The more I read this, the more I realize that Woojung is not actually a good adult.
Apart from the major ick that he had sex with Jiho the very night he turned 18 (him being a prosecutor and all, you'd think he had a greater sense of moral and responsibility than this), he also never seeked any professional help for Jiho. Considering he literally picked Jiho up by the side of the road- a suicidal beaten up teenager, you'd think the first step he took is getting him psychological help. And then pushing him towards proper education and necessary stuff like that. Not start a romantic and physical relationship.
