In his past life, Gu Yuan spent ten years of financial resources sponsoring the campus belle Lin Su, only to be cut off by her single phrase of a clean break, ultimately dying in destitution. Reborn back to the eve of the fallout, he immediately freezes all of Lin Su's funds and residence to cut his losses in time. After losing her affluent life, Lin Su endlessly entangles him, while her suitor Zhao Lei maliciously frames Xu Zhiyi, the Xu family heiress whom Gu Yuan has gotten to know, out of jealousy. Xu Zhiyi steps in to investigate Zhao's misdeeds, ruining his reputation. Losing her support and seeing her life plummet, Lin Su is filled with remorse and desperately begs to get back together, all of which Gu Yuan rejects. Gu Yuan and the perceptive, loyal Xu Zhiyi gradually develop mutual affection, joining hands to build a blissful family and completely parting ways with the unbearable past.
