Chu Wai Tak (Anita Mui) is a natural born introvert, a white collar worker whosuffers from a serious lack of self confidence. Her greatest achievement at work is "using 10% less toilet paper than yesterday" and saving several more cents. King's (Dayo Wong) self confidence is at its peak as he has crowned himself the King of Karaoke. He becomes exhausted if he does not go to the karaoke box and sing for a few days. King loves to gain attention at the company and has indeed brought a lot of energy to a boring company.
