Choi Hyun Wook is the standout here. He is such a great actor that he steals every scene he is in. The story itself is about bullying in a high school and how a ragtag group of students band together to defend themselves. I wish that the bullies had been portrayed with as much nuance and moral ambiguity as the "weak heroes," instead of just being your typical bad guys. It would have made for a more interesting drama. But this is still pretty good, primarily due to the stellar acting by the young actors.
