I like CPs with strong love but for these two, love didn't exist. Even the ML admitted that he didn't love MC at the end. He didn't care if MC hated him or loved him. It feels to me like he wasn't even s*xually attracted to the MC. He was simply obsessed with the idea of being around the MC and the MC just got used to the ML. I think they call it Stockholm Syndrome?
MC always fought and cried during s*x but enjoyed it inside. I found it very problematic because dry violent an*l is painful, even if the MC is a huge masochist, I doubt that anybody would enjoy something like that. Then there's the ML. It was written that the ML was disgusted by the constant stream of internal thoughts from the MC and didn't want to it, so how did he preserve a h*rdon to f*ck the MC multiple times (sometimes for days) ? And this happened in nearly every world?
