This is genuinely one of the best k drama´s i have watched, i reality a lot to the victim. Because i have been a victim of bullying myself and i would love to take revenge on them, but i would never take that type of revenge like the victim did obviously cause i would have been in jail lol. The acting is amazing the plots are mindblowing. This is a drama, you just want more of and just want to continue watching, It is also realistic you can really see and understand the victims point of view. It also didnt have a disappointing ending. Please watch it, it is totally worth it and im so glad i found out. You should definitely watch it too. It does contain a lot of blood so don´t watch it if you are senstive to that. This is a k drama i will never forget fr.
