Aveline Maeve, the illegitimate daughter of Viscount Harry of the Thorne family, exists in a world with where her striking appearance—hair as white as snow and eyes that mirror its colour—only amplifies her isolation. Though she possessess hidden magical abilities, no one knows her gifts, leaving her to navigate life in the shadow of her legitimate siblings and the stricture of ther noble lineage.

Neglected by her family, Aveline often endures the disdain of the household servants, who treat her with rudeness born from her status as an outsider. Despite this, she shared a close bond with her older sister, Emilia Everson, who is just one year older. However, as they mature, their relationship becomes strained. Emilia, with her flowing blonde hair and captivating blue eyes, is the family jewel, admired and sought after by lords from all corners. Her beauty and intelligence set her apart, making her the center of attention and admiration, while Aveline is left in her shadow. Viscount Harry is rarely home, consumed by the demands of his title and often returning late and intoxicated after evenings spent drinking with friends. His absence breeds frustration in his wife, Viscountess Diana, who vents her anger on Aveline, the reminder of her husband's infidelity. Diana's hostility is particularly pointed, as she cannot direct her ire at her own children, and thus Aveline becomed the scapegoat in their household.

Aveline's relationship with her older brother, Henry Oliver, is distant. With his striking green hair an dpiercing yellow eyes, he carries the weight of expectation as the heir to the viscountcy. While he is often busy in his study, amanaging responsibilities that stem from their father's neglect, Aveline finds their bond limited to the formalities of siblinghood. They share little intimacy, further deepening Aveline's sense of isolation.
