I wanna beat the crap of that glasses bully!
Like the dude has really no shame! After he got rekt so bad, he still trying to annoy the MC like he wants to be beaten again! I guess he's a masochistic pervert then.
Yeah, bruh, tell her that your mom found the letter, wigged out and dragged you to the depths of insanity. If she wants to help pull you out of those depths, she's a keeper.
