One day, Miwa's little brother came home late from playing by the Tama
River with one of his friends and an adult man. He convinced Miwa to
come meet the man, claiming he looked like Johnny Depp. Miwa and her
friend Aya come to meet him after school and discover that was a total
lie.
However, Miwa finds herself drawn to the goofy young man,
whose name is Haruo. To Aya's annoyance, Miwa develops a major crush on
him and talks about him constantly. But could anything come of this
crush, since Miwa is a first year high school student and Haruo is an
adult? Miwa starts to get to know Haruo, meeting him day after day,
there by the Tama River.
