Synopsis
Summer vacation in the second year of high school.

I experienced one summer's memory.

A little mysterious girl with a citrus scent. She came to my forgiveness with unconventional behavior.

Jumping over even time, my future ── to stop my dying life.

This is a mundane story that happened somewhere in the world. It may be commonplace, but it's also an important and unforgettable memory for me and her.

It's a story of "overlapping summer" that I and she experienced somewhere in the world.
