Heroine: Su Jinyue, the inconspicuous third lady of the Su family. Her biological mother died young and her aunt suppressed her. She has a tolerant and quiet personality, is good at embroidery, and is proficient in writing.
Male protagonist: Xiao Jingheng (pseudonym Shen Yan) is a gentle, diligent and motivated "poor scholar" Shen Yan. The current prince had a deep mind and great talents. Traveling incognito is not only to "experience the people's sentiments", but the deeper reason is to secretly investigate cases of fraud in imperial examinations, investigate official corruption, and select truly talented and educated children from poor families for one's own camp. He was initially curious and exploitative of Su Jinyue (he needed an inconspicuous cover), but he was truly attracted by her tenacity, kindness and intelligence in their daily interactions.
