Unable to sleep at night, Ganta Nakami is cranky in class and unpopular with his classmates.
He discovers that the school observatory, once used by the now-defunct astronomy club, may be the perfect place for a nap–but he’s not alone. Fellow insomniac Isaki Magari is willing to share the observatory with Nakami, and a friendship between the two begins as they bond over the most unlikely things.
After discovering the source of Magari’s insomnia, Nakami and Magari implement a new nighttime routine, hoping to improve their sleep. With the Perseid meteor shower viewing party and the national photo contest still to come, it’s shaping up to be a very eventful summer for this pair of insomniacs!
