have you read omega complex and alpha trauma? those two are really good. then imo, the best omegaverse is love shuttle, though many people don't like it/read it because of the artstyle. but the story is a 100/10 (except the side stories. DONT READ THOSE PLEASE) also another good one is romance not romantic!
