My sister is my MATE?

Kyle is in love with his sister (Jessie). Little does he know that they are mates. Jessie is the alpha and Kyle is the omega. The pack hates him. He gets beaten/tortured by his dad and his sister tries to protect him. He has bullies that treat him like shit. His old childhood friend (Jade) exposes his secret to his dad. The only reason why he is living is because of his hope that his sister will love him back.
