Please recommend a novel about the male protagonist marrying the female protagonist in order to coax his grandmother. The female protagonist's younger brother suffers from leukemia.

The male protagonist's mother hated the female protagonist very much and thought that she had climbed up the social ladder. The male protagonist had never known that the female protagonist's younger brother was sick. Later on, they divorced, and the male protagonist realized that he had fallen in love with her. He often stared at the pocket watch in a daze. The female protagonist planned to auction herself off in order to raise money for her younger brother's surgery fees. The male protagonist saw it and bought it. The female protagonist was also very surprised to meet the male protagonist. In fact, the female protagonist planned to have a fairy dance and even found a neighbor to act. In the end, she was brought home by the male lead.
Later, in order to get the female lead back, the male lead told the female lead that he would pay for his brother's surgery, but he wanted to remarry her. They signed an agreement at the hospital. The female lead was hit by a car to save her mother-in-law. She was found pregnant at the hospital, and the two of them talked things out.
She just forgot the title of the book and hoped that the Almighty could help her.

Answer 1

The female lead, Su Xiaoying, once sold herself to the male lead, An Yiquan, and then disappeared. Ten years later, she returned with her son, who was actually the male lead's child. The female protagonist's younger brother also had leukemia, and the male protagonist often accompanied him. The male protagonist wanted to marry the female protagonist, but he had to coax his grandmother first, so the two pretended to be husband and wife, and the female protagonist's relatives also joined their plan. As a result, they slowly came together. I hope you like my recommendation. Muah ~
