My Delicate Wife

Anna Cole is married to the Crown Prince, and nobody in the capital knows it. He looks mild and is sharp-tongued and devious underneath. They work well together: she settles things by force, he finishes them with words. Anna leads the martial arts alliance. She returns to the capital to find her birth family, and her parents trap her into taking her sister's place in a marriage to a man with an intellectual disability. Everyone treats her as a country girl who can be pushed around, unaware that she is a fighter no one there can handle. The two of them play at being harmless. They take money off the wealthy families of the capital and lead their opponents around.
