If you mean Sunhwa is mostly cause he truly did not like Sanjo he just wanted the idealized version of Sanjo he created, he wanted to mold him to his tastes cause if he had liked Sanjo for who he was none of this would have happened so I guess a lot of people are taking it from that. I also think that Sunhwa showed he really didnt like Nanjo by seeing Mok but icing out Nanjo. Which tbh is the reason I don’t dislike Sunhwa cause im sure if Mok had been honest to at least Sunhwa then he wouldn’t have felt as betrayed. Sunhwa implied that wasnt the first time Mok hooked up with someone that was inside him so its understandable he is mad
Btw just adding, cause i agree all of them are wrong… sadly even Nanjo

Come on, the uke's reaction is completely suitable for the situation. Why is everyone throwing shade at him on social media? He's one of the few ukes who has the guts and the backbone to stand up for himself.
