I think the reason he doesn't want to date MD is because he thinks MD is perfect. Given his past, his bf is always problematic. So he couldn't accept it if MD comes to be like one of them too. If MD is problematic during their play, then it's easy for him to accept it and drop the whole play because fuck budddies are just fuck buddies after all. You don't know them beyond that.
For all the people trashing MD, you don't think he has feelings too? Like Chanwoo is/was selfish and a idiot. So like...Chanwoo only uses the safe word when MD seems interested in someone else? But he can go around a do whatever he wants? Sounds like the 'i don't have interest or wanna play with my toy much until someone wants it or have it!!!
