Akimoto Yae is a cheerful - and sometimes exceedingly loud - girl who secretly always watches her sempai Ayase, who rides the same train as her. For some reason, Ayase always sits in the same seat, holding the same book, opened at the same page. His hands never try to turn to the next page.One day, Ayase accidentally drops the book, which comes as a chance for Akimoto to talk to him. Much to her surprise, he isn't interested in having the book returned, and gives it to her.As Akimoto tries to overcome her mild aversion for printed texts - which causes her to sleep if she doesn't read the lines aloud - and read the book, she hopes to get closer to Ayase, who has reasons of his own to be aloof.
