Author's Note: - is shot for too much Royai fluff-
It was the grandest theft in history, he had to admit, or, at least, the greatest theft he'd ever heard of. So easily done, without any effort, and there was no way to convict the thief. She was so quiet and clever, never leaving a trace, but he did know her identity. And he had to admire her for it.
The theft, you might ask?
Why, the theft of Roy Mustang's heart.
