At forty-nine, Xingfu was a veteran taxi driver and an award-winning employee at his cab company. He had never made a mistake before, but when he first met Lin Yaxuan, a beautiful university student, he mistakenly gave the 100,000 yuan she had lost to the accountant at Mengya Garment Factory. A month later, the accountant told Xingfu that the money wasn't theirs. Finding Lin Yaxuan became the most important thing in Xingfu's life. One night, while working, he spotted her outside a nightclub but couldn't manage to speak to her. All he could do was wait there for her to appear again.
When Xingfu drove Lin Yaxuan home from the nightclub, he finally got to know her. It turned out she was working her way through school to pay for her mother's medical treatment. At the nightclub, Lin had met Liu Jiang, an accounting manager at a major company. Liu had made money on the stock market, then lost it, and had been forced to use company funds through his position. His conscience made him feel sympathy for Lin, and his own loneliness made it impossible for him to leave the beautiful woman alone.
Xingfu went from taking an interest in Lin Yaxuan, to sympathizing with her, to falling in love with her.
Just as Lin Yaxuan and Xingfu were at the height of their love, she discovered that Wang Pingping, her best friend and roommate, was Xingfu's biological daughter. Wang Pingping had always tried to set Lin Yaxuan up with her cousin, Zhang Li. Zhang Li followed Lin and discovered her relationship with Xingfu. In an instant, all their lives were changed. Xingfu's wife took her own life. Wang Pingping, believing her mother had died because of Lin, her best friend, fell into depression. Although Xingfu and Lin Yaxuan did everything they could to care for her, she lost control and followed her mother in death. Xingfu developed nervous exhaustion and had to buy a car and stay at home. Lin Yaxuan was the only one by his side. Zhang Li truly loved Lin Yaxuan. In front of all their relatives, he did everything he could to defend the dignity of Xingfu and Lin Yaxuan's sincere love.
After Lin Yaxuan's mother died, the two lovers could no longer bear the pain of missing their departed family. Lin Yaxuan and Xingfu agreed to leave this world together, leaving behind a letter of farewell for Zhang Li, the only relative who understood and accepted them.
