Duke’s daughter Lize has been dumped five times, earning her the cruel reputation of an unmarriageable "spinster." Her final match in the noble marriage market is Roy, a famously wicked, ill-mannered prince who holds the record for breaking ten previous engagements himself! Expecting a typical romance, Lize is instead handed a strictly business transaction. Roy bluntly tells her to write out her expectations in a formal contract, demanding not just a trophy wife on paper but a hyper-competent executive right-hand woman to help him run state affairs. As two pragmatic, high-capability cynics who scoff at romantic notions, their purely professional contract marriage quickly evolves into a high-stakes workplace dynamic packed with sharp banter, mutual respect, and unexpected chemistry.
