Reborn, I End Up with My Mortal Enemy

In this life, Gu Jiaojiao thought her marriage was harmonious. Her only regret was that she died in the second year of her marriage. Later, she awoke inside a jade pendant and discovered that after just one year of marriage, her husband, Zhao Yilan, had already kept a mistress for a year. Just three days after her death, the mistress was brought into the household. She hadn't died of illness, either: the two of them had poisoned her together.

She also saw Lu Yici, the person she hated most, defy everything to carry her body back to the ancestral grave. She saw him face off against Zhao Yilan in court and tirelessly gather evidence of his crimes, until the emperor ordered the execution of everyone in the Zhao household. On the day of her burial, he even poured himself a cup of poisoned wine, saying he would be buried with the woman in the coffin.
