After three years of marriage, Ruan Qingyi regarded her stepbrother Wen Yuzhou as her closest relative, but regarded her husband Yu Yanshen as an outsider. On Wen Yuzhou's birthday, she gave him a sports car; on Yu Yanshen's birthday, she drank with her stepbrother. On the day her child died, she slapped her husband in public: "Murderer!" At the funeral, she waved her palm again. Until she discovered her stepbrother's encrypted hard drive - a ten-year diary with heartbreaking words. From wedding anniversaries to prenatal check-up reports, from sowing discord to deliberately delaying medical treatment, every step is a carefully designed trap. She knelt in front of Yu Yanshen and handed over the evidence, but he only said: "What I hate is not that you were cheated, but that you never believed in me." On the day the court decreed the divorce, he left without looking back. And she finally learned what it means to chase her husband in the crematorium.
