Shen Qing, the eldest princess of Dayan, and Lu Yunzheng, the general of Zhenguo, were married for a year but have been separated since then. Two years after Lu Yunzheng's expedition to the north of the Great Wall, he returned triumphantly and brought back a woman, rumored to be his Bai Yueguang. Everyone thought that the eldest princess would be left out in the cold, but Shen Qing unexpectedly heard Lu Yunzheng's heartfelt voice, only to realize that the general was affectionate and restrained, but he was duplicitous. Shen Qing took the opportunity to move out of the general's mansion, and Lu Yunzheng followed him secretly but did not dare to show his face. Shen Huai's rebellion revealed his true identity, and Lu Yunzheng led his troops to protect the country. After this battle, the two became frank with each other and all misunderstandings were eliminated. After Lu Yunzheng pacified Nanzhao and returned home in triumph, the couple finally found a connection and stayed together ever since.
