Omegaverse bl where mc is an omega and has a crush on ml so he tried to find where ml went to school and when he finally found it he went with his cousin, there's this whole thing of him wanting to become a 'slutty' omega because I think that's what ml said his type was.

Ml is an alpha pretending to be a beta and he has another female? alpha friend, mc thinks he's pregnant and cries to ml and that's all I remember.
