I recommend Young Master Gu's Sweetest Wife to you. This book was a novel about a modern wealthy family. The male protagonist, Gu Mo, was a CEO who doted on his wife to no end. The female protagonist, Ke Zi, became the male protagonist's maid for some reason, but the male protagonist's doting on her did not decrease at all. It was as if he could call her over and over again. The plot was very sweet, and the interaction between the male and female leads was also very interesting. There were many small theatres. I believe the plot you mentioned is in this book. I hope you like my recommendation. Muah ~
