According to the information provided, it was not certain which book it was, but the modern aristocratic family novel " Capturing the Cute Wife: A Date with Mr. CEO " also had a female lead named Su Nuannuan, a male lead surnamed Zhong, and Su Nuannuan's sister named Su Meili. I recommend this novel to you. The plot is funny and interesting. The interaction between the male and female protagonists is also very interesting. I hope you like my recommendation.
