Dr. Brain. What's this about?

Is it because of me?

If you get that, stay away.

It is because of me?

Why? What did I do?

Is it because we fought that day?

Okay, I apologize.

What did you do that you need to apologize?

I challenged you to a fight. Late at night.

Didn't I make you angry?

You did, yes, that was why.

Still, I'm sorry.

Detective.

Detective.

I...

killed someone.

Who did you kill?

Was it Kim Jae Sook, your wife?

It's so reassuring to have you by my side.

I'm staying to help because the case got extended.

I know, and thank you.

Let me be very clear. This is the last case.

Will you stop it? I said I was sorry.

Hello?

Ms. Kim. Are you all right?

Ms. Kim. Are you coming to?

My husband.

He turned himself in.

Yes. He said he killed someone,

and then he stopped talking.

Who did he kill?

He was hit in the head.

I think it was a single blow.

The trophy was the murder weapon.

Why do you think he suddenly killed the neighbor?

That's...

unknown.

Let's ask Mr. Heo.

I'd woken up...

and was coming down from the rooftop after a smoke.

Then I saw him.

We cycle together,

so we hung out a few times.

But he was a bit of a jerk,

so I was never fond of him.

But...

I heard you thought of Cherri as a real woman.

My goodness. This world is full of women.

What kind of loser...

falls in love with a virtual human?

He mocked me. At that moment, I lost it.

So we got into a fight.

You lost it,

so you followed your neighbor into his place...

and beat him up to death with a trophy?

Yes.

At dawn,

when I got home after my workout,

I heard some people fighting.

Turns out, my husband was tussling...

with my next-door neighbor at his place.

Why did you laugh at me?

Why did you laugh at me?

I had a medical condition and even had surgery.

You think it's funny?

- Get lost. - You little...

My husband wanted to turn himself in,

but I told him not to.

I don't really remember what happened after that.

Your husband dropped the trophy, and you touched it?

Yes.

I think so.

This is the trophy, the murder weapon.

It matches the wound on the victim's head.

Two fingerprints were found on it.

One of them belongs to Heo Bum Soo. The other one is Kim Jae Sook's.

As you can see, Heo Bum Soo's print looks clear.

But Kim Jae Sook's is only partial.

She said...

she touched the trophy when her husband dropped it.

Then both of them should be considered suspects.

I don't understand Heo Bum Soo's motive though.

His neighbor laughed at him, so he hit him with the trophy?

He doesn't strike me as the hot-tempered type.

The forensics team conducted a blood pattern analysis.

They think the direction of the blood spatter seems suspicious.

Let's see the photos.

These shoeprints are from Heo Bum Soo's running shoes.

He barged into his neighbor's home with shoes on,

which tells us that he was very worked up.

These are Kim Jae Sook's footprints. She was wearing socks.

The problem is the direction of these footprints.

The blood spatter was found just next to where Heo was standing.

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

I think it's possible.

Enough talking.

Let's do it.

- There. - Okay, got it.

All right. We'll follow the details mentioned in his statement.

The victim and Heo Bum Soo argue.

The moment the victim mocks him and turns around,

Heo Bum Soo loses it...

and hits him in the head with the trophy. Okay?

Sounds good.

Goodness, wait. What was that?

Will you actually hit my head with that?

I must, to figure out the exact direction of the blood spatter.

Goodness. I won't do this. I refuse.

Dr. Brain, you play the victim.

I look nothing like the victim.

You don't look like Heo Bum Soo either.

And I don't look like Kim Jae Sook.

Be quiet!

The roles match your personalities. Just do it.

Dr. Brain.

Don't swing that thing yet.

Gosh, this is making me nervous.

Be gentle, okay?

All right, here we go.

Action.

I heard you thought of Cherri as a real woman.

My goodness. This world is full of women.

What kind of loser...

falls in love with a virtual human?

You...

I will crush your head!

Cut!

That was no good.

Dr. Brain, who said you could make up lines as you went along?

I can't improvise?

Just hit him with that trophy.

What's with this overenthusiasm?

All right. Let's do it again.

Goodness. Being a director isn't easy.

Okay, let's try again.

What kind of loser...

falls in love with a virtual human?

If Heo Bum Soo hit him from that side,

we should've found some blood on Heo Bum Soo's clothes.

But we found none.

Blood was only found on the floor, between the two of them.

Then based on the direction of the blood spatter...

It's more likely that I hit him.

It's not for certain yet,

but based on the angles and the direction of the blood spatter,

it's more likely that Kim Jae Sook hit him.

So...

they're lying to us?

Let's see what their brains want to tell us.

No, I don't want to do that.

You see, I've been under a lot of stress lately.

All of a sudden, I'm experiencing these symptoms too.

I cannot take a polygraph test...

in my current state.

If you refuse to take the test,

you may seem suspicious.

Even if you suspect me, it can't be helped.

At the moment, I'm in no condition to take the test.

Sure, that's fine.

I'll take the test.

We'll get started now.

Who hit him with the trophy?

Mr. Heo.

Who hit Mr. Lee Chang Yong with the trophy?

It was me.

I did it.

It says he's telling the truth.

Goodness. What is going on?

Oh, boy. So he killed him?

You can certainly fool a polygraph.

It's easy to fool a machine,

but you can't fool your brain.

You see, the brain is...

Nice.

What are you doing here?

Hi, honey.

Hey, what is this?

Oh. When I met her at the award ceremony,

I asked her to come and install this for us.

I wanted to take the burden off Captain Seul's shoulders.

Good thinking, right?

What?

What is it?

Oh, my. You're very handsome.

Hello, handsome neuroscientist.

At the award ceremony, I didn't even see you leave.

You left very quickly.

I didn't want to stay there.

Captain Seul as known as Ms. Surrogate Drinker. Hello.

We'll see each other often from now on.

Why is that?

Oh, I guess you don't know.

These days, water system field coordinators...

disinfect the filters and check the machine regularly.

We're supposed to do it once a month.

But since my ex-husband works here,

you get special treatment. I'll visit seven days a week!
