I don't think that what MD did was wrong, Chanwoo agreed to the play so he had to be prepared for everything, they have their safe word so it's ok to stop if he feels like that's needed. Anyway Chanwoo already rejected MD and had boyfriends while being his sex friend, so I don't think that MD did anything wrong here.. He has the right to play around with anyone and do whatever he wants. If Chanwoo just said that he was uncomfortable with the play or that he didn't want to do it, I'm sure that MD would have agreed, so in my opinion it's Chanwoo's fault for not being honest about his feelings towards MD.
It's just my opinion so not everyone has to agree with it ヾ(❀╹◡╹)ノ~

Why does everyone blaming Chanwoo just suddenly forget he’s an abuse victim. Abuse victims have the hardest times saying no or refusing, and with Chanwoo’s stubbornness, it makes it worse. Saying that Chanwoo had the option to refuse when he’s mentally unstable and accustomed to being abused is insensitive to abuse victims. Abuse victims usually cannot refuse their abusers because they are bound by something; whether it is love, manipulation, or fear, there is something holding them back.

The thing is why would you framed MD as abuser? He has no obligation to cater to Chan Woo every needs.
This is consented sexual relationship, MD just doing things like he would usually do. It's not like they have vanilla sexual relationship.
Things didn't ended up like what Chan Woo wanted, but it's not serious enough to call MD abuser.
Yes MD IS CALCULATIVE. He tried to gauge Chan Woo reaction, but that's justified.
But he stopped as soon as Chan Woo said the safe word. If he's abuser, we would've seen something worst.

As the dom and the person in the position of power, it is his obligation to cater to the safety and comfort concerns of his partner. Anything done without consent during a bdsm play where pain is being inflicted, is abuse and even rape. Abuse comes in many ways, shapes, and forms. MD was fully aware of Chanwoo’s discomfort (“Do I really have to do this?”) and even knew very well that Chanwoo is stubborn and doesn’t like saying the safe word even when MD put Chanwoo’s life at risk when severely choking Chanwoo.

Also, before you reply with other nonsense.
Let me stress this, MD and Chan Woo relationship although it is dom-sub relationship, it wasn't a relationship that is instilled by fear.
Chan Woo have a say in every kinky stuff they do.
And obviously, Chan Woo doesn't love MD (at least until recent chapter, he's not aware).
They are strictly in pleasure only kinky relationship. Is it toxic? No!
The main couple relationship was much worse compared to these two.
AGAIN I don't see why people expect MD to be a foolish nice guy for a person who doesn't even love him.
LOVE EACH OTHER ヽ(`Д´)ノ
