In the seventeenth year of the Republic of China, mist and rain lingered in the south of the Yangtze River, which could not wash away the troubled times. Five years ago, a deliberate arson attack destroyed the entire Shen family. Beiyang warlord Lu Chengyu forged evidence to blame the Gu family, creating a bloody feud across the two clans and breaking up a pair of young lovers.
Shen Qingyan, a gentle and gentle young man in the past, returned from a bloodbath full of murderous ferocity and became a feared Jiangnan warlord. Burdened with the wronged souls of a whole family, he pretended to be ruthless and vowed to take revenge on the Gu family, but he hid all his tenderness and weakness in Gu Wanci, the legitimate daughter of the Gu family. Everyone in the world scolded him for being indifferent to grudges and being paranoid and cruel. No one knew that he used hatred as a shield just to protect her in the troubled times.
Gu Wanci is the transparent white moonlight raised by the misty rain in the south of the Yangtze River. She has waited for five years and been innocent. She has seen through his forbearance and suffering, and has been trapped in the cage of love and hate. The two reunited in the misty rain, were attracted by suspicion, and entangled in the chess game of power.
