To avenge her older sister, the female lead, Ye Wanqing, assumes the identity of her twin, Ye Zhangge, who died on the battlefield. In a desperate gamble that would leave both sides badly wounded, she marries Zhao Lingyun, a frail and beautiful young man from the family she seeks revenge on. But the seemingly sickly beauty has also been impersonated by the Zhao family. The sickly, obsessive secret guard is real: Chu Nanchen, raised by the Zhao family from childhood, marries into the general’s household, never expecting to give his whole heart away.
