In her previous life, Xie Qingwan was supplanted by her younger half-sister and forced to give up her betrothal to the heir of the marquis's estate. She was made to marry a poor scholar instead.
Unexpectedly, on the very day of her wedding, the heir was ordered to war. He returned with injuries to his lower body that left him impotent.
Her half-sister couldn't bear the loneliness and took a lover. She was confined in the Buddhist hall, where she wasted away and died.
The poor scholar passed the imperial exams with flying colors and rose to the position of Grand Secretary, doting on his wife as if she were his life.
Xie Qingwan went from rags to riches, becoming the highborn mistress of a household whom every woman in the capital envied.
But only she knew all the hardships and torment she had endured.
The poor scholar had only ever used her. Once she had served her purpose, he sent her off with a cup of poisoned wine.
When she opened her eyes again, Xie Qingwan and her half-sister had both been reborn on their wedding day.
Her half-sister wept and begged to marry the poor scholar.
Xie Qingwan smiled. This time, she would marry into the marquis's household and protect the heir herself!
