At dusk, I don't know how many springs and autumns have passed through the years. In an almost ignored corner of a certain city, there is an unknown and mysterious bookstore. It's unknown because the store has no name, and the books it sells have no titles, and we don't even know the name of the shop owner; it's mysterious because it's been so many generations since this bookstore was located here, as if everyone was born with this bookstore, and the silence of time highlights the mystery of the bookstore...
The boss is a middle-aged man who looks to be 40-50 years old. He wears a pair of semi-gold-rimmed glasses that appear to be of high prescription. There is always a smile on his face. Generally speaking, it is the kind of smile that does not make you disgusted at first glance because of the professional smile, nor does it make you feel shuddering. It feels like the kind of loving smile that an elder treats a junior. This feeling applies to customers of all ages, from elderly people in their twilight years to girls and boys as young as eighteen years old. Oh, I almost forgot, there are some strange rules in this store. Rule 1: Do not sell books to underage customers; Rule 2: Each person is limited to purchasing one book; Rule 3: If you do not have the patience to finish reading, or do not understand or comprehend the content of the book, you must return the book, remember!
