I recommend a novel to you called "Concubine's Concubine: The Poison King's Defiant Medical Concubine". It tells the story of a timid female protagonist who became the Defiant Medical Concubine of a prince with a different surname after being poisoned by her fiancé. The relationship between the two is also very exciting. I hope you like my recommendation. Muah ~
