An Ran (played by Sun Ya) and her husband Ouyang Yifeng (played by An Zehao) have been married for many years. They raise their lovely daughter Mengmeng (played by Gao Xinyu). Although their life is plain, it is full of happiness. An Ran's only regret is that her family's economic situation is not as good as the upper class but better than the lower class. However, Ouyang Yifeng has always been indifferent to fame and fortune and is unwilling to work hard for a better life. The little disappointment is buried in An Ran's heart and gradually takes root. By chance, An Ran met her high school classmate Bao Lina (played by Wang Ou) and found that Bao Lina was carrying a famous bag, wearing a famous brand, driving a luxury car, and living a very luxurious life. Under Bao Lina's brainwashing, An Ran decided to become a pharmaceutical representative like her, but An Ran soon found that if she wanted to do this job well, she would not be able to do it without some "unusual" means.
