I'm searching for a story but can't remember the title or character names. It's about a boy who is an omega and a "friend"(?) who is an alpha. The alpha becomes famous well the omega hides the fact that he is now pregnant. They don't see each other for a long time, but when they do, they have some fun and the omega gets pregnant again. Finally the eldest child figures things out and confronts the alpha, who finally finds out what happened.

I believe the title you are looking for is called Daiya no A dj - Single Mother Eijun ?

Shoo, Nothing to see here!

Yes, thank you so much.
