Did you even read the latest chapter properly? Bum was the one who wanted to suck him off. We dont know if SW is a rapist as of yet but to be honest it would be no surprise. Bum didnt suck him because he thought SW had just fucked his friend. Jesus christ people scrutinise everything from one panel. Either grow a pair or dont read.
Did y’all read too many stereotypical yaoi manga that it got “normal” and totally fine for you that “no” actually means “yes”, and it’s always ok if the ~seme~ forces himself on the ~uke~? And before you come at me with “but Bum didn’t even say no”, his body language was pretty clear and the reason why he refused to suck Sangwoo doesn’t matter or makes the act more consensual.
