The fake princess was reborn as a real concubine

Jiang Yingwan, a young woman of exceptional beauty, dies a horrific death by strangulation with a white silk sash after her false identity as a princess is exposed. In her previous life, she had been mistaken for the lost Princess Lingyi and brought into the imperial palace, only to be abandoned by her adoptive mother, Lady Wang Zhaoyi, and ignored by the Emperor when the real princess, her younger sister Jiang Yinghan, returned. Consumed by regret and terror, she dies alone in a stormy night. However, she awakens to find herself back in the palace on March 14th, three months before her identity was originally exposed. She realizes she has been reborn and is determined to survive this second chance, avoiding the tragic fate that befell her.

Understanding that she cannot simply reveal her true identity without facing execution for confusing the royal bloodline, Jiang Yingwan decides to bide her time. She knows that Lady Wang Zhaoyi, who holds no favor with the Emperor and has no biological children, is using her to regain imperial attention. Jiang Yingwan plays along, presenting herself as a filial and timid daughter to win the Emperor's pity and protection. She recalls that in her past life, the Emperor had shown initial kindness but withdrew due to her fearfulness and Wang Zhaoyi's complaints. Determined to change this dynamic, she actively seeks the Emperor's company, serving him tea and displaying her skills, which gradually softens his attitude toward her.

Her strategy begins to yield results as the Emperor grows fond of her gentle and dependent nature. He views her as a delicate flower that requires his protection, a sentiment reinforced when she tearfully confesses her fears to him after being bullied by the Fourth Princess, Jiaru. The Emperor, feeling guilty for neglecting his lost daughter, becomes increasingly protective, punishing the Fourth Princess for her rudeness and granting Jiang Yingwan special favors. Meanwhile, Jiang Yingwan navigates court politics with caution, maintaining a facade of ignorance and submissiveness while internally plotting her escape plan. She intends to live peacefully for three months until the real princess's return, at which point she hopes to reveal the truth and retire to her hometown.

As her birthday approaches, the Emperor insists on hosting a grand celebration, further entangling Jiang Yingwan in palace life. She forms a tentative bond with the Crown Prince, Li Mu, who offers her brotherly support and protection, particularly against the malicious Second Prince, Li Qian, who had bullied her in her past life. Despite her efforts to maintain distance, the Emperor's growing affection for her makes it difficult to execute her plan to leave. She realizes that her survival depends on continuing to play the role of the favored, timid princess, even as she feels the weight of her deception and the looming threat of the truth coming to light.

The narrative highlights the complex power dynamics within the imperial court, where Jiang Yingwan must balance the ambitions of various concubines, including the favored Yang Jieyu and the powerful Concubine De, while relying on the Emperor's favor for protection. Her rebirth has given her the knowledge to navigate these dangers, but it has also placed her in a precarious position where every interaction is a calculated move to preserve her life. As the birthday banquet draws near, Jiang Yingwan faces the challenge of maintaining her carefully constructed persona while preparing for the inevitable confrontation with her sister and the Emperor.
