😋I recommend the following books to you: "The Useless Crown Princess Consort Is Happy","Guards, The Crown Prince Is Happy", and "The Crown Princess Consort Is Leveling Up Again". They were all novels about time travel and ancient romance. They all had elements such as favoritism, 1v1, purity of body and mind, and black-bellied. They had similar plots and topics as "Reporting to the Prince Regent's Crown Prince to Take a Concubine." I also recommend a new book,"The Emperor's Strong Pet: The Poison Concubine's Too Arrogant", to you. It's also a novel about transmigration. It has a powerful female protagonist and a favorite male protagonist. It also has similar elements to other books. I hope you like my recommendation and feel free to ask me any questions. The above is my personal recommendation. I sincerely hope you like it ~
