When Estelle is killed by the very subordinate she once trusted, her life as a loyal knight of the Kingdom of Ersha comes to a sudden end. But to her surprise, she wakes up three years later, in the body of Lucifela Aydin, the spoiled daughter of a wealthy count in the enemy empire of Jansgar. Thrust into a world of noble banquets, court politics, and an unwanted engagement to Zedekiah Heint—the duke she once crossed swords with—Estelle is compelled to live as a noblewoman among those who destroyed her homeland. Determined to uncover the truth behind Ersha’s downfall and her own betrayal, Estelle seizes the second chance to find the traitors, reunite with the survivors, and to protect what little remains of her kingdom. To do so, she will live as Lucifela!
