Beautiful codependency relationship, I think the mc is suffering from hypersexuality because of what the ml did in the past, that's why he became a maso*****. I love mc's character dept, how he knows that ml is not good for him but he can't get away and cut their relationship off. Because that's the thing with people who experienced sa, they tend to crave the very same thing that destroyed them. We still don't know much about ml, I hope his character will have as much dept as mc's.
