My niece's class girls are always clingy to him, and my nephew also thinks they are interested in him. When a boy harasses a girl, the girl asks my nephew to stand up for her.

My nephew feels it's time to show himself, so he took someone and beat her up. Her father is a boss and wouldn't back down, refusing to accept compensation, insisting on expelling my nephew. The girl disappeared completely, claiming she never asked my nephew to teach her a lesson, that it was him who insisted on stepping in.
Even after this, he hasn't learned his lesson and went to fight for another girl, beating up some troublemakers in society.
The girl is in cahoots with the troublemakers and doesn't even speak up for him. My brother still brags everywhere, saying my nephew is a heartthrob, that girls chase him, and most girls in the school like him.
In reality, he just likes to fight for girls, and people are just using him.
