The drama doesn't focus on the school violence but rather on the love triangles among the students. A lot of things don't make sense and they didn't depict the resolution well. I still don't get why Kang Ha fell in love with Jae-i, especially why he would go to such lengths for her. The more I try to wrap my head around what happened, the less I understand the point of the drama... Sad to say what a disappointment it was after watching the trailer.
