Gaegojin Co., Ltd., has faced the biggest crisis since its inception due to an unexpected fire. Even in a desperate situation when everyone leaves, In-gi, Hojeong, Daeun, Daniel, and Namjin remain until the end and try to revive Gaegojin. They all grow up little by little and come to understand each other as they struggle to cook and eat to save food expenses in the underground office obtained with the help of Hwangdodo.
