Trapped in a rural arranged marriage to a mentally challenged man, Shu Wanyi rewrites her destiny using future knowledge from a past life. By strategically winning over her adoptive parents—unlike her previous explosive confrontations—she earns a triumphant return to the Shu estate. But her biological brother's hostility and spoiled sister Shu Yuqing's starvation protest force her to "sacrifice" by moving to a hotel. There, she engineers a crisis-meets-rescue encounter with Gu Nanfeng, whose fashion empire teeters on scandal. Her timely intervention sparks a partnership that will redefine both their legacies.
