Madoka Kawai is an ordinary 14-year-old middle schooler who does not have a boyfriend. Every morning, her osananajimi (childhood friend) Shōta Kaji comes by and wakes her up, yet she never considers him as a love interest. After her classmates learned that the two were not going out, handsome Kaji was soon surrounded by girls, making Kawai nervous for something she had not realized yet.
