Short on cash, Kohinata Shuu casually pops into a bar in a corner of the city called "Care Snack Versailles." Inside the bar, there are nursing care products lined up, and on the counter shelves are rows of IV bottles. Each bottle has a customer's name written on it and is kept on standby. Most of the customers are elderly people who require care. However, as soon as they step into the bar, they regain their youth and shine. They become incredibly energetic, sing cheerfully, drink happily, and start dancing lightly.
