Princes, Take Your Shots

Two modern best friends transmigrate into a pair of twin sisters sent by an enemy nation for marriage alliances, secretly serving as spies. They marry the cold-faced War God Prince Rui (the eldest brother) and the charming, scheming Prince Jing (the second brother). Both brothers are wary of this union, but they never expect the 'high-level spy' in the eldest's eyes to be a pure bookworm obsessed with knowledge and clueless about romance or intrigue, while the 'innocent love-struck girl' the second brother wants to control is actually a master of human nature who turns the tables on him. A sweet battle of mistaken identities begins.
