At some point in time, somewhere, there is a place called “Kawazuya”.
Won't you come enjoy the beauty of the everyday life of the shop owner, a frog with a smiling face and large body, and Yuu, a high school girl and part-timer?

In early summer, 2nd year of high school, Koguma's mom suddenly leaves, leaving only a note that says "Bye." She is alone, having no parents, no friends, no hobbies. She silently reflects, "I don't have anything." But a chance encounter results in her buying a Honda Super Cub with a disturbing history, and a new life suddenly blossoms open.
