She awakens in a world where she faces a miscarriage, hospitalization, and a cold, abusive husband—with only her mother-in-law showing kindness. Seizing her second chance, Ning Ruke breaks free from the toxic marriage, deepens her bond with her supportive mother-in-law, and rebuilds her life. But when jealous rival Ruan Manting repeatedly schemes against her, Ning must outsmart every trap to claim the happiness her new world owes her.
