One day, in an alternate world where all life had vanished, leaving behind only a single girl.

Insects, fish, birds, beasts, monsters, and even humans had all disappeared without exception.

All that remained were plants.

A boy who stumbled into this alternate world met the girl.

Yet, despite their inability to communicate through words, the two nonetheless strive to understand each other and slowly form a deep connection. And then...

This is a novella-length story.
