A diplomatic marriage decreed, Xiyue’s Princess Li Ming Yue is off to the neighbouring state of Beixuan to wed Li Qian, Prince Zi. The highly-disciplined Qian meets the free-spirited Ming Yue resulting in a poor first impression. Reluctant to get married, the two antagonise each other in hopes one of them will break off the engagement. While hypnotising Qian, Ming Yue causes lost memories resurface. Curious about the trigger for his amnesia, Qian suggests a marriage of convenience, providing Ming Yue help him regain his memories. Qian’s brother Li Xun would prefer those memories remain in the past, as they would only impede his schemes of becoming Crown Prince. Which brother will make the throne his own?
