The Housekeeper's Son Pretended to Be Me

Is There Any Literature About the Little Housekeeper Going Crazy and Rectifying the Overlord? There Has Been a Shortage of Books Recently.

Want to watch something similar to "It's so cool!" The book "The Little Butler Reorganizes the Overlord's Literature by Going Mad". I don't have too many requirements, just something with a high score, good-looking and sweet, it's really boring to death, I'm running out of books, ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh! ! ! !
