Last summer.
Ruriiro was approached by his twin sister "Soubi," inviting him to a movie shoot. Before he could refuse, he found himself filming with two of his classmates whom his sister had gathered.
"Because Soubi's special."
Ruriiro has always stayed on the sidelines in the shadow of his talented younger sister. However, as he spent time with his shooting buddies "Minamo" and "Nagi," his transparent life began to change. For the first time, experiencing emotions, and numerous struggles.

And it was that summer――.
――Soubi disappeared.
