Let me recommend an ancient romance novel called "The Beautiful Servant: The Rise of the Eastern Palace". The story was about the female protagonist who had transmigrated to another world and became a royal lady in the palace. She was doted on by the princes. In the palace full of conspiracies and schemes, she was shocked step by step and climbed to the top of the clouds. Although it's slightly torturous, the female lead isn't stupid, so it should meet your needs. I hope you like my recommendation, Mwah ~๐
