Pegasus Books, a long-established book store faces ever more difficult financial challenges with the rise of online bookstores, but our two heroines, having been saved by books, try to fight for it! One of them is Aki, age 23, a staff member at Pegasus Books. The second one is Riko, age 40, the assistant manager there. Two working women clash with each other over their generation gap and differing circumstances. However, by facing their work and romantic problems with determination and overcoming them, they each realize what they are lacking in or what they have forgotten, and grow together.
