[A fiercely protective general disguised as a man × a beautiful concubine-born son disguised as a woman] For certain reasons, Shen Yu, the heroine, was raised as a boy from childhood, while her younger brother Shen Meng was raised as a girl. They were supposed to switch identities when they turned fifteen, but an imperial edict sent Shen Yu to the southern frontier.
By then, it was too late to switch identities, so they had no choice but to keep up the deception.
The emperor then arranged for Shen Yu to marry Gu Yixue, the legitimate daughter of the Gu family. But the person who arrived as the bride was Gu Zeyan, a concubine-born son of the Gu family disguised as a woman.
As Shen Yu and Gu Zeyan spend more time together, they both secretly fall for each other.
Shen Yu shields Gu Zeyan from every storm and ensures he lives a happy life.
Gu Zeyan, meanwhile, washes his hands to cook for Shen Yu and fulfills all his duties as a wife, including carrying a child for ten months.
Beautiful, beautiful, beautiful
