As a child, Natsugami discovered Aki, an older boy, in an abandoned building and Aki became his first love. After going to the building one day to find Aki being assaulted, Natsugami became traumatized, believing it was his fault for telling his friends about Aki. Now in college, Natsugami's film club kouhai Miyoshi has confessed to him. However, unable to reply due to his memories of Aki, Natsugami returns to his hometown and that abandoned building with Miyoshi, in hopes of finding Aki again.
