I'm a bit confused, does the Mc like kinky sex or not? It's bin a while lol.

He’s doing what the ML asked him to since he likes being choked. MC did enjoyed dominating him before but along the way when he fell for the ML, he can’t do it anymore.

I guess to some extent, yes. However, I think he was overshadowed by fear of hurting Sihyun while having sex to the point of being in a state like his friend?
