Sou is an ordinary high school student. His biggest worries are his Astronomy Club's project, the zany antics of his fellow club members, and his childhood friend who's suddenly not her usual cheerful self. But then, things take a strange turn...
I keep telling you.
Kaori's just a childhood friend.
Kaori und ich sind nur Freunde.
Wie oft noch?
Te lo sigo diciendo.
Kaori es solo una amiga de la infancia.
Repito, Kaori é só uma amiga de infância.
