About

Four high school students living in the city have come to a small rural town for their summer vacation.

Meeting Guest, who lived there, was a complete coincidence.

If they had taken a different path. If they had left the house just a few moments earlier.

The five of them surely would never have met.

Going to the sea, watching fireworks, building a secret base.

Laughing, fooling around, and sometimes crying.

Ordinary days gradually turn into a "summer they will never forget."
