She's the thot from the first chapter. The sadist that enjoys watching him suffer. She probably wants to become his gf to cuck him and watch him suffer more. @kefkabot
I can’t really dislike her like others do, cant see her as thot... sure she’s said she’d love to “bully him to death” but i don’t see it that different from Takagi-san or nagatoro. She did call him a cutie and that he was her fated one. So yeah I ship it 😤
