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.
Get your shit together and get Jiho a therapist wtf are you doing like?? Do you not see his mental state? He's getting absolutely no help from you
THIS IS WHAT I HAVE BEEN PREACHING. like THANK YOU prosecutor thank you for taking him in you did a good thing but you are not the right person to help him get over his trauma!!
