The most violent answer to school violence!
A high school student, Seong-jin, was the victim of school violence for a long time. Three years later, one of his bullies, Han Yeo-wool, debuted as a celebrity. Seong-jin’s brother, Seong-hyeon, blamed himself for not recognizing the pain his brother went through and found a comment on Han Yeo-wool's news report that Seong-jin didn’t commit suicide but was instead killed by Yeo-wool.
Seong-hyeon set out to find the truth and he headed for destruction. (http://www.kan84.net/bdhd/btbaoliguize.html)...
