Insomniacs After School

君は放課後インソムニア

Kimi wa Houkago Insomnia

Ganta Nakami is a high school boy in the coastal city of Nanao in Ishikawa. Most nights he barely sleeps. By day he is moody and does not get along with the other students. His school has an old observatory that nobody uses anymore. Ganta sneaks in hoping for a quiet nap. Isaki Magari is already there. She is a lively girl who has been hiding the fact that she cannot sleep either. When the school nurse catches them they bring the dormant astronomy club back to life so the room can stay theirs. Insomniacs After School is a quiet romance about two tired teens who understand each other. Night skies, star photography and small-town scenery fill its pages. It suits readers who like slow and gentle love stories.
