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 don't want to be just
childhood friends anymore.
Ich will nicht mehr nur
die Kindheitsfreundin sein.
Ya no quiero que seamos
solo amigos de la infancia.
Não quero mais ser só amiga de infância.
