Kim Hang Ah is a legendary special forces instructor from North Korea—tough, disciplined, and unmatched in combat. Despite her strength and fierce reputation, she longs for something simple: to fall in love and get married.

Lee Jae Ha, the charming and sharp-tongued prince of South Korea’s royal family, seems like the perfect catch. But behind the polished exterior, he's materialistic, carefree, and uninterested in politics—until a sudden tragedy thrusts him onto the throne.

In a bold move toward peace, North and South Korea agree to a political engagement between Hang Ah and Jae Ha. Thrust into an unexpected union, the two must overcome cultural divides, personal clashes, and political intrigue.

Can love blossom between a no-nonsense soldier and a reluctant king—for the future of Korea?
