It's not that he isn't able to fight ... he just doesn't want to cause trouble for taesung and his mother ... so in order to avoid getting hit he obeys those bullies
I like his character the way it is actually ... he really is kind and wants to repay them for taking care of him since he was a little boy
This is just my view of things ╮( ̄▽ ̄)╭
I understand what you mean but has a person who dosent take shit from anyone I want to help but can't because its a Manhwa ╮( ̄▽ ̄)╭. it makes me cringe like in real life because in school i stood up for a lot of people in this situation including teachers. So I can't help but want everyone to become stronger. Also I feel the mother would understand and his step brother or what ever(forgot his name) would also tell her what happened to. But i Know its just his character but it really just makes me cringe.

There is a limit to how much i can feel bad for the MC and its past that. Like i was mad at the bully but now i just get mad at the MC because he continues to let this shit happen. I thought he would learn to be smarter but i guess not.
