" I recommend " Transdimensional Books Became the Villain's Favorite " to you. The male protagonist was originally a cold, ruthless, dark, and paranoid boss, but after the female protagonist transmigrated, he completely changed into a different person. Not only did he become gentle and seductive, but he also doted on the female protagonist and showed her affection. The male protagonist is very possessive of the female protagonist, but he despises the female protagonist as a villain. This plot fits the type of novel you're looking for. I hope you like my recommendation.😗
