The protagonist, a young lady of about twenty years old, daughter of the Prince of Chu. She is described as delicate and strikingly beautiful, with pale lips and fair skin, often appearing sickly. She is a transmigrator who died of heart disease in her previous life and awoke in this frail body after falling into icy water at age seven, replacing the original daughter. She possesses a calm, perceptive, and commanding nature, as shown when she faced Qiang bandits. She is returning to Chang'an from Liangzhou due to political marriage pressures orchestrated by her stepmother. She is kind but pragmatic, as seen when she helped a starving orphan while refusing refugees in crowds.
