I Become A Burdensome Child After Transmigrating Novel

On her eighteenth birthday, Su Jiu dies and transmigrates into a novel about tragic love, reborn as an adorable four-year-old. She discovers she's destined to become the novel's villainous second female lead, and her father is a lazy celebrity. Worried about her father's career, Su Jiu takes charge, pushing him to maintain his image, prepare for work, and seek a stepmother. Her efforts transform him from a hated figure into the nation's most popular celebrity, accumulating vast wealth. As the sole heir, Su Jiu inherits billions and anticipates a life of leisure. However, her plans are disrupted when the novel's menacing villain, instead of the main female lead, begins to court her. Despite her past childhood kindness being the only interaction, the villain's intense devotion and possessiveness become apparent. He, who was once perceived as an emotionless business mogul, now pursues her relentlessly. Years later, the now powerful villain becomes her father's boss. The doting father, realizing the danger his daughter is in, warns her about the villain. The villain, however, issues an ultimatum: marry him and receive his devotion, or face his wrath, which includes blacklisting her father and destroying his career.
