Hobin getting manipulated because why would a guy getting builled go to the same school as the bullys and hobin. Even if his dad died, why wouldn't he train for revenge it's honestly normal or for them to fall into depression which has a low chance since he knows who killed his dad. So I think Lee jin ho is manipulating that wimpy guy.
@Sing Mang you do realize that not every bully victim is like yoo hobin, right? + jinwoo is way too powerful he cant just go and fight him, he cant buy a gun, and he needs like a year of immense training and its not easy to just get up and start learning and he's already scared of his bullies so what makes you think that he's not gonna be scared of getting blood on his hands or fighting jinwoo or wtv his name is
