The uke ressurects 3 men using body parts of his dead lover and someone puts the "insane seme" tag? Really?
Seems to me that the author is trying to make us turn against Guwon to whip out some plot twist (misunderstanding) later. If that's the case, I'm gonna be disapointed, because it's an move. Better make him an anti-hero kinda man from the start than to make excuses.
Now Gyeongha in the storage came to mind. Maybe she stole something?
