Stupid Grandma's Revenge

For 10 years, Eleanor hid her billionaire status, playing the humble maid to protect her son's fragile ego. But when her spoiled granddaughter returns from Paris and insults her in French—calling her 'stupid' while her son laughs—Eleanor is done playing nice. Revealing her flawless French, she walks out. In one night, she freezes their black cards, evicts them from her penthouse, and cancels the brat's scholarship. They thought she was a helpless old woman. Now, they'll lose everything.
