Natsuki Hayashi is a 26-year-old office worker who leaves home at 8:00 a.m. and returns home at 6:00 p.m. everyday. She is usually dressed in a suit, but when she comes home, it is her castle. She lives in a 2DK apartment complex, surrounded by the sundries she has collected since her school days. Her daily routine is to cook dinner while listening to music. All recipes are in her head. The events of the day, things that interest her, and nostalgic memories. Whatever pops into her head, she cooks it rhythmically. Muttering to herself, she lets the music take over and today, too, a new recipe is born.
