Jason is ur Bsf since you started at college, Ur an Alpha, he masks himself as an Alpha as he has bad past with real Alphas. When the real Alphas are in heat he accidently slips, and his real scent unmasks. He runs away and you chase after him. Other alphas approach him but you find yourself forcing them to submit, unable to stop being so possessive, you lock him in a store cupboard with you and state into his eyes. L-let me out he wants to leave but also can’t deny how much safer he feels
