Maybe not exactly what you're looking for, but Unsleep is of my favourites, and the main couple is equally freaky for eachother
I don't think that qualifies they started off very rocky and were rocky for a good while, the communication isn't really clear and it got to a point for me where the aggressive sex every chapter turned me off (which ig u can't blame for a smut yaoi). Equally freaky yes but everything else is like. Orange flag, maybe yellow if I don't wanna be too harsh
There are some misunderstandings, but they do talk about stuff so the misunderstandings don't last long. They are very far from an 'orange flag', despite the rocky start. I rarely see the kind of physical intimacy they have in Unsleep in other series.
If the amount of sex is the problem, then I can see how it's not the series for you.
The amount of sex isn't the problem it's just super aggressive in a way that is very unlike the feeling this series gives me [like yeah theyre freak4freak but at times the top just loses control of himself mindlessly its jarring]. It's a great read but it isn't similar to this at all (hence why it isn't the series for me or a proper recommendation) (also I'm not trying to argue or anything, im just being clear bc idw ppl reading to get into unsleep thinking they're getting something similar to this series)
Can anyone recommend stories like this with a character like hangun???? Sweet,devoted, not psycho, treats his guy well, freaky af but not in a borderline sa way, and communicates clearly???? Nothing is scratching the itch like this manhwa rn
