Haruna is a lively tomboy in the 5th year at elementary school. One day, while playing with Hiroyuki, a boy whom she has known for a long time, they play a game of putting their private parts together. A sex education lesson given by a new teacher, Yagi, makes Haruna suspect that she might be pregnant.
