I don't read this much either, but let's be honest.. him and the father won't work what so ever.. he is just insulting him, wants him to get married, trying to get him with women and making him a maid and so on. I also wanted him to be with the father but maybe if he changes in the future. Other than that, I think he has a good chance with the son again.
I see what your getting at and I agree but also let's not forget the son literally got with him to piss of his father and got a woman to piss him off again.. I wouldn't get together with someone who wants to use me to get back at someone.
I dropped this when he started doing the ex... Because I really thought it was going to be a him and the father... Because that's why I read it but then he started doing the ex I just.. Idk I felt bad... Because I like MC x older MC.. Idk.. But looking at the comments I'm glad I don't read this anymore.
