Be strong !
I think MD pushed Chanwoo this far because he was afraid that chanwoo don't respect his own limit (aka be bullied/hitted by his former boyfriend). He tried to push chanwoo to say the safe word but Chanwoo don't seems to know when to stop, chanwoo is his own threat, this why he stopped to see chanwoo.









Damn I read it all because I hoped for some redemption arc or whatever, but mister the actor is the embodiment of a real narcissist manipulating by blowing cold and hot with the cherry on the top as the physical abus on top of the emotional one.
Thanks it’s a just a story, but dear reader this is cannot be a healthy relationship, the roots of this relationship was way too fucked up from the start. Please if you recognised those patterns and red flags seek help to get out of this toxic situation, love
