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 mouth-watering dishes inspired by the books they recommend, it's impossible not to fall in love with the seemingly ordinary yet enchanting little bookstore in the subway station in Kanto.
