You've been a doing nothing ever since graduating from high school. One summer day, your father, the owner of a famous restaurant, "Chanter Chaton," orders you to work there. You comply with his orders. "Chanter Chaton" is famous for its taste, the service, and the waitresses' uniforms. The first floor is a simple cafeteria and the second floor has a very strange feeling to it. This restaurant is so popular; it's hard to approach the girls. One way of approaching the girls is to help them out when they make mistakes.
