In the capital city of the Great Zhou Dynasty, Mingyuan, the Minister of Rites, was holding a wedding ceremony for his legitimate daughter Minglan. Minglan looks dignified but is actually lively. She sneaks into the backyard to eat snacks when no one is prepared and bumps into the sixth prince Zhou Chengjin who has climbed over the wall. When the two met for the first time, Minglan mistakenly thought he was a thief and knocked him unconscious with a vase. After Zhou Chengjin woke up, he concealed his identity and claimed to be the palace guard "Zhou Jin". The two developed a wonderful affection while testing each other. At the same time, news spread in the court that the emperor intended to select a concubine for the sixth prince, and the major families began to make secret preparations.
