In an era where possessing others is a national trend, Aillet, a young girl in a heartwarming parenting story, wishes for nothing more than love and affection. However, fate has other plans as she finds herself in "Seguhoe," a notorious reincarnation story known for its frustrating plot and high difficulty. As an extra character, the young daughter of a servant in a soon-to-be-ruined Count's family, Aillet's survival is far from guaranteed. Despite her circumstances, she finds unexpected comfort in a kind and caring older brother and father, and even makes a close friend who shares her interests. With the support of the strangely helpful Gods from the Possession Management Bureau, Aillet's life takes an unexpected turn for the better. She even discovers a 'Possession Life Insurance' package that allows for rapid growth, enabling her to actively change the original story. As she strives to improve the frustrating plot, she encounters Tesillid, the male lead, who is still somewhat immature. Why doesn't he act differently around her? This is a long romance fantasy novel by Irinbi.
