So I just wanna mention that we don't know about that woman. Imagine being the man in love with his childhood friend but still giving your best in your marriage and in raising your child and then your girl cheats on you :0
I think there's a reason to why the child is with the man and why she cheated. Maybe she also loved someone else or were forced to marry? Maybe it was an omiai or something similar.
You assume the wife was some high class pure girl but she doesn't have to be since the author decides that and also there are lots of wives in real life that have it worse.
Imagine you fell inlove with this kind of guy as a woman. He's actually gay? That's true horror. Plus he's got your kid. If he wanted a kid so much then he could've just payed someone to fuck and have his baby. The girl cheated? Yes . He knows it well. The girl probably knew he's not straight or he's got some probs going on. Good choice. I wouldn't want to see a yaoi where they twist the story to get their "happy ending" while the woman doesn't know whats going on and get cheated with to dudes
