Quan Minghe, the Qian Yuan Emperor of the Qian Dynasty, ascended the throne at thirteen and unified the realm by eighteen. Known for his cold, calculating nature and dedication to governance, he maintains strict control over his inner palace and political rivals. During a secret visit to the Temple of Sacred Sound, he survives an assassination attempt by remnants of the former Jinlin Kingdom, only to discover he has been poisoned with an aphrodisiac on the assassin's blade. His subordinate Zhao Cong is ordered to find a woman to counteract the drug's effects.
Meanwhile, Shen Yuling, the sixteen-year-old daughter of Grand Protector Shen Yuan, visits the temple at night to pray before her arranged marriage to Feng Moheng, the Prince of Lingyang. She makes five wishes for a handsome husband, eternal beauty, and lasting love. Zhao Cong's men intercept her and bring her to Quan Minghe. However, Quan Minghe discovers another woman had been sent as a trap and instead uses Shen Yuling, who is unconscious from a sleep-inducing strike. The encounter leaves Shen Yuling physically violated but outwardly compliant. Unbeknownst to Quan Minghe, Shen Yuling is not the original owner of this body—she is a modern actress who transmigrated into this world after agreeing to a mission from the Galaxy System.
Shen Yuling had previously entered a white void space where she met the original Shen Yuling, a woman who had lived two rebirths attempting to avenge her clan's extermination. In her first life, the original Shen Yuling married Feng Moheng but failed to prevent the Shen family's downfall. In her second life, she entered the inner palace to gain the Emperor's protection but suffered a miscarriage and remained powerless. With only one rebirth left, she begged the system to find someone capable of completing her revenge. The system selected Shen Yuling, the modern actress, offering three wishes in exchange for inhabiting the original Shen Yuling's body from birth and experiencing all her memories and emotions.
Shen Yuling accepts the mission, understanding she must navigate a world where the Emperor is the predetermined great male protagonist whose storyline cannot be altered, while her targets include Liu Jingyi, a transmigrated woman who stole the original female lead's fate; Liu Shihan, the Crown Prince's mother who holds absolute inner palace power; and Feng Moheng, the man who abandoned the original Shen Yuling. She must also contend with the Emperor's possessive nature after their encounter.
After the temple incident, Quan Minghe becomes obsessed with finding the woman who escaped him. He commissions a portrait and orders Zhao Cong to locate her, threatening severe punishment if he fails. When Zhao Cong discovers Shen Yuling is the Grand Protector's daughter—already betrothed to the Prince of Lingyang by imperial decree—Quan Minghe's reaction shifts from murderous intent to calculated restraint. He recognizes that Shen Yuan's military power in the northwest makes direct confrontation unwise. Instead, he orders surveillance on the Princess Consort, wanting to know everything about her.
Shen Yuling's wedding to Feng Moheng proceeds as planned. On their wedding night, she confronts Feng Moheng, who openly declares he will not love her or consummate the marriage due to his devotion to Liu Jingyi. Shen Yuling, however, refuses to be a passive victim. She proposes a partnership: they will pretend to be affectionate in front of his mother, the Grand Princess, to protect Liu Jingyi from further persecution while maintaining their respective positions. To create the appearance of consummation for the morning inspection, she bites his finger and uses his blood on a handkerchief, demonstrating her cunning and willingness to manipulate circumstances to her advantage.
The story establishes a complex web of political intrigue, revenge, and power dynamics. Shen Yuling must balance her mission to avenge the original host with her own survival in a dangerous court where the Emperor watches her every move, her husband resents her, and her enemies hold significant influence. Her modern perspective and acting skills become her primary tools as she navigates this world where fate, rebellion, and desire intersect.
