Also Yeah. The truth is we don't really know why they fully target him. Possibly it’s because they finds his emotive expressions sexually exciting or theywants to punish him for his disregard of their feelings.
Regardless, these answers are not satisfactory. Why does they get off on watching his misery, in particular? We don't know. He is apparently mindblowingly attractive to women, so it might just be superficial. And furthermore, why is it his fault for not requiting every girl who likes him? He was trying to fulfill a duty to take care of his family after his mother died and he simply didn't have time to date. That's the easiest, kindest way to reject a girl. Yet, they demonize him for doing it, all the same. That's not reasonable, and thus, that explanation is also unsatisfactory.
So, there's more at work here, but we don't know yet.
