Set in an era of three kingdoms—Wei, Wu, and Zhao—power, politics, and betrayal collide. Princess Jiang Taohua of Zhao escapes Empress Lu’s control by marrying into Wei, only to be attacked and falsely accused of scandal. To survive, she becomes concubine to Chancellor Shen Zaiye, a stern official secretly working to reform Wei. Tasked with bringing down the Crown Prince and poisoned by her own court, Jiang and Shen find themselves unwilling allies. As palace intrigues deepen and emotions grow, they form a dangerous pact to expose corruption and shift the power balance—only to find that the real battle for the throne has just begun.
