Cai-Sheng is a young celestial fox demon being raised by a bevy of wild fox demons who hope she will master the celestial ability to transform into a male and save them from extinction. One day, she sneaks out to the nearby village, where she befriends a little boy and girl. When they save Cai-Sheng from a dog attack, her caretaker marks them with special symbols that will not disappear until Cai-Sheng returns and repays her debt to them.
Two hundred years later, Cai-Sheng meets the reincarnated boy and girl and decides to repay her debt to them by trying to matchmake the pair. But things get complicated when the reincarnated girl falls in love with Cai-Sheng's male form!
