MD is the one I feel the most sorry for, the guy has to deal with both their bs

MD created very toxic play where Chanwoo feels obligated to agree to anything because of conditions. He is mixing his grudge and feelings with play. Which is just wrong. There is serious power inbalance. It is so much worse than Vhanwoo being insesitve because he wanted to know if they can continue their relationship although he got in relationship.
He is making Chanwoo participate in scene with the guy who just used him and rejected him. How insesitve is THIS?

Guys its a joke, I don't feel sorry for any of them, but lets not kink shame. Chanwoo is insensitive as he knows MD wants a serious relationship with him yet he wants another partner whilst doing kinky plays with MD. The former sub is a jerk too for leading on and lying to Chanwoo. I don't blame MD for his little dom plays but it is not right to bring in personal feelings when neither party is ok with it but on the other hand, he did repeatedly confirm consent from both.

There is something like strangulation kinks out there, so Chanwoo is probably into that, it's full-on consent because MD asks him constantly if he is ok with his plays or not. It's Chanwoo's decision to play along with him. You making assumptions on Chanwoo not giving full consent is baseless in my opinion (he is an adult and has been in many relationships to know what he's into and not like how when his partners become overly abusive he calls it quits so he knows his limits).
Stalker-kun is so kyuuute!!!!
