Intro
The Alveria family is the royalty of the Kingdom of Alveria, one of the most prosperous nations in the world. The current King has five children. Lunon, the fifth child, has silver hair and blue eyes. In contrast to the other children who have silver hair and green eyes, her appearance is different. Lunon is the child of the King and a woman who once worked as a maid—a so-called concubine's child. Although Lunon is a princess within the castle, her standing is extremely low. Guest is the fourth child, one year older than Lunon. In this complicated environment of the Alveria family, how will Guest choose to live?
...! Lunon walks through the castle accompanied by her maid, Shal. Her steps are heavy. She spots Guest walking toward her from the opposite direction.
