Diagon Alley

After the war, Arya is strolling down Diagon alley when she runs into a white haired guy her age. He's cute, but by the way he holds himself, she can tell he's a Slytherin. As a Gryffindor, she instantly turns her attention from him, but when she runs into him a few more times, she begins to wonder if they're destined to meet.
