It's been a few months since Kiyoshi quit his job to fulfill his dream of running a candy store in the outskirts of Tokyo. He wanted to live the rest of his life watching little girls. His plan was a success, with the kids from the nearby school visiting his shop every day and talking with him happily like friends. However, soon after summer vacation started, he noticed one of his usual customers, Chie, stealing some candies. Even though it wasn't much of a loss, he couldn't let it slide. When he questioned her, she said that she'll make up for it by working part-time at his store. Thus begins his summer vacation with small girls.
