@HSahzad108277 it's probably hard to empathise with him because you haven't experienced the childhood he has. This guy was literally an accident, by that i mean his parents didn't mean to have him. Sure his parents still cared for him, but they didn't really love him like a parent should, that's why he's so mentally unstable because when you grow older shit happens, but unlike most people Punpun never had that support that he could count on, he had to figure out everything on his own, which resulted in his twisted way of thinking of things. He also didn't have any friends or try to make friends which resulted in his low self-esteem, he was raped by his aunty, couldn't keep his promise with Aiko, etc. That's why he's got such a weak personality.
