Yes, but u see it'll be different now because even if they do it or not they are gonna end up together, because hes the one that will make Leon change for the better (atleast i think so he has that type of personality). If they do it the guy will probably want to take responsibility ,or start dating him, not want him to do it with others, want leon to treasure himself uknow things like that. If they don't do it i dont really know whats gonna happen probably Leon will be impressed by him feel hes different or something or hes gonna feel worst about himself cause hes gonna think nobody wants him. things like that. This is Yaoi okay, and its not gonna follow things that are the 'norm'. Just know they will most likely end up together. We all know that there is always a fucked up character that will be saved by some really nice guy.
Leon can go fuck himself Idgaf about him. Even if he's just insecure and shit, I don't care, that's still no excuse for what he's done and continues to do.
