(Episode 10)

This is Yu Dong Man.

You once asked me this.

Whether I'll be a professor or a detective.

And that I'll need to choose one.

Honestly, I thought being a professor...

isn't a bad option.

But I was learning more from the kids.

It was embarrassing.

I thought it'd be better...

to catch the bad guys who are below me...

than to learn from the kids who are better than me.

That's why...

I'm going back to being a detective.

(Professor Yu Dong Man)

(Professor's Office)

It can't be true.

It can't be true.

(Yu Dong Man)

Professor Yu.

Sun Ho.

Is Professor Yu really not in his office?

He left this in my office.

Please tell him when you see him...

that it'll take a week to process his resignation.

(This is Yu Dong Man.)

Professor Seo,

please take good care of those airheads.

You're only 20. You need to love, travel,

and fight.

Enjoy your youth and life.

The investigation isn't everything.

(Professor Yu Dong Man)

(Professor Yu Dong Man)

Please leave a message after the tone.

I didn't call to persuade you to come back,

so make sure you listen to this.

The burner phone that kept calling Mr. Park Chul Jin.

It turned on. And I got the location.

If we go now,

we should be able to catch those jerks in the gambling ring,

so call me.

Or answer your phone!

That burner phone...

It's the scumbag who framed my mom, isn't it?

I totally knew something was up.

Sun Ho always sneaked out at night.

We kept saying we'd never keep secrets from each other.

You liar!

Let's go. You said you have the location.

Okay.

Let's go to Bum Tae's place first.

What?

Come on. As members of the KIU, we can't take a taxi.

What? "KIU"?

Kang Sun Ho's Investigation Unit.

KIU, in short. Don't you remember?

The heroes who solved the exam leak case!

It's us!

Heroes?

Yes, heroes!

- Yes, let's go. - Let's go.

Let's go.

Get up.

- Kang Hee. - You might break down at this rate.

And I won't be able to bear that.

I know that the anger is boiling up inside you.

I know that you're upset.

So say what you have to say when you meet Professor Yu.

"How could you do this without telling me anything?"

"You can't leave like this. You're such a show-off."

"So what if you're a professor?"

Besides, where do you think he went after handing in his resignation?

He must've left to catch the culprit.

I'm sure Professor Yu is where the culprit is.

Let's go.

Stop it already.

Why do you keep calling him when he's not picking up?

So that he can call me back anytime he wants.

He ran away without saying goodbye. It can't be easy for him to call us.

He must be really embarrassed.

That's why I'm giving him a chance.

I'm leaving him room, so he can come back.

Or at least he can call us back.

Where on earth is he?

Who is he?

He's a long-term stay guest.

He doesn't even fish,

and he's always in his room.

Maybe he's a wanted man.

No way.

That can't be.

(Professor Kwon Hyuk Phil, Kang Sun Ho, Professor Choi Hee Soo)

(Go Deok Bae's locations)

I staked out for 48 hours,

and he's nowhere to be seen all of a sudden?

Go Deok Bae, that fatty.

Where on earth is he?

- Hey, how did it go? - Dong Man.

Hey, I'm here.

Excuse me.

The last signal was picked up in Changrin-dong.

Changrin-dong? Isn't that where the international street is?

Yes.

Professor Yu must be somewhere there too, right?

(Money exchange, transfer)

This is where the last signal was picked up.

There are more alleys than I thought.

Why don't we split up and look for him?

No.

Bum Tae and I will go that way.

Wait.

Still, it's...

It's fine. It's still bright, and there are many people.

- Okay. - You two should go that way.

We'll call you when we find Professor Yu.

- Let's go. - See you later.

Do you think the culprit is here?

Now that we're here,

I feel so lost.

What would Professor Yu have done in this situation?

Honestly, I resent him a lot.

He turned himself in and left school as he likes.

He doesn't care about the promise he made to me.

I resent him for acting as he pleases.

But still, I hope he's here.

Shall we go find him?

(Republic of Korea Passport)

It is Professor Go.

Gossi Beer was closed,

so I thought you went on a trip.

Are you okay?

I was just startled...

to see you guys here.

I know. How did we run into you here?

What are you doing here, by the way?

Here?

Oh, I'm here to get some groceries because they sell unique sauce here.

What about you guys?

- We're... - Our classmate, Min Ho, lives here.

- Min Ho? - We're having our lunch here.

Is that so?

The alley over there has a lot of good restaurants.

Okay. Thank you.

- See you when the semester starts. - Okay, enjoy your lunch.

- Bye. - Bye.

What's wrong?

I was going to ask him if he saw Professor Yu.

He seemed a little suspicious.

His clothes...

and bag look suspicious.

Give me your phone.

Dong Man, Go Deok Bae's car was spotted...

in the international street in Changrin-dong.

Gosh, that jerk. Did he flee already?

My gosh.

Why on earth did he come to the international street?

I know, right? Why did it have to be here?

Tell me about it.

I'm sure he's not here for sightseeing.

What's in this area?

Well, they sell tacos, pho, curry, and...

I didn't mean food.

You didn't mean food?

There are many foreigners here,

so there must be many banks and currency exchange booths.

They do illegal transactions in foreign currencies here.

Illegal transactions in foreign currencies?

Exchange booths? That's right!

Gosh.

I must be really lonely to have gone this far.

I'm seeing things now. What a mess.

Professor Go is the culprit?

No way. It can't be.

- He can't be, right? - I have no idea.

He could be here for grocery shopping.

Grocery shopping?

Gossi Beer is closed during summer vacation.

Hey, this is a homemade listening device,

and the maximum transmission range is 3km.

The only person within the distance who'd listen in on our talks...

is Mr. Go!

We don't know that for sure yet.

Professor Yu was right.

What are you talking about?

Which direction did Professor Go go?

He went to that alley.

Let's go then.

What are you guys doing here?

- Professor. - Gosh.

Will it be okay if we stay here?

Hey, didn't you see his fierce eyes?

Okay. It'd be better for us to stay here then.

Right.

Aren't you going to tell me? What are you guys doing here?

What were you doing here then?

What did you say?

Professor Go is the culprit, right?

Gosh, how did you know that?

The burner phone that was used to call Mr. Park was turned on.

We've followed the GPS of that phone,

and we ran into Professor Go here.

What?

Gosh, how did you do that so easily?

No, I mean...

You ran into him? Who did? Was it you?

No.

It wasn't me. Bum Tae and Jun Wook did.

You punk! Did you completely forget about Chul Jin getting hurt?

You dared to come here, and you even brought your friends.

You shouldn't have left if you were worried about it.

You shouldn't have left in the first place,

so we won't have to come here for you.

You trusted and waited for Mr. Park.

Don't you think I can be on your side as well?

How would I trust you when you're acting like this?

Hey. Because you poked around here and there...

without knowing anything,

we only lost track of Professor Go.

Do you think I've been only watching him all this time...

because I couldn't get him?

Do you even know how many days and nights I've been struggling...

to gather clear evidence so that I can get him?

Just take them and go home.

My gosh.

Have you ever thought of me as your partner?

Don't run away and answer me.

Gosh, you punk.

Answer me, mister.

What? "Mister"?

What? You're not even a professor anymore.

Hey, Kang Sun Ho!

The answer to the last question of the Investigation Studies.

The most important element of an investigation.

I wrote "partner" as an answer.

That's what I've learned.

(Partner)

I've only learned that during the six months.

But it's all useless now.

Hey, you punk.

(Yu Dong Man)

Sun Ho...

Gosh.

(Letter of Resignation)

Professor Seo said you have a week before it's processed.

I'll get my mind off of it now,

so do as you wish.

Wait.

My back.

I hurt my back.

- Your back? - My back.

- Are you okay? - Gosh!

Should I take you to the hospital?

I didn't see that coming.

Gosh, it feels like my spine is broken.

I'm sorry, Professor.

My goodness.

You're calling me a professor again?

Well, I got so angry back then.

Why did you submit your resignation and investigate on your own?

You said I was your partner.

Gosh, my back.

Should I head to the hospital now?

There's no need. Just follow the GPS.

If you get to me this fast,

my decision to leave goes to waste.

You must feel ashamed.

But what about it?

What?

Can't a professor feel ashamed?

I've been ashamed countless times.

I was ashamed because I was young and didn't know anything.

When you act like you don't even care about me.

I felt ashamed thinking,

"Was I the only one who thought we were partners?"

So...

this is your last chance.

If you ever do something like this again,

I will never see you again.

Gosh, that's so scary.

- I mean it. - I mean it too, you punk.

Gosh, it hurts.

After hearing about the wanted man,

I felt something obnoxious about him.

So I took a peek.

I saw his face, and it was him.

It was the professor at the Police University...

who came here a couple of times.

You've called the right person. So where is it?

It's the second floor up there.

He left earlier and didn't come back yet.

You can go and take a look.

- Thank you. - No problem.

Gosh.

He said to come here when I'm lonely, and he was here indeed.

(Illegal Gambling Site Opening and Closing Log)

(How do the illegal gambling sites operate?)

What are all these?

Professor Go?

You're here.

Where is Park Chul Jin's stuff?

I've got them already.

You know, Detective Bae.

He likes money so much, and it's kind of tiring.

It doesn't matter as long as the ties are cut off.

Is everything ready for the event?

We've done it many times.

We need a big one before we lie low.

Gosh.

I told you to go home. Why did you guys follow us?

I need to do this investigation.

It's related to my mom's case.

And we even know who the real culprit is.

I can't go back like this.

I need to catch that culprit.

Gosh, you're giving me a headache.

Jun Wook and I ran into Professor Go.

Right. We are in danger.

Our cover is blown.

We can't risk putting our families in danger by going home like this.

Gosh, you're driving me crazy.

Why are you guys doing this to me?

What's that all about?

Let's talk, Professor Yu.

All the documents in your room... What are they for?

Why did you go through my things?

Is the owner of Gossi Beer...

really the culprit who ran the illegal gambling ring?

Yes, I think so.

So the kids chased him and ran into him?

Yes.

What on earth were you thinking?

Why are you yelling at me?

I handed in my resignation to prevent a situation like this.

Are you saying you did nothing wrong?

No. I said that because you suddenly raised your voice at me.

Enough, both of you.

You should've quit investigating it once you became a professor.

What will you do with the kids running around to catch him?

I handed in my resignation to go back to being a detective.

I've done enough!

Enough, both of you.

Forget it. What are you going to do about them now?

I'll take responsibility for everything!

How? What will you do if they get hurt?

I said, enough!

We don't have time for this.

The owner of a pub right by the Police University...

turned out to be the one who ran the gambling ring.

The kids are in danger now.

Do you really want to fight right now?

- What about the police? - We can't tell them.

They have Chul Jin in custody.

Someone else could be in on this.

I'll figure it out on my own.

You'll figure it out? How? With the kids?

We should step in.

What?

We should catch him. Our students are in danger now.

Are you kidding me right now?

Okay. I love you, Dad.

I told my parents that I'm taking summer courses.

All right.

It's not a lie though.

It's like a summer course for Investigation Studies, you know?

What about you, Sun Ho? Have you called your family yet?

I did, earlier.

By the way,

did he start the illegal casino site while working right by our school?

When did he start it?

I wonder too.

He must have made a lot of money.

Why did he keep running Gossi Beer?

In Asan, of all places. This isn't Gangnam.

Who cares about a criminal's history?

I guess he blew all his money on gambling.

By the way, what's taking the professors so long?

I have friends in the force who I can trust.

I told you. We can't get the police involved.

They'll just cut off another tail.

How are the three of us going to arrest those jerks, then?

Three? No.

There are seven of us in total, including the kids.

They're in their first year.

They're still freshmen!

I know. We'll just get their help with the investigation.

The three of us can arrest those jerks.

What?

If you think it'll be hard, you don't have to join us.

I don't want to force you.

I'm sure Professor Choi and I can do it on our own.

Professor Kwon, please.

I think this is wrong.

In my book, this just can't happen.

We should catch him.

Our students are in danger now.

(384N 4178)

Professor Kwon is right.

It's crazy that we're getting the kids involved in this.

You're right.

We may be pushing them deeper into danger, not protecting them.

But wouldn't it be better to keep them in sight?

I get so worried when I don't know where they are.

Anyway, I'll help. That's the right thing to do.

For both you and Professor Kwon,

this will be a long night.

The most important element of an investigation.

I wrote "partner" as an answer.

When you act like you don't even care about me.

I felt ashamed thinking,

"Was I the only one who thought we were partners?"

Did you sleep well?

- Yes. What about you? - Me too.

What a beautiful day.

Hey.

Why are you lying down there?

Gosh, that silly goose.

My goodness.

Don't eat the greens.

It tastes fresh. I like it.

Professor Choi Hee Soo will help us out.

First, let's come up with a solid plan.

We'll work in teams of two.

Sun Ho and I will start...

with searching Gossi Beer, where Go Deok Bae used to stay.

Professor Choi and Kang Hee.

The two of you can...

We'll look into online gambling.

Okay, sounds good.

What about me and Jun Wook? What can we do?

We'll do anything you say, Captain Yu.

Captain? Yes, Captain.

Bum Tae and Jun Wook, you guys can... My goodness.

The two of you can come with me.

Professor Kwon, Bum Tae, and Jun Wook...

will first go and check Changrin-dong,

where Professor Go was spotted yesterday.

Find out why that jerk went there...

and what he did while he was there.

We have a suspect in mind...

but no solid evidence or clues whatsoever.

Our priority is to find solid evidence so we can arrest him.

Put your amazing teamwork to use...

and make sure you bring back results. Okay?

- Yes, sir! - Yes, sir!

Changrin-dong?

So the property register...

says that there's a basement here?

That's right. Get this. It's just a pub,

but their electricity bill says it's for industrial use.

That means he definitely did something else here.

How can we check though?

What?

Are you going to stop me from breaking in again?

No.

These outlaws commit crimes and do all sorts of bad things.

We must put them behind bars.

You little punk.

Did we run into Professor Go around here?

All I see are currency exchange shops.

He must've gone into one of them.

Then let's act like we're customers...

and find out what he bought in this area.

A sting operation is illegal.

We have to do the legwork and gather the info we need.

How would you define a sting operation,

- Noh Bum Tae? - Sorry?

Oh, it's...

I mean, it's...

It uses a trap to catch master criminals and...

Then when is a sting operation allowed to be carried out?

- Cho Jun Wook. - Sorry?

To give them a chance...

Giving a chance and providing an appropriate environment...

who's planning to commit a crime is legal.

Inducing an innocent man to commit a crime...

when he doesn't intend to, then it's illegal.

That's right.

We're only going to specify...

what Professor Go was here to buy.

Is the investigation method we're using...

a sting operation or questioning?

- Questioning... - A sting operation.

- A sting operation! - Questioning!

When I come back,

you'd better be prepared with the answer.

You'll need a basis for your answer as well.

Wait here.

- Yes, sir. - Yes, sir.

- He's so scary. I don't know. - Which one is it?

(Situation Room)

Do you want me to come with you?

It's okay. I'll go on my own.

But...

do you really think your mother knows?

They change the website address dozens of times a day.

They repeatedly open the site and close it.

Do you think I have brains for that?

Yes. A thief knows thieves best,

and my mom knows about that best.

I'll be right back.

(Articles on checking ID)

Gosh.

Darn it.

Look!

- Oh, gosh. - Goodness.

There's no way a basement is there.

They always...

hide it thoroughly.

It could be behind the mirror.

No, it's not.

That's right! Underneath the carpet.

If you remove it,

there could be something...

It's just a regular floor.

Hey, what's that?

Gosh, what is this?

Goodness.

My gosh.

This darn jerk.

They actually operated the site here.

How could they run it right in front of the school?

You can't see what's right under your own nose.

They must've moved their base somewhere else, right?

Of course.

Gamblers can't quit gambling that easily.

It's your first time seeing me in my uniform.

Why aren't you saying anything?

It's not my first time, you wench.

I saw you in it during my trial.

- You saw me? - Of course.

You were glaring at me, so how could I have missed that?

Whatever. I have something to ask you.

Remember what you said last time I was here?

About the illegal gambling gang.

You said they repeatedly open...

and close the site.

Why you little...

Why do you keep bringing that up?

I must figure this out, that's why.

Then how do you know it's the same site...

when they open a new one?

Leave. You should go.

I got in danger while chasing the illegal gambling gang...

to help solve your case.

So...

I need your help.

Which crazy punk...

dared to touch my daughter?

They must be dying to be beaten by me.

Not even the Almighty...

can touch my daughter. There's no way!

Why...

Why would you want to fight with the Almighty?

So what if it's the Almighty?

I'll fight with anyone who messes with you.

So you need to pull yourself together.

You are...

the daughter of the nasty Oh Jung Ja.

You're way smarter than me,

and you're so much better than me!

What can I do for you?

(Articles on checking ID)

Let's go.

It's me.

Can't you tell from my voice? I'm Ms. Oh!

Find out where Chewing Gum is within an hour.

This is what happened in the exchange office...

of Changrin-dong.

Are you Korean?

Money exchange?

Got it.

You're here for money laundering? Illegal transaction?

What are illegal transactions?

According to Article 16 of the Foreign Exchange Control Act...

Gosh, I'm so sleepy.

Just move on. So what happened?

What do you want? Private loan?

I heard you guys provide other services.

Other services?

Yes. Don't worry about the money.

Just name the price.

What do you think he wants?

Maybe a forged passport or a burner phone?

He can't be a cop, can he?

Hey, he doesn't look like a cop at all.

He's obviously like one of us.

Forged passport, a burner phone.

Is that all you can provide?

- Are you... - Are you Japanese?

A forged passport and a burner phone?

Is he planning to flee the country?

Yes, but he's going to go on a spree first.

I talked with my mom on the phone.

There's this woman called Chewing Gum...

who betrayed my mom.

Anyway,

she's the VIP customer of the illegal gambling gang we're after.

- And? - They sent out invitations...

to the VIP customers to their newly opened site,

saying they're having an event to celebrate it.

Twice as much chance of winning a jackpot.

Let's go meet Chewing Gum.

Be careful.

Professor, can I talk to you?

As long as we can access the site,

I can track down their IP address right away.

If we find their address and catch them red-handed,

we'll be able to arrest Professor Go too.

Gosh, you.

Just go around and tell everyone that you're a hacker.

Then what else can we do?

Yoon has a backtracking program, not you.

I do.

But it's for backtracking online accounts,

so I'll need to code the program again...

to track their IP address.

It'll take some time.

- How long? - Two days.

Finish it by tomorrow.

Tomorrow? I told you I need at least two days.

Code it with all your might.

Then you can do it.

Even with all my might, I can't do it here.

Darn it.

On the phone, you'll see a text message with a link.

Check the link and get rid of the phone.

Then what will you do?

I'll just get a new phone.

At my mom's trial, you gave an incriminating statement.

So why are you trying to help me now?

I saw your mother cry.

So much for being a mother.

Pay for my coffee too.

I can use the LAN cable here,

so it'll be faster to code it here.

Okay, then let's get started.

(To: Sun Ho)

(Under Construction)

The site isn't up and running yet.

But I can use this to track them.

I'll code the program before they go live and get their IP address.

Okay. With the IP address, we can find out where they are,

so we can raid them as soon as the site goes live.

Yes.

These scumbags...

Professor Yu and Sun Ho...

are out checking something. They'll be back tomorrow,

so don't stay up and wait for them.

Okay.

Oh, and...

that woman was wrong.

- Sorry? - You aren't a nuisance to your mom.

She should be grateful to have a daughter like you, if anything.

Tell her you're all she has.

So be proud and sleep well with a smile on your face.

You were amazing today, and you did an excellent job.

Good night.

Life is a comedy.

We're figuring out how to catch them in the very space...

where they used to do the illegal deeds.

When you caught me and took me to the police station,

I really didn't know I'd end up at the Police University with you.

You'll return to school...

once the investigation is over, right?

That will depend on how you behave.

Why are you being so difficult?

Girls never play hard to get if they don't like the guy.

What?

I'm not sleeping,

so you'd better not slack off.

(Data Generation Completed)

Let's get started, Bird.

(Are you sure you want to run the program?)

Can we begin now?

Yes.

Okay.

(Are you sure you want to run the program?)

There are two escape routes, here and here.

Professor Choi, we'll each take one.

The site will go live at 21:00 tonight.

We'll raid them as soon as the site goes live.

The four of you...

should stay here and monitor everything.

We're not going with you?

Information and speed are the keys to solving cybercrime cases.

If the server goes down, or if the database is destroyed,

the evidence will be gone, so we can't arrest them.

That's why we need you guys to stay here...

and monitor everything until we arrest all of them.

Let us know if you notice anything suspicious.

Will do.

But do you really need all four of us to do it?

Yes, all four of us should probably do it together.

No mistakes are allowed.

Let's not waste our time. We won't lose them.

We will catch them tonight, no matter what.

- Yes, sir! - Yes, sir!

Is it done?

All the setup has been completed.

The site will go live...

in six hours.

By the way, who figured out the IP address for us?

Someone I know.

A hacker who's been helping me since my detective days.

Where's Professor Kwon?

He went to pick up some dinner for the kids.

This must be stressful for him, right?

He does everything by the book, you know.

But right now, he's going against...

all the rules and principles that he had set for himself.

But you know,

should rules matter...

when dealing with someone who did such a thing...

right in front of the Police University?

Honestly, I don't even know how we got here,

but when I actually see Professor Go later today,

I won't even know what to say.

I'm beginning to understand how you must've felt...

when you saw Chul Jin.

Let's go for a drive like we said after this is all over.

Then don't you dare sprain your ankle...

or get a single scratch on your face today,

so we can both look good...

on our date.

Professor.

I have something to tell you.

Is it going to rain?

They said it'd be sunny today.

The site will go live in just an hour.

Okay, let's go.

Make sure to call me if something comes up.

Professor Choi, be careful.

Don't you know I was on the national judo team?

They should be the ones to watch out for.

- Professor Kwon. - Professor Kwon.

Forget it.

When I come back, you'd better be prepared...

with the answer and the basis for it.

I'll be right back.

You should stay out of it when we arrest them.

Only Professor Yu and I have the authority to investigate.

I have two veterans with me. I'm not worried at all.

Let's just be done with it.

What's happening? They're deleting the data.

- What? - Let me see.

- What is it? - They're not there.

You should block the escape routes first.

- I'll go and check their base. - Okay.

Professor Choi's line is busy.

Professor Kwon isn't picking up.

What about Professor Yu?

I'll call him again.

Why are they not picking up?

Yes. We should finish it before that.

Okay. Got it.

Hurry up!

How many more minutes until it blows up?

Ten minutes.

We have ten minutes left.

I'll be out of the country once things get sorted out.

Yes, Professor.

Wrap this up.

I'll see you in Thailand.

Yes, I'm on my way, so get the boat ready.

Okay.

I got you, you little punk.

Surprised, aren't you?

Darn it.

(Kang Sun Ho)

- What is it? - She's not picking up.

We got the wrong place.

They're running a program to blow up the site.

The firewall went down, and I got their final IP address.

A program to self-destruct the site?

I think they found out that we hacked them.

There's no way our information leaked though.

The others might be in danger,

so I'll get going alone.

- Hey! You punk! - Professor Yu.

You should hurry.

Gosh.

Professor Yu!

Professor Yu, are you okay?

Darn it!

Why you...

Who are you trying to mess with, you jerk?

Darn it!

Darn it!

Let go of me!

- Run! - Hurry!

- Block the route! - Spread out!

Go Deok Bae, you're under arrest...

for running an illegal gambling house,

violating the Promotion Act on Game Industry,

the Electronic Financial Transaction Act,

the Act on Regulation and Punishment of Criminal Proceeds Concealment,

the Telecommunications Business Act,

and the Act on Information and Communications Network...

Utilization and Information Protection.

You have a right to an attorney.

You have the right to remain silent...

and the right to explain yourself.

You also have the right to challenge the legality...

of your confinement.

But just don't. You're dead meat now.

(Police University)

To celebrate the success of our first investigation,

- we came to the beach! - We came to the beach!

Have a great time.

There's no bus to Seoul here.

Those crazy punks!

- What is that? - A gift for my boyfriend.

I love it so much.

Stand tall, you punk!

It's just money that we don't have, so stand tall!

- What are you talking about? - What do you think?

Good luck!

I'm here to meet Han Jung Sik, the head of Investigation.

I hope that was the last time you pull off a dangerous stunt...

with our students.

How did you know I arrested them with the kids?

You're finally here, Yoon.

How do you think a hacker ended up in the Police University?
