Hayakawa Shuichiro (U ไฝๅ Shin), a high school student, had an empty feeling as if he had a gaping hole in his heart. We have friends who are the center of the class, and we have partners to play with. But from the moment I gave up the music I loved, it felt like I wasn't breathing.
One morning, Hayakawa felt an intense suffocation in the classroom and ran to the roof of the school building to escape. On the rooftop where no one has to worry about the eyes of others, Hayakawa finally regained himself.
Unconsciously, sing. The next moment, I heard the sound of shuttering.
The camera was held by his classmate Ryohei Konno (Hirano Koshu). "You looked good, so I filmed it."
Hayakawa is captivated by Konno's straight gaze for some reason.
Since that day, the two have become "rooftop friends" who speak only on the roof.
Konno, who was obsessed with his favorite camera, was the type that Hayakawa's friends didn't have. Hayakawa seems to have feelings similar to longing for Konno, but at the same time have a strong sense of inferiority. One day after school, after an incident in an unpopular science preparation room, Hayakawa realizes that his feelings for Konno are not just "friendship" but a special feeling...
