Maevika, the only heiress of Superior Group—one of the country's leading department store conglomerates—is a confident and self-assured young woman. But her confidence crumbles the day she loses to Aywarin, the only heiress of Orianna Group, one of the largest hotel empires in the nation, during a joint school project competition. Years pass, this time as leaders of their respective empires—competing head-to-head for the high-stakes Greater Duty-Free concession, a multi-billion project.
