Zhen Huan was reborn and returned to the eve of the wedding ceremony, bringing with her all the memories of her previous life from Wan Guiren to the Queen Mother - the pain of losing a child, the estrangement between sisters, the betrayal of lovers, and the strife in the palace. Her only obsession in this life is to avoid all calculations and substitutions, protect her family and those who treat her sincerely, break free from the shackles of the palace, and live a life that belongs to "Zhen Huan" rather than "Pure Yuan Stand-in" or "Emperor's Concubine". Each chapter is interspersed with the tragic memories of the previous life and the choices of avoiding pitfalls in this life. The psychological activities are throughout, in line with the delicate and profound writing style of the original work, gradually advancing the plot and showing Zhen Huan's growth and transformation.
