The legitimate daughter of a general's household suffered betrayal by her fiancé and stepsister, dying a tragic death only to be reborn as Qin Wan, the princess consort of her sworn enemy prince. While the original host was timid and humble, she possessed peerless medical skills, beauty, and talent. At the start of their newlywed life, she and Prince Feng Ling—who held heavy military power, cold and suspicious—were on guard against each other, looking at each other with mutual disdain. In the process of investigating conspiracies side by side, the prince fell in love first, helping her secretly time and again. Leveraging his power for revenge, Qin Wan slowly let down her guard through successive perils as tender affection gradually sprouted. Together, the two tore apart their enemies' disguises and shattered layer upon layer of conspiracy.
