Seven years ago, Lin Shuhe donated part of her liver to save Fu Jingchuan, but Xu Manning drove her away by making the surgical expenses a condition. Shuhe gave birth to their daughter, Tangtang, alone, and her health deteriorated until she was confined to a wheelchair. Seven years later, she survives by collecting discarded bottles with her daughter when an unexpected collision with a luxury car belonging to the Fu family brings her face-to-face with Fu Jingchuan again. He resents her for supposedly abandoning him for wealth, while she silently bears his accusations. Only when Tangtang is diagnosed with leukemia does Fu Jingchuan discover that the child is his daughter. He finally uncovers the truth: Shuhe was the one who donated her liver, while Xu Manning falsely claimed the credit for saving his life. Overcome with remorse, he devotes himself to treating his daughter and helping Shuhe recover. As Shuhe gradually rises from her wheelchair and rebuilds her life with her own hands, she is finally moved by his awkward yet unwavering sincerity.
