Set in a world inspired by ancient China, the empire's five clans present their young women as potential imperial consorts. They all compete for the coveted title of empress. Kou Reirin, a gentle and graceful maiden known as the "butterfly" of the court, is expected to win the heart of the crown prince. However, during the grand Lantern Festival, an envious "court rat" called Shu Keigetsu unleashes her fury on Reirin, leading to her imprisonment in the dungeons. In a surprising turn of events, Shu Keigetsu swaps bodies with Reirin to claim her desired position within the court. Despite facing several challenges, Reirin discovers a newfound strength within herself and stands her ground, refusing to surrender, even in the face of certain death.
