The same day Lily loses her boyfriend of eight years and her job, a runaway five-year-old crying by the river asks her to be his new mom. She brings him home on impulse—only to learn she's "kidnapped" the heir to the city's biggest fortune. The cold, devastating billionaire who storms in doesn't press charges. Instead he offers a contract: $25,000 a month to become his son's live-in tutor. The lonely boy sees his dead mother in Lily; the icy CEO slowly melts. Just as love begins to bloom, his scheming fiancée—the fake heiress—poisons the child and frames her. Kitchen cameras expose the truth, the villain is banished... and the accidental "kidnapper" ends up with the billionaire husband, the son who chose her, and the whole world she never expected.
