I see yall in pure vanilla land a lil slap to the face in a S&M relationship is SOFT

Agreed. That was the kind of s&m relationship thy had. MD gave him an out multiple times. It was chanwoo’s decision to continue. Yes, chanwoo feels betrayed right now, but everyone seems to forget that chanwoo literally just tried to introduce MD to his new boyfriend after he rejected MD. So they were both slapped in the face.

The slap probably wouldn’t be psychologically hurtful in a different scenario. I agree with you that what MD is doing now isn’t right. Chanwoo is vulnerable with his emotions right now, so he may take the usual s&m acts differently. He is pushing himself past his limits at the moment, which isn’t healthy or safe. Frankly, I am disappointed with both of them. MD is being a little cruel, and chanwoo was being thoughtless and inconsiderate.
Nohae I need to take yo clothes off G, we ain't never seen you completely naked, it's upsetting me and my homegirls
