I don't know one KPop group from another so when I watched this, it was simply for my enjoyment. In ways it reminded me of the short drama called Fight; however, there was not a group of people, just one. I like it! Maybe its the me who likes violence but it was a deep story. When the main character found himself so into the violence that he really could not stop, that's when it really got interesting. Definitely a different take on the causal effects of bullying!
