I recommend the modern romance novel,"The CEO's Little Wife." The female protagonist and the male protagonist were the neighbors of the school. They were brought together by their mother to get married, but the female protagonist was very resistant to the male protagonist at first and even thought that he was retarded. In order to pursue the female lead, the male lead even offered very attractive conditions, such as buying a luxury car for the female lead and so on. In a series of daily bickering, the two gradually fell in love. I hope you like my recommendation. Muah ~
