I agree but I don't think Kai is like that, I think it's him like being a little brother and not wanting to see his older sister get married, I think he'd be the same way if it was any guy
I thought that she got away just to fuck and he "let them" marry because she got pregnant, wasn't he trying to kill him when he surprised them in the middle of the act? Wasn't that what she said to the FL?
I hate when the brothers can act like male prostitutes but they go and fuck up all, when their sisters are enjoying (ノಠ益ಠ)ノ彡┻━┻ that's not a "cute" way of being a brother
