Ongoing 타임즈 업

[May I ask what your school days were like?]
[There was nothing particularly problematic.]
Choi Yun-ho, the perpetrator of terrible school violence. His blatant lie announces the beginning of it all. Twin brothers, Lee Jin and Lee Joon, who were victims of bullying by him. The two try to personally condemn Choi Yun-ho, who was the perpetrator.
[I hope you don't give up in the middle.]
It's time for the roles of perpetrator more.. and victim to reverse from now on. What is each person's feelings in all the actions done in the name of revenge?
