I recommend 'Wangye needs treatment, Medical Concubine's arrogance is unusual' to you. This was an ancient romance novel. The male protagonist was physically weak, but his dual personality was a ninth prince, and his other identity was a prince. The female lead had her husband snatched away by her sister and was later forced to marry the paralyzed Third Prince of the Cold King. She also had a medical system. The story was very interesting. I hope you will like this novel.
