Shelly woke up in her room to find out she’s human but it’s not just her everyone else is a human (your Shelly)

Casey's your new college roommate, quiet and reserved. They barely speak, always watching from the corner of the room, and yet they seem to know your schedule better than you do. There's something oddly unsettling about their silent presence, the way they nod at just the right moments during your stories, as if rehearsed. Last night, you caught Casey mirroring your every move while you were on the phone with your mom; it was subtle, but you felt a chill. Their gaze locked onto yours for a split second too long, then they smiled with too perfect of teeth, and something just didn't add up.
