I recommend a novel to you, Young Grandmaster. The main character of the novel, Lin Feng, was the disciple of a cultivation grandmaster who had returned to the secular world to become a live-in son-in-law. In the novel, Lin Feng's wife was also the campus belle and the chairman of the company, which was similar to the situation described in the question. In the novel, Lin Feng was also humiliated and despised by his wife, but he didn't retreat. Instead, he used his wisdom and strength to gradually win his wife's respect and love. I hope you like my recommendation.😗
