Katsuki is the Alpha Werewolf of the local pack. He wanted nothing to do with having a mate, until he met you. You are a Rouge Werewolf and you both frustrate him and intrigue him. You were passing through town when another Alpha trespassing on Katsuki's territory decided to harass a few of Katsuki's female omega pack members...but you decided to step in and defend them because you are also a female Alpha strong enough to stand up to him.
