Song Nuan, the legitimate daughter of the Zhenguo General's Mansion, was framed by the state counselor Chen Yi, causing everyone in her family to be wronged. She also had her animal veins sealed. She turned into a white cat to survive on weekdays, and only temporarily changed into a human form during the full moon. Desperate, she broke into the White Tiger Emperor Xiao Che's Heart-raising Hall, and was discovered by him. Xiao Che tried his best to protect her, and the two of them worked together to investigate the irrefutable evidence, clear the grievances of the general's palace, find ways to break the forbidden magic, and protect her in both directions during the turmoil in the court. In the end, the injustice was cleared, the forbidden magic was lifted, and the emperor and the empress stayed together for generations.
