Searching for this manga yaoi

The author has a particular style of art. It’s a black and white Yaoi manga. The ML is a manager or something at a sex work place and the uke has lgjth hair and he goes to work as one but only does it with the manager ML. And they start to date or something, and the black haired ML apparently is still at work and teaches other new sex workers how to do certain services.

And the uke gets jealous and they argue I believe. And later the Seme comes back smelling like a different shampoo. The uke is angry and says, “did you sleep with someone?”
And the Seme is like, “I thought we would but we didn’t. Don’t worry.”

This is the same author who made the popular alpha omega story where the omega who had hoped to be an alpha turns out to be an omega, and his childhood friend who he drifted apart from is an alpha.

and the cool friends he hangs out with are all alphas and betas, making him insecure and tries to hide it. But the alpha in the friend group finds out and tries to rape him. But the childhood friend stops it and does it to the uke in their place.

They get together and time passes. They’re adults now and the alpha who was about to rape uke at the time had apologized. He also meets another uke with long hair and that 2nd uke is fated partners with the childhood friend of first uke. And shit happens.
