Hey, I recommend the novel,"Crazy Woman: Please Have Respect, Your Highness"! The male lead, Song Yunqian, was a slightly sickly prince. The female lead, Wen Yi, was the princess, Yang Luoyi. She also had a kitten that was sometimes fierce and sometimes gentle as a companion. The plot of this novel is complicated. You will like it! I hope you like my recommendation, Mwah ~😗
