Mewika, the sole heiress to Superior Group—one of the country's leading department store conglomerates—is a self-assured young woman. However, her confidence crumbles the day she loses a joint school project competition to Aiwarin, the sole heiress to Orianna Group, one of the nation's largest hotel empires. Years later, now leading their respective empires, they go head-to-head for the high-stakes Greater Duty-Free concession—a multi-million dollar project. Circumstances force them together, transforming their rivalry into an uneasy alliance. For May, this proximity becomes a strategy to uncover Ai's secrets and win the bid. But for Ai, it is an opportunity to get closer to the woman she has secretly loved since the day they first met.
