Please let me see the chairman.
You can't see him right now.
Let her see him.
She has a right to see the chairman.
I'm not saying she can't see him.
Just wait until Dr. Yu comes out.
Give her some time alone.
Uncle.
How could you leave like this?
You shouldn't have told me then.
You should have taken it to your grave.
Let's go.
Since he repented like this,
am I supposed to forgive him now?
No.
You don't have to.
And forgiveness should come
after setting everything right
and when there is nothing else to do.
It should be the last step.
It's too soon.
Rita.
You should have called me first.
Let's talk alone later
after I send my uncle off.
Now you've really become the owner of this tree.
But...
you don't look very pleased.
A tree needs to drink water to grow,
but I guess this tree will drink blood from now on.
A tree...
won't grow quickly on water alone.
Good luck with the shareholders' meeting.
I heard the majority is on your side.
And...
let me know
if anything is in your way.
What is it?
Do you think I tied the rope around the chairman's neck?
There was no need to do that to someone who only had one or two days left.
He died because of you.
No.
He wanted to control his fate himself.
Actually...
I went to tell him he didn't have much time left.
So?
Did you really tell him that?
No.
He was sleeping, so I left.
I suddenly felt sympathy for him.
We sell our souls for eternal life.
But he looked like he was selling his soul
just for 100 years.
How sad is that?
Whether it's eternal life or 100 years,
it doesn't matter.
If you live just one week as a monster,
you are a monster.
What is your standard for being a monster?
Me?
Then your standard should be raised.
In this day and age, that standard is too low.
I had thought
Uncle would meet Sister Sylvia after he died.
I guess that will be difficult now, right?
I'm curious about something.
Why did he suddenly become repentant?
Agent Number Five.
The drug that he was given?
Yes.
Intelligence agencies used to use it to force confessions.
It lowers your defensiveness and self-consciousness,
making you tell the truth.
So it was the drug that made him do it.
That's what I thought at first
since people don't change easily.
However...
I think I was wrong.
A drug can make you tell the truth,
but it can't make you repent
to the extent of taking your life.
The confession he made to you
was probably the final
and the most honest confession of his life.
It's tonight.
Yu Rita will probably go home tonight.
She must be tired from the funeral and everything.
I need to ask something again.
If Yu Rita must be killed?
Of course.
But she just buried her uncle today.
So?
It's just a slightly special day, that's all.
Go with Cheol-hun tonight.
Do you have something to say?
-I can go alone and-- -Go with him.
Rita.
I don't need to play this for you, do I?
You were just like my uncle, weren't you?
You loved me and were good to me out of guilt.
Rita.
Fine.
Let's say that's still love.
In consideration of that love, I'll give you a chance.
Turn yourself in along with the men you hired.
Rita.
This is the last chance I'll give you.
If you don't do as I say,
I will send this recording to all the shareholders.
Rita.
You knew my uncle was dying, didn't you?
Were you behind it too?
No!
I had nothing to do with it.
Still, you knew.
When I was growing up,
I had so much love from you guys.
I was truly happy.
I had no idea that love was in reality so disgusting and despicable.
-Rita, I-- -Don't even try.
Any more excuses will be outright disrespectful.
Rita!
My feelings for you
were genuine.
Lies...
are used to fool others at first.
However, they are...
eventually used to fool yourself.
As expected, everyone is almost fully infected.
Our research can't keep up with their worsening condition.
If it is like the director said, we'll just have to watch everyone die.
Dr. Park.
May I ask for a big favor?
Sure.
I need your blood.
I've only seen it in videos until now.
I know you're worried.
I heard from Hyeon-u.
I know he's the only one who handles your blood.
I assume
that is how distinctive and dangerous your blood is.
-If you don't feel comfortable about it-- -No.
I'll do it.
We need to save the patients.
Thank you.
Now you've really become the owner of this tree.
I guess this tree will drink blood from now on.
A tree
won't grow quickly on water alone.
I'm sorry for your loss.
Thanks.
Dr. Yu.
Yes?
I know I may be out of line,
but I need to say this.
Please be strong, and don't skip meals.
Make sure to get enough sleep too.
You really are out of line.
But thanks, Ga-yeon.
This is the first time you've called me by my first name.
Is it?
I should have done it sooner.
I now understand why Dr. Park hired you.
You understand pain better
than anyone else does
and overcame it yourself.
Hopefully, I can become like you with time.
YU RITA IS IN DANGER
Good night.
Dr. Park?
I don't know if I should say this,
but Dr. Yu seems to be in a lot of pain.
I'm saying this not as your mentee,
but as a fellow woman.
Please stay with her tonight.
Please.
There's a liver transplant patient from Daegu, right?
Yes, Dr. Park Ji-sang's patient.
When is his surgery?
You don't need to take me home tonight.
It's okay.
I'm really okay.
I think I'll fall asleep as soon as I get home.
Then go sleep. I'll just stay next to you.
Don't be overprotective.
You might have a nervous breakdown.
Stop talking and let's go.
Yes?
Why so suddenly?
Fine.
What is it?
There's an urgent liver transplant.
It's supposed to be tomorrow, but his condition got worse.
You should go.
Go.
I'll probably be in the O.R. for at least ten hours.
So, text me before you go to sleep
and when you wake up.
Okay.
Dr. Park.
I thought you didn't have any surgeries tonight?
Choi Nam-su's liver transplant has been brought forward,
but the donor hasn't gone into surgery yet.
It's running late.
Do you want to scrub in?
I would like to do that, but I need to go home tonight.
Okay. Go then.
Get out of there now. You're in danger.
I'll go in alone.
Director Lee told me to go with you.
It's just Dr. Yu.
I can handle it alone.
I don't want you to see me kill someone.
Fine.
If anything happens, call me.
Thanks.
Dr. Yu.
What are you looking for?
Director Lee.
"Get out of there now. You're in danger."
What an urgent text message.
It's a message she shouldn't see.
Why did you do it?
Explain yourself so that I can understand.
I thought it was the right thing to do.
Why?
I thought Joo Hyeon-u and Yu Rita didn't need to die.
Are you saying I tried to kill people who didn't need to die?
This isn't a betrayal then.
It's your own humanitarian judgment.
Do you also
see me as a monster?
No, it isn't like that.
You kept making such extreme decisions.
I was scared and you seemed unfamiliar, so--
If I hadn't made those extreme decisions, you wouldn't be alive today.
You too!
You were saved by my extreme decisions!
That's also what made our plans come to life!
But what?
I looked unfamiliar?
I told you to keep an eye on Park Ji-sang,
but you became his real mentee.
No, I didn't.
I still consider you as my father, and I respect you.
I just wish you would change.
We can still pursue our goal even if...
-Director Lee. -Change?
That's just a rationalization for your betrayal.
This world...
has been tainted by countless betrayals.
Betrayals are selfish. It only serves themselves.
If you don't accept me as I am,
you'll simply have to disappear.
What are you doing?
I'm sorry,
but you can't do this to Ga-yeon.
Please forgive her. Give her another chance.
Or I will...
Director Lee.
I told you, didn't I?
I told you not to become my weakness!
Director Lee!
We only want one thing.
We just want you to maintain the heart and eyes
you had when you saved us. That's all!
Why can't you understand that?
Both of you, get out.
Get out of my sight.
I thought I told you to leave.
I will never leave you.
I swore that to myself
the moment you saved my life.
Ga-yeon feels the same.
What if I don't need you...
And what if I kill all of you?
It won't change anything.
Please.
Please don't abandon us.
Gosh.
Why did I do that?
What is it now?
I'm sorry,
but let me draw your blood again.
Again? Why?
Well...
I forgot
to turn the power back on after cleaning the fridge,
so your blood samples are spoiled.
Are you serious?
You should have been more careful.
-How annoying. -I'm sorry.
Didn't you get enough sleep?
No, I got more than nine hours of sleep.
But my head hurts, and I feel feverish.
That's because you've been stressed out.
Why do I feel unconfused?
Dr. Yu.
Yes?
What am I doing?
What's up so early in the morning?
Listen carefully.
Yes, Director Yu.
Did you send the results to Hyeon-u?
Yes, I did.
HYEON-U
Did you get the e-mail from Dr. Choi?
Yes, I'm opening it now.
Darn it.
-What is it? -It's as you expected.
I found a trace of tinium venovital in Dr. Yu's blood.
What's that?
An analgesic. A sedative.
-Is there anything else? -No.
How could she have been given a drug without knowing it?
It's colorless and odorless, so it could have been sprayed in the air.
It could have been put in her food or water as well.
I think I drank some water as soon as I got home.
Is there nothing he won't do?
Where are you going?
The more I get to know you, the more I like you.
I like you so much that I want us to become friends.
Showing your weakness like this
may be making yourself vulnerable.
But...
you're so smart.
This isn't showing your weakness.
Rather, it's showing your trust in me.
Because you and I
are in the same boat now.
The bottom line is that
Dr. Yu is a problem.
You took care of her like your own child,
so you don't want to harm her.
In that case, I'll have to do it for you.
Don't worry about it.
Just focus on the shareholders' meeting.
Please make sure she doesn't feel any fear or pain.
Please.
Of course, I will.
Dr. Park.
What did you do to Dr. Yu?
Pardon?
Why did you give her
tinium venovital?
Tell me.
I can't ignore it any longer.
I don't understand what you mean.
You're the one who texted me that Hyeon-u was in danger, right?
You called me to check if he was safe, pretending to be asking about an order.
But...
there was nothing wrong with the patient's medication.
There was no mistake!
And yesterday,
you told me to stay with Dr. Yu.
That was your way of telling me to keep her safe.
But I suddenly had to scrub in,
so I couldn't stay with her.
I'm sure Director Lee changed the schedule
to keep me away from Dr. Yu.
When you saw me in the lounge, you were surprised
because you realized the situation had changed.
What happened last night?
Tell me.
How did you know about me?
Quickly.
Tell me right now.
Doctor...
I mean, Director Lee
ordered me
to kill Dr. Yu.
You're taking a while.
I'm sorry, Rita.
I need time to prepare myself.
There are things I need to take care of too.
There are plenty of people who could take care of your duties.
Give me a little time.
I'll finish up and do what you said.
Vice Director Choi.
Please don't disappoint me.
I couldn't kill her.
It wasn't right.
How long have you been working with the director?
When I was young,
I was dying and he saved me.
Are you the girl from the picture?
I've done so much wrong to you.
I'm the one who switched out your drug
and shot you on the neck in the ward that was under construction.
I told you,
I'm not a good person.
Then why did you help me?
I thought that was the right thing to do.
If you care about what's right,
you shouldn't work for the director.
Even if he's wrong
and doing something bad,
a daughter can't abandon her father.
I hope...
you will consider changing your mind.
I'll pretend not to know anything
until you make that decision.
Dr. Park.
Go on.
Ga-yeon.
Yes?
Thank you.
What's with all the water?
Throw out everything you have and drink only this.
I was going to order a new water filter.
I can't trust that either.
Just drink this.
Is that a new doll?
Do you know what her name is?
What?
Yeong-hui.
Park Yeong-hui.
Once everything is taken care of,
let's go to Kochenia together.
Let's give that doll to Yeong-hui.
Okay.
Let's go together.
Did anything happen today?
No.
Nothing.
I'll give you a chance to save our relationship.
To be honest,
I didn't plan to kill Dr. Yu.
I was testing you.
In that sense, you lost my trust.
But this time,
you must kill her.
I haven't changed my mind.
There is no reason for Dr. Yu to die.
Then Na-jeong will die.
What?
The child that you care so much about.
Director Lee.
I'll have her fall from the roof before your eyes just like you did
so you can remember how you felt.
How could the blood...
It's completely different from other infected blood.
No matter what biochemical substance is injected,
antibodies form within a minute.
Even among the infected,
Dr. Park
is definitely a mutation.
That's right.
I remembered something from Dr. Jung Han-su's notes.
Infected people can't have a child. Fertilization is impossible.
But Dr. Park Ji-sang was born of infected parents.
This was the reason VTH-16 kept failing, isn't it?
That's right.
Each cell is like an antibody.
That's why the injected antibodies kill every cell
when they're supposed to only kill cells with VBT-01.
They kill both enemies and allies, so to speak, right?
Even if we use an anti-cancer substance targeted on the stem cells,
it will kill every cell.
Then we'll have to restructure the cells
so that the antibodies and anti-cancer substance
can distinguish VBT-01 from normal cells.
Exactly. That's the answer.
But how?
Send this to Hyeon-u.
Okay.
I'll go and brief him in person this time instead of sending an e-mail.
An e-mail would do though.
You lasted longer than I expected.
Is that all you could do when you ran away?
Please forgive me.
I was...
I was thoughtless.
Stop.
Stop it!
But Director Lee...
I'm suddenly curious about something.
Can psychopaths
repent?
And...
respect others?
He really is Dr. Jung Han-su's son.
Is this helpful?
This is beyond helpful. He just solved 70% of the problem.
Yes!
But the remaining 30% is the problem.
Infected cells need to be differentiated from normal cells.
We'll have to figure it out.
If you do find a solution,
it will help both Dr. Park and the patients of Ward 21A, right?
Yes. They will become human again.
It could be turned into a virus too.
That would be so great.
Right.
I should go home now.
Already?
Do you have any other plans?
No.
I'm going to have some beer and catch up on TV dramas.
TV dramas?
I have plenty of beer here too.
Then, sure.
I'll have just one can.
Okay.
DO VAMPIRES TRANSFORM WHILE KISSING?
THEY DON'T. NO PROBLEM KISSING.
WHAT WOULD YOU DO BEFORE YOU DIE
IF YOU COULD DIE?
I don't like that.
I want another answer
to the 100th question.
When did you first meet Dr. Park?
Well...
it was six years ago.
I had been regularly posting articles on the vampire virus
on the website of the World Infectious Disease Academy.
Everyone else thought I was a lunatic.
My lab kicked me out,
and all the scholars shunned me too.
Goodness!
They don't know how to judge people.
They only believe what they see.
The first person who acknowledged my papers
was Ji-sang.
I learned about his condition then,
and we've been together ever since.
Weren't you scared?
When I first saw him transform,
I couldn't sleep for three days.
But I got over it.
Now you two are like brothers.
To me,
he's more than a brother.
Why?
He knows me better than anyone.
You know there's a saying that goes,
"A hero will die for those who truly acknowledge him."
That's why I like the two of you.
You truly care for each other.
What's with this mood? It's getting a bit cringy...
Su-eun.
This is a bit bland.
Do you want to mix in some soju?
A soju bomb.
Excessive drinking may harm your mind and body.
This much is fine, Luuvy.
We can handle this much.
I'm in.
Gosh!
Continue with what you were doing.
Luuvy, nothing happened last night, right?
Exactly six hours and 14 minutes ago, this is what you looked like.
Three.
Two.
One.
This is what excessive drinking can lead to...
Well...
Are you done?
Yes, it was Dr. Lee Ho-yong's surgery.
Okay. Good work.
Right, Ga-yeon.
Do you want to have dinner together sometime soon?
Okay. Sure.
Good night.
Dr. Yu.
Yes?
What?
Nothing.
Okay.
No.
This must be wrong.
It can't be.
Come in.
What brings you here?
I figured out a way for the cells
to be distinguished.
You did?
Yes.
It's no longer VTH-16.
It's VTH-17.
A perfect antibody to cure the virus.
Great work, Hyeon-u.
But...
why do you look so sad?
Make no mistakes this time.
He should have made progress by now.
I'm sure he will hide it from me.
Last time, my guys didn't know anything,
so they brought back some ridiculous data.
Right, the one about allergies.
This time, you'll make sure the data is relevant.
Bring back every useful piece of data.
I'm sure the files will be password-protected
and Joo Hyeon-u may refuse to tell me the password.
I'm sure.
But...
you'll have to do whatever it takes to make him talk, understand?
You must bring back
the research data tonight no matter what.
Okay.
I'll make up for the wrong I've done with this tonight.
What's gotten into you?
I wanted some fresh air. Why?
Then you should go somewhere fun...
Were you dumped?
Where could I possibly go?
You're done with work, right?
Yes.
Then go somewhere with me.
Why did you want to come here?
It's your birthday next week.
I wanted to buy you a present now.
You could have waited until next week.
What's wrong with being early?
I realized that
I never gave you anything other than drugs.
Stop that.
But of all the clothes...
Don't stay at home all the time
and go hiking and traveling
with Dr. Yu.
You have a vitamin D deficiency.
Just avoid sunrise.
That's nice.
Hold on.
You totally look like a model.
You didn't know that before?
Everyone knows that.
You're slightly annoying,
but I agree.
Right, we need one for Dr. Yu.
Excuse me.
Where are the women's clothes?
Something bright and vivid.
You're lucky, you look good in anything.
Enjoy your new clothes, okay?
DR. YU RITA IS IN DANGER
-I'll go with you. -It's okay.
You go ahead. I'll be right there.
Dr. Yu.
Dr. Yu!
Dr. Park.
Are you okay?
-Did anything happen? -What's wrong?
I got a text that you were in danger.
A text?
-Let's go to my place for now. -Hold on.
I have something to ask you.
About Min Ga-yeon...
Hold on.
-Hello? -Hello, Dr. Park.
This is Joo In-ho.
It's been a while.
You...
What's going on?
It's Joo In-ho.
I like how you decorated your place.
But that's not the only thing I like.
You've made good progress in the research too.
Ji-sang.
Hyeon-u.
Ji-sang...
I'm sorry.
I gave him all of our data.
He said he would kill Dr. Yu otherwise.
Ji-sang.
You'll forgive me, won't you?
Joo In-ho.
Yes?
You can take all of our data.
Leave Hyeon-u alone.
He is quite famous in the academic world.
He used a nickname, so I didn't realize it until now.
Plus,
his research on VBT-01
is far more advanced than mine.
Joo In-ho.
I said leave Hyeon-u alone.
I'm sorry.
I...
I have jealousy issues.
Joo In-ho!
Hyeon-u.
Don't do this to me.
Hyeon-u.
I'm sorry I'm late, Hyeon-u.
Hyeon-u.
Hyeon-u!
I'm so sorry, Hyeon-u.
It's all my fault.
Wrap it up quickly.
My patience is running out.
Has the vice director been taken in?
I thought Joo In-ho was acting alone,
but I heard he was following your orders.
The price of success in the research seems to be our lives.
Make sure you take care of Yu Rita this time.
Dr. Park.
