The story begins at a lavish end-of-term party where Randolph Victor, a red-haired young man, is startled by a public declaration of annulled engagement. Prince Edgar Roa Alexandros, the Crown Prince, loudly breaks off his engagement with Elizabeth von Blauvelg, a renowned beauty known as the "Ice Princess." Randolph, who has reincarnated from a previous life as a gamer, recognizes this as a trope from an otome game and decides to leave the party to avoid getting involved in the ensuing drama. He escapes with his attendant, Harrison, emphasizing their status as outsiders from a minor nation.
Randolph, now aware he's a mob character in an otome game, travels home. During his journey, he overhears rumors that Elizabeth has been accused of various wrongdoings, including threats and assault, against Viscountess Catherine Evans, a recognized saint and Edgar's friend. These accusations, supported by Edgar and his entourage, paint Elizabeth as a villainess.
Upon reaching the border, Randolph and Harrison encounter a situation where two women are being attacked by a group of men. Randolph intervenes, displaying surprising combat prowess. He rescues the women, one of whom is revealed to be Elizabeth, who had transformed into a powerful entity before Randolph subdued her. He brings Elizabeth and her attendant, Rita, back to his family's modest estate.
At the Victor estate, Randolph's father, Viscount Alan Victor, agrees to shelter Elizabeth. Elizabeth, now stripped of her noble status, requests employment as a civil servant, offering her exceptional intelligence and administrative skills to help revitalize the struggling territory. Randolph, recognizing her potential and the opportunity to develop his own abilities, agrees.
Meanwhile, Catherine Evans, the apparent protagonist of the otome game, is enjoying a beach vacation with the game's capture targets, including Prince Edgar. She revels in her position and Elizabeth's downfall, believing her actions are justified and that she will ultimately defeat Elizabeth, whom she views as a rival.
Randolph and Elizabeth, aided by the ancient sorceress Eleonora (who now inhabits Elizabeth's body), begin to work on improving the Victor territory. They discover a hidden ancient scroll containing "Production Magic," which, when combined with Elizabeth's immense magical power and Randolph's knowledge from his past life, allows them to refine monster parts into valuable materials. This ability, dubbed "Craft," becomes a key to their economic development.
However, their success in processing monster parts leads to an oversupply, overwhelming local merchants. Randolph devises a plan to sell the production technology itself to a powerful entity capable of mass production and market control. He chooses Elizabeth's estranged family, the wealthy Blauvelg Marquisate, who are known for their maritime trade and their deep affection for Elizabeth.
The Blauvelg family, upon receiving news of Elizabeth's survival and her situation, are overjoyed and enraged by the perceived betrayal by the royal family and Catherine. Marquis Lucian von Blauvelg, Elizabeth's father, secretly dispatches a mail bird to Randolph, arranging a discreet meeting to discuss Elizabeth's future and potential revenge against those who wronged her.
The story concludes with the Blauvelg family en route to the Victor territory, disguised as travelers, to meet Elizabeth and Randolph. The narrative sets the stage for future conflicts and alliances, hinting at the disruption of the original otome game's plot by Randolph's actions and the emergence of new power dynamics.
