I'm looking for the title of a manwha/manga, I can't really remember which was it, but it is about a librarian with inky. He was formerly a teacher but goes to a different world to be a librarian and he recommends different books to his customer and they become op. It has also a lot of misunderstandings. It has a great story but I can't remember the title ╥﹏╥
did loosing my mind
