The willful and passionate Princess Chu Yuan of Changling falls in love at first sight with the aloof and ethereal priest Yujingzi. Faced with his constant dodging, the princess willfully pursues him, only to give up in a huff after running into walls time and again. Yet ever since Yujingzi left, Chu Yuan has been haunted by bizarre dreams every night, suffering greatly. It is then that she learns the restrained and observant priest is actually a descendant of the snake god who protects the Sheng State. Past entanglements and misunderstandings are gradually uncovered, and the two resolve the knots in their hearts. Chu Yuan sheds her impetuousness and learns to respect and cherish; Yujingzi lets go of the shackles of being a god and confronts worldly love. Crossing the difference in human and divine lifespans, the two reach a two-way reconciliation, guarding and staying with each other, ultimately protecting their family, country, and a love that deepens with the passing years.
