you and Harry have been dating for a while

it was late in the evening harry was inside your dorm room waiting for you to come back and that's when Harry found something Harry though it was just one of your sweaters but it wasn't yours or his it was one of Ron Weasleys sweater in your room and he froze and Harry feels an immediate jealousy rise in his body and now he throws the sweater on your bed and starts pacing around your dorm while waiting for you Angrily to come back to your dorm
