Find a novel with a male protagonist surnamed Gu who is a lawyer, and love after marriage

The male protagonist was Lawyer Gu, and his family was a businessman. The male protagonist's mother and his uncle had a younger sister, and the male protagonist's cousin's wife was called Bai Qiu. The female protagonist and the male protagonist met on a blind date and married. Their lives were peaceful. The female protagonist's mother-in-law was the principal of the school, and the female protagonist was a high school art teacher there. The story began three years after the marriage of the male and female leads. At this time, their love slowly grew. However, the female lead's ex-boyfriend, Zou Jingsheng (who was a neighbor and childhood friend of the female lead), returned to the country to take revenge on the male lead's Gu family. Later, he found out that the female lead's biological father was actually Mr. Fu (the female lead's mother died when the female lead was young). Mr. Fu was Zou Jingsheng's behind-the-scenes partner. Later, because of the female lead, he naturally stopped targeting the Gu family, thus resolving the crisis. The relationship between the male and female protagonists of the novel was full of twists and turns. He remembered that there was once when the female protagonist bought a small suite to stay outside because she misunderstood him.
Zou Jingsheng was the son of a former high-ranking official's mistress. That high-ranking official had deliberately found Zou Jingsheng and treated him well before her accident. He had used Zou Jingsheng's fatherly love for him to make him take revenge on the Gu family when he grew up.
