Edna, a maid, is ordered by her master to conceal her identity and marry the fearsome warrior known as Eli. Soon after their marriage, her 'true identity' comes to light, but Eli dismisses it as no great matter. Yet there is a secret Eli himself does not know… Edna is none other than the hidden heir of the royal family he once destroyed. For eighteen years since birth, she has lived in disguise as a prince.

Despite their complicated circumstances, Edna finds herself drawn to Eli, a man feared across the land as a war-obsessed madman, yet who harbors an unexpected charm. In time, relying on the royal education she received over eighteen years, she pours her strength into cultivating prosperity for Eli’s lands—and transforms into a confident, charismatic lady of the manor.
