Fatal Promise (Dangerous Promise / Wiheomhan Yaksok / 위험한 약속)

It's the written complaint of the additional prosecution...

on your surgical irregularity and the ghost surgery.

This is your last chance.

Tell me what Jun Hyuk and Mr. Ko are hiding.

Tell me.

I'll submit...

this additional complaint to the prosecutors' office.

It seems to belong...

to your father.

Get out of my way.

I'm a lawyer and she's my wife.

Jun Hyuk's secretary hid...

what you were looking for.

Be more specific.

The asthma inhaler.

It seems to belong to your father.

His inshaler is there.

Where is that? Tell me now.

Then drop the additional complaints.

I asked where that is.

I don't have it right now.

This was the only one that was unusual...

of all the belongings you had when you were arrested.

Did you...

hand it to Jun Hyuk?

Did you?

No.

I hid it.

Where did you hide it?

What did you guys talk about?

I'll head off first.

What did Hye Won tell you?

The one you're finding for.

Dad didn't have his asthma inhaler...

in his pocket when he was being transported?

Nothing like that was with him.

Detective, that can't be.

He can't survive without it.

I heard it wasn't found at the scene either. That's strange.

Someone might've taken away from him or get rid of it on purpose.

Dad!

It's his.

This is Dad's.

Eun Dong.

I found it.

We should calm her down.

It's possible that bloodstain or fingerprint may have been damaged.

I'm sure it's Choi Jun Hyuk.

Let's have it examined first.

If anything that proves this is actually Mr. Cha's is found,

the case will be reopened as a murder case.

And if we even get the culprit's DNA,

we can get Jun Hyuk for real.

I'll get it examined right away.

Dad, goodness.

We need to stay strong.

We're almost there.

As reinvestigation begins and Mr. Ko gets caught,

your father's suffering can be resolved.

Do you think an inhaler could make them reinvestigate the case?

What?

A bloodstain is found on the inhaler.

I mean, it's blood.

A bloodstain?

Whose blood?

Whose blood is it?

It's your blood.

Your blood, Director Choi.

He hasn't woken up from the conscious sedation endoscope, right?

Yes.

I put your blood on it on the day you had your regular checkup.

What?

This was going to unfold anyways.

And I can't be the only one to go down.

If you don't want me to get caught and let everything get out,

you should help me flee from the country.

Hey, you punk! Hello?

What's going on?

A bloodstain? I'm sure I heard you say it.

I and Eun Chan will visit Mom in Oksu-dong.

I'm fine. I'll go.

Listen to your husband.

You're barely standing.

You'll get sick. Just get some rest.

No, let's go together.

I miss Mother and Father too.

Everything will go right with the reinvestigation.

Let's hold out a bit more.

Ji Hoon, let's hurry and go see Grandpa.

Okay. We should go now.

Let's go.

A bloodstain is found on the inhaler.

I mean, it's blood.

It's your blood.

Your blood, Director Choi.

So he used my blood from the checkup.

He's threatening me since he's cornered.

If what he is...

saying is true...

- Grandpa! - You're here, Eun Chan!

Yes, Grandma.

I hear something that belongs to Eun Dong's father was found.

Yes.

It was on the scene, right?

What was it?

An asthma inhaler that he used to have.

What?

Why? Do you know something?

Of course, I do.

If an inhaler was found, I'm sure it's Mr. Cha's.

He couldn't bear it without it.

You must've been so startled.

I'm sorry, sir.

Why would you be?

You were almost killed...

because of my dad during the transplant.

My dad and I will...

live a life of atonement.

Choi Jun Hyuk and his family plotted it.

There's no reason for you and Chairman Han to be sorry.

The one who should kneel and cry for forgiveness is...

not you, but us.

I know that your father was...

sacrificed while he was trying to reveal the truth for us.

On top of that,

Mr. Cha even left me his heart.

But I've lived without knowing that all along.

In a way,

I feel like I've driven Mr. Cha to death.

Dad showed up in my dream once.

He said it was what he wanted.

I know he doesn't regret it.

Yet you met us with all this in your mind.

I can only imagine...

how deep your resentment and sorrow had been.

I don't know if I'll able to resolve your deep sorrow.

You promised you'll be my dad.

I sincerely believe...

that it was meant to be...

that my dad left you with his heart...

out of all people.

That it was destiny.

Okay.

The only way for me and Tae In...

to repay this favor is...

to catch the man who killed your father...

and make him pay for his sins.

The reinvestigation will be open soon.

Good.

And...

I'll go to the hospital starting tomorrow...

to talk to Mr. Cha's colleagues...

and see if I can find any clue.

So don't be discouraged,

and let's find the culprit together.

Yes.

I packed some of the side dishes you and Eun Chan like.

Your egg rolls are the best!

Is that so?

Mom.

What about my favorite?

Didn't you make any for me?

Of course, I did.

I made your favorite, kimchi stew.

I knew it.

You and Eun Dong are...

the only ones who know my favorite food.

Eun Dong.

You can't give way here.

You know what I mean, right?

Yes.

Buddy.

I heard that you've been up for a few nights now.

Go get some rest.

I'm fine.

I'll stay by Seo Ju's side until she wakes up.

Thank you.

I have some responsibility as to what happened...

to Seo Ju.

I'm sorry.

Is this where Mr. Ko was staying at?

Yes.

He must have moved out.

Excuse me,

is that the trash from this room?

Yes.

Here.

You should get something to drink and take a break.

Yes, sure. Thank you.

Could I take a look at this?

- This? - Yes.

Okay.

- Thank you. - Sure.

Isn't this a phone number? The labor union...

Get in here.

Eun Dong, this is the union head of Korea Hospital from then.

The man I grabbed by his collar. Remember him?

So what if you are the union head?

How much did you get paid to denounce an unconscious person?

You better speak honestly.
