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...
If only I could just go floating up
and get sucked into the starry sky.

y ser absorbido por el cielo estrellado.
Se pudesse flutuar
e ser sugado para o céu estrelado.
