Just a Millennium or Two

Annemie van Denend was a goddess. Xiaodan Rén was a god. Too bad they aren't the only ones. As punishment for their creators actions in heaven, where all the gods of all tradition and culture reside, Xiaodan, the personification of Yin, was cast to earth with his wife and other half Annemie left to reside in heaven. However, every 9,000 years he gets the chance to make her fall in love with him again, and should he succeed they will be rewarded with an undisturbed millennium together on earth, before she is ripped away yet again. Every year they say they're going to fix it.
One millennium until they do.
