University student Ryouta Wakamizu, who is the middle of job-hunting, gets caught up in a sudden gang dispute. Ryouta's life is saved by Ryuichi Yanagiba, the boss of Yanagiba-gumi, and Ryouta somehow ends up harboring Ryuichi in his own home. Ignoring Ryouta who wants him to leave immediately, Ryuichi uses the leftover food in the fridge and starts to prepare a meal without asking. However, the meal is surprisingly delicious despite the leftovers that did not seem possible to combine. This is the beginning of a bizarre communal life connected by meals for a gangster and a university student.
