Shen Zhiwei was forced to marry the powerful "eunuch" Pei Xuan. She thought she could live a stable life, but she accidentally discovered the secret that he was not an eunuch. She pretended to cry and got through, but was tricked at the palace banquet. Pei Xuan protected his wife in public and took her under his wing. As the struggle for imperial power intensified, Pei Xuan confessed his ambition to change the dynasty, and Shen Zhiwei chose to side with him. In the end, Pei Xuan supported the young emperor to ascend the throne and become the regent. The two put aside the disputes in the court and retired to the south of the Yangtze River, where they stayed together for the rest of their lives on the small bridge and flowing water, fulfilling their promise of "win the heart of the same person and stay together forever".
