In her previous life, Su Nian married into the Chen family and spent three years serving them hand and foot, only to be falsely accused of stealing money by her mother-in-law, Zhao Guifen, forced to drink a folk remedy, and subjected to her husband's cold shoulder at his mother's urging. Chen Ming always had the same answer: "She's my mom. Just let her have her way." Su Nian was on the brink of death from despair when she opened her eyes and found herself back on the day her mother-in-law forced her to drink a "fertility potion."
Reborn, Su Nian is bound to a "Karma Ledger." Every time her mother-in-law does something wicked, the ledger records it automatically and generates evidence such as audio recordings, bank transfers, surveillance footage, and medical records. Her misdeeds can also be exchanged for a lawyer, health checkups, business intelligence, and beauty secrets.
In this life, Su Nian doesn't argue or make a scene. She separates from the family, gets divorced, opens a shop, and builds her career. When her mother-in-law pretends to be ill, she calls 120. When she spreads rumors, Su Nian produces the evidence. When she tries to seize the house, Su Nian sends her a lawyer's letter. When her husband kneels and begs to get back together, Su Nian hands him the divorce papers: "Your mother has had it hard. The two of you can get on with your lives together."
In the end, her wicked mother-in-law is abandoned by everyone, Chen Ming chases after Su Nian only to regret it too late, and Su Nian finds success in both her career and love life. This time, she won't be a pushover for anyone to manipulate. Everyone who owes her will pay her back, one debt at a time.
