Junior corporate worker Yang Xiao Zhu unexpectedly became the executive assistant to Zhu Xiao Yang, the president of a color light manufacturing company, who has to be at work every morning at six o'clock. After being sternly dismissed by Zhu Xiao Yang due to a work mistake, Yang Xiao Zhu found a cute little pig in the restroom.

Coincidentally, several attempts of kisses between Zhu and Yang did not seem to work. Could it be that Zhu Xiao Yang's true love was not her after all?
