totally! he probably thinks that Wolfgang is just like the old king. since he’s his son he assumes he’s been raised the same and is a terrible person.
and red hair dude, the nice one that likes shin(sorry it’s been a while i’ve forgotten everyone’s names) probably knew shin was one of the kings children, and then he sees wolfgang taking shin, so he probably thinks shin is being forced to be w/ another king when he’s not, but he doesn’t know that, he just thinks “like father like son”. which isn’t necessarily wrong for the first three sons since they were raised as royalty.
but anyway, he doesn’t know wolfgang like we do, and i think it’s sad bc he genuinely likes shin and wants to help but at the same time shin doesn’t need any help and doesn’t care about him at all :/
I kinda feel sorry for the red head. I don't think he's a bad person, he's the type of antagonist who really thinks he does something "good" because no one taught him the diffence between right and wrong - or how to deal with love and empathy. He's actually also a victime and manipulated.
