When college student Fumiya visits the Friday Bookshop as a last-ditch effort to find a book for his ill father, he is disappointed in its ordinary appearance despite whispers of its peculiar charm. But he soon discovers that it not only includes a cafe where the food menu changes daily on the chef's whim but also a vast underground vault lined with bookshelves, lovingly converted from an old abandoned subway platform. The bookshop, run by a quirky trio who have been close friends since high school, quickly becomes Fumiya's favourite place-so much so that he begins to work there part-time. Fumiya, who was never really a reader, learns to embrace the joy of reading, and that books can be a means to connect with other people and navigate the twists and turns of life. Through colourful interactions with the zany shop owners and their visitors, as well as mouthwatering dishes inspired by the books the owners recommend, it's impossible not to fall in love with the seemingly ordinary yet enchanting little bookstore in the subway station in Kanto.
