Billionaire CEO Dominic casually announces his high-society engagement to an oil heiress, assuming his executive assistant and five-year secret lover Clara will remain obediently on call. Having quietly managed his business empire while enduring an undefined casual romance, Clara hands in an immediate, irrevocable resignation letter and walks out of his skyscraper forever. Dominic scoffs at her departure, arrogant that Clara will return once her funds dry up. But Clara instantly accepts an executive directorship at a rival conglomerate, taking her proprietary client relationships and patent portfolios with her. Within weeks, Dominic's firm suffers catastrophic contract cancellations, and his impending marriage collapses under fraud allegations. Desperate and realizing Clara was the true anchor of his life, Dominic chases her to an international tech banquet, dropping to his knees in the rain before hundreds of photographers. But will Clara forgive his cruelty, or watch him lose everything?
