The story begins with Morino Yuri, a woman who has finally achieved her financial goal, trembling with joy as she checks her bank account. For years, she has been a "shachiku" (workaholic) in a black company, enduring excessive overtime and holidays. Discovering the concept of FIRE (Financial Independence, Retire Early) on a train, she was inspired to save and invest aggressively, even starting a YouTube channel to share her frugal lifestyle and investment strategies. Despite sacrificing her social life and appearance, she relentlessly pursued her goal. Just as she was about to submit her resignation, she collapses from exhaustion, her consciousness fading.
Yuri awakens to find herself in a child's body, addressed as "Lily." She realizes she has been reborn into a new life. Her mother, Alma, and older brother, Cain, are concerned. Lily, now five years old, remembers her past life as Yuri and the circumstances of her death. She learns she is part of a family that runs a small diner. Her head injury, sustained from falling while chasing Cain into the forest, triggered the return of her past life memories. Cain, who found her unconscious, had lied to their parents about the cause of her fall to avoid getting into trouble. Lily, overwhelmed by her memories, briefly loses consciousness again.
Upon waking the next morning, Lily's memories have integrated, and she now possesses Yuri's personality and experiences. She observes her new world, which resembles medieval Europe, with its distinct architecture and customs. She notes the low living standards but is relieved by the presence of a flush toilet, albeit one with a peculiar gel-like substance. Realizing she has been reincarnated into another world, Lily, who was an avid reader of reincarnation novels, is initially dismayed to find herself a commoner without any special powers or cheats. However, she quickly resolves to achieve FIRE in this new life.
Lily's family runs a diner, with her father, Eugen, as the cook and her mother, Alma, as the server. Cain, her two-year-older brother, helps with chores. Lily, despite her recent injury, is expected to contribute to the household. She observes her father's imposing demeanor and her mother's tireless work ethic. Cain is particularly caring towards Lily, doting on her and ensuring her well-being. Lily's initial attempts to understand her family's finances are met with her mother's explanation that they are not wealthy and prioritize helping the community by keeping prices low, a philosophy Lily finds reminiscent of her past life's family business and a significant obstacle to her FIRE goals.
A major conflict arises when Cain expresses his desire to attend knight school, a dream his father, Eugen, vehemently opposes due to the cost and danger. This argument leads to Cain running away to the forest, where Lily, despite her own limitations, follows him. In the forest, Cain reveals he possesses magic, a rare trait for commoners, and that knights require magic to use magical swords. He laments his family's lack of funds for knight school. Lily, drawing on her past life's determination, promises to help him achieve his dream by creating a financial plan, which surprises Cain. During this conversation, Lily experiences a surge of heat and what she suspects is magic, causing her to collapse.
Lily recovers and, with her family's support, begins attending a church-run daycare where she can learn to read and write. This is a crucial step for her FIRE plan, as literacy will enable her to manage finances. She also learns that Cain has magic and that the world has elements of fantasy, including monsters and magical barriers. The family agrees to try and save money for Cain's knight school, a significant shift in their mindset. However, a devastating revelation follows: Lily is diagnosed with "Rainbow Sickness," a terminal illness that affects young children before their baptism, meaning she has limited time left. This news deeply impacts the family, especially Cain, who feels guilt over his past harsh words to Lily. Despite the grim prognosis, the family resolves to make Lily's remaining time happy and fulfill her wishes, including her desire to save money and Cain's dream of becoming a knight.
