Yes, I recommend a novel to you. It's called "Master Leng's Favorite: The Sweet Wife Is Too Difficult to Chase After". It's also a modern romance novel about wealthy families. Although the plot is different, there are also elements of the male protagonist being cold and domineering, and the female protagonist not admitting defeat. You can take a look at this book. I hope you like my recommendation. Muah ~
Anna Delvey is a woman who made headlines for passing herself off as a wealthy German heiress in New York's high - society. She managed to infiltrate elite social and financial circles, conning banks, hotels, and wealthy individuals. She used her false identity to live a lavish lifestyle, staying in luxury hotels and dining at expensive restaurants without actually having the funds to support it.
Well, it's a bit hard to say for sure. She might be in a place where she hopes to start anew and avoid all the media attention. Maybe she's moved to a quiet town or is trying to blend in somewhere anonymous.
