When a major company project is on the verge of collapse, workplace manager He Chuan steps in to save the day by spending 68,000 yuan of his personal savings to hire four people to work overnight. Instead of receiving reimbursement, he is betrayed by the company: most of his expenses cannot be recovered, and he is even demoted and stripped of his bonus. Faced with empty promises from his superior and indifferent colleagues, He Chuan refuses to keep shouldering the company's responsibilities without limits. After resigning and joining a competitor, he firmly establishes professional boundaries and refuses to use his own money to pay for the company's mistakes. He finally regains his professional dignity, but the cost of his past sacrifices remains impossible to erase completely.
