Don't do this, Si Joon.
It's not his fault.
The last person your mom was with...
was Ji Na.
She found out your mom was here to see Poong Do,
so she lured her to the rooftop.
I'm positive.
Your mom's dead because of Ji Na.
Yeo Ji Na.
- Si Joon. - Leave him.
He won't hear anything you say.
Are you okay?
Why are you here?
Did you follow him?
Just out of concern.
He rushed out like he wanted to wreak havoc.
He'd want to.
I bet he hates everyone he sees right now.
Think how it'd feel if someone you talked with over breakfast...
suddenly disappeared.
It's even worse...
if you don't know why the person left.
It's enough to drive you mad.
Why are they all there?
I must find the ring.
If that is true,
I will kill you myself...
Yeo Ji Na.
Let me take you to the funeral hall.
What you said suddenly made me wonder.
About my birth parents.
I wonder what it was like for them.
How did they feel...
when I disappeared?
They must think I'm dead.
That must be why they aren't looking for me.
Did no one even report you missing?
How could that be?
If you were in the sea, there must've been an accident.
That's why I wondered if I'd been abandoned.
Maybe they didn't look for me because I was unwanted.
Maybe that's why I felt all the more grateful...
to my adoptive parents.
There must've been a reason.
Why wouldn't they look for such a pretty daughter?
I bet they couldn't even look.
Come along.
She's so young.
Chung Yi was just about her age too.
Two people died overnight...
and the house of one was burned.
The wife's dead, and the daughter's missing.
A family was wiped out.
Did you really not see anything?
Wiped out?
I should've looked for her relatives.
I was blinded by my will to survive.
What's the matter? Is something wrong?
According to the police,
it's likely that Auntie killed herself.
They say she went to Jubo Group alone and jumped off the roof.
Does that make sense?
Insurance companies don't pay a dime for suicide.
Woo Yang, are you worried about the insurance right now?
No. It's not like it's my money.
Your aunt left it to Si Joon and Yeol Mae.
The money she worked so hard to save up might disappear.
Even so. How can you mention money at a time like this?
I'm sorry. I'm worried too.
This isn't right.
If we have a funeral...
and cremate her body,
won't the truth disappear with her?
Shouldn't we get an autopsy?
An autopsy?
Hey, that's a bit... How could you do that?
But...
What should we do?
Where on earth is Si Joon?
Didn't you run off after him?
He's not back yet?
What's he doing?
What now?
Are you with Si Joon?
Why are you asking me about him?
Are you sure? You haven't seen him?
I haven't. Will you stop asking?
Hey.
Darn her.
Did she tell Si Joon about me?
That's why she thinks he came to me.
What is he doing? I'm scared again.
Do you know what I heard today at Jubo Group?
Yeo Ji Na's going to marry the chairman.
He gave her this ring,
so she's going to become the chairman's wife.
She'll come back to you?
Is she insane?
What did you and Ji Na get up to?
(Signatures for petition)
Heon Jeong made me a petition for people to sign.
It tells the story of how you were wronged.
Let's get people to sign it and hand it in.
Stop it.
Mom...
You're home.
I never saw you drink.
Really?
Are you upset about something?
Did you hear?
Someone jumped off our building today.
An outsider jumping off our building's roof?
We should overhaul Security.
Okay.
Did you get up to something with Yeo Ji Na today?
I saw her leave your office.
She didn't look pleased.
I told her off for lying about her degree.
She lied about that?
How come?
I guess...
it's my fault.
I should've vetted her properly.
You chose to marry her.
I'm sure she had a good reason.
You may have already known about it.
But because this is related to her recruitment,
I needed to hold her responsible.
I'm not sure.
I'm pretty shocked too.
So you two...
talked about that?
Yes.
I see.
Don't drink too much.
How can you leave without leaving us a word?
You need to be my drinking friend, Ms. Jeong.
I still have to ask you how I can bring up Bok Nam.
I was going to give you...
the clothes I made when they are released.
I'm sorry, Ms. Jeong.
I couldn't protect you.
I left you to put up a fight all alone.
I'm sorry.
Baek Si Joon.
Why aren't you up yet?
Eat up and go to school.
You'll be late again.
- Mom. - My gosh.
Goodness, why is your room such a mess?
I told you not to touch my notebook.
I need my privacy too.
I'm going to spank you.
Okay.
Mom.
I need to go see Ma Poong do.
I will tell him everything about Yeo Ji Na.
That ring will be my evidence.
Yeo Ji Na, you brat.
You will be cursed in trying to cut off your family.
Should I tell everything to Seo Pil Doo?
Or should I keep everything as a secret until the day I die,
just as I have until now?
Seo Pil Doo.
(Naming, fortune-reading, divination)
Please make sure...
that Moo Sim, that poor girl,
rests in peace...
without holding any grudges.
Let's go.
Please do not let her turn into a ghost...
who will come back to ruin Ji Na's future.
Please help her rest in peace...
as she leaves back all the regrets of her life.
I pray.
I pray that she will rest in peace.
Chung Yi, I hope you aren't straining yourself.
You should go back to work too.
I'm okay.
I'll be back after work.
Hope you two can make it through then.
I can't believe Si Joon.
I got a call from the police...
asking if we really want an autopsy.
I'm not doing an autopsy on her.
I cannot let her suffer even after death.
Then do you want to admit that she committed suicide?
Who said I'll admit that?
I will find out the truth.
I will let her go in peace and find out the truth.
So don't bring this up again.
Si Joon.
Are you sure about that?
About how Yeo Ji Na and Mom went to the rooftop?
I saw them go up the emergency stairs and followed them.
The door to the rooftop was locked,
so I couldn't go out there.
And Mom died after that?
For now, yes.
I really don't want to believe...
that Yeo Ji Na would go that far.
But now that the security footage is rigged,
I am even more convinced.
Yeo Ji Na couldn't have tampered with Jubo Group's security alone.
Is that even possible?
Isn't Ma Poong Do behind her?
That's not the case.
How can you be so sure?
Ma Poong Do and Yeo Ji Na are dating.
It's not the case.
Poong Do has nothing to do with this case.
Trust me.
Do you know who Seo Pil Doo is?
How do you know him?
I heard he's the vice president of Jubo Group.
He's the guy I saw in front of Poong Do's house, isn't he?
May I help you?
You're right.
Why? Did you find out anything?
Si Joon.
Listen to me.
Yeo Ji Na and Seo Pil Doo are on the same side.
I believe Seo Pil Doo tampered with the evidence...
for Yeo Ji Na's sake.
- The bag? - Yes.
Ms. Jeong was with a bag on the security footage...
when she was at the lobby.
Let go of me.
But there was no bag anywhere around where she fell...
nor at the rooftop.
It wasn't among her articles either.
If the accident happened over a fight in trying to take...
something that was in that bag,
then that must be why the culprit took the bag.
We must find the evidence before they destroy it.
(Do not enter)
Why is this locked?
They say the culprit always comes back to the scene.
It was real.
Is it human instinct to want to see...
what they have done?
What were you going to do on the rooftop?
Did you drop anything?
A decisive evidence that you were with Ms. Jeong?
Silence.
I can't believe you came back here.
You really gave up on living like a human.
Where is her bag?
You took that bag, didn't you?
Stop talking nonsense!
Why would I take that?
You're harassing me because you saw me yesterday, right?
Fine. I met Ms. Jeong.
She threatened me, saying she'd go to Poong Do.
So yes, I wanted to talk to her.
But that's all.
So what?
She went onto the roof alone?
Too bad if you can't believe it.
But that's the truth.
The truth?
Now just forget about what happened.
It's not like I don't feel guilty.
But doing this won't bring her back.
What are you doing?
Don't you dare talk about truth.
The deities know what's true.
They know what you did.
Ms. Jeong knows.
She killed herself?
Yeo Ji Na, don't you fear anything?
You can fear all you want.
I fear nothing in this world.
Won't it be all over once we die anyway?
(Vice President Seo Pil Doo)
I need you to unblock the roof.
I heard that Security decided to cordon off the roof.
I need to go up there. I lost something.
Not right now.
Security has an eye on the place.
Then when can I go up?
It's urgent.
The Jeong Moo Sim who wrote that petition...
runs a short-rib restaurant?
She has a son and a daughter?
What's the son's name?
Baek Si Joon?
So the Baek guy is Baek Si Joon.
Yes. I'd like to meet her.
Where's the restaurant?
What? She's dead?
Why?
Suddenly?
Okay. Find out exactly what happened.
Are you a Grim Reaper? Why are you in black?
It's not me. Someone else died.
Mom. I'm really sad.
Who died that got you sulking since yesterday?
It's not like you know.
See you later.
My goodness.
If Jeong Moo Sim's dead,
then Yeo Ji Na's life just got easier.
(Joint Contract)
This is the factory in China that Seo Pil Doo recently signed.
He signed a deal with a new textile factory?
I bet he's anxious because...
he doesn't know when I'll return.
He'll be trying to accumulate funds.
People inside and outside the company are talking.
Then there was the suicide yesterday.
I read about that not long ago.
It must be really tough for Poong Do.
I should speed things up.
("Female in Her 50s Who Committed Suicide Was Mentally Ill")
There's no way.
This isn't true.
Auntie wasn't depressed.
I know. Who wrote this?
Mom left us...
because of me.
Why would you say that? Why would it be your fault?
She went to that company to see the evil woman.
The papers Mom was collecting.
That evil woman burned them all up.
Mom got angry...
and went to tell her off.
Because the evil woman works there.
Who's this evil woman?
I tried to stop her from burning the papers.
The fire was too hot.
I'm sorry, Si Joon.
I'm sorry.
Who was it? Who's the evil woman?
Who is it?
Yeo Ji Na. She's evil.
Chung Yi's sister.
("Female in Her 50s Who Committed Suicide Was Mentally Ill")
So that was it.
She was mentally unstable.
So she came here to kill herself?
- It seems a bit odd. - Right.
It would. She was mentally unstable.
Right, Ms. Sim?
(Team Leader's Office)
She got upset because you cracked a stupid joke.
What?
I found it.
This USB flash drive came in the chicken?
Yes.
I almost lost a tooth.
It was like a surprise proposal.
It's from the chairwoman, isn't it?
I think so.
The deposit is way over the top.
I bet he's stashing it somewhere with a secret ledger.
Grandma just dropped me a huge lead.
I should play along.
I'll call you back.
Hello, this is Ma Poong Do.
Baek Si Joon?
Where is he now?
("Female in Her 50s Who Committed Suicide Was Mentally Ill")
How could they print something like this?
This is killing her twice.
I had Marketing deal with it.
Don't get too upset.
Yeo Ji Na...
I can't even find her.
I want to find her and make her pay.
She'll be very busy with a visitor.
A visitor?
Ms. Yeo. You have a visitor.
I do?
A visitor?
How did you get in here?
Shall we talk here or will you follow me?
I have nothing to say. What do you want to talk about?
About the flyer that's about you,
about our baby, and my mom!
There's nothing to discuss?
Shall we talk here or in front of Ma Poong Do?
Why did you want to come here?
We could talk somewhere else.
Do you feel guilty?
Do you even have a conscience?
What does that mean?
I really had nothing to do with what happened to your mom.
I explained to Chung Yi too.
Talk to her.
I feel bad that she passed away.
We weren't on great terms,
but I'm a human too.
How can you treat me like a murderer?
Yeo Ji Na. You must have forgotten.
It only takes a moment for someone to become a murderer.
This ring.
Where did you get this?
- What's with you? Let go of me. - This ring!
You killed my mom.
You killed her!
Si Joon!
Why are you doing this? Have you gone insane?
Wasn't it enough to ruin my life?
How can you do that to my mom?
Stop it. Please spare me. Spare me, Si Joon.
Die. Just die!
I will kill you here and die with you!
Si Joon, don't do this.
This is wrong!
(Blessing of the Sea)
My innocent mom became a victim...
because of this fake lure.
If Ma Poong Do got rid of her long time ago,
this wouldn't have happened.
How can you two hug each other and smile?
How do you call yourselves human? You jerks!
Heon Jeong!
You will lose everything because of that ring.
Ms. Jeong will not let you go on.
This is a delivery for you, Chairman Ma.
What is that?
The final whereabouts of Ms. Jeong.
How can the deleted footage come back?
- Maybe someone got to the server. - What?
- Are you Ms. Yeo Ji Na? - What is it?
Please come with us to the police station.
