Let's see...
MD crossed the boundaries of the play three times. He mixed his own, personal feelings, anger with the play which is just unacceptable. He nearly strangled Chanwoo to death because of anger after rejection. Then he coerced him into the play with other sub. Just after he was betrayed and rejected he put ultimatum that he will abandon him too if he won't participate. Clear emotional manipulation, it's no consent if it's impacted by condition. Chanwoo was pressured to take part in the play with the guy who just used him. He was anxious, disgusted and only stayed in the play because of ultimatum. He is abuse victim and MD knows that but he out him through another super toxic and traumatic experience because he wanted to see his reaction.
It wasn't BDSM it was abuse disguised as one.

BDSM IS LITERALLY CONSENSUAL ABUSE LMAO. The only reason he was probably pressured to go the play was being he was too ignorant about his feelings towards MD and didn’t want to lose him. He told him he could leave during the play but he didn’t, he wasn’t just going to “abandon” him like you said. And if you don’t like something, you say the safe word, it was said and MD stopped immediately. You probably just don’t like the whole idea of BDSM because none of it was out of context or to an abusive extent. Also both of them mixed feelings with the play, so you can’t really just blame the character MD. I understand what you’re trying time say but you have to keep in mind that it was still a contract and MD have every right to do what he did because he was basically the employer and didn’t usually stick to the same sub for too long.

OMFG. The most important in BDSM is clear consent. Consent pressured by ultimatum, conditions IS NOT CONSENT AT ALL. Seriously it's really simple.
MD broke the contract HIMSELF. He agrees about having romantic relationship beside their play and he then he confessed. He continued play after recording and they agreed only to recording play. He strangled him nearly to death because of anger after rejection

He literally reminded him if he won't participate or won't continue it's the end of their relationship. He knew Chanwoo didn't want to do that (he was asking if he really HAD TO do that), he saw haw disgusted and anxious he is and he still continued and pressured him to have a scene and make out, touch the guy who just treated him like trash and used him. It's abuse. And then he slapped him when he saw how uncomfortable he is and how much he doesn't want to do that. It was emotional and physical abuse. This scene didn't have to do anything with BDSM play. BDSM is about consent, full, clear consent, safety and satisfaction, pleasure of both parties. We didn't see any of that in this pseudo play.

Like I said he was the employer so he wasn’t in the wrong when he told them two to play to see which one was better. I get what you’re saying though
, but we have really different perspectives and I don’t want us to get mad at each other for it so I’m not going to say anything because I don’t want us to argue over two fictional characters):

1. He wasn't interested in the other sub in the slightest.
2. It doesn't work like that, especially if the other party didn't want to. If he really wanted to change sub then they should have mature conversation about the problem and see their options.
3. MD many times crossed the boundaries as an employer.
I agree to disagree!
To the people getting mad at MD. Y’all do you realize they were at play and both of the bottoms agreed to it? They only reason someone should get mad is if MD didn’t stop when he said the safe word. He didn’t even need to apologize because BDSM isn’t vanilla sex and it does get really hardcore.
