Xie Xu, who falsified her resume and reluctantly became the administrative director of Star Capital, in order to keep her job and pay off her mortgage, carefully followed the rules of survival in the workplace that she summarized after joining the company, but she was accidentally involved in the company's financial mystery. Xie Xu, who had just entered the workplace, repeatedly showed timidity due to his unfamiliar business skills. He also had an intersection with Lin Zhao, the deputy financial manager, and was tested by him everywhere. Later, he discovered anomalies in the company's budget sheet, and learned from his colleagues that Lin Zhao was investigating him, and also implicated Lin Zhao's younger brother Lin Yang, who had been missing for three years. Xie Xu gradually discovered that Li Cheng, the deputy manager of the administrative department, was not only related to Lin Yang's disappearance, but was also suspected of laundering money in conjunction with Zhang Wei, the manager of the financial department. Li Cheng was actually Lin Yang's cousin, and his falsified accounts that year also killed Lin Yang's father. Although Xie Xu was fearful, driven by her conscience, she joined forces with Lin Zhao, Lin Yang, who was investigating the truth incognito, and his former colleague Wang Hao, who had key evidence. After many trials and dangers, he collected ironclad evidence of money laundering by Li Cheng and Zhang Wei, and finally brought the two to justice. Xie Xu also won the company's recognition with this action and resolved the crisis of resume fraud. Not only did she gain a foothold in the workplace, she also developed a different kind of love with Lin Zhao, ushering in new possibilities in the workplace and life.
