Shen Qingci died on her wedding night, her deep devotion destroyed by a cup of poisoned wine and the word "stand-in." When she opened her eyes again, she was back on the day she married Prince Han, Xiao Jinyu. In her previous life, she thought she was marrying a gentle, refined prince, never knowing what kind of sinister soul hid beneath his dark ceremonial robes. This time, with an ancestral jade pendant that can reveal cause and effect in her hand, she vows to avoid the bloody conspiracy. But when Xiao Jinyu touches the pendant in her hand during the wedding ceremony, frost gathering at his fingertips, she realizes that his memories, too, may be trapped in that great fire. Is this ill-fated marriage the continuation of a doomed bond, or the beginning of a tangled relationship spanning two lives?
