[Ena] The One City unit 5802.

5
00:00:38,197 --> 00:00:42,001
The only link the three murder victims
had in common.

6
00:00:52,992 --> 00:00:56,460
The last owner of the apartment
was Miyoung Lee.

7
00:01:07,159 --> 00:01:10,629
The previous owner was Chimok Kang.

[bubblegum pops]

9
00:01:34,199 --> 00:01:39,047
And the first owner of the apartment
was Yoonsu Do.

10
00:01:49,704 --> 00:01:51,416
He was allotted 13 units

11
00:01:51,501 --> 00:01:54,384
during the preliminary distribution
for The One City.

12
00:01:54,467 --> 00:01:57,476
Unit 5802 was one of those units.

13
00:01:58,898 --> 00:02:01,949
Currently, the remaining 12 units
are owned by his family.

14
00:02:03,620 --> 00:02:06,630
So why did he hand this unit over
to Chimok Kang?

15
00:02:07,842 --> 00:02:11,561
And also, where in the world
did all of this begin?

00:03:39,993 --> 00:03:42,457
Chimok Kang and Miyoung Lee
were engaged to each other,

19
00:03:42,542 --> 00:03:44,171
so that kinda makes sense.

20
00:03:44,841 --> 00:03:48,602
There has to be a reason
why Yoonsu handed the unit over to Chimok.

21
00:03:49,521 --> 00:03:51,443
Is there a secret connection there?

22
00:03:51,527 --> 00:03:56,166
Unit 5802 was never involved
in any type of lawsuits or accidents,

23
00:03:56,249 --> 00:04:00,345
but what's strange to me is how quickly
its ownership kept changing hands.

24
00:04:00,428 --> 00:04:02,560
Yoonsu Do was the first owner.

25
00:04:02,644 --> 00:04:04,859
Then it was transferred to Chimok
two months later.

26
00:04:04,943 --> 00:04:07,074
One month after that,
Miyoung Lee took ownership.

27
00:04:07,157 --> 00:04:09,038
Almost as if they had agreed to it.

28
00:04:09,121 --> 00:04:11,504
What would make them
trade an apartment like that?

29
00:04:12,967 --> 00:04:15,557
You said that Donghoon Yoon,
Miyoung Lee and Chimok Kang

30
00:04:15,641 --> 00:04:18,650
could have been the culprits,
not the victims, is that right?

31
00:04:18,733 --> 00:04:20,824
What if the four of them,
including Yoonsu Do,

32
00:04:20,907 --> 00:04:22,285
committed a crime together,

33
00:04:22,369 --> 00:04:24,961
and then in exchange,
they were given the apartment?

34
00:04:25,044 --> 00:04:27,845
So then the apartment was used
like some kind of payment.

35
00:04:30,435 --> 00:04:31,438

36
00:04:34,155 --> 00:04:35,659

00:04:36,830 --> 00:04:38,543
my uncle wasn't included in that?

38
00:04:39,462 --> 00:04:41,384
Why aren't they connected to my uncle?

39
00:04:42,137 --> 00:04:45,229
There's gotta be a reason
my uncle was the first to die.

40
00:04:46,650 --> 00:04:48,740
The Hangang Police Station is the link.

41
00:04:49,701 --> 00:04:52,125
The One City is under its jurisdiction,

42
00:04:52,209 --> 00:04:55,051
and Donghoon Yoon
was the superintendent there for a year.

43
00:04:56,304 --> 00:04:58,268
Did Superintendent Yoon sweep a case

44
00:04:58,352 --> 00:05:01,277
that was somehow related to The One City
under the rug?

45
00:05:02,615 --> 00:05:04,538

What do you suppose he got in exchange?

51
00:05:26,938 --> 00:05:29,236
A crime committed by four individuals…

52
00:05:31,619 --> 00:05:32,622
Yoonsu Do

53
00:05:32,705 --> 00:05:36,299
was a clown who stepped all over
the sandcastle the children made.

54

Chimok Kang wore an armband and danced.

shot a doll shaped like a person.

00:12:57,580 --> 00:12:59,418
Mmm… Good talk.

179
00:12:59,503 --> 00:13:00,839
Yeah.

180
00:13:07,191 --> 00:13:09,239
[door opens, closes]

181
00:13:10,995 --> 00:13:13,837
You saw Miyoung's Lee car
on the day that she was killed?

182
00:13:15,090 --> 00:13:16,093
[Sgt. Nam] Yeah.

183
00:13:18,643 --> 00:13:20,105
I remember because…

184
00:13:23,072 --> 00:13:25,203
The Porsche Panamera's my dream car,

185
00:13:25,915 --> 00:13:28,087
so they stick in my mind
whenever I see one.

186
00:13:29,801 --> 00:13:32,977
The weird thing about that night
is the driver floored it at a red light.

187
00:13:33,730 --> 00:13:36,153
She must have seen us
parked on the side though.

188
00:13:38,494 --> 00:13:41,504
It was almost 10:00 at night,
and the road was empty.

189
00:13:41,587 --> 00:13:42,924
so I didn't go after her.

190
00:13:44,094 --> 00:13:48,106
[♪ pensive percussive music]

191
00:13:48,692 --> 00:13:50,823
But I keep thinking if I had stopped her…

192
00:13:53,998 --> 00:13:56,632
then maybe I could've prevented
what happened to her.

193
00:13:59,975 --> 00:14:01,689
It's really hard to let it go.

194
00:14:02,692 --> 00:14:05,282
She knew that the police car was there,

195
00:14:05,366 --> 00:14:06,996
so what could have made her do that?

196
00:14:07,079 --> 00:14:09,294
Why'd she step on the gas
and run that light?

197
00:14:10,966 --> 00:14:12,136
Yeah.

198
00:14:12,219 --> 00:14:13,641
You're right.

199
00:14:13,725 --> 00:14:15,438
She ran the light on purpose.

200
00:14:15,981 --> 00:14:17,444
That's because running that light

201
00:14:17,528 --> 00:14:20,662
was her best attempt at signaling for help
when she saw your patrol car.

202
00:14:23,880 --> 00:14:27,767
So do you, uh… remember anything else
about it or see anything

203
00:14:27,850 --> 00:14:29,606
in the back seat or the trunk?

204
00:14:31,821 --> 00:14:33,827
Uh… No, uh…

205
00:14:35,038 --> 00:14:37,044
The windows were heavily tinted.

206
00:14:37,630 --> 00:14:38,883
Hmm…

207
00:14:39,803 --> 00:14:41,642
Too bad. Thanks, anyway.

208
00:14:50,961 --> 00:14:52,884
Even if you had stopped the car,

209
00:14:52,967 --> 00:14:55,056
nothing would have changed
what happened to her.

210
00:14:57,773 --> 00:15:00,363
It's probably going to take a while
to overcome that guilt,

211
00:15:01,199 --> 00:15:03,331
so let's not beat ourselves up
too much about it.

212
00:15:14,430 --> 00:15:15,266
I'm here.

213
00:15:16,771 --> 00:15:18,651
Hey, why don't you ever
pick up your phone?

214
00:15:18,735 --> 00:15:21,201
Oh, look who's talking.
You didn't pick up either.

215
00:15:21,912 --> 00:15:23,876
[sighs] Yeah, whatever.

216
00:15:23,960 --> 00:15:26,132
I was talking to Dongsu Tae
when you called.

217
00:15:28,514 --> 00:15:29,894
So, uh…

218
00:15:30,814 --> 00:15:32,484
How well did you know your uncle?

219
00:15:36,747 --> 00:15:41,762
[♪ mellow music]

220
00:15:51,374 --> 00:15:54,050
I always thought that he quit the force
because of me.

221
00:15:56,139 --> 00:15:59,690
My uncle was apparently a model officer
and well-respected.

222
00:16:01,404 --> 00:16:03,829
So what kind of case
could he have swept under the rug?

223
00:16:03,913 --> 00:16:05,583
You never know with people.

224
00:16:07,255 --> 00:16:11,351
It's possible that he swept
more than one case under the rug.

225
00:16:16,741 --> 00:16:18,080
Think you can do this?

226
00:16:19,708 --> 00:16:21,714
Do you think you can face those cases?

227
00:16:23,848 --> 00:16:25,769
I'm asking Lieutenant Ena Yoon…

228
00:16:26,479 --> 00:16:29,530
the profiler,
if she can analyze these cases.

229
00:16:33,836 --> 00:16:34,922
I have to.

230
00:16:35,006 --> 00:16:36,845
I asked, "Can you?"

231
00:16:40,271 --> 00:16:41,274
[sighs]

232
00:16:44,952 --> 00:16:45,955
Mm.

233
00:16:50,259 --> 00:16:51,596
Then let's dig.

234
00:16:53,352 --> 00:16:57,072
A case with a shooting,
one with deceptive whispers,

235
00:16:57,155 --> 00:17:00,581
one that had armband wearing thugs
and a broken sandcastle.

236
00:17:01,125 --> 00:17:02,170
That right?

237
00:17:03,382 --> 00:17:04,385
[chuckles]

238
00:17:06,349 --> 00:17:07,980
[♪ uplifting music]

239
00:17:08,063 --> 00:17:11,364
[phone buzzing]

240
00:17:17,465 --> 00:17:19,013
[sighs] Yeah, what is it?

241
00:17:19,096 --> 00:17:20,852
Everything okay at the station?

242
00:17:21,561 --> 00:17:23,525
Why do you suddenly want to know?

243
00:17:24,361 --> 00:17:27,203
You should remember
that I rank higher than you, you dick.

244
00:17:27,287 --> 00:17:29,376
Look, Hansaem stopped by.

245
00:17:31,049 --> 00:17:33,096
He was asking about Donghoon.

246
00:17:33,180 --> 00:17:35,812
[Hogeun] Not the first time
that punk did that. Who cares?

247
00:17:36,522 --> 00:17:37,818
So, what's bothering you?

248
00:17:38,403 --> 00:17:41,873
You know that report you showed me?
The profile that Ena made?

249
00:17:45,007 --> 00:17:46,427
I was wondering…

250
00:17:46,511 --> 00:17:49,269
what's the real reason you think
that Donghoon died?

251
00:17:52,906 --> 00:17:53,951
[sighs heavily]

252
00:17:55,496 --> 00:17:56,541
[Hansaem] I got one.

253
00:17:57,419 --> 00:17:58,422
"Myungsung Daily defamation case"

254
00:17:58,505 --> 00:17:59,508
"No prosecution
(acquitted due to lack of evidence)"

255
00:17:59,591 --> 00:18:01,514
The victim's family
took the Myungsung Daily

256
00:18:01,597 --> 00:18:04,858
and the journalist who wrote the article
to court for defamation, and look…

257
00:18:05,401 --> 00:18:07,323
The case was thrown out
after three months.

258
00:18:10,792 --> 00:18:13,508
The plaintiff was the younger sibling
of the last victim

259
00:18:13,592 --> 00:18:15,306
in the Jungbu serial murder case.

260
00:18:16,392 --> 00:18:19,735
Coincidentally, this case was why
Superintendent Donghoon Yoon

261
00:18:19,819 --> 00:18:21,073
suddenly quit the force.

262
00:18:23,079 --> 00:18:26,883
This defamation suit must have been
the last case he helped cover up.

263
00:18:26,966 --> 00:18:29,056
We should dig into this one first.

264
00:18:29,139 --> 00:18:30,895
If our theory is correct, then a victim

265
00:18:30,978 --> 00:18:33,946
whose life was ruined by the case
Superintendent Yoon made disappear

266
00:18:34,029 --> 00:18:36,661
is the one going around
killing people right now.

267
00:18:36,744 --> 00:18:39,044
They're the victim and also the murderer.

268
00:18:40,297 --> 00:18:42,137
-Let's go.
-Hey, hold on.

269
00:18:44,226 --> 00:18:46,065
I've got something to tell you.

270
00:18:49,826 --> 00:18:51,122
A handkerchief?

271
00:18:51,706 --> 00:18:55,301
I heard it was an old, plain-looking
handkerchief that old men tend to use.

272
00:18:56,012 --> 00:18:59,396
San Choi, who arrived on the scene first,
saw it and then it disappeared.

273
00:19:00,399 --> 00:19:02,823
It's not in any of the photos
of the scene.

274
00:19:02,907 --> 00:19:05,539
Me, San and the captain
are the only ones who know.

275
00:19:07,086 --> 00:19:08,423
So the killer…

276
00:19:09,426 --> 00:19:11,265
or an accomplice might be among us.

277
00:19:13,647 --> 00:19:15,069
Why are you telling me this now?

278
00:19:16,030 --> 00:19:17,158
Well, that's 'cause you--

279
00:19:17,241 --> 00:19:18,662
Do you trust those guys?

280
00:19:20,919 --> 00:19:22,883
-Huh?
-Do you trust San Choi?

281
00:19:25,307 --> 00:19:26,560
Yeah, I mean…

282
00:19:26,644 --> 00:19:29,027
-And the captain?
-As far as I'm concerned,

283
00:19:29,111 --> 00:19:32,412
no one in Hangang Police Station
is above suspicion, not even me.

284
00:19:32,998 --> 00:19:34,626
But it's not Jungho Yang.

285
00:19:36,173 --> 00:19:38,054
Do you think you can do it?

286
00:19:38,138 --> 00:19:39,474
Do what?

287
00:19:39,558 --> 00:19:42,943
Just tell me,
are you able to look into these guys?

288
00:19:43,028 --> 00:19:45,617
I'm asking whether
you can properly analyze them

289
00:19:45,701 --> 00:19:47,415
as Lieutenant Hansaem Kim?

290
00:19:48,961 --> 00:19:50,591
Think I need a new career?

291
00:19:50,674 --> 00:19:52,263
[scoffs] You still don't know me.

292
00:19:52,347 --> 00:19:55,439
Whoa, what? You gonna blow your lid?

293
00:19:55,522 --> 00:19:58,323
And just remember,
don't take that lid off in front of me.

294
00:19:58,406 --> 00:19:59,952
Stop screwing around.

She was that serial killer's victim.

It's been 20 years already.

303
00:20:33,971 --> 00:20:35,684
[Ena] We totally understand.

00:20:35,767 --> 00:20:37,565
You must have felt really angry.

305
00:20:38,568 --> 00:20:40,240
That's why you sued them, isn't it?

306
00:20:40,324 --> 00:20:42,956
Wouldn't you have to? [sniffles]

307
00:20:43,041 --> 00:20:46,007
If they had caught that son-of-a-bitch
on time, then my…

308
00:20:47,345 --> 00:20:48,473
my sister…

309
00:20:49,184 --> 00:20:52,025
wouldn't have died
when she was only 25 years old.

[shuddering]

311
00:20:55,954 --> 00:20:58,086
Then, that motherfucker
from Myungsung Daily

312
00:20:58,169 --> 00:21:01,553
went around spouting fucking bullshit
about how my sister was a karaoke girl.

313
00:21:02,265 --> 00:21:04,104
She wasn't a karaoke girl.

314
00:21:04,855 --> 00:21:06,820
She went to karaoke

315
00:21:06,903 --> 00:21:08,741
'cause it was her birthday that day.

316
00:21:09,286 --> 00:21:10,957
And she was on her way back home…

317
00:21:12,002 --> 00:21:14,008
I was so fucking angry, you know.

318
00:21:14,092 --> 00:21:16,348
How could they write an article like that

319
00:21:16,432 --> 00:21:18,020
without fact-checking anything?

320
00:21:20,193 --> 00:21:22,241
That's why I sued them for defamation.

321
00:21:24,790 --> 00:21:27,465
Then that dick at the Hangang
Police Station buried the case.

322
00:21:29,554 --> 00:21:30,975
I heard he wound up dead.

Superintendent Yoon is dead too?

-Hey, Ena.
-Hmm?

[♪ dramatic guitar music]

356
00:23:44,250 --> 00:23:46,924
That's from eight months
before your uncle was killed.

357
00:23:49,933 --> 00:23:50,936
[soft gasp]

358
00:23:52,399 --> 00:23:54,447
So my uncle's death wasn't the first case.

359
00:23:54,530 --> 00:23:56,536
Ganghyun Lee was the first one.

360
00:24:00,130 --> 00:24:02,889
Ugh, why didn't I ever
think of this possibility?

[exhales sharply]

362
00:24:11,623 --> 00:24:13,922
Actually, I always thought
it was a little weird.

363
00:24:14,005 --> 00:24:16,220
Even a serial killer who killed 21 people

364
00:24:16,304 --> 00:24:19,982
had to return to their first crime scene
because they left their jackknife behind.

365
00:24:20,065 --> 00:24:22,824
It's impossible for a killer's first run
to go perfectly.

366
00:24:22,907 --> 00:24:25,540
They're bound to make amateur mistakes
and leave some trace.

367
00:24:25,623 --> 00:24:26,961
The scene of my uncle's murder

368
00:24:27,044 --> 00:24:29,594
was way too perfect for it
to have been their first one.

369
00:24:29,677 --> 00:24:33,647
They left no prints, no DNA,
there was nothing left at the scene. How?

370
00:24:34,442 --> 00:24:35,821
Because they'd done it before.

371
00:24:35,905 --> 00:24:37,994
Because Ganghyun Lee
was their first victim.

372
00:24:38,077 --> 00:24:40,878
We might get some clues
if we look back at that case.

Donghoon Yoon and Miyoung Lee.

391
00:25:50,378 --> 00:25:53,177
Chimok Kang and Yoonsu Do's deaths
also had to do with this.

392
00:25:53,261 --> 00:25:55,225
And we caught Chimok Kang's killer.

393
00:25:55,308 --> 00:25:57,148
Yes, but then we got a puzzle piece.

394
00:25:58,360 --> 00:26:00,323
Which probably means he was a target.

You're the first person I've told this to.

There's one piece
we haven't confirmed yet,

399

but we'll go public with everything
once we do.

This case is too big.

But…

402
00:26:22,181 --> 00:26:25,232
I don't think it's a good idea
to go public without all the evidence.

We don't know which one of us
took the handkerchief.

And most of all,

406
00:26:31,208 --> 00:26:32,880
there's Lieutenant Yoon.

407
00:26:33,715 --> 00:26:35,973
Remember I asked whether
you could trust her or not?

408
00:26:37,142 --> 00:26:38,856
Do you know everything about her?

What are you talking about?

411
00:26:43,119 --> 00:26:45,459
From that response,
I'll assume that you don't.

412
00:26:46,964 --> 00:26:48,385
You should ask her yourself.

You've got no right to sit anyway.

at Yangseo Station

00:27:34,899 --> 00:27:38,870

the killer in the Yoonsu Do case.

I'd like an explanation.

428
00:27:50,906 --> 00:27:52,953
It's a bit too soon to tell you anything.

429
00:27:53,663 --> 00:27:54,666

Do you report to me or not?

Huh?

434
00:28:07,329 --> 00:28:11,592
I believe the Yoonsu Do case is linked to
the Ganghyun Lee case from 10 years ago.

435
00:28:11,676 --> 00:28:15,103
Same for the Miyoung Lee, Chimok Kang
and Donghoon Yoon cases.

436
00:28:17,820 --> 00:28:20,368
I also have a hunch
that our Hangang Police Station

437
00:28:20,451 --> 00:28:22,542
may be at the center of this whole case.

00:28:22,625 --> 00:28:23,628
Somehow.

We did conclude that it was a suicide,

but to be honest, I had my doubts.

455
00:29:36,277 --> 00:29:38,618
The man died
with a plastic bag over his face,

456
00:29:38,703 --> 00:29:40,959
which I thought was weird.

457
00:29:41,042 --> 00:29:43,382
People usually don't
kill themselves like that.

458
00:29:43,466 --> 00:29:45,472
Why didn't you conduct an autopsy?

459
00:29:45,556 --> 00:29:48,188
It's not that we didn't want to,
we weren't allowed.

460
00:29:48,272 --> 00:29:50,361
His family was strongly opposed to it.

461

Ganghyun Lee…

462
00:29:54,123 --> 00:29:55,502
lived with his son.

463
00:29:55,586 --> 00:29:57,718
After his divorce,
he was left with the kid.

464
00:29:58,470 --> 00:30:01,980
Apparently, he was depressed
and hooked on booze and sleeping pills.

465
00:30:04,028 --> 00:30:05,406
Then the day before his death,

466
00:30:05,491 --> 00:30:08,457
he told a friend of his
he was struggling to raise a kid alone

467
00:30:08,541 --> 00:30:10,715
and that he wanted to die, so…

468
00:30:11,509 --> 00:30:13,598
he did have a reason to commit suicide.

like it was put there on purpose.

I mean, you always find random shit
at crime scenes, but…

But then he was assigned to
the Investigation Unit at headquarters,

502

To be honest, Jungho did most of the work

anything else you remember?

530
00:33:29,686 --> 00:33:32,110
Did you see anyone
who was acting a bit strange?

531
00:33:32,737 --> 00:33:35,788
Well, uh, the scene was really chaotic,
so, uh…

532
00:33:36,372 --> 00:33:38,336
what I told Lieutenant Kim was all I saw.

533
00:33:39,506 --> 00:33:41,637

Hyung.

546
00:34:36,010 --> 00:34:38,516
Do you know when I admired you the most?

547
00:34:40,314 --> 00:34:43,031
Sure, the fact that you volunteer
at the orphanage once a month

548
00:34:43,114 --> 00:34:44,534
is worthy of respect,

549
00:34:44,618 --> 00:34:47,543
but that could just be because
you're from an orphanage yourself.

550
00:34:49,507 --> 00:34:51,555
You said you had something to report?

551
00:34:52,558 --> 00:34:53,645
So…

552
00:34:53,729 --> 00:34:56,403
back when you first joined our unit
as the captain,

553
00:34:57,323 --> 00:34:59,831
you said that you had
to attend a victim's funeral,

554
00:34:59,915 --> 00:35:02,714
so I asked you why you had to go.
Do you remember that day?

555
00:35:06,475 --> 00:35:07,603
And then you said…

556
00:35:09,903 --> 00:35:11,909
that you had to go apologize to them.

557
00:35:13,664 --> 00:35:16,673
You said it was a cop's job
to protect people,

558
00:35:16,756 --> 00:35:18,302
and that you had fallen short.

559
00:35:19,765 --> 00:35:22,189
You said you had to tell them
you'd catch the culprit.

560
00:35:23,151 --> 00:35:24,697
And that was when…

561
00:35:26,035 --> 00:35:27,455
I admired you the most.

562
00:35:29,880 --> 00:35:31,718
Me? I just enjoy solving cases.

563
00:35:31,802 --> 00:35:34,895

565
00:35:36,148 --> 00:35:37,862
But you had a different start.

566
00:35:39,910 --> 00:35:42,541
I've never seen a cop
with as strong a sense of duty.

567

[exhales incredulously] You know,

568
00:35:44,799 --> 00:35:46,428
I thought you were born to be a cop.

You're a man with a warm heart.

Jungho Yang, he stands for justice.

That's why I call you Batman,
you know? [laughs]

573
00:35:59,634 --> 00:36:01,598
You mind telling me the point of all this?

574
00:36:01,683 --> 00:36:03,857
So why didn't you tell me anything then?

575
00:36:05,569 --> 00:36:08,161
You were the detective in charge
of the Ganghyun Lee case,

576
00:36:08,244 --> 00:36:10,333
and a puzzle piece was found on the scene.

577
00:36:12,089 --> 00:36:14,805
That was the case where the puzzle murders
first started, yeah?

578
00:36:16,686 --> 00:36:19,193
So I really wanna know
why you didn't say anything.

00:36:32,024 --> 00:36:34,322
Were you the one who took
the handkerchief, Captain?

581
00:36:37,289 --> 00:36:38,292
You know me.

582
00:36:38,376 --> 00:36:39,420
Was it you?

583
00:36:39,504 --> 00:36:41,134
Why would I?

584
00:36:42,932 --> 00:36:45,605
If you didn't,
then why wouldn't you tell me anything?

585
00:36:49,702 --> 00:36:52,126
Why do you think I didn't say anything?

586
00:36:52,209 --> 00:36:53,337
Don't know.

587
00:36:55,176 --> 00:36:56,179
I asked you

588
00:36:57,182 --> 00:36:59,732
whether you knew
everything about Ena Yoon.

589
00:36:59,815 --> 00:37:01,236

That's the unit where Ganghyun died.

593
00:37:11,600 --> 00:37:12,687
That day,

594
00:37:13,439 --> 00:37:16,198
do you know who was in unit 314,
directly above?

596
00:37:21,965 --> 00:37:23,887

597

and three of his friends.

598
00:37:25,977 --> 00:37:28,109
Seulgi Cho, Yeonghun Oh…

599
00:37:30,115 --> 00:37:31,535
and Ena Yoon.

600
00:37:35,213 --> 00:37:36,717
It was winter break

601
00:37:37,386 --> 00:37:40,729
and Ganghyun's son's friend hosted
a math study group at his house.

602
00:37:41,481 --> 00:37:43,864
The study group went
from 9 p.m. until midnight.

603
00:37:44,867 --> 00:37:48,210
and camera footage showed
everyone leaving at 12:05 a.m.

604
00:37:49,715 --> 00:37:51,888
Everyone, except for Ena Yoon.

605
00:37:52,891 --> 00:37:54,020
Why?

606
00:37:54,103 --> 00:37:56,819
She claimed she went home at 11
'cause she wasn't feeling well.

607
00:37:57,529 --> 00:38:00,121
But you see, Ena didn't leave
the apartment at that time.

608
00:38:01,333 --> 00:38:03,130
She didn't appear on camera

609
00:38:03,798 --> 00:38:06,891
until over an hour later at 12:23.

610
00:38:11,154 --> 00:38:14,790
Ganghyun's estimated time of death
was between 10 p.m. and midnight.

611
00:38:15,834 --> 00:38:18,677
The day he died,
Ena Yoon's alibi was unclear.

612
00:38:20,473 --> 00:38:21,936
However, I couldn't meet her.

613
00:38:23,107 --> 00:38:25,113
Her uncle wouldn't let me interview her.

614
00:38:25,948 --> 00:38:27,662
According to Superintendent Yoon,

615
00:38:28,330 --> 00:38:31,381
Ena felt unwell.
She went to the rooftop to get some air.

616
00:38:32,217 --> 00:38:35,143
He said she stayed there
till the study session ended.

617
00:38:36,731 --> 00:38:38,611
Do you think that makes any sense?

618
00:38:39,488 --> 00:38:41,997
I wanted to dig deeper
into the Ganghyun case,

619
00:38:42,080 --> 00:38:44,503
then I was suddenly
transferred to headquarters.

620
00:38:47,805 --> 00:38:49,268
Then eight months later,

621
00:38:51,191 --> 00:38:52,987
Superintendent Yoon was killed.

622
00:38:53,072 --> 00:38:54,158
And just like before,

623
00:38:55,411 --> 00:38:57,209
Ena Yoon's alibi was unclear.

624
00:39:00,678 --> 00:39:03,227

now that you know?

That was the last time

665
00:41:43,113 --> 00:41:45,244
I ever saw Ganghyun Lee.

666
00:41:45,327 --> 00:41:49,674
[tutor] We've established that variance
is npq, and that q equals one minus p.

667
00:41:49,757 --> 00:41:53,143
The square root of the positive number
gets you the standard deviation.

668
00:41:53,226 --> 00:41:54,899
Now, let's look at the problem.

669
00:41:54,982 --> 00:41:57,991
What's the mean and standard deviation
of 2x minus 5?

670
00:41:58,074 --> 00:42:00,874
What does the mean
of 2x minus 5 look like?

671
00:42:00,958 --> 00:42:03,256
It's 2x minus 5,

672
00:42:03,340 --> 00:42:05,555
but we can multiply it by two

673
00:42:05,639 --> 00:42:07,352
and write it as 2.

674
00:42:07,896 --> 00:42:09,400
Then what value would we get?

675
00:42:10,194 --> 00:42:12,493
Now, if we bring the 5 over to this side…

676
00:42:12,576 --> 00:42:16,212
[Ena] I went up to the rooftop
during the session because I felt stuffy.

677
00:42:17,256 --> 00:42:19,847
And if I'm remembering things correctly,

678
00:42:20,433 --> 00:42:22,564
nothing interesting happened
up until then.

It was almost flawlessly executed.

691
00:43:29,390 --> 00:43:31,813
They must have been nervous
since it was their first,

692
00:43:31,897 --> 00:43:35,491
but they didn't slip up like an amateur
or leave any traces on the scene.

693
00:43:36,745 --> 00:43:39,754
I suppose, the only failure
on the killer's part

694
00:43:40,423 --> 00:43:43,264
was that the puzzle piece
didn't get much attention.

695
00:43:45,980 --> 00:43:48,656
Had they put away the soju bottle
and sleeping pills,

696
00:43:48,739 --> 00:43:50,620
the case wouldn't have
been ruled a suicide.

It would have become

[♪ music fades]

700
00:44:07,879 --> 00:44:08,882
Who, me?

701
00:44:10,011 --> 00:44:12,686
Captain Yang asked you
whether I was the culprit?

702
00:44:14,442 --> 00:44:17,116
I wonder why he suspects me.

703
00:44:18,286 --> 00:44:20,752
Mok-dong Apartment unit 314.

704
00:44:23,719 --> 00:44:25,725
[breathes deeply]

705
00:44:25,808 --> 00:44:27,689
[tapping]

706
00:44:29,026 --> 00:44:31,618
What were you doing at the time
of Ganghyun's death?

707
00:44:31,701 --> 00:44:34,334
[breathes deeply]

708
00:44:35,002 --> 00:44:36,005
That night,

709
00:44:37,051 --> 00:44:38,680
I went up on the roof to chill.

710
00:44:38,764 --> 00:44:40,686
I really, really didn't want to study,

711
00:44:40,770 --> 00:44:43,236
and if I went home,
my uncle would've talked my ears off,

712
00:44:43,319 --> 00:44:45,576
so I went up to the roof to get away.

713
00:44:46,245 --> 00:44:47,331
[sighs]

714
00:44:47,999 --> 00:44:49,880
I thought you trusted me 100 percent.

715
00:44:51,260 --> 00:44:53,600
Why didn't you tell me
you knew Ganghyun Lee?

716
00:44:53,684 --> 00:44:56,484
He was your friend's dad,
how could you not have known him?

717
00:44:56,568 --> 00:44:58,949
You didn't tell me
about the handkerchief either.

718
00:44:59,032 --> 00:45:01,374
-Not true, I did tell you about that!
-Yeah, too late.

719
00:45:01,458 --> 00:45:03,337
That's because you never
pick up your phone!

720
00:45:05,553 --> 00:45:07,308
Look, I did tell you in the end, though,

721
00:45:07,392 --> 00:45:09,607
so why didn't you ever tell me
you knew Ganghyun?

722
00:45:10,317 --> 00:45:12,782
We all have our embarrassing secrets,
okay?

723
00:45:12,866 --> 00:45:16,042
Did I really need to tell you that
I got illegal tutoring in high school?

724
00:45:16,126 --> 00:45:18,508
If it was relevant to the case,
then of course you did.

725
00:45:20,138 --> 00:45:22,186
[sighs] Then how about Jungho?

726
00:45:22,269 --> 00:45:25,613
Why do you think he didn't say anything
when he knew about the Ganghyun case?

727
00:45:25,696 --> 00:45:28,580
When I first brought up the puzzle pieces,
why did he ignore me?

728
00:45:28,664 --> 00:45:31,631
Because he doesn't trust you.
Because he thinks you're the killer!

729
00:45:31,714 --> 00:45:35,057
I can see why he thinks that,
but why did he leave you in the dark too?

730
00:45:35,141 --> 00:45:38,109
He had a lot of time to tell you
everything that he knew.

731
00:45:39,488 --> 00:45:41,995
[Hansaem breathes deeply]

732
00:45:43,667 --> 00:45:44,795
[pounds on table]

733
00:45:44,878 --> 00:45:48,180
You need to decide
who exactly you're going to trust.

Cheoljin Oh

738
00:46:26,379 --> 00:46:28,468
[sighs] Cheoljin…

739
00:46:31,811 --> 00:46:33,650
Cheoljin…

740
00:46:34,778 --> 00:46:35,781
[door opens]

741
00:46:37,829 --> 00:46:40,546
Ena, I didn't know you were here.

742
00:46:42,217 --> 00:46:43,555
Youngim…

743
00:46:43,638 --> 00:46:46,020
do you know anyone named Cheoljin Oh?

744
00:46:46,103 --> 00:46:48,612
Who? Cheoljin Oh?

745
00:46:52,499 --> 00:46:53,877
The name's quite familiar,

746
00:46:53,960 --> 00:46:56,008
but I don't think
I've ever met him before.

747
00:47:11,346 --> 00:47:16,362
[♪ pensive music continues]

748
00:47:23,466 --> 00:47:27,184
Ena Yoon: Decide quickly whom to trust.
Once you do, trust me no matter what.

749
00:47:41,479 --> 00:47:43,149
[traveler] Look over here.

00:47:43,902 --> 00:47:45,908
-One, two…

[seagulls calling]

[sighs]

754
00:48:18,506 --> 00:48:21,474
Do you remember that you always
sent gifts to my uncle?

755
00:48:22,016 --> 00:48:24,775
You sent something on holidays
and my birthday.

756
00:48:25,276 --> 00:48:27,950
No wonder your name sounded familiar.

757
00:48:28,034 --> 00:48:29,288
[chuckles]

758
00:48:29,372 --> 00:48:30,793
I sent things on your birthday,

759
00:48:30,876 --> 00:48:33,802
'cause I heard
Superintendent Yoon loved his niece a lot.

760
00:48:34,888 --> 00:48:37,144
Besides, they weren't really gifts.

761
00:48:37,772 --> 00:48:39,694
They were more like telephone fees.

762
00:48:39,778 --> 00:48:43,706
There's a lot of things that can be solved
with a simple phone call.

763
00:48:47,216 --> 00:48:48,513
Wow… [sighs]

764
00:48:49,180 --> 00:48:50,811
That was a long time ago.

765
00:48:51,939 --> 00:48:54,447
Did you really come all this way
just for that?

766
00:48:55,156 --> 00:48:56,620
No, of course not.

767
00:48:58,710 --> 00:49:00,046
Did you know Ganghyun Lee?

768
00:49:03,766 --> 00:49:05,354
You did, didn't you?

769
00:49:15,008 --> 00:49:16,722
How do you know Ganghyun?

770
00:49:18,394 --> 00:49:20,609
Are you really Chief Yoon's niece?

771
00:49:24,118 --> 00:49:27,546
I don't think I should tell you over text.
Let's talk in person.

772
00:49:27,630 --> 00:49:31,139
What are you up to right now?

773
00:49:34,065 --> 00:49:35,151
[clicks tongue]

774
00:49:41,588 --> 00:49:44,012
Calling…
Ena Yoon

775
00:49:45,392 --> 00:49:50,574
[line ringing]

776
00:49:50,657 --> 00:49:51,994
Hey, hello.

777
00:49:52,077 --> 00:49:54,000
[male voice]
Hello, this is Ms. Yoon's phone.

778
00:49:56,383 --> 00:49:57,803
Hello?

779
00:49:59,642 --> 00:50:01,899
This is Ms. Yoon's phone, right?

780
00:50:01,982 --> 00:50:03,488
[male voice] Yes, it is.

781
00:50:03,571 --> 00:50:05,241
This is the Jeju Police Station.

782
00:50:05,325 --> 00:50:07,458
What's your relation to Ms. Yoon?

783
00:50:07,541 --> 00:50:10,801
Oh, I'm Lieutenant Yoon's colleague.
Did something happen to her?

784
00:50:10,884 --> 00:50:13,224
[male voice]
Uh, this is a bit hard to explain.

785
00:50:14,060 --> 00:50:17,655
Lieutenant Yoon is at the station with us
due to a delicate matter.

786
00:50:18,449 --> 00:50:20,622
Is she there to assist you on a case?

787
00:50:20,705 --> 00:50:21,834
No, she's not.

788
00:50:22,545 --> 00:50:24,215
Actually, she's a murder suspect.

789
00:50:25,595 --> 00:50:26,598
What?

790
00:50:26,682 --> 00:50:29,440

Excuse me!

Uh… What are you doing there?

794
00:51:01,034 --> 00:51:02,873
[dock manager] Hey, excuse me.

795
00:51:02,957 --> 00:51:04,671
What are you doing over there?
