Should have also thrown the glass cup at him : ), would’ve been ever more satisfying, like who the fuck are you to interfere into their „relationship” that you barely know anything about and didn’t he said himself that it was „after graduation promise”? The thing that she’s doing right now to Arase is supporting him and giving hugs some times which is not illegal because many kids are guving hugs to their favourite teachers in kindergarten for example or something like that. So I don’t find it illegal or anything like that, also I know a girl that git into a relationship with her highschool teacher after graduation and then married him.
