Murasaki Wakako is a 26-year-old OL that loves nothing more than delicious food and drink. Wakako's favorite thing to do for relaxation is to go off by herself after work and go to various places to eat and drink, even if she's never been there before. The moment Wakako is able to taste the pairing between the food she wants to eat and the perfect accompanying drink, the happy sound of "Pshuuu" leaves her lips. Now, then. Where shall we drink tonight?
