Trapped in a world he didn't make:

Duo Maxwell had all the classic beauty trademarks. A heart shaped face, petite body, luscious curves, long chestnut locks, and amazing violet eyes that made every man drool in lust. There was only one slight problem with that. Duo was very much a man, himself. Since the age of seven he had been raised in an orphanage as a little girl. He knew it had been his girlish looks that earned him the label they had graced him with. Now he works as the CEO of a salvage company by day and as a professional cross dresser by night. With everything he's already experienced, what could have ever prepared him for the woman of his dreams?

Brought to a world she never knew:

Heero Yuy had always been one of the guys. At 6'3" with messy chocolate brown hair that fell about strong shoulders, a well-built frame that spoke of strength, and stunning cobalt blue eyes, Heero had the women dreaming of a chance with him. Only thing was, this Japanese American was all woman. She had always been told she looked more like a male than a female, which her previous boyfriends had been especially great at telling her. Her best friend soon shows her a world where looking different wasn't such a bad thing. Yet nothing could have prepared her for the vision in black she meets her first night.

They started out leading different lives, but fate brought them together. Now it's all about:

His and Her Circumstances!
