Su Ying was forced to marry Xie Wang, the Lord of the Netherworld, but found out that she was not a princess, but a "living mirror prison" used to replace the ancient evil mirror and seal the ghost king. On their wedding night, the ghostly figure in the mirror smiled at her; since then, every reflected object has become a window for her to glimpse bloody memories. She is not only a prison for him, but also gradually eroded by his broken and violent origin. When cracks appear in the seal, the sins of the past are intertwined with the horror of reality. She must find the truth before she is completely "contaminated" into another monster - about the old mirror, the tragic death of the woman in red, and the truth about this eternal imprisonment in the name of marriage.
