just a hunch but I'm pretty sure MD is just playing around and never considered to let someone else take Chanwoo's place.
Umm.. One this is a story if you don't like the plot nobody is forcing you to read. Two chanwoo is a strong character and knows when to stop and leave when needed, md and chanwoo have a safe word and if chanwoo really hated it he would use the word. This is BDSM no where is there true abuse, chanwoo likes the pain and again if he didn't like it then he would say the magic word
For god’s sake, you can’t compare Chanwoo’s mindset to a normal personal’s because chanwoo is an abuse victim. Do you ever wonder why abuse victims don’t leave their abuser? Because they are manipulated, falsely assured, blindly by love towards their abuser. BDSM is a play where everything must be consensual. The last time I checked, Chanwoo did NOT consent to being choked, slapped, or kissed by a stranger as a play.
BDSM and social interactions are a different thing tho? MD is basically manipulating Chanwoo although he often said that he did NOT want to do that. and as Jane said, Chanwoo is an abuse victim, which MD knowingly uses. He is just as much of an abuser as Chanwoos ex but on a mental stage. this is not "that kind of manhwa, so you should not read it", some things like speaking good of things like abuse, manipulation or rape have got nothing to do in any kind of manhwa.
Kacchan... that's some real character developement there alright(๑•ㅂ•)و✧
