EPISODE 12
EFFECTS OF LOVE AND BREAKUPS ON THE BRAIN

The owner of this brain,

the person with
this psychopathic brain is...

It's me.

Order in the court.

Counsel, have you finished
questioning the witness?

No, we wish to continue.

Are you the author of this book, Dr. Shin?

Yes.

In this book, you say psychopathy
has a definite genetic component,

but that it's greatly affected by

one's childhood environment
and upbringing.

When a child with genes
that inhibit impulse control

grows up in a negative environment,

those genes become expressed,
and this leads to psychopathy.

Do you maintain that stance?

Yes.

Then do you think
Mr. Kang's rough childhood

of growing up with an alcoholic mother

contributed to the expression
of his genes related to psychopathy?

Yes, I think it definitely had an effect.

Dr. Shin,

your family is very wealthy, correct?

Yes.

Then it's possible that
because you grew up in affluence,

your genes related to psychopathy
were not expressed.

It's true that I grew up in affluence.

However,

I lost both of my parents when I was six.

For a child who had everything,

to lose both parents
before his eyes overnight...

Could anything
be more stressful than that?

To this day,
I can't remember the accident.

My brain experienced so much stress
that it erased the memory.

My client worked in poor conditions.

As a prison guard,

he was constantly exposed
to violent criminals.

I too came into frequent contact
with violent criminals

while conducting research on psychopathy.

Their brazen shamelessness
often gave me the urge to k*ll.

Once, I was almost
strangled to death by a m*rder*r.

Having a psychopathic brain

cannot be a reason to k*ll.

I am...

proof of that.

That will be all.

Dr. Shin, you are excused.

Gosh.

What? Are you afraid?

As if.

I knew long ago you were a psychopath.

Then why are you flinching?

I don't really know. I can't help it.

IN SESSION

COURTROOM 417

Kid.

At last, the game has begun.

You were surprised, weren't you?

No. I once yelled at you.

That jerk.

I get that he doesn't like me.
But how could he dump me like this?

You psychopath!

Don't you remember?

Not really.

I get yelled at by a lot of people.

I'm sure you do.

I've also sometimes wondered aloud
if he was a psychopath.

And each time you did, I said to myself,

"How did he know?
He's smarter than I thought."

Anyway, do you think you'll be okay?

Word will have gotten out by now.

If I feared that,
would I have brought it up?

-It's him.
-It's Shin Ha-ru!

-Dr. Shin!
-Doctor!

-Doctor!
-Dr. Shin.

Is it true you just admitted in court
to being a psychopath?

I'm not a psychopath.

I have a brain
with psychopathic tendencies.

Doesn't that mean you can
turn into a psychopath at any time?

There is a possibility.

Does that mean you could
become a m*rder*r at any point?

When people think of a psychopath,

they imagine someone
who goes around k*lling people.

But that's not the case.

Of course, they might be
more likely to do such things,

compared to those without such tendencies.

But the likelihood of committing m*rder
is greater, right?

Are you asking about the probability
that I'll commit m*rder?

Yes.

If I were to ever become a m*rder*r...

I would've become one
when I was fired from the lab.

You all may recall
how publicly I was ousted.

But my advanced metacognitive skills

prevent me from ruining my life
with such foolish behavior.

Therefore,

the probability
that I'll become a m*rder*r

is nonexistent.

Let's see if that's the case.

But the likelihood of committing m*rder
is greater, right?

Are you asking about the probability
that I'll commit m*rder?

Yes.

If I were ever to become a m*rder*r...

Shin Ha-ru.

Jeez.

Do you know
what people are saying about you?

They're saying you're a m*rder*r.

They'll see in time that I'm not.

People only hear what they want to hear.

They don't care
if you're actually a m*rder*r or not.

There's even...

a photo of you in a prison uniform
circulating online.

REVOLTING m*rder*r!
PSYCHOPATH, DEVIL

This is a bit harsh.

I should screenshot this and sue them.

Ha-ru,

people don't know the biological meaning

of having a brain
with psychopathic tendencies

It's a difficult concept to grasp.

They'll just think of you
as a potential m*rder*r!

Well,

isn't that true?

Ha-ru!

It was a joke.
Don't take it too seriously.

Auntie,

I'm confident.

Confident that I can control my brain.

So don't worry.

Hey.

I knew from the moment he threatened

to dissect and chew up your brain.

He totally is a psychopath!

He's not the murderous kind of psychopath
you're imagining.

He just has some tendencies. That's all.

Haven't you noticed anything strange?

It's fun driving a rickety car for once.

Dr. Brain!

Not at all.

He's just a bit quirky.

You're acting weird. You've changed.

Dr. Shin has been gaslighting you,
hasn't he?

Are you serious?

If you're thirsty, just drink this.

Are you low on blood sugar?
Why are you talking nonsense?

Did you ever notice anything strange
while working with Dr. Shin Ha-ru?

Will you keep him on the team
as your consultant?

Well, you see, that's...

Of course he's not here
when I'm in a pickle.

Hey, Dr. Shin!

Chief Kim! Sir!

I barely escaped.

Sir.

You didn't say anything, right?

He's probably already stressed out
by all the rumors.

I didn't say anything.

Of course we should protect
a member of our team.

Think carefully.

With your repulsive mind,
you could've let something slip.

What? Are you talking to me?

Who saved your life?

That's right. You're my lifesaver.

My lifesaver.

Hey, Dr. Brain.

Your ears must be burning
from us bad-mouthing you.

That won't be enough to faze me.

I've had the whole nation
bad-mouthing me before.

Of course you have.
He's on a different level in various ways.

I heard what happened.

So you're like me?

Captain, you're no match for me.

Hey, what did we do to deserve this?

We have to work with two psychopaths.

I have three in my life.
I deserve the most pity.

I'm sorry to interrupt.

Hello, ma'am.

I won't keep you from your work.

I'll go ahead and change the filter.

NEUROSCIENTIFIC INVESTIGATION TEAM

Something's different about her today.

I have a bad feeling about this.

It's all clean now.

Make sure you drink water often.

Water is the best medicine.

I'll leave you to it.

All right. You should get going.

No.

I need to talk to Dr. Shin.

Dr. Shin,

can we talk for a moment in the lounge?

The lounge?

Yes.

All right then.

I'll be off.

What's going on?

What's going on? It's making me anxious.

Don't tell me

she's going to make a move on Dr. Brain.

What is it?
You're making me uncomfortable.

Could you sit here for a moment?

I won't bite.

Please sit by me for a moment.

May I hold your hand for a moment?

Well, as you know,
I have psychopathic tendencies,

so I rarely get flustered.

But you have me flustered.

It's just that there's something odd.

It'll only take a moment.

That's odd.

I don't feel anything.

I just held the hands
of a handsome man like you

and stared right into your eyes,

but I didn't feel anything at all.

Did you use to feel something
just from making eye contact with men?

I used to feel things
even at the sight of a golf ball.

I see.

That's odd, right?

It's not normal, right?

Well, it could be
a symptom of hypersexuality.

That's right.

I was never able to tell anyone.

I always felt as though

there was a storm in my heart.

But then,

strangely enough,

the storm suddenly died down.

Myeong-sae always goes on
about how smart you are.

That's why I'm asking you.

What's wrong with me?

When you say it happened suddenly,

was it after you left the hospital?

-Yes.
-Do you take any medicine?

Anything you stopped taking
in the hospital?

Medicine?

Well, I'm very healthy.

The only drugs I take

are my weight loss pills.

Weight loss pills?

Do you have them with you?

One moment.

Yes. Here.

I got these
from a traditional medicine clinic I know.

They work like magic.

I had gained a lot of weight
while pregnant with Yi-na.

But thanks to those pills,
I was able to regain my figure.

When something works like magic,
there's usually a reason.

What did she say?

Did she say something weird?

She told me something very interesting.

Do you know anyone
at the Ministry of Food and Drug Safety?

The Ministry of Food and Drug Safety?

Well, I'm not sure. Why?

Track someone down at all costs

and ask them to run a drug analysis.

It's the weight loss pills
your ex-wife used to take.

They could be the reason
she cheated on you.

Really?

If you'll excuse me.

You haven't forgotten
about tomorrow, have you?

Of course I remember.
I've been looking forward to it.

My gosh, I'm blushing.

I came way too early.

Do you hear that?

Yes.

It feels great.

The crunching of the leaves.

It's the sound I love.

I consider it
my own healing ASMR of sorts.

I would come here after being scolded
by the subsection chief

or when I was down.

I dreamed of going on walks like this
with my boyfriend one day.

That's why I brought you here.

I'm glad you did.

I also have something
I dreamed of doing with my girlfriend.

Going on walks

while holding hands.

What other things did you want to do?

There are a lot.

What are they?

Just tell me.
We'll do everything you want.

-Really?
-Of course.

I'll do everything in my ability.

This is something I've wanted to do.

INSTANT NOODLES

When I'd come here by myself,

it felt too pathetic
to eat this by myself.

Whenever I walked by this place,

I dreamed of eating here
with my boyfriend one day.

Here.

This is the best way
to enjoy instant noodles.

Cheers.

I want to take a photo like this,

but it doesn't seem like
the leaves will fall any time soon.

I have an idea.

Nice.

Check out the heart.

What else did you want to do?

I wanted to go camping.

There's a camping site over there.

That's something I have to study up on.

I hear it's hard
if you don't know how to go about it.

Then let's both study up on it

and come back
before all the foliage is gone.

Sounds good.

A camping trip
before all the foliage is gone.

Your request has been submitted.

Dad, is that funny to you?

Yes, it is!

Look. See that leaf floating away?

What the...

Even at my age,

I'm laughing at
the mere sight of leaves floating by.

What's wrong with you?

I just love the fall foliage.

I love autumn leaves.

I have a request.

Please let me know
if there's anything you want.

I hear women want men
to figure it out themselves,

but men don't know unless they're told.

There's only one thing I want.

To not break up.

My gosh.

She's making me blush.

All she wants is to not break up.

That's how I feel.

Dad's acting strange.

I think he's lost his mind.

You shouldn't
talk about your dad that way.

What?

What's going on?

I repent.

Under the sway of unwanted impulses,

I fooled around

with one man after another.

However, there has never been a moment

where I did not care
about Yi-na and her dad.

If I'm given a second chance,

I will devote my life to my family.

My mom's acting strange as well.

She started taking my dad's side
all of a sudden.

It's ridiculous.

Could it be
that the two of them are reconciling?

That would explain your dad's good mood
and your mom taking his side.

I think you're right.

How would you feel

about your parents getting back together?

I'm not sure.

Hey, Yi-na!

You've got to be kidding me.

Did you reject me
to date this loser instead?

We're not together.

There's nothing going on
between me and Yi-na.

Yet here you are
enjoying each other's company.

Hey.

Who said you could butt in?

Do you have a death wish?

Look at you. Did you just try to dodge?

You're dead meat.

Hey!

Didn't you hear the bell ring?

Get to your classes!

Let's go, Yi-na.

He just ran.

That's it.

He'll soon see what's coming.

Don't you know that her dad's a cop?

Exactly!

We'll come up with something fun.

You got that?

Detective Geum,

please go over this for me.

Sure.

What are you two doing?

Are you all right?

Yes, I'm fine. It's no big deal.

Just a second.
Let me get you some ointment.

But I'm fine.

You're supposed to be crying,
not laughing.

What? Laughing can take the pain away.

Look, I'm bleeding.

NEUROSCIENTIFIC INVESTIGATION TEAM

Dr. Brain! I'm glad you're here.

I have something urgent to ask you.

This way, please. Hurry.

He laughs nonstop like a crazy person

and doesn't feel pain?

That's right.

There's something wrong
with his brain, right?

Yes, you're right.

The poor young man...

Detective Geum's brain

is in love.

What?

Love?

Yes. When the brain falls in love,

it churns out love-related hormones.

If you look at the scan
of a brain in love,

shockingly, you'd find heightened activity
in the same reward center of the brain

that is activated
when a drug addict takes drugs.

The reward center
is activated by food or water,

monetary compensation,

or instinctive arousal.

That's why
the person also experiences less pain.

So that's why he's been...

laughing like that.

But with whom?

Captain Seol?

Did you really not know?

They say even a photocopier
would notice office romance.

If you didn't know,
your brain's even weirder.

Darn it.

Should I get tested?

There's no need.

You just lack awareness.

Please excuse me.

I lack awareness, I'm losing my hair,

and I have no honor or riches.

Why don't I have anything?

All I have are lots of tears.

"Bremelanotide."

"Fructooligosaccharides."

What on earth are these?

Dr. Brain, I'm glad you're here.

I got the analysis back
from the Ministry of Food and Drug Safety.

LEE JEONG-SU,
MINISTRY OF FOOD AND DRUG SAFETY

"Phentermine, alginic acid, caffeine..."

"Bremelanotide"?

What is it?

Hang on.

"Bremelanotide."

BREMELANOTIDE

What is this doing in weight loss pills?

Why? Is it something weird?

This is

an ingredient in Viagra for women.

We've figured out
the cause of your ex-wife's affairs.

So what you're saying is

Yi-na's mom cheated on me
because of these pills?

She told me
she suffered from unwanted impulses.

This must have been the cause.

What...

I'm sorry to interrupt.

I'm here to clean the water purifier.

I think there are
more important matters to attend to.

That's right.

It was around the time
I got on these pills

and started losing weight

that I started feeling those urges.

I thought it was because

my new shape had boosted my confidence.

But I was wrong.

Myeong-sae,
you know how conservative I used to be.

I do.

That's how we got together.

I was the manager of a restaurant,

and he was a part-time employee there.

Here's your order.

-Enjoy your meal.
-Thank you.

-Excuse me.
-Yes?

I'll scrub them with soap.

You just have to rinse them off.

Got it.

We were standing side by side
over a soapy sink,

passing dishes to each other,

when we held hands.

The next day,

I got the catastrophic news.

You grabbed me by the wrist.

That means I've given you my all.

Please take responsibility.

At first, I thought she was just odd.

But she seemed different after that day.

She was the kind of woman
you don't see often in this day and age.

That's what I used to be like.

Nothing bores me more than
stories of other people's first loves.

But yours is very intriguing.

See?

Even a small change in the brain turns you
into a completely different person.

You're right.

Then the reason I acted so promiscuously

was not my fault

but rather my brain's?

It wasn't quite your brain's fault.

It was the drug you ingested,

which makes it a kind of medical accident.

You're right.

It was a medical accident.

Did you hear that?

It was an accident.

You're right. It was a medical accident.

Then...

Myeong-sae,

please

forgive me.

She wants forgiveness?

It was the drug you ingested,

which makes it a kind of medical accident.

Myeong-sae,

please

forgive me.

This is driving me insane.

No wonder...

Should I put on the fall foliage video?

I know you like watching the foliage.

Forget it.

It'll just make me feel worse.

Why? Did Mom say something?

Why? Did Mom say something?

Nothing gets by me, you know.

Yes.

You should know about it too.

Where should I start?

Yi-na, the thing is...

I support it.

What?

I support you and Mom
getting back together.

Don't mind me and go for it.

Good luck!

Myeong-sae,

please

forgive me.

I'm sorry to interrupt.

You interrupt too often.

As your water purifier coordinator,
my job is...

The coordinator for my home
visits just once a month.

Really?

Then you should cancel that contract
and sign with me.

I'll visit five times a week.

You're not listening to me.
Don't you get it?

Stop using the water purifier
as an excuse to visit.

Are you that slow?

Don't you see I'm using it
to keep an eye on my ex-husband?

Detective Geum is no longer
yours to keep an eye on.

He's mine.

Are you two

dating?

Yes.

We're dating.

Okay.

Well,

I totally get it.

I messed up, after all.

But once I go back to normal,

he'll understand everything.

Wake up.

Do you expect he'll understand
after you've cheated on him?

You don't know anything
so keep your mouth shut.

Or I'll hit you.

I'd like to see you try.

Go on.

-Hit me!
-Why you...

Did the captain really say
that she likes you?

Yes, well...

My goodness.
I feel so bad for my lifesaver.

She's really lost her mind.

What on earth are you doing?

Please let Myeong-sae go!

Get up!

Please help my family
get back together again!

Please get up.

Please, I beg you!

-Get up! Please!
-Please, I implore you.

Are they fighting over you right now?

-Please help me!
-Yes.

I can't wrap my mind around it,
but I think so.

What are you doing? Get up.

This is my workplace!

What is the matter with you?

I'm desperate!

Why did you come here? Come on.

Can't you try to understand me a little?

-Come on.
-Why do you think I'm doing all this?

Is there a problem, sir?

No, not at all.

I'm just a little dizzy. That's all.

This is driving me crazy.

Please stop being our coordinator.
I don't want you to come here anymore.

Because of that woman?

Yes.

So please quit.

Don't you remember I paid for your studies

so you could become a police officer?

I'm not asking for credit.

I'm just telling you how much I loved you.

I know that I was in the wrong. But...

I didn't do those things
because I hated you.

I just...

I wasn't myself.

It was all because of those pills.

It was a medical accident.

That's what Dr. Brain said.

I want to get back together.

Hey,

Mo-ran...

Ma'am!

No.

For Yi-na's sake,

please think about it just once more.

Myeong-sae.

Go on. Hit me!

Why you...

What are you doing?

I beg of you.

Please let me have Myeong-sae.

How could you be so shameless?
You cheated on him.

There was a reason I cheated.

It was a side effect
of my weight loss pills.

I'm back to my old self again
after I stopped taking those pills.

What kind of nonsense is this?

I'm telling you the truth.

You can ask Myeong-sae... No, ask Dr. Brain!

Anyway, get up. Get up and we'll talk.

I heard you hurt your head too.

Do you think
your feelings for him are real?

You may be letting your fleeting feelings

rob a family of the chance to be reunited.

Please let me have Myeong-sae!

There you are.

I'm sorry.

I should've told her to quit being
our water purifier coordinator long ago.

Is it really true

that it was a side effect of her pills?

Yes.

Dr. Brain told me

to run a drug analysis
on her weight loss pills,

and they found a substance
that can have that effect.

I did think it was odd.

She wasn't always like this.

Anyway, enough about that.
Let's talk about us.

About the camping trip...

The autumn leaves will be gone soon.

Or have they all fallen already?

How about this weekend?

Sure.

Okay.

Then I should get on
with the preparations.

Please help my family
get back together again!

I beg you!

I did think it was odd.

She wasn't always like this.

I'm back to my old self again
after I stopped taking those pills.

Will I go back to my old self again too?

SEOBU POLICE STATION

I'm so glad you're here, Dr. Brain.

I'm telling you. My head hurts.

Yi-na's mom wants us to get back together.

She keeps saying I shouldn't abandon
the victim of a medical accident.

I'm so stressed out!

Keep being stressed out.

Have you looked into what I asked for?

You mean Hwang Dong-woo?

Yes, I looked into it,

but I didn't find anything different
from what you know.

He was arrested in 1998
for k*lling his patients with medication.

Your parents' accident took place in 1994,

so the chances of him
being connected to the accident are slim.

What about Hwang Dong-woo's
car accident records?

I can't view them because of
the Personal Information Protection Act.

I had to look through old articles
to find this much.

Where are you going?

I'm so distraught.

Let's go for a drink.
Come on. I did you a favor!

We're not exactly drinking buddies.

Hey...

I just told him I was distraught.

Why can't he have one meal with me?

Oh, right. He's a psychopath.

Dr. Brain is a psychopath.

Hwang Dong-woo's a psychopath.

You'd think everyone was a psychopath.

KNUH DOCTOR HWANG DONG-WOO
ARRESTED FOR MURDERING PATIENTS

There weren't many articles on it,
even though it was a major case.

The hospital probably put out a gag order
to protect its reputation.

"Professor Hwang Dong-woo has been
arrested for murdering his patients."

"A nurse who witnessed it
called the police..."

Hello?

You.

You were supposed to visit me,
but you never came.

What's the matter?

Are you unable to leave your house

because everyone found out
you're a psychopath?

You of all people should know
that I'm not such a weakling.

So why would you say that?

I get it.

You must really want to see me.

Of course I do.

I have something to give you.

Oh right.

I have lots to tell you too.

That's too bad.

I've lost interest in your brain
that's filled with resentment,

not murderous intent.

I've found a brain
that is filled with murderous intent

and only just begun to express
its psychopathic tendencies.

You mean the prison guard,

Kang In-h*?

That's right.

I no longer have any use for you.

Nor do I have the patience
to listen to a useless person's nonsense.

I had fun while it lasted.

Please enjoy
the rest of your life in prison.

Oh, right.

I might steal your brain after you die,

so take good care of it.

Goodbye.

DR. SHIN HA-RU

I hate disrespect more than m*rder.

This is beyond disrespectful.

Guard.

Yes, Dr. Hwang.

Things won't go according to your plan.

TRAFFIC ACCIDENTS IN SEPTEMBER 1994

TRAFFIC ACCIDENT DEATHS
IN SEPTEMBER 1994: NO MATCHES FOUND

TRAFFIC ACCIDENTS IN OCTOBER 1994:
NO MATCHES FOUND

Is it because it was a traffic accident?

Serious accidents would remain on record.

PROSECUTOR HAN YEON-HUI

Prosecutor Han, how's the trial going?

Dinner?

How about tea instead?

TRAFFIC ACCIDENTS IN OCTOBER 1994:
NO MATCHES FOUND

DOCTOR AND WIFE
m*rder*d IN PYEONGCHANG-DONG

It remains a cold case.

Out of all my cases,

that was the only one that wasn't solved,
so I remember it like it was yesterday.

What is this about?

Why did you suddenly reach out to me?

There's someone I suspect.

By any chance, was this man...

on the list of suspects?

He was my brother's
research advisor at the time.

He's also a violent criminal
who k*lled seven of his patients.

I'm not sure.

There wasn't a professor
on our list of suspects.

Could he be connected in some other way?

Please,

give it some thought.

I don't have to think. The answer is no.

Please make sure
you're free this Saturday.

I will.

Please help my family
get back together again!

I beg you!

Does Yi-na know we're together?

Well,

not yet.

She's at a sensitive age.

So I wanted to wait for the right time.

How is her relationship

with her mom?

They get along, I guess.

They bicker a lot,

but they do seem to get along
since they're girls.

Hey. Good morning, everyone.

-Hello, sir.
-Good morning, sir.

Thanks to you,
Kang In-h*'s defense won't stick.

I told you I'd destroy his false claims.

You won't even let me
buy you dinner to thank you.

How about a drink instead?

I don't think we're close enough
to get drinks together.

If you want to thank me,

tell Kang In-h* to donate his brain.

Maybe you could offer a commutation
in exchange for a brain donation.

Or just let me strike the deal for you.

I know best how their minds work.

Sure. I'll try to set it up.

Thanks. I'm counting on you.

All right.

Ha-ru,

I have a personal question to ask.

You said last time

that you were thinking about love.

What was your conclusion?

I haven't reached one yet.

Then what do you think about me?

It's brave of you

to want to be involved
with someone like me.

Whoever you are,
regardless of what others say about you,

I can handle you.

Ever since middle school,

you're the only one

who's managed to shake up my brain.

I can see

your brain is in love.

It loses the capacity for judgment.

So?

What's your answer?

All right.

There.

Gosh, my back.

Captain Seol!

You're here. Are you cold?

Here you go.

There.

It's nice and relaxing
to sit out here like this.

We should've done this sooner.

Detective Geum.

Yes?

I have something to tell you.

Go ahead. I'm all ears.

I went on a blind date recently.

Pardon?

He's a decent man with a decent job.

He says he also owns a house.

Of course, he's also never been married.

Being with him made me...

wonder why...

I'm with a man who has an ex-wife
and a daughter in middle school.

I realized I wasn't in my right mind.

I think this is
where we should end things.

Why are you saying this all of a sudden?

Is it because you fought with my ex-wife?

I already told you
that my recent blind date changed my mind.

I'd like to go back
to being good colleagues.

But Captain...

I'll see you back at the office. Goodbye.

SEOBU POLICE STATION

Dr. Brain, I'm glad you're here.

Detective Geum is a mess.

My heart aches as if it's about to burst.

I'm finding it hard to breathe.

They broke up. He must be in shock.

I'm dying.

It looks like a heart attack, right?

I should call an ambulance.

Forget it.
Get him some painkillers instead.

What?

Nice one, Dr. Brain.

I feel much better.

That's amazing.

You cured a heart attack with painkillers?

It wasn't a heart attack.

It was broken heart syndrome.

You see, our brain...

It spews out stress-related hormones
during a breakup.

This greatly reduces cardiac function,

causing the painful feeling
that your heart might burst

and making it harder to breathe.

Those are exactly my symptoms.

Here's an interesting fact.

If you scan the brain
of someone undergoing a breakup,

the areas that are activated

are the same areas that react to
bodily pain like that from a broken bone.

The brain registers the pain of a breakup
and physical pain in a similar way.

That's why the painkillers
made you feel better.

What now? Should he stay on meds forever?

Fortunately, our brain knows
how to overcome breakups.

Really?

That's good to know. What do I need?

You need time, peace,
and to take your mind off of things.

You seem so proud of yourself.

Anybody could have told me that.

Yes. He's just saying
time heals all wounds, right?

Where are you going?

To take my mind off of things.

Should someone follow him?

It's fine. He's not a child.

She's the one who said
she never wanted to break up.

How could she just...

No.

I can't afford to be in love anyway.

Darn it.

What a cliché and old-fashioned way
to take your mind off of things.

Did you come here to drink? With me?

I'm granting you the honor.

You are. What on earth is happening?

I should write it in my diary.

You're not going to
cry into your diary, are you?

I might.

She came and left so abruptly.

It's messing up my mind.

But how would you know how I feel?

You've never been in love,

so you've probably never
gone through a breakup.

I survived a breakup
greater than you could ever imagine.

I lost both my beloved parents.

I think that's when my brain changed.

I can't explain it,
but things weren't the same afterward.

Hey!

We should clink glasses before drinking.

To brains wounded by breakups.

Cheers!

Cheers.

GEUM YI-NA

Is it you?

Yi-na!

This is what you get for ignoring me.

I want to believe my daughter,

but there's all this evidence.

Bring me the proof and then we'll talk.

I'll name the k*ller.

Let's make a deal.

Who is it?

My daughter's life is at stake.

I'll sort it all out for you.

I think we need
a location trace on Dr. Brain.

How about we get started?
