Two of the world's top espionage masters play each other's good-for-nothing son-in-law and cute wife in an ordinary family. Neither of them knows the other's true identity. The male protagonist protects the city in the open (the god of war), while the female protagonist controls the overall situation in the dark (the hacker/king of intelligence). When the two parties discovered each other's identities, the relationship instantly changed from "you look down on me and I look down on you" to "the person I want to get rid of the most is actually sleeping next to me." A high-intelligence, high-intensity, high-reversal daily spy battle between husband and wife.
