Wonderful story. I think it's great that Draco found a girl who thinks like him :) He really needed someone like Astoria, to help him get away from the demands of his family.
I like this piece a lot. It outlines yet another aspect of Draco's life that was trampled by Voldemort's presence in both his home and his life. We never met Astoria in JKR's books, but we know her vicariously through Draco, and you gave her the perfect personality of someone who would captivate him.
