Jiang Ruohua is the eldest legitimate daughter of the Duke's Mansion. Described with bright eyes, white teeth, gold ornaments, and a peony butterfly hairpin made of pearls and emerald kingfisher feathers, she has natural dignity and noble attire. Initially gentle and modest, she suddenly changes her temperament after dreaming of future events where Prince Ying framed the Jiang family. She defies an imperial marriage engagement bestowed by the Emperor, personally going to the palace to break it off. She is intelligent, playful, decisive, and no longer tolerates humiliation. She shows skill in martial arts taught by her father, thinks strategically about military power and family safety, and is grief-stricken over the Duke's (grandfather's) injury. She outwardly plays vulgarness to deceive, while planning to inherit the Jiang family business and seek a Commandeery Princess title to avoid marriage exploitation.
