Based on the information provided, it is impossible to accurately determine whether the novel "Overbearing Uncle Spoils His Sweet Wife" is a sadistic one or not. It is recommended that you read the novel directly to understand the plot and emotional descriptions. However, I can recommend other novels related to wealthy families and modern romance novels, such as Uncle, Be Good and Pamper Me! Black-bellied CEO: Step by Step Seduction of Marriage, Imperial Uncle's Domineering Pet, etc. They also had similar pet plots and were suitable for readers who liked this type of novel. I hope you like this fairy's recommendation. Muah ~😗
