Queen Marie lives a life of luxury and decadence, spending her days lording over her subjects and her nights with a harem of beautiful women. Her tyrannical reign, however, comes to a brutal end when her people rise up and send her to the guillotine. As the blade falls, Marie does not die. Instead, she inexplicably awakens one year in the past, on the day before her original rise to power.

Marie soon discovers she is trapped in a seemingly endless time loop. No matter what actions she takes to change her fate, she always ends up back at the guillotine within a year. Desperate to break the cycle and survive, she learns that the only way to avoid her execution is to alter the personal relationships that seal her doom. Her solution is to win over the countless women who despise her, not through policy or kindness, but by seducing them one by one. The story follows Marie as she uses her royal charisma and past experience to build a yuri harem, navigating romantic entanglements with the very women who once wanted her dead in a bawdy fantasy comedy.

The central character is Marie, a selfish and domineering princess whose past cruelties are the root cause of her downfall. Facing a persistent death loop, she is forced to transform from a tyrant into a strategic seducer. The supporting cast is comprised of the numerous women who hold a grudge against her, including former political rivals, spurned lovers, and resentful subjects. The story is set in a fantasy kingdom where courtly intrigue and noble houses provide a backdrop for Marie's survival scheme.
