I recommend Xu Fanhua's Request to Marry a Princess Consort to you. The male and female protagonists of this novel were also separated because of a misunderstanding. The female protagonist transmigrated to become a princess, but she was not loved. The male protagonist was a prince in a wheelchair. The relationship between the two was full of twists and turns, full of pain and obsession, but in the end, they were able to be together again. Moreover, this novel had palace fights and house fights. In addition, the female protagonist was a master psychologist. The whole story was very heart-wrenching and would make you unable to stop. I hope you like my recommendation. Muah ~
