Adal is a transmigrator into the world of Boen.
    Not just any transmigrator, but a man who has the ability to perfectly remember everything he has ever read.
    In this new world, he inherits a library, and fills the shelves with books he had rewritten himself, using the memory of books he had read on earth.
    Most particularly, the genre of Smut.
    After introducing this new genre to the world of Boen, Adal earns himself reputation that he would have never dreamed on earth.
    And with help from the unique LustLord class that he manages to awaken, Adal decides that not only will be become the greatest Librarian of all time in this new world, but he will also fuck as many beauties as he can along the way.
