Honestly I don't even know what to say? I really hope all that mommy bs is just stuff being mistranslated (I'm in denial) but even then beside the mom kink can we talk about lil bro actions?
I think we brushed over the fact he tried to put a photo of teacher wearing a raunchy cow underwear being humiliated as his official picture of the university website. This is insane, not having a mom doesn't justify being a horrible person, he had his big bro as a role model (he may be dumb but he's kind and responsible towards him).
I have trouble really analyzing his character because of the translation but he's really getting creepier. Exchanging his name with his classmate to play a prank on the teacher is funny. Running his teacher's carrier isn't
