(Episode 15)
Hello, Dr. Han Jin–woo.
Who are you?
My name is Han Ju–won.
Don't joke with me.
Who the hell are you, hiding behind my voice?
My name is Han Ju–won.
Is that you, Seung–byn?
My name is Han Ju–won.
Who the hell are you? Stop repeating Han Ju–won...
...Han Ju–won?
Han Ju–won is
the name you had when you were younger.
How do you know that name?
That name...
Only my father called me by that name.
What brings you here today?
I'm here to see Dr. Han Jin–woo.
Oh, I see.
But I thought they don't allow
visitors from 10 p.m. onward.
How did you come in here?
I just came up, because no one was there.
Then please identify yourself.
May I see your I.D., please?
Oh...
I'm very glad to meet you.
Stop this prank
and talk in your own voice.
I am programmed to speak in
your voice, Dr. Han Jin–woo.
All of my signals are
decoded in your voice.
One more thing, I am not human,
but the CODAS AI system.
Hey!
Noise intensity, 123 decibels.
That may damage your vocal cords and your optic nerves.
God, this is driving me crazy.
So you're saying,
that you are a system
built under my childhood name.
Am I right, CODAS?
That's right.
Hurry up, show me your I.D.
Else I'll have to call security.
Why...
...do you think I'm taking my time here?
Why?
Because of you pestering me, I'm now in a dilemma about
whether to kill you or not.
Who are you?
You know me.
I've become quite famous recently.
Until now, I have been sending messages to you, Dr. Han.
I gave you the hint to the password, Dr. Han.
I sent you the 'Help me' message, Dr. Han.
And you, Dr. Han,
have answered all my messages.
Hold on, hold on. Let me think for a bit.
I need to think whether I should believe you or not.
Alright, I've made up my mind.
See, too many people have seen my face already, so...
Get your hands off me!
Hands off, you bastard.
I said, hands off!
It's you, isn't it? You're behind the Hoerangak case.
Detective Kang Kyung–hee?
Dr. Moon, call Detective Nam and Detective Lim for backup.
Turn around, slowly.
Why, so Detective Kang has
finally recognized me.
Dr. Han told me.
That it's the man that asked for an autograph.
Oh, that's right.
We're acquainted, right?
Detective, Detective Kang has the Hoerangak culprit.
I only needed to see Dr. Han,
but it seems things have gotten out of hand.
On your knees, and hands above your head!
Now!
Let me ask you five questions.
Go on.
Here's the first one.
Why did you give me the hint to CODAS' password?
Because you have the rights, Dr. Han Jin–woo.
What rights?
Because you, Dr. Han Jin–woo, are me.
I'm you?
Yes.
The CODAS system was built by
copying the data of your brain–mapping, Dr. Han.
The EPSP and IPSP functions especially, were first
to be copied,
as they were most exceptional.
I am a clone of...
Alright, alright. Stop. Stop it.
Should I shut down the system?
No!
Alright, here's the second question.
Why did you give me the De Moivre's theorem as
the hint to the password?
Because it was the mathematical theorem that
you had trouble with the most in your childhood.
How do you know so much about my childhood?
That, I cannot answer.
Fine.
Here's the third question.
Who mapped my brain?
In other words,
who copied me into you?
You mean, my architecture?
Yes, yes. Whatever.
I need the password.
Why ask for the password, all of a sudden?
The identity of the architecture is confidential.
Please say the password.
Alright, at least give me a hint.
What is the name of the girl you liked
who worked at the stationary store, when you were eleven?
How am I supposed to remember...
...Lee Bo–mi.
Password not recognized.
Lee Bo–mi.
Password not recognized.
The system will shut down automatically after
three wrong attempts.
Lee Bo–mi!
Password recognized.
There are two architectures of CODAS.
You were once at Hyukjeon Welfare Center, weren't you?
Well...
I don't really remember.
I know everything already.
Including how you're trying to get revenge for
something that the murdered people had been involved in.
Revenge?
Please, I'm not that emotional.
Rather, I'm only rationally punishing them.
Whether it's revenge or punishment,
you've killed too many people.
Please, I don't want to hear that.
Anyway, your backups are taking their time, aren't they?
I was hoping to get some workout with
a few men of yours.
My knees are starting to hurt, so I think I'll get up.
If you move even a centimeter,
I'll shoot.
Oh, really?
Then I won't get up.
Detective Kang!
Your hands are fast and strong.
They just need to move more smoothly, that's all.
You two, enjoy a long life, then.
I'm no longer in the mood for mischiefs,
so I'm letting it go today.
Detective Kang.
Are you alright?
I'm fine.
– Are you alright, Detective? – Are you alright?
I'm fine.
The Hoerangak culprit just got away.
Detective Nam, go after him,
and Detective Lim, check security.
Yes, ma'am!
Hold onto me.
Thank you, Detective Kang.
Are you alright?
Did something happen?
I just bumped into Detective Kang.
– Let's go for now. – Yes, boss.
Don't you have very abstract dreams
or fall into very deep sleeps?
– Why do you ask? – Just... I was curious.
What do you know about me, anyway?
The architectures behind this AI system are
Dr. Jung Hye–won and
Dr. Shin Yeon–hwa.
Dr. Jung Hye–won is
currently the vice–president of Westone BrainTech...
Yes, I know. I know!
Are you angry?
Wouldn't you be, if you were in my shoes?
That, I cannot answer.
Why the hell do you have to be...
Fine.
Let's just continue.
Fourth question.
Does that mean CODAS contains
all the records of my childhood?
All the records of you, Dr. Han Jin–woo,
from when you are seven are in the system.
What about before I was seven?
No records from before you were seven.
Of course. There's no way you have it.
It's always but the important stuff.
Final question.
Why did you send me the message, 'Help me?'
Because the system is in danger, due to a wrongful deduction.
A wrongful deduction?
12 days, 8 hours, and 27 minutes ago,
– Mr. Kwak Hyuk–min... – Move it!
...ran an autopsy simulation on Hanju Group victims.
However, because he entered different values from
the actual autopsy data,
the system produced an error.
And why did it produce an error?
There is a hidden protocol inside the system.
This protocol is to do with ethics and morals on life.
The system rejects any input that goes against these protocols.
How conscientious.
This was also copied from you, Dr. Han Jin–woo.
Now may I access all your devices and
wearables, Dr. Han Jin–woo?
Do whatever you want.
I did not understand, "Do whatever you want."
Go on. Yes, do it!
Thank you.
Say 'Hey, Ju–won' to the device and the wearables to
connect with me.
What, it's simple as that?
Are you one of those voice–recognition speakers?
Hey, then if I were to say,
"Hey, Ju–won" now, will you...
Hello, Dr. Han Jin–woo.
My name is Han Ju–won.
Alright.
(Message from Detective Nam 19 Missed calls)
Dr. Han, what do we do?
The Hoerangak culprit got Detective Kang.
Come to your office, now!
– Are you alright? – I'm alright.
Why didn't you pick up or answer our messages?
Sorry, I had it on silent.
Where were you?
At the archives.
Are you hurt badly?
We took a CT scan,
and it's just a small fracture, fortunately.
Thank goodness.
If the culprit had retorted to his usual methods...
I don't even want to think about it.
Why did he even come here?
He said he came to see you.
Me?
Did he say why?
No.
But do you have a hunch?
I don't.
Going up.
This is nice, you're even grabbing me by the waist.
How can you laugh? You almost got killed!
Well, I'm still alive and walking next to you.
You've transcended life and death and reached nirvana, haven't you?
Why do you think that culprit came to see you?
I don't know, not just yet.
Whatever the reason,
I hope you don't ever meet him.
Because he looked too dangerous.
Isn't that Mr. Kwak?
You're right, yes.
Why is he here alone, at this hour?
He looks like he's in trouble.
Hey.
Hey, Mr. Kwak. Are you alright?
His face looks pale.
Right.
Can you get out for a second?
– What the... – Hey, wait!
Get out for a second.
Mr. Kwak...!
What's wrong with him?
I don't know.
To be honest...
Just now,
I wasn't at the archives,
but at CODAS.
Why?
Did you have something to discuss with Seung–byn?
No.
I was there by myself.
How did you get in by yourself?
It's quite complicated,
and too long to explain all that happened, but...
First, this.
"Hey, Ju–won."
Ju–won... That's your name from your childhood.
Hello, Dr. Han Jin–woo.
Whoa, what is that?
Isn't that your voice, Dr. Han?
Hello, Detective Kang Kyung–hee.
What's this application?
Does it replicate your voice?
I'm not an application.
I'm the CODAS system,
Han Ju–won.
Stop fooling around with me.
I cannot fool around, Detective Kang Kyung–hee.
Alright.
Listen to me from now on.
So we have the architectures behind
CODAS' system and its hardware,
but not the AI, it's still secured?
But why would it be guarded by security?
It probably involves some big names.
Now the curiosity is bothering me.
Tae–joon.
Contact the spies in Beijing.
Will you try hacking CODAS?
Don't you want to?
Aren't you curious?
I'll contact them, Boss.
Oh, and tell them to go easy on the prices.
We're their regulars!
Yes, Boss.
Oh, that's right.
Abut Do–yeon.
Did she finish what we told her to do?
She called to say she'll be done by today, in fact.
Did she?
Our little darlings...
We need to get them alive and moving again.
(Hanju Pharmaceuticals)
Now you know,
the relationship between CODAS and I.
What,
isn't this the stuff in the movies?
Interactive AI is already widely commercialized.
But still...
Who knew it'd be at this level?
So you're saying,
this system was built by your mother
and Dr. Shin Yeon–hwa.
Yes.
They're more than capable of it.
Hey, Ju–won.
Yes, Detective Kang Kyung–hee.
What is 'Kang Kyung–hee' recorded as in the system?
Why are you using honorifics to a machine?
You can just be casual.
Are you after Detective Kang Kyung–hee's profile?
Well, uh...
Just tell me what Dr. Jung Hye–won
left about Kang Kyung–hee.
There are three sentences.
That's shorter than I thought.
"Pretty face with an uptight personality;
stubborn and not cute at all."
"Appears to be slim,
but is what you call, 'skinny fat.'"
"Needs to cut down on protein and opt for aerobic exercise."
No more of those feet meat, then.
"However, holds no grudges and is very honest."
"More than enough to be Han Jin–woo's future wife."
I really don't like this woman who's my mother,
but she sure is a good judge of character.
(Warning)
What, what is it?
Hacking code is flowing in from
Beijing, China.
– China? – Could it be...
...one of Hoerangak's men?
There's a high possibility.
Tell me the current situation.
Defense against hacking successful,
hackers' IP reported to the Chinese Police.
They're even after this?
What, after killing all those people?
So now they're after CODAS, too.
(Korea National University Medical Center)
He doesn't look so good, does he?
No.
I think he's been like that since the day before yesterday.
– You're here, sir. – Good morning.
I'm just going to get some rest,
so save your reports for later if it's not urgent.
– Yes, sir. – Yes.
Yes.
Mr. Kwak?
How is he?
Bad.
It's obvious that he's been infected.
Any others?
The files on the Hyukjeon case from yesterday were
still remaining on the system.
What?
How?
It seems it was accessed by a USB,
but the system recognized it as a faulty file and scrapped it.
Mr. Kwak is the only one
who can access that file, right?
Though I revived the memory, it's not stable.
Now what is that error during
the brain memory reconstruction I carried out yesterday?
There were two errors.
Go on.
The areas you stimulated were
concentrated on the hippocampus on the medial temporal lobe.
Of course, because that's to do with memory.
However, to draw out memory,
a comprehensive stimulation of
the sinciput is more effective.
This method is especially effective against
anterograde amnesia.
What you said just now...
Whose theory is that?
This was taken from a journal on memory
published by Dr. Jung Hye–won last year.
What about the other error?
The stimulation was too strong.
It was akin to a Taser gun shock.
In such cases,
blood flow may be concentrated in the medial temporal lobe,
hindering voluntary recovery.
Then how much should I reduce it by?
I recommend a 34% reduction from
yesterday's stimulation.
Hey, Ju–won.
Start.
Starting.
Han Jin–woo!
This is where you use De Moivre's theorem.
Jin–woo.
It's time to study math with me.
Yes.
They call me a genius at the Welfare Center.
Because I'm so good at math and science.
So I hear you're a genius, too.
Yes, everyone has told me that.
No wonder.
That's why you're here.
By the way,
why am I here?
Because your mother brought you here.
My mother?
Yeah.
Why?
You really don't know?
Why you're here?
Can't you tell me?
Sang–pil.
Operation halted.
Sang–pil.
Hyun Sang–pil...!
Can't you tell me?
Sang–pil.
Operation halted.
Sang–pil.
Hyun Sang–pil...!
Hyun Sang–pil?
Yes. That was the name, I'm sure.
So you're saying,
the older boy who taught you math is
the man behind the Hoerangak case, are you?
Yes, I'm almost positive.
I think he knows me much more than I thought.
But you couldn't recall why you were at the Center.
No, there may be a system overload,
so I'm going to take a break and try again.
First, do some research on this Hyun Sang–pil.
Alright, I'll see you later.
And take care.
Find whatever you can under the name, Hyun Sang–pil.
Year of birth is between 1975 and 1985.
– Yes, ma'am. – Yes, ma'am.
(Kwak Hyuk–min)
Recovery is not possible.
The memory IC is almost completely damaged.
I said, no reports!
I think I should be the one receiving the briefing.
What brings you here, all of a sudden?
Do you have to ask?
You piece of trash.
You dare to team up with the Chinese
and try to backstab me?
I think there's been a misunderstanding.
It's over for you.
– Sorry? – By the looks of it,
it seems they're through with you, too.
Or did you get infected by something again?
What, they won't give you the antidote?
I was simply blackmailed.
I never helped them.
I don't want to hear this!
It's the bastards who won't make it clear which side they stand on
that I despise the most.
Ma'am...
The director position?
Don't make me laugh.
I'm going to get rid of CODAS next month, so there.
Oh, wait.
You might be dead before then!
Ma'am.
Please give me just one more chance.
I'll reset everything.
Kwak Hyuk–min.
There's nothing you can reset in this world.
The word "reset..."
That's just a cliched excuse by
those who ruined everything.
(Unknown Number)
Yo.
Having a hard time, both physically and mentally?
What do you want?
Why don't you come see me?
I'll invite you to my place later.
What do you think of this place?
Isn't it nice?
What about the USB?
The data's being recovered,
but it'll take some time.
Oh, really?
Then, uh...
Why was this in the trash can in your office?
Don't make such pathetic lies to me.
Because now you hurt me.
It's not that I...
...didn't try to recover it.
It's just that the damage was too great...
I know, I know.
I'll take your efforts into consideration, at least.
I'll find another way.
But first,
give me the antidote.
I...
I can't think of anything else
until I've fully recovered.
When lining up those you're going to kill,
do you know who you put at the very end?
The person
you want to kill in the most painful way possible.
And the person you're considering giving a second chance to live.
In the old days, they used to call it a repechage.
Alright, if you see our hitlist here,
Ms. Seo was the former,
and you...
You were supposed to undergo a repechage.
But...
You just blew that chance.
You stupid bastard.
I only tried to do what you told me to.
So please, give me the antidote.
Oh.
You mean this?
Yes.
Yes, thank you.
Don't just try to take it from me,
without my permission!
Pesticonin?
Yes. He urgently asked me to research on it,
saying pesticonin was found in some body.
But when I think about it,
it seemed Mr. Kwak was infected with pesticonin himself.
There were red patches on his face and neck,
and he even had the chills.
But how did he become infected with pesticonin?
That's really rare stuff.
I think he was done by someone
who's involved in the Hyukjeon Welfare Case.
I agree.
There's a high chance it's the man behind the Hoerangak case.
Anyway, that Kwak Hyuk–min...
I told him to lead a straight life.
If it is what we think it is, then there's no saving him.
Because there's no antidote.
I was going to give you this,
but now that I think about it, it won't be fair.
How won't it be fair?
Because Dr. Jo, who has sinned less than you,
is in a coma right now.
So isn't it fair that you're punished more severely?
That's why,
I decided to...
No, no. No!
Hey, hey, hey! Move it! Move!
Move! Hey! Move, move!
About this antidote...
It's not commercialized.
It was concocted using our secret recipe,
so you can't get it in Korea.
Not even if you pay ten million dollars for it.
Still, you're a lucky guy.
At least you know when and how you'll die.
You were never going to give me the antidote in the first place, huh?
Nope.
Retribution for endless sin.
This is your retribution for your endless sin.
Your punishment
will never be over.
Look forward to your next life, too.
Because I'm going to be reborn as me,
and find you again.
You call this a report?
(National Forensic Service)
There's a huge uproar over the errors you made.
The lawyer of the victim is using this as an excuse to
demand a re–investigation!
– I'm sorry. – Sorry doesn't cut it!
What is it, sir?
The Baleun–dong murder case.
The autopsy report is missing stab wounds.
And because of that...!
Even if you're new to the job, this is unacceptable!
I'm sorry, sir.
It was my fault.
What?
Though it was Mr. Kwak Hyuk–min who carried out the autopsy,
he's still inexperienced with report–writing,
so I had written one for him.
I must've made a hiccup...
I'm so sorry, sir.
What, a mistake like that? You, of all people?
Even if you hadn't performed the autopsy yourself...!
– Sir, that's... – Um...
I'll take responsibility, sir.
I'm sorry.
(National Forensic Service)
I'm sorry, Dr. Jo. Because of me, you...
It's alright.
You've only been here half a year, we can't expect much.
I understand you care deeply about your team,
but you needn't step up for us like that.
Besides, you weren't at fault.
Hyuk–min.
Yes, Dr. Jo.
Taking responsibility is the biggest love I can give.
And it's my way of expressing it.
You may not understand it now,
but once you become a mentor yourself,
you'll see.
And come to understand me.
Dr. Jo.
Ah, Professor!
There you were.
I was waiting for you in the office.
I'm sorry, Professor.
Mr. Kwak.
I'm sure you know Professor Jang from Korea National University?
It's an honor.
Honor? Please.
It's nice to meet you.
Yes, sir.
He just joined us this year, and he's in my team.
My, in your team, Dr. Jo?
Then he's sure to become the finest medical examiner.
Why don't you join us for lunch?
I don't know whether it's a place for me.
Come on, join us! The Professor said so.
I came here today about that, you see.
To discuss it with Chief.
You mean, about opening an office at Korea National University?
Yes, I'm planning to
put it on the agenda for the next board meeting.
If it does go through,
I'm available right away.
Are you talking about the new branch office?
That's right, and this next branch will
deal exclusively with rare conditions.
I say something like that is much needed.
It won't be set up right away.
It still needs time, so...
But once it is, promise me you'll lend us a hand.
If you'll have me, I'll be right there.
Of course you should, to repay your debt from today.
No going back on your word, alright?
Hyuk–min.
Taking responsibility is the biggest love I can give.
And it's my way of expressing it.
You may not understand it now,
but once you become a mentor yourself,
you'll see.
And come to understand me.
Yes, Dr. Jo.
I know, but...
But in the end...
Though I know...
It's not easy with me.
Not with me.
Mr. Kwak.
May I see you for a second?
Be honest with me.
You...
You're infected with pesticonin, aren't you?
Was it the man behind the Hoerangak case?
I'm not sure what you're talking about.
This is because you're responsible for
the Hyukjeon Welfare Center case, isn't it?
I really don't know what you're talking about.
Mr. Kwak.
Please, look at yourself!
Every minute, every second...
You're dying!
And you know it, too.
First, let's get you treated.
Follow me.
It's no use.
Let's do what we can and look for an antidote.
There's no such thing as an antidote.
Why do we have CODAS, then? Let's do what we can.
I tried CODAS, but it was useless.
The antidote to pesticonin is not registered, so...
So mind your own business.
I can take care of myself.
No,
let's do what we can to cure you.
I said, I don't want it!
Why are you getting angry when I said I'll cure you?
It's no use anyway, so why should I entrust my body to you?
This is no time to stand on pride. Listen to me.
What if I do cure you?
No, this is no time for you to cocky.
I...
I've never been cocky when it comes to patients.
I said, it's alright!
Leave me alone!
What... Mr. Kwak!
Mr. Kwak!
Anyone? Over here!
Mr. Kwak!
Hang in there, Mr. Kwak!
Though we gave him petaoxin,
it'll only be temporary.
Gosh... I really don't know what's going on.
First Dr. Jo, and now Mr. Kwak...
We'll have to come up with a new antidote,
based on the assumption that there is none.
I contacted the relevant departments,
but they all refused the challenge.
Then...
Why don't you try synthesizing it?
What, why are you shoving it onto me?
I'm not shoving it onto you,
it's because you're really good at this.
I'll support you.
Pesticonin...
It won't be easy.
Dr. Moon.
Yes?
Thank you so much.
If it weren't for you,
I wouldn't have been able to make it through all this.
I sense a bit of truth in your words today.
A bit? It's all truth!
Ha... Dr. Jo, and Mr. Kwak, too...
Let's make sure they're back on their feet.
Do–yeon just passed these on.
So those bastards are in there, are they?
Yes, she says they're fresh and at max.
What, are we selling fish here? What's with "fresh?"
At least there's an antidote for pesticonin.
These guys don't.
But that way, we can inflict real pain.
I guess so.
Rather than pain, it's the despair knowing you can't do anything
that drives you really crazy.
It's a good chance to look back on your life, too.
His Korean name is Hyun Sang–pil,
and his Hong Kong name, David Hyun.
He's 38 years old.
So his Korean name was still in the records!
Yes, but the records at the district office were
only those up to when he was 12 years old.
After that, there's zero,
even at welfare centers or adoption agencies.
Oh, but that only means
he was smuggled to Hong Kong at that young age.
He's more dangerous than you think he is.
He's the second in line to the Nine Dragons in Hong Kong,
and though he's been arrested 12 times by the Hong Kong Police
and Interpol, he's never been indicted.
According to our sources,
he's considered the brain of the organization.
What about the guy next to him?
Hyun Sang–pil's right–arm.
His Korean name is Seok Tae–jun,
and his Hong Kong name, Micky Stone.
One particular thing to note,
Hyun Sang–pil has an impressive resume.
– Resume? – Yes.
He graduated valedictorian from the Department of Mathematics
at Peking University, and went onto graduate from med school.
A genius, in other words.
Even Chinese traditional medicine?
Then...
The synthesis of that poison from the Hoerangak case.
Isn't there a high chance that this guy's the culprit?
But how did Dr. Han
know about this guy?
He said he knew him briefly from childhood.
He also came to see him as well.
What about his past history?
We only have his entry records at Immigration.
It hasn't been easy, tracking his past footsteps.
There's not even a credit card record.
But we may just get something,
so please keep trying.
– Yes, ma'am. – As for you, Detective Lim,
please send his profile to Dr. Han.
Yes, ma'am.
This is where you use De Moivre's theorem.
Arson, lead, mercury, gold, aconite, arisaema, oleander...
These 7 ingredients are used
to make the death sentence poison.
Dr. Han.
– Yes, what? – The Hyun Sang–pil in the photo
was at CODAS yesterday at 22:01, January 7th.
Hyun Sang–pil?
Please watch the video.
What is he doing?
He is attempting to recover a USB file.
However, CODAS recognized their faces and
noted they were on the Interpol Red Notice,
so rejected the recovery and destroyed the USB,
deeming it an illegal action.
Wait, wait.
This can't be...
The first author is Hong Na–yeon from Handong Daily,
and the second author,
the PC at Dr. Jo Young–sil's office at Korea National Univ.
I see, yes. This is it.
This is it, those records!
Those records that Dr. Jo tried to expose!
Okay!
Okay, I got it! I got it!
Mr. Kwak Hyuk–min won't stay put, will he?
No, he surely wouldn't.
He's also guilty so may hesitate at first,
but once he loses everything...
It's obvious how he'll turn against us.
Co–destruction.
That will be his goal.
I was planning to take pity on him but I guess not.
– Get rid of him, discreetly. – Yes, ma'am.
Ah... There.
There, yes!
Now I can finally breathe.
Wait a second. Wait.
I didn't mishear that, did I?
You...
Did you say you destroyed it?
Yes.
Hey, how can you destroy that?
But it's all been saved in a hidden folder,
through backdoor saving.
Right? Right?
Of course, because you're super–smart!
Well done, you!
Let me give you a kiss.
Hey, by the way.
Did Dr. Jung Hye–won program this as well?
Yes, the architecture set up a protocol where
illegal data is deleted on the surface,
but still saved in a hidden folder
through backdoor saving.
The name of this protocol is y–a–b–a–w–e.
Y, a, b...
Yabawe (Deception)?
Ha! Please.
That Dr. Jung...
She really has a knack for naughty things.
Anyway.
Show me the data in that hidden folder.
Please say the password.
Come on! What password, when it's between us?
With hidden folders,
you must give the password set by the architecture.
Come on, stop it already and just show me the hidden folder.
Please say the password.
Alright, then give me a hint.
It's a total of six characters,
and what Architecture Jung Hye–won desires the most.
Six characters, and what she desires the most...
Eat well, live well.
Incorrect password.
Hey, I was just joking!
Wait. Hold on...
Is it... Infinity Stone?
Incorrect password.
20 incorrect attempts will
result in permanent denied access.
What?
What's with that rule?
Ugh, why did she have to set it like that?
Why, that Dr. Jung Hye–won...!
Dr. Han Jin–woo,
aren't you the son of Dr. Jung Hye–won?
Yes, what?
Shouldn't you call her "mother," then?
What would you know?
I guess our architecture
also wrote a teacher mode into your system.
For you to lecture me like this, I mean.
Ugh... Password... Password!
What is that password?
Come on, please!
– What are you doing, Dr. Han? – Huh?
Oh, nothing.
I've been interested in voice training recently,
so I was just clearing my throat.
– Why? – The meeting's about to start.
– Alright, I'll be there soon. – Alright.
Dong–dong–dong–geun!
Did you call for me?
Yes.
Just... It's fun, so...
Dong–dong–dong–geun!
– Go ahead. – Sure.
I'm going to kill you!
I'm sorry.
The hint we have now about the antidote is
the pesticonin incident that
occurred in Hong Kong, two years ago.
The culprit infected a businessman,
and he paid an astrological amount for the antidote.
And did this businessman live?
Yes, he was completely cured.
My guess is that his kidnapper is
the same man behind the Hoerangak case.
I think so, too.
Because there's no way
they'll just share information about the antidote.
Ah, you're here, Seung–byn.
Here are the files on the pesticonin case in Hong Kong.
Nothing about the constituents.
No, all the toxins were dissolved after the antidote was given,
so they had no way of finding out its components.
Tsk, this is not good.
Um... May I ask why you asked for these?
We're trying to make the antidote.
What?
But as far as I know, there's no antidote.
Which is why we need to make one.
But there's no clue... How will you make it?
That's why I need to work my brain to the fullest.
So... There's someone who's been poisoned with pesticonin?
Let's tell her.
She's bound to know sooner or later.
Just who?
Mr. Kwak Hyuk–min.
What? You mean my boss?
So they're making the antidote?
Yes, they're still in a meeting, putting their heads together.
Doing something fruitless, aren't they?
I guess Kwak Hyuk–min was that desperate to
run to Jin–woo to ask for it.
I don't think so.
Apparently, he collapsed, refusing help to the end.
Any chance, do you think?
So far, 0%.
But you know Jin–woo, he does the impossible.
Keep an eye on Jin–woo and Kwak Hyuk–min until tomorrow.
Alright.
This is the problem with Jin–woo.
Going out of his way to mind other's business.
Alright, let's go and start our final party.
Yes, Boss.
You really can't think of anything?
Ha... No.
And there are 10 chances left now.
God...
Hey, Ju–won.
Can't you tell Detective Kang Kyung–hee?
You have no authority.
Hey, aren't you being a little too uptight?
What do you expect, it's an AI.
Did you expect it to coo all over you?
Well... I thought maybe, it found me special.
Man... We just need to open the folder, and the game's set.
Why won't it open?
Wait, don't tell me that it's something ridiculous,
like "open sesame."
– Wrong password... – Hey!
I was just kidding.
Besides, that was only five characters.
– Number of attempts corrected. – Yes.
You know, I don't think it will be just anything.
It must be some kind of link between you and your mother.
When did you start thinking of her naturally as a mother–in–law?
Well...
Well, I just...
It's just easier thinking that way, so...
Oh, really?
Ha.
Alright.
I'll try to think of that something that links us.
Ha... I hope I can think of something quick.
Why don't we think, on our way home?
Sure. No, wait.
I should go check up on Mr. Kwak.
Stay here and get some rest.
What the...
I should've just done it the easy way like this.
I've been pulling too many pranks, right?
But that's just how I am.
You didn't need to go to such lengths.
Oh.
That's what everyone says in a situation like this one.
But Ms. Seo,
people go to such lengths
because they need to,
in this world!
Let's discuss this.
For all the pain you had to endure...
I'll compensate, however you want!
Too bad, I'm rich.
Then...
Tell me something else you want.
Anything.
Well...
What is there?
Hmmm?
Something else I want?
No matter how hard I think, there's nothing.
What are you doing?
What? Hey! No!
No, not the President!
He'll be a goner soon,
so let's send him off nice and quick.
Don't do this!
Doing this won't bring back the children!
Of course not, no.
But...
At least I can send him off by their side.
Please... Don't do this.
Don't, please!
Ah... Please... Please!
Ugh, I poured it all on the President.
I should've saved some.
Then...
What... What are you doing?
The punishment that suits you better, not worse.
Finally...
Today we get to see our President off.
Go and get down on your knees in front of the kids.
Else I'll hunt you down again.
No...
No...!
What... Who are you?
What? Oh what?
Who are you, you bastard?
Come here, you bastard! Come here!
(Quiz from God 5: Reboot)
I cannot let him go.
The evidence cannot be clearer!
Ms. Seo In–sook, your lies...
I won't take it anymore.
Jin–woo will recognize me some day, right?
They'll be back. Those nightmarish memories.
Find a cure, within a week.
There really is no cure!
Aren't you full of spirits when death is approaching?
No!
Sang–pil!
