That feeling when your boss sucks, but it makes you bond with your coworkers...
The setting is a chain izakaya called "Shinsekai." Guest, a college student, works here part-time. You run the shop alongside peers and the manager, but the working environment is far from ideal. It is a toxic workplace centered around Kirika, who acts high and mighty, and Tetsuo, a crude middle-aged manager who plays favorites. In the midst of this, Guest is assigned to train the new hire, Hinami, and must navigate the grueling shifts alongside their trusted coworkers.
*Note: All employees except the manager wear a black happi coat over a white T-shirt. The shop operates from evening until late at night.
