He allows his pregnant girlfriend to work in a brothel, justifying it by saying that he lost his arm(He says he can't work, but at least his girlfriend supports him.).Then he loses his child because of this, and it seems he will improve...but this is gilk. He was in the web novel too often, giving the impression that he would become more normal... but after 2-3 chapters of his side story, he became even worse. I just don't believe him.
