A "Refresh Man" is an employee who has no passion for their job. They don't care about their underachieving reputation, as long as they get paid for showing up to work they are fine. They report to work on time only to do personal stuff during working hours and count down to the end of the work day to leave on time.

In high school Zhong Yu Tang (Joanne Tseng) was the overachiever with a bright future ahead of her while Ji Wen Kai (Aaron Yan) was the underachiever with the worst grades out of the entire class. Ten years later the tables have turned when Wen Kai becomes the new CEO of the cosmetic company Yu Tang works for. Yu Tang becomes Wen Kai's personal secretary but on her first full day working for him she realizes she is not up to par being an executive secretary when she fails miserably at every given task. Wen Kai has to call in his longtime assistant Miao Ai Sha (Lene Lai) to help him translate during a business meeting with a foreign account, and because Ai Sha is the only one that can communicate with the foreign account person and read the foreign documents, she gets hired at the cosmetic company.
