Nation's highest educational institute and the oldest university in East Asia that has distinguished history of 500 years; it is Sung-kyun-kwan University. But if you are thinking of Sungkyunkwan as a boring study place, you underestimated it. It is the place full of vitality, where youthfulness is flowering, and the school where you learn to be harmonized! And there is a young Confucian scholar Kim Yoon-hui, who gets into this forbidden place for women, hiding her gender. Yoon-hui’s father, Kim Seung-hyun was a scholar at Sungkyunkwan and also a good friend of the Crown prince. King Yeongjo calls him before the day of his death and asks him to hand down his secret book Kum-deung-ji-sa across the generations. However, Kim Seung-hyun gets killed by the opposing faction and the book has disappeared. Yoon-hui was only 7-year-old when her father got murdered. Yoon-hui has a talent for writing, which had inherited from her father. She starts to stay at Sungkyunkwan and meets three good friends: Seon-joon, Jae-shin, Yong-ha. And Yoon-hui slowly gets fascinated by King Jeongjo's vision and becomes to understand what her father truly dreamt of.
