Rebirth: The Overbearing Boss’s Sweetheart is Both Delicate and Fierce

Ruan Xing was a high school student who died tragically in her previous life, having wasted nine years obsessively pursuing Huo Jing, a cold and abusive boy, while being manipulated by her stepmother Qiao Li and stepsister Lu Wan. After her death, she drifted as a wandering spirit, witnessing her father's genuine grief and a mysterious young man named Lin Shen avenging her before taking his own life. Reborn back to her senior year of high school, Ruan Xing finds herself at the exact moment Huo Jing smashes a birthday cake into her face at a bar she paid for with her life savings.

Instead of crying or clinging to Huo Jing as she did before, Ruan Xing calmly wipes the cream from her face, demands the 500,000 yuan reimbursement for the party, and walks away without looking back. This sudden change shocks Huo Jing and his friends, who are accustomed to her subservience. Ruan Xing then returns home, where she reconciles with her father, Ruan Ting, realizing how much she had neglected him due to Lu Wan's interference. She confronts Qiao Li and Lu Wan, rejecting their manipulative behavior and asserting her independence, which leaves them confused and angry.

At school, Ruan Xing undergoes a dramatic transformation, removing her heavy, eccentric makeup and dyeing her red hair black. Her natural beauty astonishes her classmates, who had previously mocked her appearance. She befriends Wu Jiali, her deskmate, who had always been kind but distant due to Ruan Xing's obsession with Huo Jing. Ruan Xing dedicates herself to her studies, utilizing her photographic memory to excel academically, surprising her teachers and peers alike. She completely ignores Huo Jing, who becomes increasingly intrigued and irritated by her indifference.

Driven by memories from her past life, Ruan Xing seeks out Lin Shen, the young man in a wheelchair who had loved her from afar. She finds him being brutally beaten by thugs in an alley. Despite her fear, she intervenes, shielding him from their attacks until the police arrive. Lin Shen, initially hostile and self-loathing due to his disability, is confused by her compassion. Ruan Xing ensures he receives medical care and maintains a protective presence in his life, determined to change his tragic fate.

As Ruan Xing distances herself from Huo Jing and Lu Wan, the latter's schemes begin to unravel. Lu Wan loses her privileged status, such as riding in the family car, and faces social embarrassment when her facade of wealth is questioned. Ruan Xing focuses on her new friendships and academic goals, while Lin Shen slowly begins to trust her. The story follows her navigation of high school politics, family dynamics, and her growing bond with Lin Shen, as she resolves to protect those she loves and avoid the mistakes of her past life.
