High school student Jinta (Nijiro Murakami) is a hikikomori and lives in Chichibu, Saitama Prefecture, Japan. One summer day, when Jinta is absorbed in a video game, a girl suddenly appears in front of him. The girl is Jinta’s childhood friend Meiko (Minami Hamabe), but it seems impossible because Meiko edited on a summer day. Meiko wears the same white dress when she is edited, but she looks a little taller. She tells Jinta that she has a wish and that she is a ghost, but Meiko can’t remember what her wish was.
