As a revered duke's daughter, Lupia had long been under the control of an unknown presence known as the System, which forced her to behave as a villainess. Her diligent efforts to become the next duchess and crown princess were systematically stolen by the sweet and seemingly innocent count's daughter, Falty, who took over not only Lupia's role but also her fiancé, the crown prince. Everything changes when a voice announces a release from the System, and Lupia's true consciousness returns. Now free from the game's narrative, she has no interest in revenge. Despite her path to becoming the crown princess being destroyed, she resolves to carve out her own future. Leaving behind the court that wronged her, Lupia moves to the Qua Kingdom, where her uncle King Rodd welcomes her. Determined to prove her worth, she decides to join the knight order, using her honed swordsmanship and the education she received as a prospective princess to pursue a life unbound by anyone else's designs. Meanwhile, the kingdom she left behind begins to crumble: without the influential House of Carmond, monster attacks increase and both the people and nobility grow distrustful of the royal family, while Falty's perfect ending begins to unravel.
