During the anniversary year, the late emperor passed away, the young emperor ascended the throne, and the queen mother listened to the government behind the curtain. The regent Xiao Heng held military power and formed a confrontation between the two powers.
Shen Qingci, the adopted daughter of the Shen family, and her sister Shen Qingge are twin sisters with the same appearance but different destinies. The elder sister was engaged to the regent, but died unexpectedly on the eve of the wedding. In order to protect their interests, the Shen family pushed Shen Qingci, who had a similar appearance, into the sedan chair to marry in her elder sister's stead.
On their wedding night, Shen Qingci was trembling with fear, but found that Xiao Heng had already figured out her identity as a stand-in. He looked at her with cold eyes, but was unconsciously attracted to her; she knew that he was a substitute, but she felt the long-lost warmth in him. The two tested each other, fell into each other's traps, and got deeper and deeper on the edge of truth and lies.
However, there is a deeper secret hidden behind this relationship - Shen Qingci's memory was sealed, and she forgot her life-saving grace to Xiao Heng when she was young, and she also forgot the truth she discovered that could overturn the world. Sister Shen Qingge did not really die, but faked her death to secretly guard deeper secrets.
When the mystery of her life experience was peeled away, Shen Qingci was actually the princess of the previous dynasty and the daughter of the Queen Mother. She and Xiao Heng were actually aunts and nephews in name only. When love meets ethics, when revenge intertwines love and hate, they get closer to each other and hurt each other, sinking deeper and deeper into the whirlpool of truth and lies.
"I pretended to be her, and you fell in love with me. Is it a blessing or a misfortune?"
