In order to clear her family's grievances, the heroine Jiang Sui disguised herself as a man and entered the imperial examination, and won the first prize in one fell swoop. However, she was named the prince consort by Chu Jinci, the eldest princess who seemed weak and unable to take care of herself, but was actually powerful. While Jiang Sui was covering up his daughter's identity and tracing the truth, he also had to deal with the eldest princess's endless temptations and "molestations." The two went from being a fake couple who were suspicious of each other to becoming true allies who cooperated tacitly in the court. They fought against treacherous ministers, foreign relatives, and leveled the border. At the critical moment when Jiang Sui's identity was exposed, Chu Jinci tore off the disguise of being sick and used thunderous means to protect his wife and reach the top. In the end, the two of them took charge of the country together and created a prosperous era for women to serve as officials.
