2 Alphas but 1 Assassin (Werewolf AU & Norray)

Everyone's werewolves and is assigned to either be a Alpha, Beta, or Omega based on the blood type they have. One day Norman and Ray get their results which turns out that they're both Alpha's. But before this Ray was a assassin who only killed the toxic werewolves or some of the Alpha's and Ray falls in love with his best friend Norman but doesn't want him to know the truth. Ray fakes being a Omega to hide being the assassin since they started suspecting the Alpha's. Norman also fell in love with Ray but how will he react when he finds Ray's truth about himself?
