the mc was triggered in high school by his destined mate, but claimed by his best friend. Then later, the omega who lost their memories was actually the ML's destined mate, and he reacted to him. Eventually ML rejected him, making his condition worse. But eventually that omega gets with the guy who was s'posed to be the destined mate of the og mc?
