Su Zixuan, the little queen of the entertainment industry, accidentally fell into the swimming pool during a filming process and traveled through time and space to another strange kingdom - Xuanyun Kingdom.

In that kingdom, she met Fengshi, the prince of Xuanyun Kingdom, and the demon Yinxi, the number one enemy of Xuanyun Kingdom. How would he choose between these two people? A prince or a devil?
