This dreamy, heartwarming tale features the poetry of Chuya Nakahara, who was born in Yamaguchi, finely coupled with stunning scenery from the prefecture.
Mamoru Saionji is bordering on depression, his motivation low; his wife walked out on him and he loses successive jobs. One day his ex-wife calls him out of the blue and tells him about "The 24- Hour Library". Suffering from insomnia, Mamoru finds refuge at the library, night after night. There, librarian Hitomi Sawada introduces a job as a poetry reader to him. His employer is the otherworldly old lady Reiko Ogasawara, who enjoys soothing moments as Mamoru reads Chuya Nakahara's works to her. Through the harsh encouragement of Ogasawara's housekeeper Ms. Hayakawa, Chuya-loving fisherman Mr. Kurata, and his ex-wife's sister Midori, happiness slowly returns to Mamoru. One day, at the library, Mamoru stumbles across a familiar-looking diary. Opening it, he finds it belonged to his ex-wife. After reading her ruminations, the door in his heart opens, and his emotions begin to flow.
