A duke's daughter named Elizabeth Fontini is abruptly exiled from her kingdom after being falsely accused of behaving as a villainess. Rather than a punishment, she views her banishment to a remote rural church as a long-awaited opportunity for freedom and a peaceful life. Having retained memories of her past existence as a modern Japanese event planner, Elizabeth decides to apply her organizational skills and knowledge from her former life to her new situation. She sets about quietly reforming the church and its daily operations, with a particular focus on improving the quality of the meals, transforming the humble religious outpost through culinary innovation.

The story follows Elizabeth as she uses cooking to bring comfort and a sense of purpose to her days as a sister, revolutionizing the church fare with dishes inspired by her previous life. Her quiet life, however, is disrupted by the unexpected arrival of Leonid Guardhelm, a knight commander from the kingdom that cast her out. For reasons of his own, Leonid takes a keen interest in the exiled villainess and begins to frequent the church, introducing new social dynamics into her otherwise peaceful routine.

The narrative unfolds within the confines of the rural church and its surrounding lands, a setting far removed from the noble courts where Elizabeth once lived. The primary arc follows her journey from a disgraced noble to a resourceful and independent woman who finds fulfillment not in revenge, but in rebuilding her life through cooking and community. Her past knowledge of an otome game, in which her character was fated for exile, adds a layer of dramatic irony as she actively works to avoid further conflict and simply enjoy her new, slower-paced existence. A central relationship develops between Elizabeth and Leonid, whose presence complicates her search for a quiet life while also opening the door to new possibilities and connections beyond the church walls.
