Harry Potter: A Double Bluff

Harry Potter died in the duel with Voldemort three years ago. How will the survivors, especially Draco Malfoy, who was left scarred by their conflict, regain their confidence and laughter as they carry on with their lives? Pairings: DH, BZ. I might add more if I get carried away. This is a slow-burn story, and there may be some fluff [please don't believe the second half of that, QAQ]. Setting: A modern world without magic. Proceed with caution if this is a dealbreaker.
