I've read the raws for 8th extra Chapter and guys, congratulations to us because HE DID NOT DO IT.
Explanation:
The 8th extra chapter will trick you in the beginning that he was taking advantage of Doyun/Doyoon because it's gonna show panels of him doing things to the poor sleeping guy. BUT THEN, he snaps put of his daydreaming.
Basically, he was at the heat of the moment imagining it. But ONLY imagining it.
His gold digger boyfriend (sort of boyfriend) HAS GOT TO GO. Mf will become an even more problem than the serial killer given that everything can happen in a manhwa plot.
