Fu Ziyuan is the most common mute seller of steamed buns in Xishi Street, and he and Li Shuangshuang have been childhood sweethearts since childhood. He had been in love with Shuangshuang since he was a boy, but he felt that he could not speak and was not worthy of Jing Zhaoyin's only female police officer, so he helped other young masters connect with Li Shuangshuang. That day, a mysterious carriage came to the West Market Street. The person who got off the carriage was Gong Litou, and he was invited to the palace. It turned out that the person who invited him was the princess who had beheaded the prince-in-law with her own hands. The princess said that Fu Ziyuan looked exactly like the prince-in-law who had died with him since he was young. She asked Fu Ziyuan, "Ziyuan, are you willing to stay with me?" Fu Ziyuan was very embarrassed, but Shuangshuang's bright faces popped into his mind.
