The aim of Manager Nashizaki Tatsuya, who heads the Pianissimo Club, is to construct Japan's largest hostess club, a destination that would appeal to men of all nationalities and ages. An ultimate contest for the finest hostess with a prize of 100 million yen is expected to take place alongside the mammoth club. However, Aya, a reluctant freshman, does not appreciate the concept of being a hostess. Her parents' enormous financial obligation compels her to become one. A friend pushes her to join Pianissimo, and Aya reluctantly begins her journey as a hostess.
