The male lead was a rich playboy, but after meeting the female lead, he became different.

I recommend the book,"The Perfect Son-in-law." When the male protagonist was dealing with the female protagonist's problems, he gradually realized the side of the world that ordinary people did not know. He became stronger, defeated his enemies, and took revenge. Step by step, he reached the peak. During this process, the male lead of "The Perfect Son-in-law" was also convinced by the female lead's charisma. He became more and more powerful and fought alongside the female lead. I hope you like my recommendation, Mwah ~😗
