The Correct Method of Love Is Not in a Book or Blueprint

Izumi Noda, a librarian who prefers being surrounded by books rather than being in contact with people, meets Latin Yoneya Nell, who aims to become an architect with a joint party taken by Kumiko. She was puzzled by Nell, who visits the library every day from the next day, but she was timid about love for some reason. She is attracted, but she knows that Nell approached her as a game among friends.
