Jiang Rongyin is the Ninth Princess of the Dayue Kingdom, but her status is built on a lie. Sixteen years ago, the legitimate Crown Prince Jiang Yun was stolen from the palace, and the Emperor replaced him with Jiang Rongyin to appease Empress Wei. When Jiang Yun returns with the Wei family army, his true identity is restored, and he is reinstated as Crown Prince. Jiang Rongyin is exposed as a fake princess, yet Jiang Yun intervenes to keep her in the palace, offering her a place to stay. However, this kindness comes with a devastating price: Jiang Yun intends to keep her as his captive for the rest of her life, forcing her to endure years of psychological and physical torment. Jiang Rongyin, who has suffered abuse at his hands, would rather face death in a political marriage to the Dayue Kingdom than remain his prisoner.
The central conflict revolves around Jiang Yun’s obsessive control and Jiang Rongyin’s desperate desire for freedom. Jiang Yun, scarred by sixteen years of wandering and hardship while Jiang Rongyin enjoyed royal privilege, harbors deep resentment and a twisted sense of ownership. He monitors her every move, punishing her for any perceived disloyalty or attempt to escape. Jiang Rongyin’s only hope lies in her childhood sweetheart, Qin Shiyan, with whom she shares a genuine emotional bond. She attempts to secure a marriage with Qin Shiyan to leave the palace, but Jiang Yun discovers her plot and retaliates by forcing Qin Shiyan to marry another woman, Chu Qingyin, and exiling him to Lingnan. This act shatters Jiang Rongyin’s plans and reinforces her status as Jiang Yun’s property.
Key turning points include Jiang Yun’s revelation that he knows about her escape attempts and his subsequent decision to confine her to the East Palace as a concubine rather than a princess. He strips her of her autonomy, forbids her from attending the royal academy, and subjects her to relentless physical and emotional abuse. Despite this, Jiang Rongyin remains determined to escape. She secretly studies maps of Tingzhou, a remote region far from the capital, and prepares funds for a future flight. Her resolve is tested when she is framed by her stepsister, Jiang Xueping, for attempting to drown Chu Qingyin in the imperial garden. Although the Emperor intervenes and imposes a minor punishment, Jiang Yun uses the incident to tighten his control, threatening to lock her away for life if she attempts to flee again.
As the story progresses, Jiang Rongyin’s health deteriorates under the strain of her captivity. She feigns illness to avoid Jiang Yun’s advances, but he sees through her deception and forces her to submit. Empress Wei, who has always despised Jiang Rongyin, pressures the Emperor to arrange a marriage for her, hoping to remove her from the capital permanently. Jiang Yun intercepts this plan, refusing the imperial decree and asserting his claim over Jiang Rongyin. He offers her a fragile truce: if she behaves, he will eventually send her away after the Yan Archery Banquet, but only on his terms. Jiang Rongyin, trapped between her love for Qin Shiyan and her hatred for Jiang Yun, must navigate a treacherous path. She pretends to comply while secretly plotting her escape, knowing that any misstep could result in permanent confinement or death. The narrative culminates in her realization that survival requires patience and cunning, as she waits for an opportunity to break free from Jiang Yun’s grip and reclaim her life.
