he went with his ex, to get a nude photo soo that he couldnt threaten min woo anymore. . . are we reading the same yaoi? also he clearly was fantasizing that min woo was better, and then said that the thought of min woo got him horny, he never said anything like that about his ex, in fact he showed open hate for the ex, he never had any relations with anyone else after he started seeing min woo, even before they made it official
LOL read the manhwa again. He did NOT go there to get nude photos of his ex, he went there to have sex with him. He literally said it himself and thought that 'Even after they slept together, his ex still wouldn’t stop.' He only started thinking about the nude photos after he talked shit to Minwoo. Also, he literally blushed when he saw his ex’s body and even thought his body looked good even before like why would he suddenly think of that? It’s so unnecessary

just say you still wanna fuck w ur ex you dumbass bitch. mc like this who treat their partners like shit is so fucking annoying. idfc if he only did that for minwoo, that bitch still fantasize his ex and tried to have sex with him while still in rs with minwoo. fucking nerdass loose bitch fucking ruined my whole day and its only the morning
