Dude, it was not his fault that his parents ran away and he had to use his life as a collateral for the debt. The only condition they gave him was to live under the same roof with FMC, even if they are living together, the FMC's family have given him the right to do what he wants to do. He selling his life does not equate to him selling his cock. He ain't a sex slave. Let the man do what he wants.Bro this guy sucks. She takes away all your debt and gives you a place to stay, and you can't even go out with her?
Disregarding the fact that the feelings are mutual, the very least he should do is eat her fucking ass for doing him such a massive favor. But then he has the gall to call her shameless for wanting to have a relationship with him?
The most miniscule amount of power he was given because she confessed first has gone to his head and now he's delaying his response because he's a fucking spineless asshole who cares more about appearances than the woman he loves.
