In her previous life, Lu Zhaoning, a daughter of the Lu family born to a concubine, was framed by her legitimate elder sister, Lu Mingyan. Reborn overnight, she returns to the night when her fate took a dramatic turn. Concealing her sharp edge, she carefully schemes at every step. With the Empress Dowager's support and her children to secure her position, she fights back amid the undercurrents, settles old scores with her own hands, eliminates Lu Mingyan, and drives Prince Duan to his death. Once a concubine-born daughter whom everyone could trample underfoot, she ultimately takes control of the entire princely household, clears her name, and achieves her long-awaited revenge.
