Just finished watching and I have to say, this was very well written. Amazing acting with perfect ending. I don’t think this series was very populair but to me it deserves world wide recognition.

I often predict what can happen next in almost every K drama, but this show gave me unexpected revelations with every episode. The satisfaction after completing the series is unexplainable… wow.
Much appreciation for the team that worked hard to fulfill this. Strongly recommended!

The flashback scenes about bullying in school gave me chills, it was rough to watch but panoramic and comprehensive. It showed everyone in everyone’s perspective. When you watch this you can’t help but long for payback and righteousness, and feel sympathy and understanding for why one of the friends is doing what he is doing(revenge).

The perspectives subtly change from scene to scene until in the end of the series your whole perception of what you though was going on shifted. In the beginning you have two main characters, the one a cop the other a serial killer. You come to think you understand clearly who the bad and the good guy is but after several episodes you will see it is not that simple.

The acting was perfect, the actors did not need to say much, it was shown. The word “ crazy” came on in itself. Kim Dong-wook acts with his eyes. When I watched him I was almost out of breath. I liked the series because it felt so dark and distinctive, but deep and compendious.

I also feel like this show is criminally underrated and do not understand why?
This show is absolutely a thrill.
The ending was such a masterpiece, I cried a lot. One of the best I have ever watched this year. I was so impressed with the ending, it was by far the most touching feeling.
Kim Cheol (Choi Hyun Jin) carried the show. The scene where he stands up for jung jong-suk and hwang kyung-min is brilliant. When Cheol was fighting he looked so cool. Much commendation to the child actor who played him. Cheols roof fight, I was moved by his determination to win and how he would not give up for his friends.

The character Cheoli inspired me so much, as a christian he had likeness to Christ, but ofcourse he is not. It seemed symbolic to how in the christian faith, Jesus was willing to sacrifice himself and fight for us when we fail to overcome the trouble that comes in our way.
But at the same time He also motivates us to stand up ourselves and follow in His footsteps for righteousness and victory. Now Cheol’s character is a human student who cannot save anyone, but this was the symbolism that I recognized. It was beautiful.

Overall, this show is a masterpiece. It shows the frightful effects of severe bullying and class discrimination. And how it can make a child feel hopeless and give up. You always have a choice to stand up for righteousness or to just stand by and do nothing about it, or even accept it and join in. It made me reflect to my own life and the bullying in my past. It shows that victims can bear the emotional scars for a lifetime and the psychological effects are so severe, that it could drive a person to insanity and hallucinations. It is a clear warning sign what carelessness can do for the future. Where some lose hope and give up, others keep on fighting and go forward to what they want to do and want to become.
