For generations, the Bernstein family has been renowned for their love of books. Elianna Bernstein, daughter of a baron from the Sauslind Kingdom, shares this passion and has earned the nickname "Bibliophile Princess." Offering a unique deal four years ago, Crown Prince Christopher Selkirk Asherald proposed to Elianna that in exchange for becoming his fiancée, she could continue indulging in her love of reading. In desperate need of access to the royal archives, Elianna agreed to the arrangement, despite not having any romantic feelings towards Christopher. Though Elianna is convinced their engagement is solely based on practicality, devoid of emotion, she anticipates it will end when she witnesses Christopher interacting with another woman. However, their relationship takes an unexpected turn, allowing them to explore their true feelings and develop a deeper understanding of one another.
