Shen Qingci died on his wedding night. A glass of poisoned wine and a word of "substitute" ruined his infatuated love. When she opened her eyes again, she returned to the day she married Xiao Jinyu, the cold king. In her previous life, she thought she was marrying a gentle prince, but she didn't know what kind of sinister soul was hidden under the black python robe.

However, when Xiao Jinyu was on the wedding hall and her fingertips touched the jade pendant in her hand with frost, she was shocked to realize that his memory seemed to be trapped in the fire. Is this wrong marriage a continuation of bad luck or the beginning of the entanglement between two lives?
