Born into the prestigious Count Charlier family, known for producing saints, Estelle has very little magical power and is mockingly called nothing more than a Saint in Looks Only. Her situation worsens when her greedy stepsister steals the title of Saint, leading to Estelle being sent off to a remote region. On the journey there, she is murdered by an unknown assailant, ending her first life. However, Estelle opens her eyes and finds herself transported back in time by one year. In this second life, her cold and distant fiancé, the Duke, has inexplicably changed his behavior and now whispers words of love to her, showering her with sweet affection. Now running a cute café with striking white bricks on the outskirts of the royal capital, Estelle navigates her second chance at life. Her primary problem is no longer her scheming stepsister but rather unraveling the mystery of why the formerly aloof duke is suddenly so devoted, all while dealing with his overwhelmingly sweet and possessive true feelings that he can no longer hide.
