She was right, she fucks with anyone she wants, the boy want to be a good "doujin protagonist" but it is just a douchbag. They had a good friendship relation and mess with everything when he blackmail her, he is a son of a bitch. -"ah but he is a good guy, he would have treat her better" -dude, who are u to decide who a girl has to be with? if she have problems and like the other guys, to another.

It's kind of NTR adjacent. The point of NTR that sets it apart from typical cheating is the emotional torture and humiliation and there's a lot of that here. However it also subverts the typical dynamics: While the MC is in love with her, the girl doesn't care one iota about him, is genuinely in love with the sempai banging her and just has a rotten sadistic personality.

Everyone is a piece of shit in this story. The self-loathing girl, the guy that treats her like shit and fucks her and the guy who thought she was cute and quiet. Dude should get them in trouble as revenge. This feels more like a depressing indie film with its ending. Who cares if she hates you for the rest of her life when you got your ass beat that bad?
