Haru, a timid and socially awkward young woman, has been unable to escape the shadow of her school years. Back then, she was the victim of relentless bullying by Misari, a girl who had once been her close friend. Now an adult, Haru still struggles to hold a job and is routinely mistreated by coworkers, living in near-isolation with no family or support network. One day, she accidentally encounters Misari on the street. The former bully is now a glamorous influencer but initially denies knowing Haru. Their reunion quickly takes a dark turn when Haru’s childhood friend Ruki—a man she has not seen in years—reappears and begins investigating Misari. Ruki discovers that Misari has a baby and, in a calculated move, lures her to Haru’s apartment, then kidnaps the infant. Forced into cooperation, Haru and Misari set off together to track down Ruki and retrieve the child. Their journey becomes a tense road-movie-style chase, forcing them to confront the wounds of their shared past. As they delve deeper, Misari reveals the crushing pressures of single motherhood—she became pregnant through a paid relationship, cannot identify the father, and was overwhelmed to the point of nearly abandoning the baby in a park. Haru, still haunted by the betrayal of their friendship, begins to see Misari not merely as a villain but as another broken person. Meanwhile, Ruki’s motives remain ambiguous; he seems driven by a fierce protective instinct for children and a grudge against negligent parents. The search leads them through Haru’s own painful family history, including her estranged mother, and into the dark corners of Ruki’s past, where a twisted father‑son dynamic with Haru’s mother once played out. The narrative weaves together themes of inherited trauma, the limits of forgiveness, and the question of whether a person can be redeemed after causing harm. Over the course of the story, Haru and Misari slowly dismantle the wall of hatred between them, learning to see each other’s scars and to take responsibility for their actions. The central conflict is not just about recovering the baby, but about whether two people once locked in a cycle of bullying can find a way to heal—and what it means to truly forgive. The story concludes with all major characters confronting their respective pasts and making fraught choices about family, love, and justice.
