It's a yaoi omegaverse. Where i know the alpha had black hair was cold-hearted and was an author or something like that. In the ending chapters the omega had a friend who was pregnant and then the main omega was pregnant as well and they had their babies pretty close together cause i remember the babies would cry when they got seperated. And that's pretty much all i remember, omega might already have a baby but might not as well
