(Found it now but i wanna keep this up lol)
It was like omegaverse with s&m with the uke being like, unwilling to give into his desires always pulling away when he feels happy or good, and the ml is a like, I forgot what it was specifically but it's like rent a girlfriend except it a guy and he's only there for the night to make you feel good and he's gone, they met-up at a hotel and Mc was having regrets aabt doing that but the ml gave him commands that omega physically can't resist,(just saying simple words but with alpha pheromones and aura ahh) and he basically made him forgot all about it and they fell in love and soon after he met his ex again, Mc ran out o suppressants and ex wanted to help him by well yk, and ml wasn't having it and took him back (Mc was giving him the cold shoulder at the moment bcs he regretted it all) but later they made up and had blindfolllded sexy sex, consensual BTW and bdsm yk.this is probably to long lol, mb.
I found it!! I found another subdom verse thing that I read on bato and found a tag like what you said and it was on like the 2nd or 3rd page https://www.mangago.me/read-manga/yarashiku_shitsuke_kete_itoshite_ageru_dom_sub_universe/

I remember the Mc was like white after, with a few moles here and there but he hated them because in his past life purity/spotless skin was highly valued, even their hair was white, and the enemies had all black hair I think I don't rlly remembr them, but Mc was an editor and ml was on the enemy side and he was a prisoner, he was the author of a really popular book in his new present life, in the past life Mc was killing himself using time magic to read in peace without anyone interrupting him because he paused time for himself, in the last chapter I read they were at a bathouse I think.
I have read this but doesn't remember the name.
