Matsurika, a woman serving as an officer in the Inner Palace, possessed a unique talent - an exceptional memory. When she agrees to assist in a practice marriage meeting for a notable family's son, she is surprised to find that the suitor is none other than Emperor Hakuyou himself. Intrigued by Matsurika's remarkable ability, Hakuyou proposes an unexpected challenge: to pass the civil exam. Thus begins a Chinese-style Cinderella tale of an emperor and a girl, filled with twists and surprises.
