The daughter of the hero, Shen Qingyao (the head of Pingyang County), was married to the prince Xiao Jingheng due to the political interference of the previous emperor. After the death of the previous emperor, Xiao Jingheng succeeded to the throne, and Shen Qingyao was appointed queen. The emperor and the empress distrusted each other due to the political calculations behind their marriage. Xiao Jingheng was indifferent and distant from Shen Qingyao, and even used her to attack his family. Shen Qingyao managed carefully in the palace and tried to impress the emperor with her sincerity. However, she was repeatedly framed by concubines and implicated by her family, and was eventually banished to the cold palace. In the cold palace, when Shen Qingyao became terminally ill, Xiao Jingheng suddenly realized that he had fallen in love with her, but it was too late. Shen Qingyao died with hatred, and Xiao Jingheng spent the rest of his life in regret. Highlights: the sadomasochistic pull of two-way misunderstanding, the sharp conflict between politics and emotions, and the fateful tragedy of "loving without knowing it".
