Based on a tumblr post. Harry sends an owl thanking Narcissa for saving him and as the letters are exchanged, she realises how much this kid needs a mother, and she volunteers. Implied Drarry fluff on Draco's side. Includes other related short stories. Light fun, enjoy.

Four years after watching the love of his life marry another Draco is still reeling. What he and Harry once had now only exists in secret, stolen moments. A compromise in danger of breaking when a particularly difficult case crosses Draco's path. He enlists the help of his ex, causing them both to make the choice between happiness and destiny. (Sequel to Who Are You...?)

"The notion of what Potter suggested…. It sounded better than it should have. Why did that entice him so much? He was fairly sure he hated him. What was changing?" - Draco just wants to get through Auror training unscathed. He wants to prove himself. And apparently that has attracted some attention from an unexpected source in a way he never knew he desired.
