[HPAD] Travel Companion: The Companion of a Soul

At Bill and Fleur's wedding, Harry Potter meets a strange red-haired young man. He seems to remember nothing, not even who he is, yet when he sees Harry, who has taken Polyjuice Potion, he blurts out Harry's name. Harry seems to be the only person in the world he remembers. By a twist of fate, Harry takes him away from the wedding, and he gets caught up in the trio's flight and their quest to destroy the Horcruxes, becoming a companion who shares life and death with them. Throughout their perilous journey, he stays by Harry's side. Together, they gradually uncover the unknown past of the mentor Harry loves, and in the end, the young man discovers who he really is... Harry/Draco, no explicit content and no alternate pairings. More tenderly romantic than purely warm and affectionate.
