

Aren't you the ones

who sent the message?

The circumstances give me reasonable doubt
that you sent the text.

Do you have proof?

Bring me the proof and then we'll talk,

you hag.

She has such a rough job
considering her old age.

Can you turn in your phones?

I don't want to.

You don't have to turn yours in.

It won't be an issue.

I don't want to.

I don't have a phone, you see.

Do I have to turn mine in?

It's not that I'm trying to be difficult.

There's just a lot of porn on it.

I can't hand over mine anyway,
because my teacher took it away.

If you're mad about it,

take it from my teacher.

Is that so?

I could issue a warrant
and take them by force.

I'm so scared.

-Gosh.
-Is that so?

Then take them by force.

But if you do,

I'll k*ll myself.

If I die, it'll be on you.

What are you doing? Stop!

-Look.
-He's nuts.

That's hilarious.

Let go!

Let go of me!

Let go!

Let go of me!

What a joke.

Let go of me!

I feel drained each time
I go through something like that.

I'm so scared.

What if he really commits suicide?

I don't want to deal with him anymore.

I'm turning the case over
to the prosecution.

With Yi-na as the suspect?

All the evidence and statements
point to her.

She even confessed.

There must be a reason
she suddenly changed her story.

Captain Seol,

are you interfering with my investigation?

Of course not.

I'm sorry.

I really thought you were going
to crack your skull open.

I should have bled a little.

Does it hurt?

Yeah. Do you even have to ask?

Hey,

it's that psychopath scientist.

What is it?

Do you have something to say?

There's one thing you should know.

I'm in a really bad mood today.

I lost something incredibly valuable.

What's he saying?

So you'd better think carefully

before answering my question.

Are you blackmailing Yi-na?

No.

Why would we blackmail her?

We're not bad kids.

We just showed her a photo.

Aren't you curious
what kind of photo it is?

Give me a call if you want to see it,
Mr. Psycho.

He's so scary.
Must be because he's a psychopath.

I guess he is a bit scary.

I heard he got kicked out of the lab
for having a nasty temper.

Makes sense.

I heard he stole a corpse
to dig out the brain.

That's pretty cool.

This is terrible.

Will the prosecutors send her
to a juvenile court?

If the boy doesn't wake up,

she'll be charged with
as*ault causing grievous bodily harm.

She might be tried in an adult court.

That'd be really hard on her.

I have to go and ask her

why she changed her statement.

I'll ask her. Where is she?

At home.

It's fine. I should ask her.

Some things are hard to tell a parent.

He's right. She's at a very sensitive age.

Yes. He should ask instead.

I'm counting on you, Dr. Brain.

If things go wrong,
I might go off the rails.

I might bring in the kid and t*rture him
until he confesses.

What? Am I being too harsh?

My daughter's life is at stake.

No.

Let me do the torturing for you.

In a very brutal manner.

Yi-na.

I'll help you.

But you have to be honest.

Are they

threatening you with photos?

Why are you crying?

They're the ones at fault.

You didn't do anything wrong.

They're the ones at fault.

You did nothing wrong.

They're the ones at fault.

It's not your fault.

Okay?

Good.

It's not your fault, so don't cry.

Of course, you might want to cry
because you feel wronged.

But you still shouldn't cry.

If you do, they'll think
they can walk all over you.

Okay.

You have to be confident.

Tell them, "This is what they did to me."

You have to speak up.

Only then can we help.

Now,

can you tell me what happened?

I didn't send that message.

When I told her to hand in
her phone to the police,

she threatened me with a photo.

She said she took weird photos that day.

Did you see them?

I saw one.

But she said there were lots more.

She asked if I'd be okay
with my dad's friends seeing them

and said if I didn't want that,
I should say I was responsible.

She said she'd leak the photos
if I didn't.

I had been trying to avoid them,

but I ran into them a few days ago.

And...



I have 20 photos, so that's 1,000,000 won.

I don't have that kind of money.

You don't?

Then we'll go out
and get the money ourselves.

I'll sell them

for 500 won per photo.

Let's upload them now.

Let's do it right now.

I don't know what to do.

I'll sort it all out for you.

Call the punk.

This is hilarious.

Hey, it's Geum Yi-na.

GEUM YI-NA

I don't have money,
but I have something else to give you.

Meet me here by yourself.

I guess she's learned how to play along.

Hey, I have to go.

Geum Yi-na!

Hey, Yi-na!

What is this? You said you'd be here.

Hey, Yi-na!

Is that you, Yi-na?

What is this?

I'm here to teach your brain a lesson.

I would normally blame your little stunt
on your underdeveloped frontal lobe,

but this seems a bit extreme.

You're like a bus with no brakes.

Before you ruin someone else's life,

I thought I'd put
the brakes on you myself.

Your brain needs to be taught
once and for all,

that if you keep up this behavior,

you'll have to
kiss your sweet life goodbye.

What are you on about,
you damn psychopath?

Let go!

Let go of me, you murderous psychopath!

You can't do anything on your own,

yet you act like you're all that
with a few minions.

It's pathetic.

Kids can be like that at your age.

But you crossed the line.

And you should pay the price.

You murderous psychopath.

What are you doing?

Are you going to k*ll me?

No.

But you'll be wishing

that I k*lled you instead.

This machine is used for
the neuroscientific method of t*rture.

See for yourself.

You'll wish you were dead.

Now, how about

we get started?

I don't want this!

Go away, you *******!

Isn't revenge always sweet?

You can't overcome your rage.

"Doctor and wife
m*rder*d in Pyeongchang-dong"?

You're destined to become a m*rder*r.

Ha-ru, run away!

This case...

Did Dr. Brain catch on?

Why did you lie to me?

What is the truth you know?

If you let me out,

I'll tell you who it is.

The culprit.
