He likes the MC, that's why he gets more pissed off when the MC is going off about how he'll please the other rapist/get along with his other friends thinking it's what he wants. But the main thing pushing this plot forward is everybody just having no communication skills. So the MC thinks that the ML wants him to act like a doll and please his friends (tbf its because how he pushed the third friend to have sex with the MC/how he calls him a slut and keeps going on about pleasing men) And the ML is getting violent and punishing him for sleeping with other men/"seducing" other men because he want the MC for himself but will never say that, he just expects the MC to fall in line since he conditioned him that way not understanding that the MC has no clue thats what he wants
Who's Heesung? Is he doing this because MC looks like him? I've only just read a few chapters from the middle, I'm waiting for it to complete
