As a princess, Qingyang defies her parents and insists on marrying Li Heng.
On their wedding night, her husband and cousin join forces to drug her, and she loses her virtue to her dissolute younger brother-in-law.
Ashamed that she has lost her virtue, Qingyang feels she has wronged her husband. After the wedding, she works tirelessly to support her husband's family, helping them all rise to prominence.
Within a year, her father dies and her mother hangs herself. Before Qingyang can recover from her grief, Li Heng brings her pregnant cousin before her, forces her to drink a potion that will make her infertile, and tries to demote her from wife to concubine.
Qingyang makes a scene, but Li Heng claims she has gone mad. He plans to send her to an enemy's bed, using her beauty to further his career and wringing every last bit of value from her.
Unable to bear the humiliation, Qingyang hangs herself at the Li family's gates and becomes a vengeful spirit.
…
For six years as a ghost, Qingyang watches her longtime nemesis, the dissolute younger brother-in-law she never thought much of, Li Jiming, become a renowned general and personally kill the people she hates most.
Reborn, Qingyang decides to make the best of things and join forces with him for revenge!
…
Li Jiming's boastful confession:
As a dissolute wastrel hated by everyone in the capital, I had the nerve to secretly love a girl for years. Everyone thought we couldn't stand each other.
Then she was about to marry her childhood sweetheart, and I drowned my sorrows in drink.
Then my reckless cousin drugged my wine to insult her, and the two of us had a less-than-perfect wedding night.
Then she decided to switch brides and marry me, and even wanted to help me rise to the top.
Then I became a celebrated general, and a little bundle of joy joined our family.
Li Jiming put his hands on his hips and sighed. How could a man be this lucky?
You can also take a look, there is nothing terrible. Being rich and powerful means being wanton. There is no suspense about rebirth and revenge. Happy ending.
