Sarah, the eldest daughter of the rural noble family Fahren, lived a modest life from a young age, taking care of her younger sister Alice in place of her busy parents. Alice is known as the White Lily of the Fahren family, while Sarah is referred to as "the other one" or "the White Lily's caretaker." She is forced into an unwanted engagement with the second prince, Gerard, but a year later, he unilaterally breaks off the engagement, claiming he has found "true love," and then falsely accuses her of attempted assassination and banishes her. Exiled to the remote town of Randall, Sarah enjoys her carefree life alone, making use of the supernatural powers that suddenly awakened within her. Her peaceful daily life begins to change dramatically when she meets Elliot and Hannah, a traveling father and daughter.
