Commandery Princess Gu Shengyin of Qinghe fell to a rival she should never have lost to—a transmigrated woman who stole everything from her. Only in death did the truth crystallize: she was merely supporting cast in someone else's ascension story, destined to be trampled beneath an outsider's feet. Reborn in a void of pure white, Gu Shengyin downloads the System's revelation. The playing field has shifted. Supporting characters demand redemption. Cannon fodder crave vengeance. Forgotten extras hunger for recognition. And she—the so-called female lead—stands as their ultimate target. Cold determination flickers behind her gaze. Her smile cuts like frost. "We shall discover who truly deserves to fall beneath fate's heel, and who will claim final victory." Let those scheming underlings, those expendable pawns yearning to obliterate the female lead and seize supremacy, contemplate their chosen ends. A passionate 1V1 romance wrapped in intrigue and retribution.
