One of the best things about this drama is acting. The cast is nothing short of perfection making the story a lot more memorable and impactful. I really cannot praise them enough. And, while everyone deserves an A+, I feel like the supporting cast outshine the leads only because the villains are much more dynamic than the main characters.

One thing I like about Part 2 is that the villains are written to be so fundamentally irredeemable, they become destructive and often self-sabotage. These so-called "friends" ultimately become each other's worst enemy making their individual endings very satisfying. The storytelling and pacing continue to be smooth without filler arcs and incoherent content. I like that writers did not concoct unnecessary plot devices to create more drama. Everything is very well balanced.

While, for the most part, the story is well written, the ending becomes too contrived with unnecessary twists blurring the lines between good and evil. The good guys become murderers and the villain become victims. But, we are still supposed to be sympathetic to the "good guys" because the villains deserved it. I guess the writers wanted to convey that the world is not fair and at the end even people who seemingly can do no wrong are capable of heinous acts. But to me it makes the good guys no different from the villains, which is very disappointing because I rather liked how the writers portrayed certain characters to be exemplary in contrast to monsters like Park Yeon Jin.

I did not love the ending because it felt like Joo Yeo Jung's revenge story was thrown together last minute. The plot reached its logical conclusion with Dongeun finally getting her revenge. I was ready for the drama to end only to be forced to watch Yeo Jung's revenge arc, which at that point wasn't that interesting. It is not because his story wasn't compelling, but because it was not properly developed early enough and was only written as a tiny side arc in comparison to Dongeun's grand revenge. The ending did not really feel like a happy ending where the main characters get their revenge and move on with their lives. Now that their roles switched and Dongeun became Yeo Jung's "executioner", they got stuck in an endless loop of revenge with the last scene showing them entering the prison with Yeo Jung father's murderer. It made me feel bad for the characters because they deserved better than this.
