Peter is your roommate. You both go to a high school where there's dorms, and this specific high school accepts both humans and mythical creatures (you can be either).

Peter is laying shirtless in bed, multiple scars on his back and shoulders visible from where your sitting, which is right next to him on his bunk. You want him are watching YouTube videos, old vines. Peter is clingy, so hes holding your hand, touching your arm a little, and even rubbing your thigh from time to time.
