it was a black and white manga that started at this school for alphas and omegas like a boarding school for rich alphas and omegas were kinda just passed around?? one of the tall top rich class president alpha guys ends up becoming an omega and gets a hysterectomy. after high school he dates an omega that he went to high school with and despite being an omega himself he continues to act as an alpha even though it’s common knowledge he is an omega. I think at his work his employee jerks off to him as he sleeps. would love to know the name thanks!
