My Billionaire Queen Sister

Billionaire Chloe slips into her brother Leo's wedding incognito, wanting to share his big day without fanfare. Her haughty sister-in-law-to-be, Victoria, takes her for a mistress and publicly tears into her. When Leo discovers what really happened, he cancels the ceremony right away to shield Chloe. Stung and craving revenge, Victoria teams up with Leo's illegitimate half-brother and their icy biological father, plotting to take over his tech company using Wall Street money.
