Three years ago, she was forced by a colleague to take the blame for leaking the company's confidential information. Once a project supervisor, she was reduced to working as a food delivery driver and became a single mother raising her sick son, Doudou, alone. Her ex-husband looked down on her, former colleagues humiliated her, and malicious complaints threatened to take away her livelihood, but she gritted her teeth and endured it all. When she was at her lowest, a mysterious Mr. Jiang anonymously paid her medical and rehabilitation bills and repeatedly came to her rescue. When her former enemy forged evidence to have her thrown in prison, she finally uncovered a crucial piece of evidence she had forgotten for three years and publicly revealed the truth at the shareholders' annual meeting. The man who had silently protected her turned out to be the very man she had rescued from a car accident on a rainy night three years earlier.
