In her past life, Shen Tingwan was meticulously plotted against by her mother and younger sister Shen Zhirou, had her engagement swapped, was reduced to a pawn in a family political marriage, tragically lost her child, and was buried in a sea of flames. Awakening with a rebirth across lifetimes, she resolves to break free from the shackles of family affection and reject that marriage full of conspiracies. Unexpectedly, she learns that Lu Chenyuan, who should have perished at the border guards, has also awakened with memories of two lifetimes. The two meet once again in Shuobei, joining hands to uncover all conspiracies, reckon with all villains, cross the boundaries of life and death, and rush toward the two-lifetime reunion that belongs to them.
