Plot

Maevika (Mae/Maple), the only heiress of Superior Group, one of the country's leading department store conglomerates, is a confident young woman until she loses a joint school project competition to Aiwarin (Ai), the only heiress of Orianna Group, one of the largest hotel empires in the nation.⁴ Years later, as leaders of their respective companies, they compete head-to-head for the Greater Duty Free concession, a multi-billion project.⁴

Circumstances force the two into close proximity, turning their rivalry into an uneasy alliance.
