I don't remember the events, but the side story in the novel is a bit different from the one in the manhwa. I remember almost not reading the side story because the ML became sort of a dick. I have to reread it now. I believe the ML was the one who kept his distance and didn't want to introduce the MC to his family. There was also the conflict surrounding their inability to have pups. I think the ML was being pressured by the people around him to have pups, and he was being an a-hole to the MC because of it.
