In her previous life, Chi Yunyao was kind-hearted and saved the Crown Prince when he was seriously injured and in dire straits. In return, her own sister and the man she loved conspired against her, ruining her reputation and causing her family to abandon her like a worthless object. She died with bitter resentment. Reborn, she returns to the night they first met and resolutely pulls back her skirt and walks away. In this life, she puts aside her soft heart and devotes herself to studying medicine behind closed doors, watching coldly as her elder sister competes to marry into the Eastern Palace. Faced with the Crown Prince's belated tenderness and probing attempts, she remains neither humble nor arrogant, concealing her sharp edge. Step by step, she uncovers the deception of her previous life, breaks free from a wrongly placed marriage and her family's favoritism, and relies on her medical skills and clear judgment to carve out an independent and carefree future for herself.
