I can't remember the name of the male lead in this novel. The female lead is called Gu Qian 'qian, and there's another character called Lu Zhanbei and Lu Zhandong.

The title of the novel was " A Substitute Wife ", a modern romance novel about wealthy families. The male lead, Lu Zhanxun, was the heir to the Lu family, while the female lead, Gu Qianqian, had an average IQ and low EQ, but she had a cute little face. Lu Zhanxun had lost his self-control the moment he saw her. However, Gu Qianqian had a grudge against her younger brother, so she made Lu Zhanxun promise that she would leave as soon as her younger sister returned.
