Ishidaira is a delinquent who visited the library for the first time since elementary school. He discovered that he still hadn't returned a book he borrowed 10 years ago. He ended up having to work part-time at the library to pay for it. This is the beginning of a manga that makes you want to go to the library after you read it.
