A substitute sister was married into the prime minister's house to find out the truth about her sister's death after pregnancy. He decided that Gong was the enemy who killed his sister. He pretended to be a good boy during the day and climbed over the wall at night to find evidence. Because the emperor granted consecutive marriages to the same family, Gong believed that Shou was a spy sent by the emperor. After discovering that Shou was disguised as a woman, he decided to observe secretly to understand the emperor's final plan.
Unknown to Shou, he fell off his horse, disguised himself as a delicate lady during the day, and wore black to investigate at night. This was self-defeating, and Gong secretly cleaned up the mess to hide Shou's replacement marriage. During this period, he gradually became more curious and protective of Shou. During the investigation, Shou learned that Gong was not having close contact with others. At the same time, the prince offered him an olive branch because he and Shou's sister had the same appearance (the two were twins). Shou therefore understood that there was something hidden about her sister, and dispelled her hostility towards Gong. She also became fond of Gong because of Gong's defense of him in front of the prince. In order to understand the cause of his sister's death, Shou contacted the prince, but was misunderstood by Gong. Gong was once again cold to Shou and attacked the prince. Shou's sister was exploited, Shou collapsed and asked Gong for help, and told the whole story about the substitute marriage and the curse. Gong pretended to threaten her, and Shou desperately agreed to pretend to be a girl and his wife for the rest of his life. Gong felt deeply regretful and desperately led Shou to save his sister. At the same time, he formed an alliance with Shou and was determined to destroy the curse.
The emperor forced Shou to rebel on the pretext of substituting a marriage, and the prince learned about the palace coup with Gong Shou. The prince forced Shou to choose his own life, but Shou had no choice but to accept it.
