Bet that girl has a crush on Ageha. This is why you don't jump to conclusion or to any other people's business that isn't your own until you get a clear understanding because some might just think you're an insufferable piece of shit and you'll only make the visible problem worse than it already is. BUT i can get where she's going at.
Peolle calling it grooming when it's practically the kid seme leading the relationship :/
