In her previous life, Su Wenyue was driven by vanity. She abandoned her husband and child, ultimately meeting a tragic end when she was falsely accused and killed by the mistress of the house.

Her three-month-old unborn child perished with her. Meanwhile, the humble man she had looked down upon seized the opportunity in the chaotic times. He steadily climbed the ranks to become a high-ranking and powerful prime minister in the great kingdom.

Su Wenyue died in remorse. But upon awakening, she found herself back at the moment when she had just married into the Han family.
