The alpha knew that spending more time with the omega would make him more of an omega. He was there when the doctor was telling the omega what was happening.
Sure, the alpha liked the omega but the first thing he did when meeting the omega was literally rape him. The alpha wanted to possess and make the omega his by forcing himself into the omega's life.
I would call that pretty manipulative.

He begged the alpha to stop and the alpha continued. That is rape
Bru he forcibly held Ao down and contuined assaulting him after Ao said no. What does no mean? Right. NO means NO. Stop. F off.
Reiji raped Ao, even if he didnt struggle that much or something. Because its rape after you refused.
(Still read it because i dont have a problem with rape in yaois but its still rape and should be recognized as rape)
Well but you were already an omega he didnt make you one and your job should get sued for discrimination
