Shen Zhao was trapped in the deep palace's love and hatred for two lifetimes. In her previous life, as the empress, she blindly trusted the emperor Xiao Yu, stood by while the loyal Gu family was tragically exterminated, watched her beloved Gu Yan suffer a bitter fate, and ultimately died miserably in the cold palace. Reborn three days after the Gu family's raid and confiscation, Shen Zhao resolves to rewrite the tragedy, secretly swapping fabricated evidence and protecting the Gu family's remaining subordinates, vowing to clear the Gu family's grievances. However, a surviving Gu Yan is blinded by hatred, and fueled by Xie Linghui's constant instigations, he concludes that Shen Zhao is a traitor, repeatedly standing against her, casting her into the cold palace, and stripping her of her empress status. In desperation, Shen Zhao fakes her death to escape and completely cuts off all ties. Gu Yan gradually pieces together the entire conspiracy, realizes he wrongfully harmed his true love, and is filled with remorse as he goes to seek redemption.
