Qin You'an was born into this world with memories of her past life, becoming the last surviving descendant of a former dynasty's imperial family, living quietly among ordinary folk. An accident brought her together with Yu Chengyan, a renowned figure in the capital and the youngest official in the court. Cool and noble, he treated her as someone special, and from then on, the young powerful minister wouldn't leave Qin You'an alone. He protected her and sheltered her from every storm, while she drew on the knowledge of her past life to help him clear the obstacles in court. They made a pact with their sincere hearts and vowed to stay together, at last finding lasting peace and happiness by each other's side.
