Help me find this omegaverse bl PLEASE

It's about two co-workers and the omega gets pregnant (like most do). The omega was tall, had black hair, and was buff while the alpha was blonde. The omega and alpha got drunk and in the recent chapters found out about the omegas 's pregnancy. It has like 20-30 chapters out so far I think. I do know that the omega doesn't really want the alpha in his kids life. I know there are a lot like this so please help me ┗( T﹏T )┛
