I'm a fan for childhood friends but this one deserves to lose, after put him in the friendzone now you pull this with the kiss... mots of the time is the guy who gets ntr'd but this girl deserves it.
It's easy to say that is a joke but even when you say it it hurts, no wonder the mc is like that with a mother like her, she wanted a girl and then she tells the girlfriend that he's a loser, she doesn't even trust her own son with a girl, damn...
