Well yeah the bar is in hell and I'm aware that this is fictional and all.
But first if all the consent is unusually relatively leaking which isn't great. The Dom just does what ever he want and assumes the Sub will be into it. Can't remember them having a safe word and mind you the bottom started of as a virgin. The pace at which he started enjoying it is wayyyy to fast. And wayyy to hard from the beginning. You usually start slow ( especially if you have no experience) to figure out what you like.
Additional( at least for me ) the top isn't doing a good job being a Dom. Like yeah I have to point it out again. The sub started of as a VIRGIN and that Dom is a lot of things but emotional mature isn't one of them

The pace depends on the sub. if you reread the webtoon, yuan was eager to try everything. If he wasnt, he would have told his dom. I see this as them testing out limits especially yuan's. It could be better, especially their first time but then again, the sub has all the power here and lets not forget the dom asking for feedback after a play session.
As a representation of BDSM, this story kinda sucks. But I will let it slight since the top is enjoyable to look at
