Bullying is not cool or funny, neither are the bullies themselves. Only cowards do such thing. Though some people don't do anything since it does not directly affect them. Like Yeong-Ho Lim(Yuna) who did not really bat an eye to the bullies or the victims. Sure he made comments to them, telling them it is not cool or how bullying was a waste of time.
