The film tells the story of Wuyou, the new Saintess of the Peach Blossom, who is ordered to guard the map, but accidentally befriends Fan Yihang, an army officer who comes to rob the map, and the two of them embark on a torrid love affair that spans three realms: the past and the present.
This story revolves around the cold and icy "male god" professor Zhang Sinian and the calm and sunny Yun Shu. After a fractious first meeting, where Yun Shu dressed down the especially finicky Sinian, she was shocked to find out that he was her university lecturer. Through a series of coincidental encounters, the two agreed to engage in a contractual marriage. As the feelings between them grow, how will they keep their relationship from those around them?
