After the death of modern agent Shen Anruo, she traveled through time and became the legitimate daughter of the Minister of Nanzhao. After waking up in the night of flowers and candles in the bridal chamber, she found that her husband Fu Chengyue was having trouble with others. Shen Anruo quickly fought back. During this period, she met Shang Xuanche, the prince of Tianyuan who had first sent a delegation to Nanzhao, and met on the street for the first time. The two of them had a romantic relationship by chance. Afterwards, Shang Xuanche lived in the courtyard next door to Shen Anruo as the prince and kept in touch with her as Lu Jinye. During this disguise game, he was gradually attracted by Shen Anruo's liveliness, intelligence and strength.
