I recommend the following three villain novels to you: " I Don't Want to Be a Villain "," On the Rebirth of the Protagonist: How He Fallen ", and " The Sick Villain Steals the Male Lead's Script ". These novels all had plots similar to the protagonist transmigrating into the novel and becoming the villain. Moreover, there were stories of the villain fighting against the protagonist. It was worth reading. I hope you like my recommendation.😗
