Defeated in the battle for the throne and falsely accused of murdering her stepmother, Jozu, the first princess of the great nation Dolman, is given a punishment that is essentially exile:
a marriage in name only to Emilion, the king of the small frontier country Ronino.

Rumored to be a villainess, Jozu's true intelligence and grace soon win the hearts of the people of Ronino, and little by little, Emilion himself begins to accept her…

Thus begins a Cinderella-style romance where she carves out her own destiny!
