In her previous life, Nangong Shu had a bumpy marriage. She was deeply in love with the prince, had a sweetheart, married a sworn brother, and found a househusband...
She obviously did nothing wrong, but she was always treated as a femme fatale, was scummed in various ways, and was eventually killed.
After her death, the prince ascended the throne and proclaimed himself emperor, his bamboo horse entered the cabinet to worship the prime minister, his sworn brother supported the army as a general, and even his husband became the regent of the court, and launched a vigorous pursuit of her cousin.
Nangong Shu's mentality collapsed. After being reborn, she just wanted to send the scumbag men to their funerals and open a harem to experience the joy of changing grooms every night.
But she didn't know that all four of her ex-husbands were reborn, and they looked at her in strange ways.
