Open the door, you aliens!
Please find my brother.
Your brother went missing while looking into this case.
It happened to all other victims too. Headaches and nosebleed.
It happened to Kim Nan Hee too. Headaches and nosebleeds.
No!
He must've been talking about this blue bug.
- Bluebird is the culprit. - Bluebird is the culprit.
Dad.
What is this?
This is it. The reason they all died.
Who are you?
Catch him. Hurry!
Geunrin Park at 2pm. Come alone.
Why are you hanging out with her?
That girl, Jeong Yeon, is an alien.
- Where is Beom Gyun? - Why are you asking me?
- You should ask that alien. - Aliens don't exist!
Memory Access. I'll check Park Jin Gyu's memories.
He doesn't remember that part.
This is proof that Human B is messing with people's memories.
We must not let Bluebird slip away.
You're really almost there, Joon Hyeok!
What's wrong with this? Gosh!
I'm terrified to death...
that those horrible memories that I have forgotten about...
- might come back. - It's here. Bluebird is here.
He was giving memories back to them.
Until when will you let him fool us like this?
I need to meet Bluebird.
Detective Kim Joon Hyeok, why are you trying to find me?
Bluebird?
Is it you? Where are you right now?
I'll meet you there. I'll come now.
Please don't do this to me, Beom Gyun.
I need you, Beom Gyun.
So please stop this and stay by my side.
Woo Jin. It's me, Beom Gyun.
Kim Beom Gyun.

(Crime Control Monitoring)
Who told you to take a photo of me?
What's your problem? Give it back.
Excuse me, what are you doing now?
Seriously.
(Handam University of Science and Technology)
This is where it all began.
This is the place.
(Handam University of Science and Technology)
(So Yoon, I miss you so much.)
It wasn't a suicide!
(Rest in Peace)
Someone killed them. I'm saying they were murdered.
- Who are you? - Someone was controlling them.
I'm under surveillance too!
We must catch the culprit. The killer must be at this school.
- Please hear me out. - For goodness' sake.
Please listen to me. Please help me.
Please don't take photos of me.
- Get lost. - Don't take any photos.
- Please don't take photos of me. - Leave. Get out.
- Get out! - Please leave.
Stop taking photos!
- Who's this guy now? - Who is he?
- What's he doing? - Gosh, I'm speechless.
You're right. There's a culprit behind all of this.
The culprit is...
an alien. An alien killed all of those guys.
- An alien? - Get lost!
- What on earth are they doing? - Get out of there.
- Excuse me! - Can you please leave?
- Come with me. - Get out!
- Gosh, what was that about? - Seriously.
- What's your name? - Park Min Young.
I'm Beom Gyun, Kim Beom Gyun.
(Part 1: BETA Project)
I asked you where he is.
Why are you asking me? You should ask that alien.
- Are you feeling all right? - I'm not crazy!
Aren't you the one who's crazy?
The students at your school died because of that alien.
Do you know where he is or not?
I'm telling you that alien knows.
You. I'm asking if you know. Just answer my question.
She's the one who should know the most.
She's not the kind of person you think she is.
Beom Gyun must've been very stressed out because of you.
You've been totally brainwashed.
- Stop talking nonsense. - You don't have time for this.
Beom Gyun might turn out like others did.
We must find him before that happens. So wake up, please.
You need to wake up. Aliens don't exist!
Here's one. She's an alien.
What about this?
Will you still say she's Han Jeong Yeon?
Do you get it now?
Why? Did she say she's not an alien and that she just looks like her?
Have you confronted her and asked her who she is?
Do you...
actually want to find Beom Gyun or not?
He told me...
that you'd believe him if you see that star-shaped thing.
So go and check.
I'm sure that alien, Han Jeong Yeon, took him.
That's you. And the boy beside you is me.
What is this?
It's you.
I know that you're Byul!
I...
don't know.
I don't know...
who I am.
I...
don't remember.
- What? - I...
don't remember anything...
about the times before I turned 18.
You don't remember...
Do you really not remember anything?
You really don't remember?
I got into a car accident when I was 18.
I was in a coma for a year.
When I woke up,
I couldn't remember anything about my childhood.
But this isn't me.
I mean, it makes no sense. How can this woman be me?
How can I look the same as I did 10 years ago?
Because you're Byul.
Who is Byul?
What is she?
An alien.
Why are you suddenly being like this?
What on earth did that girl say to you?
You said your brother was spewing nonsense.
Why are you calling me an alien now? Does that make sense to you?
Then what is this?
- What about it? - I gave it to you when I was a kid.
- Hey, Woo Jin. - Break it, then.
- What? - This is proof.
Have you lost your mind?
Why do I have to break it?
It's meaningful to me.
You have no memory?
Do you actually expect me to believe that?
I'm...
getting treated by a psychiatrist.
It's my sore spot.
Who do you think you are to touch it like this?
Break it, then. This is proof.
Hey.
This.
- What about it? - Where did I get it?
You made it when you were little.
When? How old was I?
You were in 3rd or 4th grade. You made it with your mom.
You didn't let me have it.
Did I really make it with Mom?
Yes.
Why? Are your memories coming back?
No, it's not that.
I was hoping it would bring back memories.
Jeong Yeon, take your time.
I said I'd make sure your memories come back.
Okay, Dad.
That crazy punk.
(Delete)
Here. She's an alien.
So what?
Why does that matter to me?
Suit yourself.
But if you leave now, I'll never see you again.
- Bluebird is the culprit. - Smile like that more often.
Why are you always so tense?
We can find him.
Just trust me.
You're pathetic.
My dad confirmed it.
It is mine.
He said I made it with my late mom.
It's the only thing she left.
I'm not lying.
If you don't trust me, that's fine.
What my dad says is...
all I can remember.
Can you just get away by saying you don't know?
I trusted you.
I didn't want to trust my brother who always babbled about aliens.
So I trusted you.
But...
I shouldn't have.
My brother was right.
You are Byul.
I'm...
Han Jeong Yeon,
Woo Jin.
Beom Gyun.
(Psychiatrist)
(Counseling, hypnotherapy)
What are you doing here?
Did you follow me?
You must now see that I really don't have memories.
- You might be acting. - That's enough.
What about Bluebird?
Why is your username "Bluebird"?
What's the problem? Why can't it be Bluebird?
That's...
the first word Byul ever said.
The blue bird.
"The Blue Bird" was my favorite book as a child.
I used to read it with my mom.
- It's none of your business. - Break the star open.
It'll teach you something.
My dad confirmed it.
It is mine.
Professor Han Yong Woo.
(Han Yong Woo)
What are you doing?
Which desk is mine?
It can't be that one.
Take this.
Okay.
Read it through within a week.
It won't be too hard for a top student.
I'll be done in two days.
Your desk is there.
It used to be Ji Hyuk's desk.
You wanted to take his place so badly.
By the way, what's going on between you and Jeong Yeon?
Why do you care?
- Is everything going okay? - Yes.
- Hello, Professor Han. - Hi.
Aren't you going to greet him?
Oh, hello.
Hi. I'm looking forward to working with you.
Thank you.
Here's the report you asked for.
It looks good.
Good job.
Thank you.
Professor Park.
I didn't know you could do things like this.
I heard you've been working with Professor Han for a long time.
What? Do you want to get on his right side?
I just have a few questions.
It's about Jeong Yeon.
What about her?
I heard she has no memories of her childhood.
Do you know why?
How do you know that?
- Well... - Why do you want to know?
Jeong Yeon told me.
Look.
Woo Jin, I don't know how close you are with Jeong Yeon,
but don't cross the line. It's Professor Han's privacy.
Hello.
Oh, that.
Like I said,
it's your own fault.
(Professor's office)
(Eunsung Psychiatric Hospital)
Where are you?
I'm at Eunsung Psychiatric Hospital.
Let me go! Let go of me, you jerks!
Let me go!
Min Young.
You're alone. You must believe me now.
Why did you tell Jeong Yeon to come here?
It's because Beom Gyun disappeared here.
What?
I saw a ball of light right there.
- A ball of light? - Yes.
When I got there after the light disappeared,
Beom Gyun was gone.
I just found his phone on the ground.
- Hey. - What?
Be careful.
Sorry.
Can't you put that away?
I can't. You never know when the alien will appear.
- It's dangerous. - You look more dangerous.
Go home if you're so scared.
We should find Beom Gyun.
- What was that sound? - I don't know.
It's an alien!
Woo Jin.
- Detective Hong. - What are you doing here?
Well...
Are you the culprit? That stun gun...
No. I can explain.
So this girl is not Bluebird,
- but she's just a witness? - Yes.
I saw it. He disappeared here.
Are you sure it was this place?
Yes, Beom Gyun was...
taken by UFO.
He was taken by UFO?
Yes, UFO.
Do you mean a flying disk?
Exactly.
An unidentified flying object?
Yes, UFO and aliens.
E.T.?
Do you mean aliens that can attack you with their mouths?
That's just movies.
- Woo Jin. - Yes.
I think she's a little ill.
I'm completely normal. I'm a medical student.
(Student ID, Park Min Young, School of Medicine)
So you really are a medical student?
That's a surprise. You don't look like one.
Fine, I trust you.
Put that stun gun away already.
I'm sorry.
Gosh.
How many times have we circled around this place?
- 3.6 times. - Is it really this place?
We haven't found anything.
Leave if you don't believe me.
You don't believe in UFO anyway.
Min Young. I'm sorry.
How many grown-ups do you think believe in UFO?
Hey.
Be careful. Are you all right?
You remind me of Beom Gyun. You look like him right now.
It's blood!
Hey.
Be careful. Are you all right?
You remind me of Beom Gyun. You look like him right now.
It's blood!
Detective Hong.
It hasn't completely coagulated yet.
If the blood on the floor has not coagulated yet,
it means it was shed 6 to 10 minutes before.
If the person is normal, that is.
How did the person go up there?
It's blocked.
The person either started from here and went out...
or came here from outside.
That's strange.
Could Beom Gyun...
- have been attacked here? - I doubt that.
There's no sign of struggle. Judging from the bloodstain,
the obvious thing is that someone passed here while bleeding.
Did the person go into the mirror?
Before, you talked about UFO.
Can't you be more consistent?
It doesn't make sense.
This is the crime scene.
Oh, no. Beom Gyun.
Something must have happened here.
This was recent.
Woo Jin, Woo Jin!
Detective Choi, listen carefully to what I'm about to tell you.
Woo Jin.
Woo Jin, that wasn't there before, was it?
Break it, then. This is proof.
("The Blue Bird")
Bluebird.
("The Blue Bird")
What about Bluebird? Why is your username "Bluebird"?
That's the first word Byul ever said.
(To...)
(To Byul)
It was me who gave her this.
Here. Your name is Byul from now on.
It's you. You are Byul.
My brother was right.
You are Byul.
(Byul loves Woo Jin.)
Byul.
Here. Your name is Byul from now on.
(Byul loves Woo Jin.)
- Beom Gyun. Beom Gyun! - Woo Jin.
- Beom Gyun! - Woo Jin!
- Beom Gyun! - Woo Jin, Woo Jin!
Woo Jin!
- Beom Gyun. - Woo Jin!
Beom Gyun, Beom Gyun!
Woo Jin!
Beom Gyun!
Beom Gyun! Darn it!
Beom Gyun!
(Part 2: The Great New World)
Please don't do this to me, Beom Gyun.
I had such a hard time.
I need you, Beom Gyun.
So please stop this...
and stay by my side.
Woo Jin. It's me, your brother.
It's me,
Beom Gyun.
Kim Beom Gyun.
Beom Gyun?
Gyeonggi Land at eight. Find a black hat.
(Sejong Motel)
Detective Kim's real name is Beom Gyun?
This doesn't add up.
What is he up to now?
I think he's going to meet someone.
- Who? - I don't know that far.
Listen to me carefully, Mr. Lee.
From now on, you can't miss even a move of Detective Kim.
I'll call you back.
Go and be on standby in General City.
No, I have to check with my own eyes.
He's Kim Beom Gyun?
Kim Beom Gyun.
Who is Kim Beom Gyun?
(Gyeonggi Land, General City)
Attention, General City citizens.
The city's fine dust concentration is within safe levels at the moment.
The warning for fine dust has been disabled.
Kim Joon Hyeok was Kim Beom Gyun?
What's going on? Whom is he meeting? Find out!
Yes, sir.
Go find out whom Detective Kim is meeting.
- Han Jeong Yeon. - Kim Beom Gyun.
Is it you?
Woo Jin. Where's Woo Jin?
Hang on.
Wait for me here for a few minutes.
- I have to get out of here. - What?
If you go with me now, you won't be able to enter Smart City again.
- I'm on the run now, you know. - What will you do?
I'll be in touch again.
- Jeong Yeon. - Hurry!
Darn it.
Hey, that way.
Han Jeong Yeon.
Bluebird?
- That woman is Bluebird. Get her! - This way!
- What happened? Turn on the lights! - Come on. Turn on your lights!
Hey, you guys go that way. And you guys should follow me.
Gosh. Hey, you guys should go that way.
Hey, hurry up! We have to find her!
Han Jeong Yeon.
Hey, she went that way! Go! We can't let her get away.
I'm Lee Ho Soo from Smart City Security.
Please come with me or you can go with Human B.
Hey, that way! Don't let her get away!
- This way. - Hurry!
Get her!
If I press this once, Human B will get here within three minutes.
What do you want from me?
My memories. Please lock them up again.
You're Bluebird.
The hacker who's been unlocking people's memories.
I do not want my memories to come back.
But you never wanted your memories to be erased.
Yes, that's right.
But now, I do.
Ask Human B to do it.
Do what you wish if that's your choice.
What about other people?
It wasn't a choice. Knowing nothing, they've fallen victim to it.
I'm trying to give everyone a chance to make a choice.
Who do you think you are? No one gave you such right.
It's because...
I'm the reason all of this happened.
What do you mean by that?
I...
I have to do it.
You won't be able to.
What is your relationship...
to Detective Kim?
Kim Beom Gyun.
Han Jeong Yeon.
What is going on?
- Sir. - Did you find her?
I apologize. We haven't yet.
I'm certain that she's Bluebird. I saw the symbol,
and she even crashed General City's system.
You said her name is Han Jeong Yeon, right?
How do you know her, sir?
- I went to university with her. - Pardon?
She seemed to be in her 20s.
Jeong Yeon.
What's going on?
Are you saying Han Jeong Yeon is Bluebird?
I was told to come to where I went with Woo Jin in the past,
so I thought it was him.
So? Did you meet her?
She must know where Woo Jin is.
I went to meet her,
- but jerks from Human B showed up. - You should've called me.
I wasn't in my right mind. I told you I thought it was Woo Jin.
Goodness.
By the way, where's Min Young?
Doctor,
I want the microchip removed.
The headaches are so bad, and the memories are haunting me too.
I want to get rid of all the mess in my brain...
and turn myself in.
Doctor.
You might lose your entire memory if the surgery doesn't go well.
Even if that doesn't happen, you'll have to live with the scar forever.
Like this.
And the memories are haunting me too.
I want to get rid of all the mess in my brain...
and turn myself in.
Doctor.
You might lose your entire memory if the surgery doesn't go well.
Even if that doesn't happen, you'll have to live with the scar forever.
Like this.
You had a microchip removed too?
20 years ago.
To be accurate, it wasn't a microchip.
Back then, it was a bug.
A blue bug.
- Come. Come here. - For goodness' sake.
Gosh, let go. What's your problem? What's this about?
I think there's something only I don't know.
You must know what's going on between Joon Hyeok and Doctor Park.
Gosh, was that what this is about?
They're very close as they've been friends for over 20 years.
Are they more than friends?
No, I don't think that's the case.
I think they have a connection that surpasses romantic love.
They're closer than family. I guess it's between love and friendship?
Why? She's pretty, easygoing, and intelligent.
Why would she feel a connection with Joon Hyeok? Nonsense.
What are you talking about? What does Joon Hyeok lack?
He's handsome and strong.
He wasn't studious, but he's actually very smart.
As for his personality... He sure is a man's man.
He doesn't lack anything!
Have you gone crazy or what?
Hey, you called him a jerk first even though I spread it.
What?
Joon Hyeok, I taught him a serious lesson.
We'll follow you in right away.
- You guys are two peas in a pod. - He taught me a serious lesson.
Goodness. Great work.
I'll wrap it up and see you inside.
- Min Young. - What happened?
- I saw. - Who?
Woo Jin?
- No, Han Jeong Yeon. - What?
She's Bluebird.
What about Woo Jin? Was he not there? Where is he now?
I couldn't talk to her.
Jerks from Human B showed up all of a sudden.
She said she'd be in touch again.
We have to track her down. She must know where Woo Jin is.
They left you in my hands and left together.
That was the last time I saw him.
He might be with her now.
Jeong Yeon will be in touch again soon, right?
But what if those scums from Human B try to interfere again?
You said they saw you with her.
Will you be able to enter Smart City again?
Won't it be dangerous?
There's someone who can help me.
You think Human B has been locking people's memories?
Can you prove it?
I'll be able to if I can meet Bluebird.
Detective Kim, you've already caused enough trouble.
Human B won't let it slide.
That's why I came to see you, sir.
Why do I have to help you?
Because you're the mayor of Smart City...
even though people don't really know that.
- I beg your pardon? - Well, what I'm saying is...
people here seem to think...
that the chairman of Human B is the mayor.
It's time to do some real politics.
Don't get bossed around by Human B. Do what you want to do.
I'll let you do as you wish, but you must not make any mistakes.
Sir, it's me.
We should meet.
Sir, it's been a long time.
Please talk casually to me. I'm much younger than you.
My throat is all sore because of the polluted air.
I visited an elementary school in General City yesterday.
Do you know what color kids used when they were asked...
to fill in color for the sky?
They used brown.
From the sky to the ocean, everything is murky brown nowadays.
Yet we still call the color "sky blue". How ironic, don't you think?
You're okay with sea bass, right? It's in season now.
The same goes for the sashimi here.
This restaurant only uses wild caught fish.
But now, they can only get their hands on a few a year.
Fishermen have to go at least 300km to catch one fish.
Even the rich don't get to eat this stuff.
I made a special request because I'd be meeting you today...
Let's eat a bit later.
Gosh, I'm hungry.
I'd like to talk with you about...
Do you know why I had to reschedule this meeting today?
So many countries are dying to import the Human B System.
How much do you think we're talking here?
It's one of the government's long-cherished ambitions.
If the results aren't successful, I'll lose my job.
If problems arise after the system gets exported,
you won't be able to cover the losses with money alone.
Then you sure will lose your job.
So you're saying the problem is...
Human B has been locking people's memories.
I think we should start an investigation to find evidence.
- Gosh, that's preposterous and... - I need a search warrant.
Please help me.
The chairman of Human B won't be an easy target.
I've never met him either,
but you'll get in trouble if it goes wrong.
It's my job.
I'm the mayor of Smart City.
All right.
Please find firm evidence so that the warrant doesn't get denied.
My life is in your hands now.
Thank you, sir.
Now, we're good. Then let's please eat.
By the way, how did you find out about the issue with Human B?
A detective from General City is in Smart City now.
A detective is in Smart City?
Actually...
There was an incident.
What kind of incident?
Yes, sir.
Han Jeong Yeon is Bluebird.
And Detective Kim Joon Hyeok...
is Kim Beom Gyun.
By any chance, did you already know about it?
Got it, sir.
What should we do?
Han Jeong Yeon will make our system crash completely.
She'll probably think she has to do it...
like she did in the past.
Kim Joon Hyeok, I mean Beom Gyun. She must've dragged him into this.
Yes, sir. Got it.
Shall we deal with Detective Kim immediately?
No, just leave him.
Pardon?
The chairman instructed me to do so.
He'd make great bait for catching Bluebird.
- What did you say? - I said we can't do it for you yet.
I gave you all the information on Kim Joon Hyeok.
Wasn't that the condition?
We now need more help from you.
We found out that Detective Kim and Bluebird go back a long time.
They only have one goal, Human B.
- He'll lead us to Bluebird. - Then what?
What will come after that?
Will you ask me to kill someone or what?
Your memories will become more vivid as days go by.
When all the memories you want to erase are back,
you won't be able to handle it.
- Are you threatening me now? - Not at all.
It's just a word of advice.
- Detective Kim. - Yes.
Oh, thank you.
What happened? You vanished, and I couldn't get a hold of you.
Thanks to you, I was harshly scolded by the mayor.
I'm sorry. Something came up.
I'm not sure what it was about, but please don't do that again.
All right.
By the way, are you okay?
I started feeling better as soon as I came back to Smart City.
Gosh, you were certainly born to live here.
- We should eat something. - Shall we?
What should we eat? Shall we go for pasta?
Sure.
Just a second, please.
Please come to the director's office. It's urgent.
Let's eat together another time. Something urgent has come up.
All right, then.
Why isn't she contacting me?
- Are you here to report something? - Pardon?
You wanted me to come here.
I did?
Follow him.
Woo Jin is here.
Right here, in Smart City.
(Circle)
This is the ambulance, isn't it?
We have to find that ambulance. If not, Beom Gyun might die too.
It's not registered? Nothing is in the surveillance camera?
Nothing was filmed.
Are you certain you checked every footage?
Professor Han, what are you doing?
Why don't I have my memories?
Did this person experiment on you?
Will we really find something?
Was there an experiment? Who conducted the experiment?
Does the chairman have Woo Jin?
You've been watching everything. Haven't you, Bluebird?
Who is the chairman? Who is he?
Please. Just lock my memory!
This might be related to Woo Jin's disappearance.
Where is the person who gave you the note?
Where is that person?
You are going to raise the stakes?
I don't want to lose my memory again.
Woo Jin.
