He did though. I mean, even just skipping over the first 4 or so chapters, the Boss still took advantage of Sooyoung (the MC) later.
If I remember correctly, the MC was being held accountable for his dad's debt to the Boss and his gang, so the Boss heat him up then gave him the ultimatum of either working for him as a part of the gang, or selling his body. He joined the gang, things didn't exactly work out with some of the other members, MC got into a violent fight with his abusive boyfriend, some other stuff happened, and the MC got fed up with everything and said that he'd just settle his debts with the Boss by giving him his body.
They did sexy things, but when the Boss started to take it too far, Sooyoung said no and told him to stop. The Boss's reply was "I know you don't really mean that. Don't you want to settle your debts as quickly as possible?" Somewhere around chapter 11/12?
Isn't that extortion or blackmail or something? Not a proper form of consent to begin with, definitely.
YUCK, THIS YALL MAN? Anyway, STAN THE GANG LEADER THAT NEVER TOOK ADVANTAGE OF THE MC
