Year after year, department supervisor Song Chenxi voluntarily works the May Day holiday so her employees can take time off. Instead, a new intern reports her for allegedly pocketing all the triple pay, and even the employees she once helped turn against her and demand compensation. After she is suspended, the intern takes over a project and tries to deceive the client with the previous year's proposal, causing a project worth tens of millions to collapse. Song Chenxi decisively resigns, starts her own business, and wins the client back through her own abilities. The intern, who falsified her academic qualifications, is eventually arrested. After the former boss goes bankrupt, he tries to seek refuge with her, only for her to send him to prison. This is a triumphant comeback after betrayal: kindness must have boundaries, and true ability is what matters.
