idk what the real reason is that yohan is hated by his family BUT if i had to guess id say he was probably caught with another boy / they realized he has an attraction to men and thats why they shun him (them being heavily christian / rich and worried about reputation / being conservative probably attributes to their homophobia) that would make the most sense considering the dad asks the MC if yohan has “done anything inappropriate” to him, and also why he laughs after the MC says he’ll “set him straight” (cause he’s gay??)

Worst case scenario is that Yohan molested someone, but i’m thinking it’ll be something like he got caught kissing another boy and the other boy places the blame on yohan maybe to save face with their own family and try to look like the victim. But who knows lol, these authors like to throw curve balls when you least expect it!
so..
this yohan actually a troublemaker... or its just his dad is a jerk?
i dont mind if anyone can spoil the rest (=・ω・=)
