Help me. I can't remember the title of that Yaoi I read. It's an omegaverse about a young omega salary man working in a marriage matching company - or something like that. He has a client, an alpha who seems to be interested in our cute omega boy. It appears like they know each other but the alpha doesn't remember the omega so the omega pretends they don't know each other but in reality, the omega has a child and the father is the alpha - a child that the alpha isn't aware of.
