Ye Xiaotong (played by Ye Yuqing) is a cashier. Her husband Abo abandoned her and ran away from home. The innocent Ye Xiaotong fell into a scam again. When she was isolated and helpless, it was Liu Zhengwen (played by Liang Jiahui), a policeman living in the same building, who lent her a hand. With the help of Liu Zhengwen, Ye Xiaotong got a job as a car salesman. However, Ye Xiaotong knew nothing about cars, so Liu Zhengwen taught her bit by bit from scratch. In the process, the spark of love collided between the two. Just as their feelings were gradually heating up, Abo returned to Ye Xiaotong's side. This time, Ye Xiaotong was no longer weak. She decisively rejected Abo's request for peace and decided to find a new life for herself. However, Ye Xiaotong was always hesitant to accept a new relationship. Coincidentally, so was Liu Zhengwen.
