This is the story of Nakazawa Miyu, a girl in 5th grade who lives with her father in a small town bookstore. The problem with this is that this particular bookstore only sells adult books and Miyu’s father uses her as the store mascot in order to draw in customers. Due to that fact Miyu’s mother has long since since left her father and because of this Miyu is trying to find a way of putting her fathers store out of business.
