Let me recommend you a few novels with a normal male lead and a sick female lead (or harem): 1. "Wear It Quickly: Your Male Lead Has Fallen Again": The female lead is insidious and cunning, while the male lead is perverted and sickly. The main theme is sweet and pampered, and the little sadistic seasoning is used to counter the sweet and pampered dog food. 2. "Quickly Wear the Villain's Sweet Wife": The male lead is a refined scum, while the female lead is unpredictable. The plot is interesting. 3. "Quickly Wear Big Boss: Sick Villain, She's Scumbag and Flirtatious": The female protagonist is serious about her career, while the male protagonist is a loyal dog. The plot is strong and cool. I hope you like my recommendation, Mwah ~π
