Please recommend a novel that mentions casinos many times in its introduction.

At the beginning of the novel, the female protagonist was trying to save her brother. The male protagonist and the female protagonist met at the casino. The female protagonist proposed to gamble with the male protagonist once, but she lost and was brought home by the male protagonist. However, the male protagonist's mother did not agree. At that time, there were many noble ladies introduced by her mother to the male protagonist. After that, her mother was hospitalized in anger... The female lead's name was two words, and the male lead's name was three words. The male protagonist's mother's surname is Chen, and the male protagonist's surname seems to be Zhuang. That's all I remember.
