I don't think so? I kinda remember him saying "I don't really care, but Hwagok would be sad, so I'll just pretend."
And at the end he still helped... is a different matter (here, at first he find Seolhyun annoying because Lee Bin's personality is that he thinks unrelated to him bothersome like that but he realized that Seolhyun gave Hwa something they failed/lack to give him and so he did what he can do to help)
In chapter 91, Yibin said he doesn’t care about his son?? AND THAT ITS BOTHERSOME?? So he doesn’t actually give a shit of what happens to his son? I am confusion
