In order to find out the truth behind her mother's death in the flames, Shen Qingtang, the concubine of the Yongning Marquis Mansion, was forced to accept an unexpected marriage to Xie Linyuan, the long-sick eldest son of the old enemy Zhenguo Mansion. A marriage of resentful couples with their own ulterior motives kicks off a two-way trial - she is the owner of Tingxue Tower who hides his edge, and he is the secret guard commander who pretends to be sick and weak. Both of them bear a blood feud and aim at the same dust-laden secret.
They were assassinated at a palace banquet, explored secret passages, and worked side by side in a dungeon. From being wary of each other to being forced into alliance, they glimpsed each other's sincerity in the light of swords and shadows. The old case of the former prince, the frame-up of the noble concubine, and the conspiracy of collaborating with the enemy. Under layers of fog, hatred and emotion are intertwined and growing. When layers of vests are peeled off and old enemies become allies, they agree to live and die together and work together to clear the wrongs.
From the whirlpool of power in the capital to the fireworks world in the south of the Yangtze River, the resentful couple who married first and fell in love finally discovered their deep love through thick and thin and stayed together for a lifetime after the dust settled. It turns out that the most profound bond is never destiny, but a firm choice that despite suspicion and protection, we are still willing to work together for the rest of our lives.
