I recommend the novels "The Rise of the Wealthy Class, the Return of the Resplendent Queen" and "Master Quan's Secret Wife". "Rise of the Wealthy Class, Return of the Resplendent Queen" was a novel about a modern aristocratic family. The female protagonist was Resplendent, the third-ranked assassin of Hell, while the male protagonist was the overlord of the business world in S City. Although the female protagonist came to assassinate the male protagonist under the order of her superiors, after a mistake, their lives entered the same track. The male protagonist was extremely doting, the female protagonist was strong and extraordinary, and the male and female protagonist were both physically and mentally clean. "Master Quan's Secret Wife" was another modern aristocratic novel. The female protagonist was extremely beautiful, but she was hit by a car accident and became a fool. The male protagonist was the invincible Master Quan. The two of them were arranged by fate. The male protagonist was extremely doting, and the female protagonist was also very strong. It was a hot-blooded battle between the strong woman and the strong man, a collision of beliefs. Both novels are very suitable for the needs of a brother-sister relationship. I hope you like this fairy's recommendation. Muah ~
