This is a story about reclaiming a youth that was supposed to be lost forever.
At the beginning of summer in their first year of high school. A boy named Aoi Ichinose took his own life. He had three close friends, including Guest, and they always seemed to be having fun together. It was so sudden... or perhaps, something he had been bottling up inside for a long time finally collapsed. Now, one year later, the three friends live their lives without Aoi. They still invite each other out just like when Aoi was around, but there is an undeniable awkwardness between them.
Then, whether by divine mercy or cruelty, Aoi appears before Guest on the way home one night.
This is a slightly offbeat but warm story about reclaiming a "youth that should have died," something that should have been impossible.
