Next chapter better have some explanation cause 11 chapters of having me hanging onto just Yaoi World 'abduction and rape' is not enough anymore. I need more. That Uke is a fighter but he also an asshole he probably had done something shitty in the part with that kind of personality I wont be surprised.

chapter 15-17 in that range.... too lazy to look at the exact one but i think it is 16....

It is so good that I went looking for the novel. For those who want it, I found it on wattpad from where Chapter 5.2 stops.

Is sungwoo in love with bum in a weird way?

In my opinion, no he doesn't love him. Not even in a twisted way. I think he sees Bum as prey and smut (snuff) material. In my eyes, Sungwoo is a type of person who loves to play fucked up psychological games (hence him making Bum kill that other guy and possibly kill this recent girl). If you look up the word "sociopath" in the dictionary, his face would be right there.

i think sangwoo does have a twisted romantic feeling towards bum. when sangwoo thought bum disappeared (and that time when bum opened the door), he wasnt angry because his victim escaped. he was mad because bum said he loves sangwoo, because he has been submissive so far, bec sangwoo felt betrayed. sangwoo actually blushed when bum gave him a handjob for the first time, remember? although i believe that sangwoo loves bum, (as someone mentioned below), it's probably an unhealthy obsession.
so to answer your question, yes, i think sungwoo is in love with bum in a weird way.
This is too short! But it is perfect. I feel like an addict waiting for her dosage and every time I see an update, I swear, I just scream and not give a shit whether my family thinks I am crazy
