Reborn in the 1980s: My Wicked Stepmother Regrets Everything

In her previous life, the heroine depended on her cruel stepmother, was forced to drop out of school, and worked herself to the bone to support her awful family. They arranged for her to marry a man who seemed honest but was actually a gambler and an abuser. After she gave birth, the baby died. The man and his awful relatives took all the money she had worked so hard to earn. In the end, she fell seriously ill, with no one to care for her, and died alone in a cold rental apartment.

Reborn in 198X, before the tragedy unfolds, she has the memories and experience of her previous life and can see through everyone's true nature. She transforms from timid and submissive into someone clearheaded, decisive, strong, and sharp.
