In Nanao City, Ishikawa Prefecture, first-year high school student Ganta Nakami was troubled by insomnia. One day, he meets Isaki Magari, a classmate, in the unused school observatory. Surprisingly, Isaki also suffers from insomnia just like Ganta.

Though they barely speak to each other in class, the two become connected through their shared secret of insomnia and start napping together in the observatory during break time and after school.

However, their unauthorized use of the observatory is discovered, putting it at risk of being off-limits. To protect the place where Isaki finds solace, Ganta decides to revive the dormant Astronomy Club.
