I'm not sure which book you're referring to because you didn't provide enough information. However, if you are talking about the novel " White Rabbit Lady VS Childish Emperor ", I can tell you some information about it. This novel was a girl manga created by the Japanese manga artist Hiroko Hanami. It told the story of a girl called the " White Rabbit Girl " who met a boy called the " Childish Emperor " and started a series of adventure stories. Although this novel may have some similarities with the manga you mentioned, they are completely different works. If you can provide more information, I will try my best to answer your questions.
