Singoseojeom is a used bookstore in front of Duksung Women's University in Dobong-gu, Seoul, selling everything from old books to comics and academic texts. Books fill multiple floors, and visitors can order capsule coffee at the first-floor cafe and read. An outdoor table on the roof looks out toward Bukhansan, and each floor has a reading area. When the shelves are packed and the store is crowded, it is hard to check book information in the aisles.
