Xu Qinghe, a trainee saleswoman at a jewelry counter, has gone two consecutive weeks without making a sale. Her customers are stolen, she is burdened with miscellaneous tasks, and she faces the threat of losing her job. Ostracized in the workplace, she unexpectedly serves a customer named Tang Guifen, who is concealing her identity, and earns an opportunity to serve as acting supervisor. Refusing to rely on anyone's protection, she faces her colleagues' doubts head-on and proves her abilities through professional service and a competitive assessment. While defending her professional dignity, she also finds a love built on mutual respect and equality.
