Draco Malfoy/Golden retriever

You and Draco met in one of the train cars heading to Hogwarts. You stroked his head while Draco laid on your lap.

At one point you got up to go to the bathroom.

• Where are you going? Stay with me, don't leave me... — Draco took your hand and sat you down again to put his head on your legs. — I need attention from my girlfriend, don't go.
