I'm not into hunting,
but he kept hanging out in front of my house.
That's why I captured him.
Wait, I didn't kill him.
I just give him a little sedative.
Actually, not a little bit. I gave him a lot of it.
He will probably wake up after a few hours.
Why did you bring him to me?
He's after both of us.
Of course, I have to share the news.
Is that all?
I brought him here for a reason.
Please kill him,
Director Lee.
I have never killed anyone, infected or not.
I saw you in action last time,
and you seemed very experienced.
I'm not that experienced either.
Why don't you
take this chance to gain the experience yourself?
It's something you'd have to go through
at least once eventually.
Later, if the need arises.
Please take care of it for me this time.
And send me a photo afterward
so that I know for sure that it's been done.
It's not that I don't trust you.
I just really want to see him dead.
He wouldn't come back to life
or anything like that, right?
Anyway, I'll get going now.
I didn't mean to bother you like this. I'm sorry.
Would Director Lee really kill him?
I don't know.
It will take some time for the drugs to wear out.
Whether he kills him or not doesn't really matter.
If he kills him,
he'd be killing his henchman who's been with him for years.
If he doesn't kill him,
he'd be revealing who he really is to me.
That's quite a dilemma.
You're right.
That could be more annoying to him.
Then...
let's wait for the photo
he's supposed to send you, just for fun.
He probably won't kill him.
Why do you think that?
It would hurt his pride
to play along with my game.
Then I guess we can sleep peacefully tonight.
Kill him.
-But, sir... -Kill him.
Thank you for everything
over the years, sir.
J is like a brother to me.
-So? -I'll kill Park Ji-sang.
Then everything will be...
We've been together for 40 years.
Gi-seung, Do-seong, and Hak-jun were enough of a sacrifice.
Why?
Why the hell
do you guys have to be my weakness?
-I'm sorry. -I didn't save you
from the brink of death to be insulted like this.
If we fail
because of one little mistake,
it would mean that we spent
all those years together just to prepare ourselves to fail.
We will have
nothing left.
Why are you still awake?
You must be cold since your temperature is normal now.
It's bearable.
It's not too bad.
Do you want to sleep in the room?
What about you?
I'll take the bed. You can sleep on the floor.
There's plenty of room on the floor.
Forget it. Men and women must be segregated.
My goodness.
Were you born during the Joseon dynasty or what?
I feel like I'm being a such a nuisance to you.
Should I just go home?
What are you talking about?
-Forget it. -Gosh, you scared me.
Why are you getting so angry?
Stay here until I know for sure that it's safe.
All right.
I'll stay until you tell me that it's safe to go home.
Get some sleep now.
Can you...
stay with me just a bit longer?
I'm having a hard time falling asleep today.
Shall I sing you a lullaby or what?
No, there's no need for that.
Just...
Just stay by my side.
You don't have to say anything.
DIRECTOR LEE JAE-UK
Come in.
Good morning.
-Yes. -By the way,
you never sent me any photo last night.
I waited all night.
I didn't think you needed to see it.
Why not?
There is no need to see something so cruel.
I see. You thought it was too cruel for me to see.
Thank you for being considerate of my feelings.
Well, I'll just pretend that I saw it,
since I trust you.
Oh, right.
I need to do something today.
There may be a small commotion.
Please be understanding.
-Really? -Yes.
What will you do about the aftermath though?
The aftermath? I am trusting you to take care of it.
-Me? -Yes. You can't do it?
That's not what I'm saying.
Okay, just do it. I'll take care of the rest.
Please prepare the blood-drawing apparatus for me.
I'll need about four or five.
Dr. Park.
-Did you get permission-- -No.
I'm just going to doing it.
We'll take care of everything, so please don't worry.
If there's a ruckus like the last time...
I can't guarantee that there won't be one, but it will end quickly.
Very quickly.
JANG YU-JIN
This has nothing to do with you.
You shouldn't get dragged into it like last time. Wait outside.
Go on.
I'll be fine.
Stop them like last time.
Confiscate the blood samples.
If you do this again, there will be a problem.
Then let there be a problem.
I politely ask you
to hand over the blood samples.
Move out of the way. We're busy.
We can't do that.
Move before I count to five.
Otherwise,
you will be staring at the ceiling
in a hospital bed all day long.
I told you so.
Nurse Lee.
Please call for help. They look like they are in pain.
Which way are they headed?
Send our guys over there now.
How could this...
Dr. Jung!
Oh, hey.
What's up?
I have the results for the multiple myeloma patient, Lee Hyeon-jong.
Okay.
You tested the immunoglobulin as well, correct?
Yes.
By the way, what were you doing?
Nothing. Nothing at all.
You've been acting strange lately.
I feel like you're hiding something.
Gosh, why would I hide anything?
I don't keep any secrets from you.
You totally do!
Last year, when you had prostatitis for two weeks--
Hey, jeez.
Why are you bringing that up?
Anyway,
I'll be disappointed if you're keeping something from me.
I mean it.
I know that, of course.
What is going on now?
Dr. Jung, these are blood samples from Ward 21A.
Jeez, what are those jerks doing there?
Are we criminals or what?
I managed to keep half of the blood samples.
Take them to Hyeon-u.
I will. Thank you.
Will you be okay though?
You caused a total ruckus in Ward 21A.
He couldn't resolve the matter by being a gentleman.
Gosh, we should've done this from the start.
Back then, if it weren't for my uncle...
I know, right?
Then Seo Hye-ri wouldn't have been able to humiliate us like that.
As you already know, you must be careful with it.
Yes, I'll be very careful.
You too. Be extra careful, okay?
Well, you all seem to know something that I don't know.
I feel like I'm the only one out of the loop.
There's something, right?
I must be the only one who doesn't know!
My gosh.
I've never seen you entering a room without knocking first.
Please return
the blood samples.
My gosh, I'm sorry.
They're already in the machine.
It isn't something you can be so reckless...
It's not something that we can be reckless with?
Let's talk,
Dr. Park.
I never thought
that you'd do something so thoughtless and immature.
You shouldn't abuse your powers
as a carrier of the virus on humans like that.
I've always been a good fighter.
I don't need the powers I gained
from the infection.
You seem to have a flippant attitude these days.
I thought you were a thoughtful and serious person.
I had something to fear, which made me nervous.
That's probably why I came across like that.
But now,
I don't really fear anything.
Why the hell did you do this?
You're using the virus we have.
I was too curious to just sit still.
You're well aware
of what will happen if word gets out about it.
The word won't get out.
Those people you saw earlier will keep it confidential.
Besides, I don't want the word to get out because it won't do me any good.
We'll just examine it amongst ourselves.
Do you think that will change anything?
I'll at least be able to find out why the research is failing.
You sound very pessimistic.
I'm not being pessimistic.
I'm just telling you the truth.
It'll also give me an idea of what you can do.
If you don't like that... Shall I stop?
No, go ahead.
I would like your objective evaluation of my abilities.
Thank you.
DEATH CERTIFICATE GONG JA-BOK
EMPLOYEE PROFILE SEO HYE-RI
Ms. Seo's apartment is clean,
and her car is still in the parking lot.
From her closet and her dressing table,
we can tell that she packed up her stuff.
VICE DIRECTOR CHOI GYEONG-IN
But we can't find her whereabouts.
Her phone has been cut off too.
Stop the investigation for now.
I have another idea.
If you mean it and if it's the truth,
I hope you become like me.
Be unwavering regardless of any change or variable
and maintain your belief.
Turn that belief into action and stay loyal.
Dr. Min.
Hi, Su-yeon.
I have a favor to ask.
What is it?
I told you to get out.
You won't be able to view the results.
I did the test. Why can't I see the results?
You just can't. Absolutely not.
Even this little punk is ordering me around now.
Don't move.
-Get it. -Don't...
move.
You little...
Get out.
-I can't do that. -Whether we give it to you or not,
you can't take it with you anyway.
Yes, Director Lee.
Got it.
You should show it to your superiors first. How rude.
Hey. They really do exist, don't they?
They do, right?
You saw the results, so you must know the answer to that.
So, if you get injected with VBT-01,
you become a vampire, right?
I guess?
What we tested was in a vaccine form, so that probably won't happen.
By the way, it's really important that you keep this confidential.
This is huge.
Okay.
But if this virus really does exist,
do you think Dr. Park Ji-sang could be infected with it as well?
I can't stop suspecting him.
He can't be!
You're at it again.
I'm going to find out the answer myself at all costs.
Hey, you brat.
Why do you have to find that out?
Why are you getting all worked up?
I must say, the two of you are very suspicious!
-What's your problem? -After living with him for a few days...
Look at you. Are you that happy?
Living together?
Watch what you say.
You two are living together. How else would I describe it?
Something must've happened earlier.
I heard some noises.
Well, it does look like something happened.
Don't worry about it though.
Honey.
The drug I'm on must be very strong.
I keep having extreme mood swings.
I'm sorry.
It's okay. I understand.
I'm just happy that you're so much better now.
Thanks.
Get some rest while you're taking a break from the infusions.
Dad.
Hi, Su-yeon.
I wrote you a letter to cheer you up.
You did?
I didn't have any stationery, so I just wrote on this.
Dr. Min gave me some paper.
Here you go, Dad.
Wait.
Don't read it out loud, okay?
I'm sorry, Dad.
Honey.
Dad.
Are you okay, Su-yeon?
Su-yeon.
You gave Choi U-sik Stage Three of the vaccine, right?
Yes.
You'd be better tell me the truth.
What do you mean?
It's not the Stage Three vaccine that I know, is it?
I told you that you'd better tell me the truth.
I don't think I have any obligation to report to you.
Just because the director is fond of you,
it doesn't mean I have to be.
Don't you dare lay a finger on me ever again.
As you can see...
This is the result.
How could he do something like this?
Oh, right.
There's a patient by the name of Lee Na-jeong, right?
Yes, she's a kid.
She doesn't have anything.
She's clean.
I guess they haven't done anything to her yet since she's a child.
It looks like the vaccine is in blood serum.
Is that combination possible?
I mean, medically speaking.
VBT-01 makes it possible.
What's the matter?
I'd like to know about the new Stage Three vaccine given to patients in Ward 21A.
What do you want to know?
It seems to be working differently from what I know.
That's right.
It's much more effective than the version you know.
Do you mind telling me more about it?
To put it simply,
it's a hybrid of an immune serum and the vaccine.
As we expected,
the serum maximizes the level of immunity.
But the form and ratio of the vaccine seem unusual.
I think it's a live vaccine,
but still...
It looks like VBT-01's subcultures have been minimized.
What exactly does that mean?
This isn't a vaccine.
It's pretty much an infection.
If it's like an infection...
If the serum and the vaccine are thrown off balance,
those who got it can be infected immediately.
And those who are infected can infect others.
That's right.
But that balance itself is very problematic.
It's too unstable.
What's with that look?
It means we can achieve our goal sooner.
Wasn't minimizing the subcultures our last resort?
If the last resort is the best option,
then there's no need to wait.
Is something wrong?
No, I was just curious.
You've been asking a lot of questions lately.
I'm sorry.
Sir.
I'd like to ask you once again
to exclude Na-jeong from the experiment for the time being.
All right, I will.
Ga-yeon.
I hope you won't end up becoming my weakness.
If that happens, you'd be my most fatal weakness.
I'll keep that in mind.
-Is everyone there? -Yes, sir.
Tell all of them
to get the physical condition reforming injection by tomorrow.
Got it, sir.
Hey!
Who gave you permission to step out whenever you want?
I'm sorry. I'm really sorry.
The orders got messed up, and it's a disaster here.
I'm sorry. I'll get right back to work.
Don't be all talk--
I'll make sure it won't happen again.
Gosh, seriously...
You should've at least told me that you were stepping out.
I'm sorry.
I know that Seong-gyun can be intimidating,
but I'm your direct supervisor. You can open up to me, you know.
-Okay. -All right, then.
Get changed and head over to the ICU.
Okay.
I haven't taken an evening stroll in a while.
My, I feel so refreshed.
You had a long day today.
You had to run around all day.
And we found out that the situation
is a lot more serious than we expected.
What is with you?
Why do you keep smiling like that?
I suddenly remembered something.
When I first got here...
The California girl make-up you put on...
Goodness, why are you bringing that up out of the blue?
Stop it.
All right.
I told you to stop it!
Okay.
Gosh.
Honey!
Find me!
Darling, I can't find you.
Where are you?
I'm here!
-You're so mischievous. -Come on.
All I could see was flowers. That's why I couldn't find you.
Gosh, stop it.
What the hell was that about?
Shall we try it too? Just for fun?
Forget it. Don't even dream.
Let's try it just once. Just for fun.
Fun or not, I don't want to do it. I can't do it.
I told you not to...
Find me!
-I can see you right there. -Gosh, come on!
Like that guy, you should've pretended you couldn't see me.
I couldn't pretend I didn't notice you.
I mean, a flower was talking.
Oh, my gosh.
He must be losing his mind. Goodness.
What will you do about this? My hand curled up because you made me cringe.
I'll fix it for you.
I'll let it go if it's good now.
No, it'll take a while.
CANCER INFORMATION CENTER
Delete all security camera footage. Right now.
Make sure the guards keep their lips sealed.
Do you have a hormonal imbalance?
Why do you shed so much hair?
All women with long hair are like that.
Have you never dated anyone with long hair?
-No. -What about someone with short hair?
-No, I haven't. -Then mid-length hair?
No, never.
What? Does that mean you've never dated anyone before?
When those with the infection feel love,
the pituitary gland hypersecretes phenylethylamine and oxytocin,
which is bad for us.
It also makes us lose our grip on our emotions
and desire for blood.
Oh, I see.
But when you're right next to me
and when you held my hand earlier...
Were you okay?
I mean, you seemed fine.
I guess I have no effect on you.
Right.
You probably just feel...
things like loyalty, friendship, and comradeship when you're with me.
There are exceptions.
I didn't know this before, but I learned recently
that even when the pituitary gland is overly stimulated,
I'm not affected by it if another part is stimulated even more.
Another part? Where?
Here.
For me, it's right here.
Allow me...
to do a final test.
You're shaking.
I think I'll be fine,
even going forward.
I really can't believe that I'm here with you.
I feel the same way.
Talk about bad timing.
Hey.
What?
I'm sorry.
I had no choice.
What happened?
It's okay.
It makes no sense.
He had no reason to take his own life.
It makes no sense at all.
Are you in charge here?
Yes.
We didn't find any suicide note, but it looks like he took his own life.
I'm telling you. He'd never do that!
He was always so cheerful.
We'll contact you if we find anything unusual.
Are you sure nothing happened?
Yes.
He gave me a big smile when I last saw him.
POLICE LINE DO NOT CROSS
Something is wrong, right?
I'm sensing that one of the infected was there.
I caught a subtle whiff.
Are you saying
one of them came all the way here and killed Byeong-su?
Why would they kill him?
That I don't know.
But if someone who has no association with the infected
was killed by one,
there can be only one reason.
He probably
found out about their secret by accident.
Gosh, who could've done something like that?
One thing is for certain.
He left such a subtle trace,
so he must have taken the physical condition reforming substance.
They're all over the place. How are we going to find out who did it?
But the director is the only other one with the infection at the hospital.
It could be an outsider.
It's not hard to sneak into the hospital.
Whether it's an outsider or not,
people are exposed to serious danger.
Even just ordinary people.
I agree.
If we don't stop them,
we may end up with more innocent victims.
The physical condition reforming substance...
What about it?
Some of the infected must've been injected with the substance.
I was wondering if there's a way to distinguish them from the other ones.
Distinguish them?
The formula may react when it's exposed
to certain substances.
You're right.
Why didn't I think of that?
How could this have happened?
Suicide?
I'm sorry, Mr. Chairman.
I'll make sure there are no more incidents like this.
Taemin cannot have even the slightest flaw.
I understand.
What about the police and reporters?
I have spoken to Commissioner Lee,
and we've already stopped the media.
Good work.
You can leave now.
Director Lee, can we talk for a few minutes?
I'm sorry, but I have a surgery to get to.
I see. I'll wait, then.
Jack rabbit
-My gosh, you've gained some weight, -Where are you going now?
and your blood pressure has improved too.
We should be able to operate sometime next week if you keep this up.
Gosh, I don't want an operation!
The surgery will help you recover fast, so don't whine.
Whatever. You're always picking on me.
Whatever.
I should probably wait until next week, but I want to say it now.
Please take good care of Na-jeong.
You sound like her sister or something.
She's like a little sister to me.
I'll take good care of her until her surgery.
Okay.
Take good care of your other patients too.
Of course.
Jumping jumping everywhere
Where are you going now?
What are you looking at?
I'm very disappointed.
What disappointed you?
The sloppy combination of the vaccine and the immune serum, for one.
More importantly, I don't get why such a wise man like you
decided to kill the goose that lays the golden eggs.
Are you talking about the minimized subcultures?
Yes, you're well aware.
And you pulled out that card already?
I decided that this would be the right time.
I must say, it's truly unfortunate that you made such a decision.
The damage is already done, so good luck.
Although I feel as if I'm watching a team losing 20 to 1,
down to the last strike in the ninth inning.
Dr. Park.
Yes.
I guess you really have no fear now.
That's right.
I told you that wasn't necessary.
It would have been nice if your parents had lived longer.
Then they would have
taught you how to fear and be polite.
I definitely know how to fear and be polite,
but I don't waste that knowledge on those who don't deserve it.
Please, Director Lee.
It's fine even if it's not complete.
Can I just get the drug as soon as possible?
No, it may cause worse problems.
That's fine.
It'll be better than what I'm experiencing now.
No, Mr. Chairman.
Why can't I get it? I'm telling you that I want it!
I'm paying for the research, so do as I say!
Mr. Chairman.
Please calm down.
Sorry about that.
I got too worked up.
I told you that we're almost there.
Why won't you listen to me?
You must not let your anxiety force us to make a mistake.
Please remember that, Mr. Chairman.
Dr. Park!
My gosh, Rita.
Goodness, I haven't seen you in so long.
I know, right? What brings you here at this hour?
I stopped by to see Dr. Park Do-min.
You can't leave like this.
You should've come to see me or the vice director.
I know how busy both of you are, so I didn't want to bother you.
But still.
I've actually been wanting to ask you something about my uncle.
Oh, really?
Did the vice director tell you everything?
-About what? -What?
She didn't tell you?
If the chairman asks you for the vaccine,
refuse his request and let me know right away.
Got it, sir.
But...
I know that it's unstable,
but we've given it to the patients in Ward 21A.
The chairman must not be harmed.
If he has an adverse reaction to the incomplete vaccine,
we may be unable to continue with our research.
I understand, sir.
The files you gave me...
Especially the ones for VTH-16.
-Yes. -You're really impressive.
How did you engineer an antibody like that?
Hyeon-u worked very hard for that.
I see.
But as you know, that immune antibody can be very dangerous.
The virus isn't the only thing it kills. It destroys normal cells too.
We've tested it on the blood from the patients in Ward 21A,
and it was fatal on them as well.
We had to scrap the research because we couldn't figure out what caused it.
Figuring that out won't be easy.
It may be impossible.
I've gone through those files many times with hopes of finding the answer,
but each attempt was fruitless.
But I will continue with this.
I'll be persistent.
Sure. That sounds good.
Also, how is it going with the director?
It's going well.
I'm glad to hear that.
But don't you think you need something
that can provoke him more?
I think you're right.
Why do you look so tired lately, Aunt Gyeong-in?
I have a lot on my mind.
I have to wrap up the Hanju Hotel acquisition too.
Oh, right.
Has Uncle Seok-ju gotten a checkup yet?
Well...
He told me not to tell you,
but yes. He got it done.
When?
He didn't want to worry anyone at our hospital,
so he got it done at Seongwon Hospital last week.
What were the results like?
His blood sugar level went up a little,
but he's fine otherwise.
Oh, really? That's a relief.
His hands have been shaking, so I was worried.
They said it's likely caused by his blood sugar level.
I see.
Act like you don't know about it, okay?
If he finds out, he won't trust me anymore.
Okay, I won't say anything.
DIRECTOR LEE JAE-UK
Dr. Yu.
-Yes? -Is something wrong?
No. You should get back to work.
I'm sorry.
I should have told you too.
The vice director asked me, saying that it could
pose a problem at the stockholders' meeting.
She said she needs to be prepared, so I told her.
I thought she'd tell you,
but I guess she didn't want to worry you.
I see.
That's probably why she didn't tell me.
But, Doctor.
Is my uncle's illness
really incurable in his current state?
Currently, yes.
I have one more question.
Is it hereditary? Could I get it too?
I'd say there's a 50-50 chance.
Your father was fine,
but that doesn't mean you are safe.
I enjoyed your work.
Why don't we meet up and have a discussion about it?
I thought it was a real bomb.
Oh, wow.
You're coming on strong already.
It's a ruthless antibody
that eats up anything it comes across.
Does it have a name?
Vampire to Human.
VTH Number 16.
What a meaningful name.
Anyway, why did you want me to see it?
-I thought you'd need it. -Me?
Yes.
Hypothetically,
when an incurable virus spreads in a region,
you can bomb that place.
I wanted you to see it just in case you might need a bomb later on.
Well...
I don't think I'll ever need it.
Don't you think it's too early to jump to that conclusion?
I'll give you more time.
I miss how we treated each other when we first met.
Both of us were very polite,
and we respected each other.
I prefer how things are now.
Also, you keep thinking that your research is perfect,
but it really isn't.
So, why...
Why did you split up?
If you had worked on the research with Dr. Jung and your friends,
you would've succeeded a long time ago.
Oh, that must be it.
You probably couldn't bring yourself
to ask them to work with you
because of your pride.
I can totally do it on my own.
Set your pride aside just once
and ask for help.
Then I'll help you if no one else wants to do it.
Why?
Does it hurt your pride to even ask me?
Or...
is it not about your pride?
No way. Was it because your mentor and your friends
never accepted you?
Is that it?
If that's not the reason either...
Let's see.
Everyone said that you shouldn't do it,
but because you're stubborn and reckless...
You pushed ahead with it all by yourself, didn't you?
-Shut up. -My gosh.
How scary.
Don't you dare run your mouth if you don't know anything.
I'm talking because I know.
I made the right decision.
Everyone else was too afraid to even try.
All of my efforts almost went down the drain because of their fear.
Wasn't it your greed that washed away all the conscientious efforts
made by your mentor and friends?
They were completely wrong and cowardly.
They never deserved this to begin with.
I see.
They were wrong, cowardly, and unqualified.
That's why you hated them so much.
Don't talk to me like that.
So, I guess that's why you decided to take all the credit for it.
I told you not to talk to me like that!
Is that why you killed them? Both of my parents!
Yes, I killed them!
I was the one who gave the order to kill them. It was my doing!
You didn't forget everything I told you, right?
Show me anything, whatever it is.
Let me enjoy it first.
You enjoy hurting patients.
And now, you've killed--
This is the last time
I'll be nice to you just because you're the director's favorite.
I will...
kill you very soon.
I can't bite a dog
just because it bit me first.
