Ok after read the novel (i'm currently at vo1.1 ch.72) I can definitely see Inseop loved Wooyeon as an idol. His admiration since long ago was all about his appearance and he doesn't like the fact Wooyeon sexualize him. He was sad and depressed everytime Wooyeon sexualize him. Maybe I interpreted wrongly but that's how I see in Inseop. He just like a pure child. I was angry when Wooyeon r*ped inseop few times but inseop failed to see it as a crime. Either he's too dumb or too naive. It doesn't feel romance from inseop part. And from Wooyeon part it feel more like obsessive. Like he was straight before but become gay because of inseop. So it was new thing to him and he was too obsess with it. Idk maybe i was too stupid to understand their type of romance ┑( ̄Д  ̄)┍
