After a sudden reincarnation into the world of a novel she once read, Rinko Hanasaki finds herself as Raeliana McMillan, uncertain of her fortune. As the daughter of a wealthy baron, Raeliana had lived a carefree life until her tragic end at the hands of her fiancé, Lord Francis Brooks. Determined to alter her predestined path, Raeliana strives to annul her engagement with Francis. Yet, facing his stubborn refusal, she turns to Duke Noah Wynknight, the novel's leading male figure, for assistance. Leveraging her foreknowledge of the story, she intrigues the duke by proposing a pact: in exchange for her silence on his hidden truths, Noah must assume the role of her betrothed. Unaware of the repercussions of getting involved with a duke who only reveals his true self in her presence, Raeliana plunges into a web of unforeseen consequences.
