I don't really know. I can understand both sides. I, personally, do think it's abusive and manipulative .
No it seems you don’t know what BDSM is, they have a purely sexual relationship and they mutually agreed to that, even if MD wants a emotional one. Chanwoo wants a mutual loving relationship which (at the moment) he doesn’t believe he could love MD and the fact that he told him that makes him a good person instead of him secretly being in love with someone else or feel like he’s missing something.
MD is manipulating Chanwoo into doing things that are clearly uncomfortable to Chanwoo knowing he won’t say the safe word or leave; he’s no better than Chanwoo’s ex’s who abuse him. Under NO circumstance should you hit your partner, especially if they did not consent to it in the bdsm play. And no one is obligated to return your feelings.
