I'm not sure specifically as I haven't read this exact novel. But generally, a title like this might be about someone trying to bribe a billionaire and then the billionaire seeking revenge. Maybe it involves business deals gone wrong or personal vendettas in the high - society world of the super - rich.
I don't know the exact main characters as I haven't read it. But it would likely include the billionaire, who is the target of the bribery and the one seeking revenge. And there must be the character or characters who attempt the bribery.
The theme of revenge is central. The billionaire, having been hurt or wronged, sets out on a path of vengeance. He may use blackmail to expose secrets or force the antagonist into a difficult situation. As for the romance, it can be a complication or a solution. Sometimes, the love interest tries to stop the revenge, leading to conflict. Other times, they are caught up in the revenge plot themselves, which adds to the drama.
One story could be about a wife who discovers her husband's infidelity. Instead of immediately confronting him, she quietly takes control of their finances. She moves money into accounts he doesn't know about and then when the time is right, she files for divorce and leaves him with very little. Another story might involve a wife whose husband has been verbally abusing her for years. She starts documenting all the incidents secretly. Then she uses this evidence to expose him to his family and friends, causing him to lose their respect.
One popular one could be 'The Ruthless Billionaire's Revenge'. In this type of novel, the billionaire often uses his wealth and power to seek revenge on someone who has wronged him in the past, and blackmail might be involved in the complex relationship with the female lead.
