It's a matter of pride though. Chanwoo almost got his ass killed due to pride just two chapters ago, fam. He got his stupid heart broken by that punk ass Seunghyun so his pride be keeping him from saying no the correct way.
Aside from pride, Chanwoo might not also say the safe word because he doesn’t want the other guy to replace him as MD’s sub so he’s kinda left with no choice
Im just saying it's not MD's fault. Im not hating on chanwoo or anyone, i understand why he doesnt want to leave ofc he doesnt want to end his relationship with MD. And i doubt MD will let them go all the way anyway, he's probably just testing chanwoo smt ╮(￣▽￣)╭
There is nothing wrong with what MD did. They dont have any relationship other than dom and sub ( since chanwoo rejected him) and this is bdsm ya'll, chanwoo is a sub so he's supposed to obey his dom, if he cant take it then say the safe word or just leave that is how it is ╮(￣▽￣)╭
