I came by several times.
How come you never noticed?
I did.
Who are you?
You...
Leave her alone.
Who are you?
Your virus research...
Stop it.
If you don't listen to me,
and if I have to come see you again,
I won't go easy on you.
If you do that again,
you're...
You're dead.
Me?
You're all grown up now.
Park Ji-sang.
Dr. Yu!
Okay.
It's all right as long as you're okay.
Is something wrong, Dr. Jung?
Nothing.
I'll explain later.
Get some rest, Dr. Choi.
This research,
please stop it.
It could be dangerous.
Did everything go smoothly?
-Yes, sir. -Yes, sir.
Be extra careful and don't run into Park Ji-sang.
It could cause a problem if you meet him too soon.
We'll be careful.
I don't know about Dr. Jung Ji-tae,
but don't be rough with Dr. Yu Rita.
Just make her scared.
Okay, sir.
Dr. Yu.
Are you okay?
Let's get you to the hospital.
You may have a fracture or a concussion.
I'm fine.
I know my body.
Still...
Who was that man?
He's infected too, isn't he?
You know each other, don't you?
Why did that infected man who knows you
keep coming to my place and threatening me?
What is this about?
Please tell me everything about you.
Everything you haven't told me.
You don't need to know.
You're the one who put me in danger.
And you're saying I don't need to know?
Should I remain clueless and continue to be attacked?
I'm serious.
I don't want you to have
anything to do with the virus
or those infected anymore.
It's not that I don't want to tell you my secrets.
It's because you may fall into greater danger.
I don't care.
Now that I've experienced it, it doesn't scare me.
Please, do as I ask!
That jerk
is infected and capable of killing people without a second thought.
You were lucky today.
Who did that jerk kill
without giving it a second thought?
My mother.
Please tell me everything.
I can handle it.
Please.
I'm telling you,
I'm doing this for you.
If it's really for me,
give me a chance.
Give me a chance to help the boy who saved me.
Please let me be a decent human being.
Me saving you
wasn't such a great deal that you need to give up everything...
just to repay me.
Perhaps not to me, but to Yu Chae-eun,
it was like a miracle.
Please.
Let's leave this place for now.
It's too dangerous to stay here alone.
Didn't you know of the instructions about not making Na-jeong a subject?
Of course, I knew.
You're mistaken.
Her IV flow was too quick,
so I was checking it and noticed how cute she was.
Please don't get the wrong idea.
I'll be more careful from now on.
She is the only child patient with advanced cancer.
It's a waste not to do anything with her.
Leave her for now.
It won't be too late if we start later.
Okay, Director Lee.
And starting tomorrow,
administer the new stage-three vaccine.
We're not done testing stage-three vaccine yet.
If we administer it too soon, it may cause unexpected side effects.
The previous side effects may also return.
We'll have to handle whatever side effects appear.
This is a chance
for a very smart problem-solver to step up.
I'll get on it as instructed.
You're about to see...
everything you wanted to know.
Are you sure about this?
It may be like opening Pandora's box.
I want to see
everything in that box.
Okay.
Let's begin.
I'm going to catch you.
If mommy catches you, I'll kiss you 50 million times!
You got on a horse? I'll still get you.
I'll come after you.
Hurry!
Do you have a date today?
Come on, put that away.
Why? You look so handsome.
Wow, you're so handsome.
If you're watching this,
that means something very bad has happened.
I wish you would never need to watch this.
But if you are,
listen to what I'm about to say.
What?
He didn't have a high frequency and an odor?
No.
His temperature and pulse were normal too.
What about 20 years ago?
He had them back then.
Then how did you detect him this time?
I just went in because I felt someone was there.
I didn't know he was infected.
-Then, could he be... -Yes. You're right.
This changes the infected person's physical condition
and makes it similar to a human's.
I found it by chance and produced it.
It's to prevent myself from being found by other infected people.
If what the director said is true, shouldn't he be the only one using it?
-If he discovered it by chance-- -I'm not sure about that.
We need to find out if he's the only one who uses it.
Also, he said it was to prevent himself from being found by other infected people.
But the one who killed your parents tracks down others.
So, why would he...
Your abilities are endless.
Just like you used those abilities to save that girl,
you will save yourself.
And one day, you'll save many people.
I'm sorry
I can't be with you.
I love you,
my dear son,
Park Ji-sang.
It'll be fine as long as you turn off the cooling feature.
So this is where you sleep.
I thought...
That I'd sleep in a coffin?
That's one question off my list.
But it's so hard.
Just think that you're on a stone bed.
Dr. Park.
Yes?
I may be out of line,
but may I say something?
You've grown to be a much better person
than your mother had hoped.
I'll ask my questions over time.
You should rest tonight.
Good night.
Park Ji-sang.
Rise and shine!
Get up! Rise and shine!
What is that smell?
Wait.
Is this...
Come have breakfast.
Ta-da.
How long has it been since we last had a home-cooked meal?
There was not much stuff in the fridge, so it's not that great.
Please enjoy it.
I know you can't taste anything, but have some.
No, thanks.
I can tell that it's bad just from the looks of it.
Don't eat it then.
You shouldn't judge food by its looks.
Also, what's the point of looking pretty?
Exactly. As long as it tastes good.
Let me try it first.
Does it taste bad?
No, it's just...
I can taste each ingredient separately, but at the same time--
If it tastes gross, just say it.
Of all the terms out there, must you say it's gross?
It's okay. It's edible.
Is it that bad?
It looks good, but it's pretty salty.
Gosh.
It looks very good. Too bad it's salty.
It's so salty.
Good morning.
Yes.
It's a good morning for both humans and those infected.
That's because they both breathe air.
Director Lee.
Yes?
You must have something to say.
I still haven't changed my mind about not drinking blood.
However...
I do want to experience having a body
similar to a human's.
It wouldn't hurt to try it at least once.
Stop by tonight. I'll give you some.
Thank you.
Don't mention it.
What happened?
You and Dr. Jung both got attacked.
-Dr. Jung was attacked too? -Yes.
He said some guy blocked his way and told him to stop the virus research.
Luckily, he wasn't badly hurt.
You're okay, right?
Yes.
Do you think it could be
a pharmaceutical company's conspiracy like in movies--
No, I don't think it's like that.
By the way, Rita.
I know this isn't the right time to ask this, but--
Do you want to get a facial?
No.
-If you know Hyeon-u's phone number-- -My goodness.
You two were blatantly flirting,
but you still weren't able to get his number?
-Sorry. -Gosh.
I don't know either. I only know his e-mail address.
Find out yourself.
I'm busy. Bye.
Why, that brat!
I told you, didn't I?
If we hide anything from each other, our joint research is over.
What's the matter?
Someone came up to me last night.
He lifted me up by my neck and threw me to the ground.
And then he warned me to stop the virus research.
Something is going on, isn't it?
Do you remember what he looked like?
-Height? Any facial features? -Do you want a sketch?
I'm sorry.
At first, you told me
that this research was dangerous and that I should stop.
But a couple of days later,
you took it back and wanted to come on board.
I had no doubts back then,
but now I suspect that you had an ulterior motive.
No, I didn't.
My goal was to learn about the research.
Then why did this happen? Why?
Tell me why this research is dangerous and why I was attacked.
Explain to the best of your abilities.
I was attacked as well.
You too?
Yes.
I know this is an important issue,
but don't we all have rounds to make?
Let's get together tonight and talk about it.
That sounds good.
What I'm about to tell you must be kept between us.
You must take it to your grave.
I understand, Director Yu.
I won't tell anyone no matter what.
It's a shame.
Don't you agree that it's very normal?
The vice director should oversee hospital operations.
I wasn't bluffing before.
I'll have no choice but to tell Chairman Yu.
Go ahead and tell him then.
That's everything I have to say.
The man who attacked Dr. Jung must be infected too, right?
If he could lift Dr. Jung by the neck, probably yes.
Then he must be the one who has chasing you all these years.
That's very likely.
But I still don't get it.
Why didn't they attack you? Why did they attack me and Dr. Jung?
Because the two of you know the most about the infected.
The top priority for the infected is keeping their identity a secret.
I'm curious about something else too.
What?
How did you know that infected guy would attack me at my home?
Oh, that?
You said you noticed.
How did you notice?
Well, I...
You said you felt like someone kept breaking into your apartment.
Yes.
Ever since then,
I've been going
to your apartment every night.
What?
Then, every night, you'd first go home...
-I need to go out. -Again? Where are you going?
Are you hiding a girlfriend somewhere?
...and then come to my apartment?
Well, I guess you can say that.
Well, then...
It's not like you noticed him with some special ability
but you just staked out my place without a specific plan?
Oh, my gosh. Why do I find this so funny?
What are you, a stalker?
My goodness.
How could you do that?
Oh, my goodness.
I heard everything from Director Lee.
Starting tomorrow,
work at Taemin Insurance.
Why aren't you answering me?
I can't do that.
What did you just say?
-How dare you-- -I'm not daring anything.
I'm requesting the proper authority for my position.
You.
After all I've done for you.
You ungrateful...
Listen to it when you have time.
Our history
is recorded there.
This isn't just any drug.
It's a groundbreaking drug developed over many years.
I'm sure it is.
Thank you.
I don't know if I'm imagining it,
but I feel like he got better in just two days.
You're not imagining it.
I can see it too.
Thank you so much.
Thank you.
Don't worry.
Did you hurt your head?
Yes, I got drunk and fell.
I see.
I'm glad it wasn't any worse.
-I'll get going. -Dr. Jung.
About your father's research...
What if our hospital launched it officially?
Of course,
you will be in charge of the project.
No, that's fine.
I just think it deserves more attention.
You read it, so you must know.
It shouldn't be introduced to the world.
What if we bring to light with utmost care
and keep it under control?
When Dr. Jung Han-su was conducting his research,
I'm sure the conditions were subpar at best.
But it's different now,
especially at our hospital.
I'll pretend I didn't hear that.
Also, don't concern yourself with my father's research.
Just keep doing what you're doing with Ward 21A.
The surgery went well,
so don't worry.
Goodness.
How are you
all so bad at lying?
Lying?
You're all just too nice.
You can't lie at all.
I...
I already knew when I was admitted here.
I knew I had no hope.
It's been such a pain to pretend to have no idea.
Look over there.
Here come bad liars.
Hello.
Please.
Please just let me go in peace.
What are you talking about?
-The surgery went well-- -It's okay, Rita.
She knows everything.
So, let's do what she wants.
My goodness.
Your little brother here will take good care of you, Sister.
I like hearing that,
"little brother."
Why are you crying?
I...
I'm still with you.
-What's her name? -Anne.
Anne?
This is Tong-tong.
Hi, Tong-tong.
How childish, playing with plushies. How old are you?
-Me? -No, not you.
-You. -Me?
I'm older than you.
I'm 25.
You shouldn't be rude to someone older.
I don't know things like that.
If you don't know that, you're stupid.
-You're a bad kid then. -What?
You brat!
I'll do what I want! What will you do about it?
Then may I speak rudely to you too?
-What? -"Hey, Lee Na-jeong!" Like that.
-You can't do that. -If you can, why can't I?
Right, why can't she?
Hi, Na-jeong.
-Hi. -Hello.
-Yu-jin. -Yes?
-Have you eaten? -Yes.
What did you have?
I had porridge, not-salty beef, and not-salty kimchi.
Good job.
What a cute plushy.
May I see it?
Please take good care of Sister Sylvia.
Of course, I will. I'll make sure she is comfortable.
By the way, did you take care of the vice director?
Well, Director Lee.
Yes?
I'm letting her stay at the hospital,
and I'm letting her keep her position.
She is very capable.
It'd be a waste to send her away.
But Chairman Yu.
She keeps interfering.
I know.
However, she was always caught.
She won't be so reckless anymore.
Please be patient and understanding.
The vice director is one thing,
but Dr. Yu Rita is crossing the line more and more.
Yes, I know.
I'm very sorry about that.
Please speak to her.
No, please give her a stern warning.
Please understand that if she keeps it up,
I can't just sit back and watch.
I'm sorry to bother you. I'll just drink water and go.
It's okay. Take your time.
Thank you.
-Dr. Yu. -Yes?
I don't know if I should say this,
but you seem to be the closest to Dr. Park Ji-sang, so...
It's about his health.
During the last procedure,
his hand touched mine briefly,
and it was incredibly cold.
Don't your hands and feet get cold at times?
Mine do.
It wasn't like that.
-It felt like a slab of ice-- -He seems fine, so I'm sure he is.
And my arm grazed against his during surgery once as well,
and he wasn't cold.
I see.
I understand. That's good then.
I'm sorry. I was out of line again.
Don't be so sensitive.
If you're done with water, go on.
Okay.
He should be more careful.
Why is he going around touching everyone?
I heard you were in surgery, so I waited for you.
Do you have something urgent to tell me?
I'll cut to the chase.
Don't cause any more trouble,
and don't hang around people who cause trouble.
Don't you really know who's causing the real trouble?
I'll be the judge of that.
Whether small or big, don't cause more trouble.
No.
I will keep doing this until the truth is exposed.
-Rita! -I won't watch Taemin fall.
I know you've done well, but Dad founded it.
-My dad's soul is in Taemin. -I gave my all too!
As much as your dad!
How could you think I would ruin Taemin?
Anyway, this is my final warning.
Watch yourself.
Listen to it when you have time.
Our history
is recorded there.
Please give it to me!
I'm sorry, but that's impossible.
Give me Jang Yu-jin's file!
I'm sorry.
Please give it to me!
You're giving us a hard time.
Please give it to me!
I'm sorry.
Give it to me, or I'll lie down on the floor.
-Please don't-- -Come on! Give it!
-Give it! -Call security.
Give it to me!
Give it to me already!
Thanks.
I saw what you did by chance while I was walking by.
Why did you do that?
I always do that.
That's why I got fired from every hospital.
Gosh, I wanted to be good at Taemin.
Dr. Park.
Have you decided what to tell Dr. Jung?
Yes.
You won't tell him the truth, will you?
I shouldn't, right?
You've shared the research and some of the secrets.
You won't be able to hide your infection from him forever.
That's true.
But, with more people knowing, I'll be exposed to greater danger.
By the way,
can we stop by my place after the meeting?
Why?
You said I need to stay with you for a few days.
I want to pack a few things.
Okay, now tell me.
Who attacked me and Dr. Yu?
Why did they attack us?
First,
the one who attacked Dr. Yu
is probably one of those who stole our research.
-"Those stole the research"? -Yes.
We're not the only ones
who know about the virus research.
I don't know when, but it was leaked.
I think someone else is doing the same research.
Is the guy who attacked Dr. Jung
working with the one who attacked Dr. Yu?
That's my guess.
I was attacked before too.
I was warned not to continue the virus research as well.
Is that everything you know?
Yes.
Someone wants to conduct the research exclusively,
and that's why we're being attacked.
That's all I know.
If you're hiding anything else,
our joint research
is really over.
I understand.
What should we do now?
Let's put a hold on the research for now.
I would like to look into who is behind this.
The guy who attacked me was no joke.
He seemed like a professional killer.
I'm not exaggerating.
What did you use on the chairman?
Pardon?
Whatever that was,
I praise your excellent survival skills.
I'm not sure what you're talking about, but thank you.
I think...
I underestimated you.
I'm not a difficult person.
There's no need to nervous with me.
Are you moving abroad?
It's just a few days. Why do you need so much?
You have no idea how much women need.
I understand that you need clothes and makeup,
but why do you need figurines?
They're my babies. They're a part of me.
You don't know anything.
Why do you need your slippers?
I can't wear other people's slippers. It's just uncomfortable.
Fine, take it all.
What else is there?
That's right. My pillow.
A pillow?
Sure.
Do you realize what a nuisance you are?
You don't have an air purifier, do you?
The air quality in this area isn't very good.
By the way, Dr. Park, that painting...
Did you paint it yourself?
Yes.
It's nice.
Did you paint it while watching the sunrise?
No.
I've never seen a sunrise.
What?
Watching a sunrise could be very dangerous to the infected.
It could even kill us.
I see.
You've really never seen a sunrise?
No.
That's why I painted it.
-Go to sleep. -Are you going out?
Yes. I need to go somewhere.
Can you pick up some ice cream?
-What flavor? -Honeydew.
Honeydew?
I do want to experience having a body
similar to a human's.
Why did he suddenly decide...
Here are two shots and they are a month's supply.
Let me know if you need more.
Thank you.
If I take this,
I'll become the second infected person
to ever have the physical condition of a normal human.
I'll be second only to you.
That's correct.
Oh, I'm not giving this to you for free.
Later on, I might ask you for a little help.
Sure.
Anyway, it's an honor.
I'm the only one other than you, correct?
The only other infected person to take this drug.
Yes.
But...
you need to know one thing.
Twenty years ago, when I was developing this drug,
my lab was found.
I had to make a quick escape,
so I inadvertently left some of this drug behind.
The infected who were chasing me
may have this drug as well.
Of course,
I hope that is not the case.
I see.
I hope for the same.
It was going well,
but he got out of it.
He escaped and left the drug behind?
So, he left the door open
to the possibility of others using it.
Darn it, this is crazy.
I got two,
so analyze one of them.
Will you take the other one?
I wasn't planning to when I got it, but...
Yes, don't do it. It may be dangerous.
But...
I want to know how it feels,
what it's like to have the pulse rate and the body temperature of a human
even just for a few days.
It would be very weird, right?
But I would like to feel
what it's like just once.
Okay.
If you want to take it, go on and take it.
Okay.
I'll try it just once.
Dr. Yu is asleep, right?
She shouldn't know about this.
This is the sound coming from your room.
DETECTING SOUND
She's sleeping.
But...
it will probably hurt a lot, right?
How badly could it hurt?
Temperature, 36.5 degrees.
Pulse rate, 67.
Blood pressure, 122 over 79.
Everything is normal.
Wow, this is insane.
Awesome.
Your body temperature is 36.5 degrees?
Yes.
Are you okay?
Your body can't be that warm.
Right.
Even the infected catch the flu at times.
We get fevers too.
I feel fine though.
I guess even VBT-01 is no match for influenza.
Are you really okay?
I said I'm fine.
You're making me worry.
-Dr. Yu. -Yes?
My heartbeat
feels like a human's today, right?
It really does.
How about here?
That's incredible.
You should catch a flu
every day.
When I was little,
it was my wish
to become a human whose heart beats like this.
Is it still your wish?
Why?
When I was young,
I didn't want to be a monster.
I hated having to live apart from people,
not being able to taste anything,
and being different from everyone.
I hated it all.
That's understandable.
You were so young.
I haven't changed much
since then.
I still want to become human.
You might not have thought it through.
Apart from a few inconveniences, being infected seems to...
come with its perks.
An average person would be willing to put up with
that much inconvenience and stress if he or she can become infected.
The desire
to live a long life without getting sick is the strongest desire of all.
Your virus research...
Stop it.
If you don't listen and I have to come see you again,
I won't be as nice.
Fine, let's try it.
CHIEF JUNG JI-TAE
Good.
Dr. Jung.
Are you continuing the research?
What if something happens again?
Did you think that little incident would scare me off?
Yes?
Dr. Jung Ji-tae restarted his research in his lab.
Did you think I was bluffing?
Yes.
I heard you weren't the same little kid anymore.
I don't know about that. You seem the same to me.
If you want to come at me again,
come prepared to kill me.
Where is he?
I'll blow your head off!
Dr. Jung!
What a great timing.
Dr. Jung!
Gosh.
Gosh, my jaw.
I think I dislocated my jaw.
I don't think it's that bad.
Did you catch him?
No, I lost him.
He fights
a little better than I do.
Gosh.
I thought you would be a good fighter.
Our little plan was useless.
It's okay, I was able to confirm who he was.
-Do you know him? -Yes.
He's the guy I saw a long time ago.
If I take this,
I'll become the second infected person
to ever have the physical condition of a normal human.
I'll be second only to you.
That's correct.
Didn't you know Dr. Jung personally?
I've seen him from afar, but we've never met personally.
It's time to put things together
to find the last piece of the puzzle.
Director Lee.
I discovered something strange
after taking the drug last night.
I would like to talk to you in person.
Let's talk in the conference room.
May I ask what you're doing?
If the guys who attacked you and Dr. Yu
are affiliated with Director Lee...
Why?
Did you think I'll keep losing to Director Lee?
Hey, what are you doing?
Will you just watch Ward 21A?
I don't want the injection!
I came to see what new side effects surfaced.
I hope you'll be like me.
