A moving adventure under the starry sky – two teenagers battling insomnia! Ganta is extremely unpopular among his classmates due to his constantly irritable nature. However, no one suspects that his bad mood is due to a sleep disorder. Night after night, he lies wide awake in his bed, unable to sleep. But everything changes when he stumbles upon the abandoned observatory while preparing for the school festival. The tranquility and seclusion make the place an ideal sleeping spot – if only his classmate Isaki Magari wasn’t already sleeping there!

To avoid losing their new sleeping spot, they start an astronomy club and discover new hobbies along the way. Amidst constellations, photography, and new friendships, the two grow closer.
