Seriously? Painter of night has a master and slave story so the "extreme" abuse you're idealising atleast makes sense. Kiss me liar is a omega verse which i don't read so idk. And as far as i remember bj alex has no physical or verbal abuse(other than that one time alex accuse uke for being a stalker which he kinda was), sa or ra** in it. It just has bdsm or s** partners relationships. IM NOT SAYING WHATEVER THEY DID WAS RIGHT, JUST SAYING THE CHARACTER'S BEHAVIOUR WAS EASY TO UNDERSTAND for us readers.
But the dude right here is literally a freeloader, rude and violent for no reason, homophobic and pis*** on his brothers sexuality and s** life when hes literally a fuckboy. His action just doesn't make any sense at all. He is immature, abusive and violent just towards uke unlike other semes who were abusive and rude everyone in general.
