@Rilka I see this is your first omegaverse.... 1...Alphas, especially dominant ones need an Omega. It's in their DNA.
2.... instinct. They can be super in love with a beta, but if an Omega appears with high compatible pheromones, the alpha wont be able to resist. The only way an Alpha stops reacting to others, is after he bonds with an omega.
3....Betas can't stand passing a rut with the Alpha, while Omegas are built for that.
4....Alphas have an obsessive need to mark/bond with their mate, they can't mark a beta, but they can an Omega.
5....Pheromones
6....Babies, only omegas have higher chance of pregnancy and to survive the birth, and male betacan'tnt even have a kid
Etc.....etc...
