Shen Zhaoning is a princess of noble birth who conceals her identity for love and marries the impoverished scholar Gu Yanzhou under the guise of being a merchant's daughter. For ten years, she devotes herself wholeheartedly to supporting him, paving the way and building bridges until she raises Gu Yanzhou from a failed examination candidate to a sixth-rank official. But once he gains power, he not only curries favor with the Prime Minister's daughter but also forges private letters, intending to drive Shen Zhaoning out of the household on the false charge of infidelity. He has calculated everything, yet he does not know that Shen Zhaoning has never been a merchant's daughter who can be manipulated at will, but a princess who defended her country by defeating an army of one hundred thousand enemies! Since you dare to slander me and divorce me, then I will make you suffer utter disgrace!
