Larcy, princess of the Kingdom of Berry, faces execution after being accused of starting a war with the neighboring Chariot Empire. Her own family, including her sister Nicola, betrays her and reveals she is not a true princess. However, at the moment of her death, Larcy is sent back in time by ten years. Armed with the knowledge of her previous life, she chooses the path of revenge, abandoning her kingdom to marry her greatest enemy: Jevon Van Verben, the ruthless emperor of the Chariot Empire known as the Tyrant.

The story takes place between the Kingdom of Berry and the Chariot Empire, where political maneuvering and personal betrayal take center stage. Larcy, nicknamed the Princess of Bats, is a practical woman who now uses her cunning to manipulate events from within the imperial palace. Emperor Jevon is a cold and powerful ruler who maintains multiple concubines, yet he grows fascinated by Larcy’s defiance and bravery. Living in the imperial court, Larcy must navigate the dangers of the harem while executing her secret plan to destroy her former family.

In a notable early narrative arc, Larcy marries Jevon and immediately clashes with his existing concubines. When the sixth wife, Camilla, learns that Larcy has accompanied the emperor on an outing, she retaliates by cutting the mouth of Sing, Larcy’s only servant. Instead of cowering, Larcy burns Camilla’s face in direct retaliation. When Camilla’s family, the Dukes, sends a letter of protest, Jevon ignores them. He is impressed by Larcy’s audacity, though he simultaneously grows jealous of the deep loyalty that inspires Larcy to protect her attendant so fiercely.

As the narrative progresses, Larcy uses her position as empress to gather power and information. Her sister Nicola, who had been groomed from birth to become an empress, represents the betrayal that fuels Larcy’s revenge. The romance between Larcy and Jevon develops amidst the violence and scheming, as two broken individuals find common ground. The series is a love romance revenge drama that follows Larcy’s quest for vengeance while exploring whether she can truly fall with the emperor she married for power.
