Shen Sangning's stepsister, also reborn half a month earlier than Shen Sangning. In her previous life, she orchestrated a chance encounter with Pei Er, swapped wedding attire with Shen Sangning to marry Pei Ruyan instead, but suffered a miserable life as the Heir's wife since he was devoted to work and she bore no children. Now reborn, she happily married Pei Er, believing it would change her fate, but miscalculated since Pei Ruyan's survival prevents Pei Er from inheriting.
