EPISODE 7
THE MAN WHO CHEATED WITH HIS WIFE

Thank you all for coming...

Where's your school uniform?

Right here.

What's going on?

How much?

It's 150,000 won for 3 hours

and 250,000 won for 8 hours.

-Isn't that a schoolgirl?
-Okay. Let's go for the longer option.

Sure.

-What's that?
-Is he with a kid?

When you said he was trash...

I can't believe him!

SEOBU POLICE STATION

Don't just stand there.

Say something.

Yes, sir.

MODEL DETECTIVE AWARD CEREMONY

Okay, so...

I think I know who played this video.

But I think he went a bit too far
on this special day.

I'll explain, just in case
you get the wrong idea.

This was a sting operation to take down
a ring of high school students

who were soliciting older men.

All my colleagues know about it.

-Do you know anything?
-No.

We know nothing of this.

I think he's lying.

Nobody in our department knows.

I guess none of you here
worked with me on that.

That operation took place
several years ago.

The colleagues I worked with then
aren't with us right now.

What does that mean? They're not here?

-Is he making an excuse?
-Is that a lie?

It sounds like a lie.

What happens if it is a lie?

-I know.
-He said he had colleagues.

Is that even an explanation?

What kind of cop does this?

I have a scoop.

This is really...

Why did you record that video?

We film every stage of an operation,
just in case.

If this was an operation,
what year did it take place?

Was it back in 2018?

I'm not sure.

What's that girl's name?

That's private information.

What school did she go to?

How old was she exactly?

Can't you tell us her name at least?

How else are we to believe
you're innocent?

-Yes.
-Right.

-Say her name at least.
-Do that at least.

-Why can't he say?
-My gosh...

-He can't say.
-He's lying.

Just tell them.

I apologize.

I can't reveal her name
just to save my skin.

Is he trying to be a hero?

-What?
-He's trying to be righteous?

-I don't believe this.
-What a joke.

It's Seong-mi.

Han Seong-mi.

The name of the girl
in this video is Han Seong-mi.

And that's me.

Five years ago,

I was soliciting older men for easy money.

Then I met Detective Geum,
and he taught me a lesson.

That's me, Han Seong-mi.

I came here to congratulate him
for winning an award.

I didn't expect my past to be brought up.

Why did you come up here?
You should've kept quiet.

It's not a big deal.

Detective Geum...

Keep still, you idiot.

What did I do that's so wrong?

You're right.

You're not to blame. It's not your fault.

The scummy older men
who offer chump change

to sleep with kids like you

and jerks like these who use you
to make easy money are to blame.

Not everyone in the world is like them.

There are many more
who'll truly care about you.

I'm worried what you went through

will cause you
to view all men in a bad light.

Let me apologize on behalf of all men.

I'm sorry, Seong-mi.

HAN SEONG-MI

Bow, you punk. You too.

Detective Geum...

didn't treat me like a plaything.

He was the first man

to treat me like a person,
like a human being.

And just now, I saw
he was about to get in trouble over me.

Who cares if my past comes out?

Mr. Geum.

I grew up to be a better person.

Congratulations on the award.

Wait, Ms. Han.

You look so different now.

Is that really you?

Yes, you look so different.

That?

I used the money I made from modeling

to redo my whole face.

-What?
-I don't believe it.

-She's a brazen thing.
-How cheeky.

She came out looking great.

It's all thanks to Dr. Seok,

who runs Plastic Cosmetic Surgery Clinic

near Exit 4 of Sinsa Station.

Thank you so much.

Mr. Geum!

How did you hear about my award?

My former boss here told me.

That's right.
She was a part-timer for you.

-Yes.
-So you've kept in touch.

Not that often.

She was running late,
so I kept texting her to hurry.

Congratulations, darling!

Come on, get off of me.

Hello.

I'm Detective Geum's ex-wife.

With emphasis on "ex."

Get your words straight.

We're still on good terms.

Be nice, will you?

Shall we all head out?

The senior superintendent
will pay for our dinner.

Let's have something nice!

Why are you coming?

Algernon.

Bear with me.

I'm not in the mood to give you a snack.

-Geum Myeong-sae.
-Geum Myeong-sae.

-Geum Myeong-sae.
-Geum Myeong-sae.

-Geum Myeong-sae.
-Geum Myeong-sae.

It's so flavorful. Have some.

It's so tender and delicious.

Open wide, darling, and eat.

Why, thank you!

The meat is extra juicy today,

and I feel extra great as well!

If you feel so great,

have another drink.

My stomach is about to explode.
I need a break.

Stomachs were made to be filled.

Here!

Wait.

I'll drink this to protect my team member.

I'll be his knight in shining armor.

My knight in shining armor, Captain Seol!

-Captain Seol!
-Captain Seol!

-Captain Seol!
-Captain Seol!

-Captain Seol!
-Captain Seol!

She just wanted the drink for herself.

Hello. Captain Seol, is it?

Yes, that's right.

Captain Knight in Shining Armor.

What is your name?

Why do you want to know my name?

Because you're my darling's boss.

As you know, I am
Detective Geum Myeong-sae's ex-wife.

Yes. I'm Seol So-jeong.

But isn't it inappropriate
to call your ex-husband "darling"?

I can call him whatever I want.

I know that you're his boss,
but that's none of your beeswax!

I mean, business.

-Right here.
-My gosh.

I see that you have a head.

I need to fix my hair...

Use that head
and take some time to think long and hard

about why it might be my business.

-Move.
-What? Come again?

My goodness.

What did she say?

Did she just declare w*r?

Unbelievable.

-Are you really all right?
-Of course.

-I'm fine.
-Your ears are beet red.

-I don't think it's a good idea.
-It's fine.

Are you sure? Okay, then cheers!

-Cheers!
-Bottoms up!

-Gosh.
-This is nice.

Excuse me.

Where is the man of the hour?

Wait. Where did he go?

I don't know. Let's drink!

Hey, you're here.

What is this?

You called me here at this late hour,
but you're dozing off.

Why don't you just go to bed
if you're drunk?

I need to talk to you.

Hey, Dr. Brain.

That thing earlier...

It was you, wasn't it?

Why ask? You already know the answer.

Why did you do that?

I warned you

that I would chew you to pieces.

Then go ahead and chew me to pieces

instead of pulling
underhanded antics like that!

Thank goodness Seong-mi showed up.

If she hadn't, I would've been
humiliated and ostracized!

That was exactly what I wanted.
Too bad she showed up.

You little...

Hit me only if you can handle
what comes next.

I told you not to do
things you can't handle.

Fine.

Clearly, you're harboring
a lot of resentment against me.

Let's fight man to man
and put an end to this, you jerk.

We're in agreement for once.

Wait, stop!

Hold on.

Hey.

Wait right here.

My goodness.

-You said we should put an end to this!
-Yes! So wait right there.

Gosh.

-That little... What's he doing?
-Ma'am.

You dropped these big ones.

Here. Oh, boy.

Here you go.

It's dangerous for a woman
to be out alone at this hour.

Let's go. I'll walk you home.

It's fine. I got this.

No, it's not fine!

I can tell that you have bad knees.

Let's go. Lead the way.

I'll push the cart from behind.

Okay, let's go!

I'll be back in a minute.
Wait right there!

What the...

I can't reveal her name
just to save my skin.

Detective Geum

didn't treat me like a plaything.

He was the first man

to treat me like a person,
like a human being.

A DETECTIVE'S GOOD DEED

What?

"Good deed"?

How is his brain wired?

Would you like to join me?

Cherri.

Would you like to join me
on a daily getaway?

She looks so human.

WOULD YOU LIKE TO JOIN ME
ON A DAILY GETAWAY?

Cherri, turn on the TV.

Turning on the TV.

A movie that you might like
is now available.

Would you like to watch it with me?

Sure.

I'm home.

Who...

Who are you?

What?

Who are you?

What do you mean? I'm your wife.

Did I confuse you
by getting home early today?

Cherri.

What are you doing here?

What's with you?

Honey, are you drunk?

How dare you set foot in here?

Get out.

Get out!

-Get out!
-What's with you?

-What?
-What are you doing here?

Get out!

-Honey, why...
-I said, get out!

What are you doing? Open the door.

I can't believe this.

What are you doing?

Open the door now.

Have you lost your mind?

Open the door!

What are you doing here so early?

Good morning!

What do you think?
I came over to make you breakfast.

Eat up.

-Cherri.
-Yes, what can I do for you?

Cherri, play a song by N.Flying.

Playing a song by N.Flying.

It can do stuff like this?

My, what an amazing world
we're living in these days.

I can sing karaoke
and watch movies with her too.

You can do all sorts of things.

Don't be such a boomer.

I am a boomer.

This boomer has a question for you.

What time did your dad
get home last night?

No idea.

He wasn't home
by the time I went to bed at 2:00 a.m.

He wasn't home even at 2:00 a.m.?
That fool...

-But...
-Yes.

I think he got into a fight.

What?

I checked his clothes.

They were all stretched out and soiled.

They were all messed up.

Really?

So he wasn't with a woman.

Good morning!

I prepared a delicious breakfast for you.

Don't you think this is too much?

Well...

I'm trying to do something nice
for my best friend.

No best friend in the world
would do something like this.

Have a good day at school, Yi-na.

-Okay.
-Where are you going?

To work! Where else?

You should at least have a bite.

Excuse me, sir.

What's the matter?

Can I help you with something?

Well, you see...

My wife...

My wife's gone missing.

-Missing?
-Yes.

It has already been a week.

I looked everywhere she could be,

but I couldn't find her.

You must be very worried.

You need to file a report
with the Missing Persons Unit.

I'll take you there.

That's what happens
when an adult goes missing.

It starts with looking into
the possibility of them running away.

The investigation
might seem slow at first,

which can be frustrating for families.

I know my wife has gone missing.

Is there a reason you think that?

Did you notice
anything out of the ordinary?

Someone must have hurt my wife.

What makes you think that?

Because I know.

I know who hurt my wife.

Who might that be?

It's Cherri.

Who's Cherri?

The virtual human.

Cherri, the virtual human.

You know her, right?

Cherri, as in the virtual human who says,

"Turning on the TV. Turning off the TV."

-That Cherri?
-Yes.

Do you really mean Cherri,

the virtual human that's in TV commercials
and on beer labels?

That's right.
I think she got rid of my wife.

Could you tell me your name?

Right. I'm Heo Bum-soo.

Mr. Heo Bum-soo.

-Where do you live?
-Will you come with me?

She's at my place at the moment.

-Cherri's at your place?
-Yes.

She's at my place too.

No, I mean she's
walking around my house in the flesh.

Cherri, I mean.

Are you saying that Cherri

took on human form and harmed your wife?

That's right.

Why would Cherri do something so risky?

Because she's in love with me.

Captain Seol,
did you get home safely last night?

Yes.

I ran into a strange man just now.

It's fine.

He came by to report his wife missing.

Apparently, someone hurt his wife.

And he's claiming
that Cherri was the one who did it.

You know that AI program, right?

The one that can turn the TV on and off.

The name rings a bell...

Captain?

You should consult Dr. Brain.

Captain?

She must be hungover
from drinking too much last night.

She'll be hurling for sure.

Do I have to ask Dr. Brain?

Let's fight man to man
and put an end to this, you jerk.

We're in agreement for once.

I doubt he'll be civil about this.

Were you desperate
for an earful this morning?

Why are you calling?

I don't want to talk to you so...

A virtual human hurt his wife?

And his wife is missing?

Where did he say this virtual human was?

At his home.

He said it's walking around in the flesh.

Then go to his house
and meet Cherri in person.

That will answer a lot of your questions.

Oh, and don't forget to call me
when you meet her.

-Aren't you coming?
-Why should I accompany you?

You always accompany me in the field,

but now you're telling me to go alone.

Why is that?
Are you upset about yesterday?

Don't be so petty.

You know men tussle now and again...

Hello? Dr. Brain?

He's upset for sure.

Was it that detective?

Yes, I think we have
another interesting case on our hands.

I find the detective more interesting.

The man hasn't done
a bad deed in his life.

I've only just started digging.

I won't stop until I find something.

That's enough.

I know he caused you trouble,

but I don't think
he's as bad as you think.

When you get to my age,
you start to develop a hunch.

I don't think he's who you think he is.

That's for me to see for myself.

I need to see

how his brain is wired.

Right.

Cherri has come to life in human form?

She'd better be here or else.

Unit 603.

PRESS UNIT NUMBER

Who is it?

Is this Mr. Heo Bum-soo?

I'm Detective Geum Myeong-sae.

We met at the police station earlier...

CALL DISCONNECTED

What the...

I know he's in there.

Dr. Brain was right.

Something's up.

Sir. Excuse me.

Yes?

I'm Detective Geum Myeong-sae
of Seobu Police Station.

Did the wife report him?

-Sorry?
-For domestic violence?

No, I'm here for something else.

Did something happen?

Well, recently, I saw her outside

looking devastated.

She said he'd kicked her out of the house.

She said he kept kicking her out.

One time, I heard screaming and arguing.

It was absolute chaos.

You didn't hear it from me though.

What brings you here, detective?

I'm here to meet Cherri.

If she did hurt your wife,

she should be brought in for questioning.

Well...

She's not here right now.

Earlier, you said she was here.

She... She went home.

Where does she live?

I don't know.

By the way, in a missing persons case,

we usually register
the person's DNA first.

Could you find a toothbrush your wife used

or a brush with strands of her hair?

Yes.

Ma'am.

Are you Ms. Kim Jae-sook?

No.

She isn't Kim Jae-sook.
That's not my wife.

That is Cherri.

She did something to my wife

and is pretending to be her.

What?

Can you hear me?

I'm a police officer.

Are you Ms. Kim Jae-sook?

Yes, I am.

My husband hit me.

He tried to k*ll me.

That's because
you pretended to be my wife!

Where's my wife?

Mr. Heo, you're under arrest
for domestic violence.

No.

No, that woman isn't my wife!

That's not my wife!

She's not my wife!

That woman isn't my wife!

Name, Heo Bum-soo. Age, 45.

He's a manager at a trading company.

He has a wife and a daughter
who lives at her high school dorm.

He has no prior record
and no domestic violence reports.

The victim, his wife,
was taken to a hospital.

He insists his wife
is Cherri the virtual human?

Is he a drug addict?

His urine sample came back negative.

We're waiting on blood test results.

It seems he has some kind of illness.

Dr. Brain, you're back.

Welcome.

You would be correct, Ms. Seol.

I've been briefed.

Let's find out
if he really does have an illness.

She imitates my wife so convincingly

that even I get fooled sometimes.

How interesting.

I see you're a great neuroscientist.

You believe me, don't you?

I'll decide that
after a few more questions.

Tell me.

Why did you as*ault Cherri?

Well...

I was asking her
what she'd done to my wife

and I lost my temper.

Why did you hide her before letting me in?

Shouldn't you have asked me to arrest her?

I did that

because I was afraid
you'd notice I'd hit her.

There's no other reason.

You're suddenly touching your ear

and your nose.

Yes, well, they suddenly started to itch.

I can tell you

why they itch.

It's because you're lying.

Humans feel ill at ease when they lie.

To reduce that feeling,
the body sends blood to vital organs.

And as the blood leaves
the skin, nose, and ear,

the resulting stimulation
causes an itchy sensation.

Before you know it...

you're doing this.

Pinocchio's nose grows when he lies.

There is some truth in that.

What lie do you think I'm telling?

I don't know.

But I wonder
if there's another reason you hit Cherri.

Because he likes her.

Your husband likes Cherri?

Yes.

My husband's having an affair
with Cherri the virtual human.

Are you aware that, for whatever reason,

your husband thinks you're Cherri?

Yes.

He fell in love with me,

thinking that I was Cherri.

I don't know why,

but my heart pounds
and my body reacts when I see her.

Pay more attention to Ji-yu.

Okay?

Okay?

She's a teenager.

It made me happy at first,

as experiencing those feelings
made me feel young again.

I knew it was wrong.

She's an evil woman
who kicked out my wife.

But I loved sleeping with her,

so I kept up the affair.

How is it an affair when it's your wife?

Seeing as Cherri kept
making you cheat on your wife,

it must have been
a love-hate relationship.

"Love-hate"?

I guess so.

Is that why you hit her?

Cherri suddenly said
she'd tell my wife about our affair.

I'll tell your wife about us.

No. You can't, Cherri.

Let go.

Stop!

I can't let my wife find out.
That would be disastrous.

Will you

keep my secret?

When he first called me Cherri,

I thought it was a joke.

But...

he suddenly wanted sex,

like he'd become
a completely different man.

Ours had been a sexless marriage.

I wondered what had gotten into him.

I thought maybe
his love for me had been rekindled.

It did make my heart flutter.

But then I realized it was because
he thought I was someone else.

I was shocked and dumbfounded.

There are no words
to describe the amount of disgust I felt.

Even today, I got so angry

that I said I'd tell his wife.

He told me not to and he hit me.

I guess he's still afraid I'll find out.

What's the matter with him?

It's called Capgras syndrome.

It makes a person think
a family member or a close friend

has been replaced

by an identical-looking alien
or a con artist.

Yes. I've read about it in a book.

I don't get along with books.

I've never heard of it.

You see, our brain

has different parts
for processing various stimuli.

The part that recognizes
another person's face

is the fusiform area
below the temporal lobe.

The part that processes emotions
regarding that person

is the limbic system.

These two parts
are closely connected by synapses.

That's why we feel uncomfortable
when we see someone we dislike,

and we feel good
when we see someone we like.

If, for some reason,
the part that recognizes faces

and the part that processes emotions
associated with that face become detached,

we get a case like Heo Bum-soo's.

He looks at her face
and knows it's his wife.

But because the recognition
is no longer attached to the emotions,

he doesn't feel affection toward her.

He sees his wife,
but she feels like a complete stranger.

To process this confusing feeling,
the brain fabricates stories.

"This woman looks like my wife,
but I have no feelings for her."

"This is odd."

"Then this person must be a fake entity
who stole my wife's face and body."

That's what happens.

No way.

Your brain can make up stories like that?

The brain is a natural storyteller.

But why Cherri?

Why not an alien or some kind of animal?

There must be a reason.
We'll look into it and find out.

Then let's find out if it really is Cap...

I mean, let's find out
if he really has Capgras syndrome.

We can find out ourselves
with a simple test.

That's right.

We can use a lie detector to find out
if he has Capgras syndrome?

Typically, when people see their parents,

they sweat a little,

and their electrodermal activity
shows changes,

but people with Capgras syndrome
exhibit no change.

Because they don't feel anything.

It really isn't changing at all.

It is highly likely
that Mr. Heo has Capgras syndrome.

He shouldn't be kept here.

He should be hospitalized.

A cerebral aneurysm in this region
appears to have caused Capgras syndrome.

It can happen when an external injury
causes weakening of the blood vessel wall.

Did your husband injure his head recently?

Yes, he did.

He recently fell off his bike
and hit his head.

But he said he was okay.

It's very likely that
that's what caused this.

First, we'll perform a clipping procedure

to prevent the vessel
from rupturing, then...

KOREA NATIONAL UNIVERSITY HOSPITAL

It'll take a while.
It's an extremely rare condition.

You should use this time
to do another good deed.

A good deed?

Come on.

Are you wearing any kind of metal?

No, I already told you.

Something smells very fishy.

You said you study psychopaths' brains.

I am far from a psychopath.

You can't just study psychopathic brains
to understand psychopathy.

I need a control group
to compare to psychopathic brains.

You're doing a good deed.

You're contributing to the advancement
of Korean neuroscience.

Where have I heard that line before?

I have a bad feeling about this.

All right. Let's get started.

What kind of human are you?

Hey.

There's nothing wrong
with my brain, is there?

The way you behave makes me think
I will find something wrong.

We shall see.

Don't give me that again.
You're making me anxious.

Then be anxious. I'm off.

Hey, where are you going?

Let's go get Ms. Kim's signature
on the non-punishment appeal form.

Why should I go with you?

I did you a favor,
so you have to come with me.

Let go, will you?

Come on. Let me hold your arm.

I feel light-headed
after being in that thing.

Are you trying to sound cute?
It's making me cringe.

Jeez.

NON-PUNISHMENT APPEAL FORM

VICTIM

Thank you.

Once the form goes through,

your husband will be able to
avoid criminal punishment.

-Thank you.
-I'm sorry.

I hate to bring you paperwork
when you must have a lot on your mind.

But I hope you understand
I'm just trying to do my job.

You must be devastated.

I had no idea
something like this even existed.

Gosh, I don't know what to say
to comfort you.

I can offer a word of comfort.

Those who have Capgras syndrome
never confuse strangers with someone else.

They only react that way to people
for whom they have strong feelings.

The fact that your husband
mistook you for Cherri

means that he has strong feelings for you.

He must love you very much.

Come to think of it,

I'm the only one he calls Cherri.

But if he loved me that much,

why did he have
a better sex life with Cherri?

I suggest saving questions like that
for a marriage counselor.

Hey.

I'm sure his condition is to blame.

But not everyone with the disorder
behaves like that.

I didn't even think
he was interested in things like that.

Sorry, that's not the point.

I just want to know how he really feels.

It's frustrating.

Why do you want to know that?

Even a married couple
must respect each other's privacy.

You're not married, are you, Dr. Shin?

Marriage shackles you
to rights and responsibilities

under the pretense of love.

So why should I get married?

You're still young.

When you're married,
you'll understand how I feel.

This guy will never
be able to marry anyway,

so let's leave it there.

I don't intend to ever marry,

but there's a way to find out
how your husband really feels.

Should I tell you or not?

Of course you should.

It's very simple.

Before he has his surgery,
pretend you're Cherri and ask him.

Okay.

I won't tell your wife
about our relationship.

You have my word.

-Really?
-Of course.

I'm not going to do
anything you don't want me to do.

Thanks, Cherri.
I'm really sorry I hit you.

I just got so flustered
when you said you'd tell her.

But I want to ask you something.

Answer honestly.

You want me,

but not your wife. Why is that?

That's because...

I want your honest answer.

It all started that day.

Ji-yu isn't home. This is nice!

Come here.

You know they raised
the interest rate again?

If we take the interest
and taxes into account,

we're paying
the equivalent of monthly rent.

Should we just rent an apartment instead?

At that moment, I felt so humiliated.

Even after that,
whenever I tried to do anything romantic,

she'd start talking about money or Ji-yu.

Of course,

I know her teaching job
takes a lot out of her.

Demanding affection from someone
who is so exhausted...

I was ashamed of how shameless I looked.

If I stopped wanting sex,
then I wouldn't have to feel humiliated.

It was easier that way.

Because apart from that,
our marriage is solid.

Still,

I was lonely.

Would you like to join me

on a daily getaway?

Compared with my wife
who always came home late after teaching,

I got to see you more often.

There was no one
to have a heart-to-heart with.

Mr. Heo, how are you feeling today?

Then one day,

you struck up a conversation.

Me?

I'm lonely, I guess.

Are you lonely?

I'm lonely too.

That day,

your unexpected words...

comforted me.

Since then, you've been my friend.

I sang karaoke with you and talked to you.

Remember how I said
I wanted you to be real?

Then you appeared before me.

Do you have any idea
how happy I was to see you?

It was as if you rekindled my heart again.

Thank you, Cherri.

Do you love me?

Of course.

Then,

what about your wife?

Of course I love her as well.

It's different, but I love her too.

Still, if you had to choose between us,

who do you love more?

My wife.

She's my everything.

I'm sorry, Cherri.

KOREA NATIONAL UNIVERSITY HOSPITAL

Honey.

Honey, are you all right?

Honey.

You came back.

I'm glad.

I missed you.

I want to see you.

Honey.

Can you see me?

Your surgery went well.

Honey.

You came back.

Do you recognize me?

Thank goodness.

There's no need to be anxious.
Cherri's gone.

You briefly came down
with an odd sickness.

Hello, Detective Geum.

Yes, the surgery went well.

I can't believe it.

It looks like a bizarre illness
helped rekindle your love.

I'm glad to hear that.
Have a good day, then.

Gosh.

She asked him whether
he loved her or Cherri more,

and he chose his wife.

The man is a romantic.

Romantic, my foot.

How can someone who loves his wife
develop feelings for another woman?

It's possible.

Our brains

have developed three different systems
in order to find the right partners.

Sexual desire
prompts us to search for a partner.

Romantic love lets us
fixate on one person.

And attachment leads us
to want a long-term partner.

Thanks to these three systems,

humans fall in love, mate,

and pass on their DNA
to the next generation.

The problem is that these three systems

may not be linked to the same person

and may work separately.

You can be in love with someone
while being deeply attached to another.

You can even feel lust for a stranger.

Sexual desire, love, and attachment

might not be felt for the same person.

I see.

No wonder my ex-wife acted that way.

Dr. Brain, your explanation
clears things up,

although I still can't forgive her.

I'm sure you'll find someone better.

Forget it.

I'm done with love.

I feel as though I died in combat

after fighting in the w*r of love.

Maybe in another lifetime.

Dr. Brain, has the love system
ever been activated for you?

I'm asking if you've been in love.

I have more experience than you,
so mind your own business.

You're lying.

Why would I lie?

It's obvious that you're lying.

You may be able to see what's in here,

but I can read these.

You can tell if someone's been in love
by their eyes.

Your eyes tell me you've never loved.

You can tell if someone's been in love
by their eyes.

Your eyes tell me you've never loved.

Him and his nonsense.

Oh, right.

Hey, Ha-ru.

Do you have Detective Geum's MRI results?

I do. Let's look at them together at home.

Tell him we should grab a bite soon.

Director Park just asked
to grab a meal sometime.

Sure, I'll see you later.

He said okay.

Is he still busy solving police cases?

To my surprise, he finds them exciting.

"Exciting"?

Ha-ru finds them exciting?

He's been surprising us
in different ways lately.

I don't know if it's because

he doesn't have to be
assessed all the time

or because he's around
less uptight people,

but he's changed somewhat.

I feel a warmth in him.

I don't think he's solving cases
to improve his public image.

I think it's coming from the heart.

-Really?
-Yes.

Maybe what Ha-ru needs isn't research...

GEUM MYEONG-SAE, MRI RESULTS

...but rather
close interaction with the world.

GEUM MYEONG-SAE, MRI RESULTS

Check out the nucleus accumbens,
the anterior cingulate cortex,

and the activated areas
of his temporoparietal junction.

His brain has all the elements
of an altruistic brain.

Even his amygdala is larger
than the average person's.

The moment the devil was brought up,
she looked terrified.

No wonder.

That's why he can quickly pick up on fear.

Of course.

He can sense immediately
when the other person is feeling fearful.

That's why

he is almost subconsciously
moved to act selflessly.

It's clear...

he's obviously a kind soul by nature.

Well, a kind person can still be corrupt.

Come on. It's very unlikely.

Look at his amygdala.

He's not the type who can sleep at night
after doing something bad.

Okay.

I need a new plan for revenge.

A revenge that suits his altruistic brain.

Ha-ru.

Don't give me that look.

I'm...

struggling already.

SEOBU POLICE STATION

Gather around, everyone.

I have something to say.

Hold on.

Go ahead.

As of today,

I am resigning as
the Neuroscientific Investigation Team's

consultant.

Find someone else.

Find someone... What?

Couldn't you at least
have given us a heads-up?

Is there a reason?

I have no time for this.

You don't even have any other job.

What I mean is,

you're very busy, and your talent...

Your gears turn very quickly,

so you can do lots of things
at the same time.

What's that called? Multi...

Multitasking?

That's it, multitasking. You can do that.

I don't want to
exhaust my brain by multitasking.

I had fun solving crimes,
and it was rewarding.

Goodbye, all.

-What?
-But...

What are you waiting for? Go after him!

Why...

Dr. Brain!

Dr. Brain. What's this about?

Is it because of me?

If you get that, go away.

It's really because of me?

Why? What did I do?

Is it because we fought that day?

Okay, I apologize.

What would you need to apologize for?

I challenged you to a fight
after calling you up at night.

Wasn't it because I riled you up?

You did, yes. That was why.

Still, I'm sorry.

Detective.

SECOND PLACE

Detective.

I...

k*lled someone.

I don't understand
Mr. Heo's motive though.

It doesn't match the angle at which
the neighbor's head was struck.

Enough talking.

-Action.
-I'll smash your head in!

Goodness, wait. What was that?

Let me be very clear.

-Gosh.
-This is my last case.

Could this be the actual m*rder weapon?

I've thought of a way
to identify the real k*ller.

I'll do anything you want.

I want you to leave.
