First of all, if you think this drama is about bullying, it's not, well the focus is not on that. The focus is uncovering the incident on how & why Sun Ho had a near death experience when he fell off the school's rooftop. That led to his parents investigating and finding their own clues when the police couldn't do much due to lack of evidence and law regulation they must followed. The only part where school violence actually comes in is when video of the boys playing "the avengers game", pretty much beating up 1 guy or in this case Sun Ho. Otherwise, it's more of a personal investigation which leads to many events unfolding, all connecting to each other.

Story: It was an interesting plot but somewhat predictable that the one with the most power ends up being the root cause of it all. Nonetheless, I enjoyed it but could've been handled a bit better in my opinion. The ending felt very rushed. Too many things happened in that last episode. Instead a lot of it should've been spread out to previous episodes. Same goes for Sun Ho's awakening. That took way too long too. If he would've woke up a lot earlier, I think the plot would've progressed smoother. That would've let more time with Sun Ho's interaction with other characters and give him more lines since most of his lines were only in flashbacks. He was in bed for most of the drama. I wasn't too fond of that, knowing he's a really good young actor.

Acting/Cast: All of the cast did a good job but only two of the cast members shined for me in this drama. Cho Yeo-Jeong did a great job as Eun Joo. She convey her role really well from being a person that shows that nothing is wrong to a panicking & frantic person. It's very believable. Seo Dong-Hyun also done a great job at showing his evil side of his character and the vulnerability side of Joon Seok. I went from hating the guy to feeling sorry for the dude. I'm usually impressed with Nam Da-Reum's roles but it was limited in this drama so I'm kinda disappointed by that.

Music: The osts are on point. Loved every soundtrack and they all fit very well. From Haeun, Hanbin - Over the moon to Tiger JK & Bizzy - A Beautiful Lie, I loved hearing it everytime it was played whether it was in the drama itself or at the end of episode when they're showing a preview for the next episode.

Rewatch: It's too emotional for me to rewatch as a whole but certain scenes and episodes I may come back to just because it was performed very well.
