A 65-year-old woman is reborn as an 18-year-old, just as her stepmother is about to sell her to a scumbag who beat his previous wife to death.
In her last life, she endured everything, then died on New Year's Eve with nobody to claim her body.
This time, she strikes back hard:
Her stepmother tries to sell her? She exposes her in public, splits from the family, and cuts ties.
The scumbag tries to deceive her? She schemes to make him marry her stepsister, so they can torment each other for the rest of their lives.
Her own son is unfilial? She doesn't give birth to him this time, leaving him to kneel and beg her to acknowledge him.
Her biological father abandoned her? He is exonerated and returns to claim her, but she asks, "Who are you?"
She gets into university, opens a pharmaceutical factory, becomes the richest person around, and raises children who all thrive.
The simpleton who treated her well in her last life becomes a devoted husband in this one.
In the end, everyone kneels and begs for forgiveness, but she forgives not one of them.
She has everything she should have. She wants nothing she shouldn't.
