I’m trying to find a yaoi manga...

So... it’s an omegaverse... where... the omega is lovers with an alpha however... his fated pair arrives... and asks him out... however although he was attracted(bc of the pheromones) he refuses... his boyfriend looks up the omega’s fated pair and found out (oh he’s a hoe and an asshole) and tells the omega right in front of him and omega chooses his boyfie over fated pair and boyfie bites him that’s what I remember...
