Xia Duoduo (Wang Ziwen) is an intern clerk at Qunxing Supermarket. She has a high IQ and performs well at work, but because of her extremely low EQ, she offends her boss and has no hope of promotion. The supermarket is facing bankruptcy due to poor management. Xia Duoduo, the store manager Wang Shoushi (Huang Meng) and the intern store manager Zheng Mo (Huang Xuan) work together to make plans for the future of the supermarket. Sisi (Yin Yezi) is Xia Duoduo's best friend. She mistakenly thinks that Wang Shoushi is a rich second-generation, but she makes a fuss. Xia Duoduo finally looks forward to the promotion, but who knows that the open and secret struggles that follow make her feel exhausted. At the same time, Zheng Mo, who is attracted by Duoduo's innocence and kindness, pursues the former passionately, and the opponent he has to face is his half-brother Geng Zihang (Huang Jue).
