It's so satisfying to watch Yoon-ho be the cause of their downfall. That dude was a ticking time bomb. A true psychopath stabbing the innocent mill owner and bludgeoning Lee Myung-guk. When he followed Hyun-woo's grandmother into her house, I screamed bloody murder. I was scared for Woo-sung's life for photographing him.

While they're all irredeemable, I've felt sorry for each of them at least once.
-Tae-jin: They're his ideas, yet Jong-soo reaps the rewards, and the chairman will toss him aside.
-Jong-soo: He is never good enough for his father, so has to turn to drugs. I pitied him when he begged his vice president friend, "We have to show them this time."
-Chi-hyun: He's loyal to Jong-soo, yet when he slapped him, it proves that he's no more than a lowly servant. I admire his calm, cool, and collected personality.
-Sang-eui: He's my "favorite" and genuinely seems to care about Joon-seo.

But never Yoon-ho. And now same with his wife Si-jung shifting the blame to Jae-kyung. I only feel sorry for their daughters for having a murderer as a father.

I read a theory about Joo-song being the Doctor, which could be possible. I adore Joo-song's character, but I just think it'll be too easy if Noh Gyu-min is the Doctor. How can he be the Doctor and Joon-seo's taxi driver and none of them remembers him from high school? Presuming Gyu-min escaped from the fire, he must be under intense guilt watching Kyung-tae burn to death.

I hope "0305" has a different meaning, otherwise Joon-seo deserved to be cheated on. Nevertheless, it's not the passcode, and now Tae-jin has one chance left. Boo, I was rooting for Chang-soo to be good. Good as in a dirty cop who accepts bribes but not kill people. Is it wrong if I still like Jin-wook? It was self-defense, but I did gasp when he didn't even hesitate when he shot CEO Yoon. Many thanks for the recap, @solstices!

Would it be too obvious (at least to the viewers) if the password was 1882? Then Jun-seo's question as to whether JJK still remembers it might have a completely different meaning than previously assumed.

Because of all the people involved, I sometimes have trouble telling all the names apart. And I had definitely forgotten that the body of the murdered researcher must have been frozen for a while. So it was a surprising revelation to me what role the frozen warehouse played.

After Chang-soo's fabricated accident, it's pretty certain that he will end up dead. The writers probably won't send him to prison.

As always, the scenes with the three friends provide a bit of laughter. It really was a memorable birthday party.
And I had to laugh that a drug-addicted JJK still has more stamina than Joo-song.

Doesn't Ji-sung look adorable in a white T-shirt?

I don't know if it is just me. But the show got improving in the second half despite having a bit shaking start. The last 4 episodes had me hooked and I keep craving more. Perhaps, I will binge this after it concludes its run as a rewatch to revel more in its twists.

Yoon Jin and Chang-woo. Sigh.

Chang-soo, oh no!!! It probably would have been simpler to come clean with Jae Kyung. When he steered the car I knew he won’t get away with it. lol. He should have known too, after all he worked with Jae Kyung.
Finally, Jae Kyung found where he was drugged. But lost both the parties who were involved.

Time and again Jae Kyung told her Tae-Jin is too dangerous. She is lucky to have a friend like Joo Song.

Chairman is an awful person but he sees right through Tae Jin. What an audacity that man has. ‘Work hard to make us rich but dare not expect anything in return’

Is Tae Jin the doctor?? Who gets the most out of drugging JK? If it was Tae Jin he would have tipped off the cops to get him off the case. Did someone drug him to get him close to the secret or away? I think it’s the former. I can’t read Sang Hui. He really is not part of the friends group but he knows more.

Ji Sung runs so beautifully. Every time he runs his whole body is acting. I can watch him all day. 😍

Of all the things I was prepared for, I was not prepared for Kwon Yul(Tae-gon) going ballistic on Yoon-jin. Kwon Yul was irrecognizable in that scene.

Shameless is an ugly word that packs a punch. When Ji-Yeon calls Yoon-Jin shameless for pushing to get her husband’s insurance money when they were not close friends, Yoon-Jin holds her tongue about JiSeo-Yoon’s affair. But the clever writing of the birthday cake suddenly makes Ji-Yeon sick: the passcode is Ji-Yeon’s birthday. Ji-Yoon gets sick because she realizes her husband was still in love with his college girlfriend . . . or worse, had an affair with her. Tae-Jin was shamed by CEO Won who already knew Tae-Jin’s grand development plan contained embezzlement portals to make Jong-Soo and himself rich. CEO Won told Tae-Jin he had crossed the line; he was not as smart as his plan was supposed to be. He was exposed, uncovered and easily replaceable. Tae-Jin’s one chance of getting rich is collapsing because of his dumb rich friend and the incompetence of his classmates. But now his own incompetence was laid bare,

We also learn that Joon-Seo knew of Ji-Yeon’s affair. He called the KH gang to the construction site to expose all their secrets. Apparently, he was in the drug business in order to get $500,000 for his daughter’s medical care, but when that did not work, he let her go. His last quest was to put things right. Tae-Jin, Jong Soo and Chi-Hyun all claim to have not killed Joon-Seo, but the wild card Yoon-Ho killed the rice mill owner to cover his own tracks, tracks that lead directly to the other three. Chi-Hyun admitting he killed the chief researcher and froze his body, but claimed he did not move it to his house to be found. That was done by CEO Yoon’s goons, the same guys who drugged Jae-Kyeong to get him to investigate and eliminate her competitor, KH gang, like she did with Jang’s Five Spider gang.

The flashback to Kyung-Tae’s hideout with Joon-Seo spilling petro for the stove is the precursor for the fire that killed Kyung Tae as Jong-Soo’s gang comes to rough him up. It is harder to imagine that Jae-Kyeong’s teen pressure for his classmates to rat out villains was the main reason for Joon-Seo’s last guilt gambit against this high school “friends” for Kyung-Tae’s death. It is more likely that Jong-Soo’s gang’s adult pressures and crimes drove Joon-Seo to sacrifice himself for the Truth as he had nothing further to live for (his wife was having an affair, his child had died, and he was caught up dealing illegal drugs.)

Ji-Yeon telling Jae-Kyeong, Yoon-Jin and Joo-Song the address where “they all should go” to find an old insurance policy clue sounds like a huge set up after she met with Tae-Jin. Would Tae-Jin be so cornered that he would eliminate four people just to get access to the crypto bank account and cover the bloodshed that leads to him? Perhaps.

Episode 10 is the set up for shocking secrets to be unveiled to the authorities. To thug the heartstring, Yoon-Jin’s daughter calls to wish her mom a happy birthday. But it is a day late because “she forgot.” This is the desperation point for Yoon-Jin to score a large...

I'm really glad Jong Soo had his moment to shine. He's not just a goofy guy there for comic relief. It hit home that he is the most decent core of the trio. He could be the one to try to steer the others from crossing the line. 

With crime shows, I'm conditioned to be wary of the innocent ones in case the writers want to give a big twist/betrayal. I truly hope he remains a good guy. We have plenty of morally corrupt characters. 😂

I wonder how strong is his crush on Yoon Jin. Three? guys liked her! in high school = Joon Seo, Jong Soo, and Jae Kyung?? There's still a mystery behind the reason for Yoon Jin & Joon Seo's break-up back then and their friendship with Jae Kyung during this time.

Dang, Yoon Jin!! I knew she wasn't a saint, but I didn't know how far she would go. Her desperation and greed for that money lead to immediate consequences. Thank goodness Jong Soo were there. I hope she had at least confided in him and planned for him to be her back-up. I hope she learned her lesson.

Initially, I assumed that the villain trio all had the same reason for meeting Joon Seo that night. All shared a dark secret from their high school which is actually true. However, they had other shady, personal reasons to meet him.

Never expect a funny scene like the birthday cake one - which is not just comedic but also pivotal in some major development. Got to give a thumb up to the writer for the interplay of an ice cream cake, the hiding, secret phone call and listening. We’ve seen so many ‘convenient’ hearings in dramas but this one, I approve.

The good old ‘know your own place’ is so well played out in the scene between the Chairman and Tae-jin. I had some sympathy for Tae-jin in this scene after all these years as the ‘brain’ of the group. Food chain never changes unfortunately.

I’m sure Yoo-jin will be OK after the internet bar incident and hopefully learn a lesson. Now that we are going into the final stretch, I really want to know what’s the real cause for the fallout between JK and JS. It has to be a real big deal beyond effecting a school transfer for JK. The reveal of the backstory is locking step with the main story development and this really keeps me on the edge.

More than ever, I am convinced:
* the passcode is the SOS one between JS and JK (1881?)
* JS was the one planning the whole thing for JK and JS to be involved so as to reveal the deeds behind the group / doctor / drugs / stash fund
* Chang-woo did not involve in drugging JK but knew about it.

Finally, the last time I watched Ji Sung was Secret Love. So pleased to see how great an actor he is now - so very good.

Honestly, we got more character development for our "good guys" this week than our villain gang and I think that says a lot. It's interesting to have Yoonjin be a shamelessly "immoral" person — our intro scene to her is her accepting bribes and here she is again, tailing a cheating couple for money she doesn't know anything about...all for the sole custody of her daughter. It's unsurprising and yet, disappointing. Same with Changsoo, it was suspicious that he was covering for Jaegyung so needlessly loyal, yet it turns out, he has his own fair share of secrets to cover for. It's disappointing because I wanted to root for Jaegyung to have someone trustworthy on his side, but they're all flawed (except for Joosong who I'm still holding out hope for). But I love the questions brought up about how much Junseo planned this cat-and-mouse game, what happened 20 years ago, and who's still calling the shots now.

I'm so curious about who is the outside instigator. On the one hand, setting up Jae-kyung and Yun Jin through the texts in a way that would get them to investigate seems like someone who wants the truth to come out. At the same time, drugging Jae-kyung is much more sinister.
I don't think it's one of the four main baddies as in their meetings they are all so paranoid. Tae Jin seems like the only one really smart enough to pull it off, but it set so many discoveries going that TJ freaks out about that I'm not too certain.
I wouldn't be suprised if it's Joo Song. He showed he is smarter than he lets on this week. I think he's totally capable of sending the texts, although the drugging seems unlike him. Yet, I could see him harboring some jealousy for Jae-kyung, which would be more than he's showing on the surface. This week, this is my bet.
I also could see the high school friend who told Jae-kyung everyone was there to see the suicide. He seems an unestimated sidekick.
The other possibility is that Jun Seo set it all up before he died, to send out the texts and get Jae-kyung drugged. Both would be in character for her, as he feels remorse but has done a lot of shady things.

With Chang Soo now gone even deeper to the dark side, it seems less likely that Jae-kyung can come out convincing anyone that he was innocent in getting addicted to drugs. He could easily say his motive was to hide what happened to his hyung. I feel really bad for their very cool female superior. She's going to take a big hit once it is all discovered.

The show is leaning towards Tae Jin as the main culprit behind Joon Seo's murder. There are people on both sides (Yoon Ho and Jae Kyung, Yoon Jin) that has brought up his name more than the others. He seems to be the most cold and cunning. He has the motive, but so do others. I feel like it's gonna be someone else.

Random note: Kim Kyung Nam really sold Jong Soo's immaturity when he angrily kicked at the furniture and stumbled after.

I wonder if Chae Kyung survived and what happened to Gyu Min. Won Soo, Tae Jin, Chi Hyung and Yoon Ho will need to keep that under wraps
Yoon Jin has to keep Ji Yeon in her place for
calling her shameless. Ji Yeon deserve nothing from Jun Seo since she continues to cheat with Tae Jin.
Also thank goodness Jong Soo is devoted to Yoon Jin. Otherwise Tae Jin couldve killed her. Is it just me or I was happy to see Tae Jin body slammed on the table. I do not feel an ounce of pity for him.

The police would undoubtedly have conducted an autopsy on Boss Yoon. A ballistics test on the bullet that killed her would have revealed that she was shot with Jae-kyung‘s gun (which I find hard to believe hasn’t yet been discovered by the police to be missing, even if his superior has been covering for him). I was disappointed that the writers either missed this point or chose to ignore it.
