Im not sure I understand that story, because man was it a miserable read. The ML is a ruthless, obsessive, controlling abuser and MCs main emotional problem with all the rape and psychological manipulation seems to be that he's still insecure about whether the ML is in love with him.
Like SPOILERS but when youre getting raped in front of someone who has a crush on you and the thing that gives you the most emotional distress, is that you think the person currently raping you, to make a point about who owns you, might leave you some day...youre sending me straight to therapy.
