I recommend the novel,"The World of Medicine: The Tsundere Prince's Concubine," to you. The male protagonist was the crown prince who had been poisoned since he was young. The female protagonist was a female doctor who had transmigrated to become an orphan in the General's Estate who had the same name as her. In the novel, the female protagonist and the male protagonist had an engagement, but the male protagonist was a tsundere prince. The female protagonist used her medical skills and poison skills to help the male protagonist get rid of the poison, step by step. At the same time, there were many grudges between her and the male protagonist. The plot of this novel was full of twists and turns, suspense, and thrills. It was very worth reading. I hope you like this fairy's recommendation. Muah ~😗
