Signals like the moon, streetlights like stars. The camera warmly captures the winter night roads, and the director's eye is also that of a director looking at two people who are more than friends but less than lovers. When Sakai chooses what is most important to him without hesitation, i.e. when he accepts the responsibility of loving her, the period in which she "had chosen" to leave him gives the story a deeper depth. A film that uses unrealistic motifs but depicts the birth of happiness in a sufficiently realistic way.

Kumi seems to have what seems to be a psychic ability herself to hear the voices of certain people even when they are far away, and carries out experiments to try to find her friends. Then two men, Satsuki and Minoru, arrive. Kumi, Satsuki, and Minoru struggle with their own lives while enjoying their secrets. The people they meet are also living their lives. The three meet again at the seaside late at night, and realize that they have become each other's dearest friends, and that their relationship is about to end.
