I've been looking high and low for any Alpha x Beta pairings in the Omegaverse (Yaoi pairings only).

Most of the ones I read were all A x O and I have been wanting to read one where a Beta ends up with an Alpha, instead of an Omega being in the pairing. Anyone has any recommedation?

Well there's the second couple of Kashikomarimashita, Destiny. The first couple is the usual A/O story but the second one is A/B gold.
