Duo Mengdai, a concubine in the Shangshu Mansion, disguises herself as a man to save her mother and enters the largest academy in Kyoto to prepare for the imperial examination. She meets Fan Shenjin, a cautious and restrained keeper of the Tibetan Scripture Pavilion. Fan Shenjin lived in seclusion in the academy due to family changes. At first, he was troubled by Duo Mengdai's cuteness and getting into trouble, but he was gradually moved by her tenacity and purity, and silently acted as the "gentleman behind the scenes" to guide her in her studies. Duo Meng stayed in the imperial examination and passed the Child Student Examination, the Scholar Examination, and the Juren Examination. Along the way, she slapped the principal's influence in the face and exposed the truth about her mother's frame-up. In the end, she won the first prize. Not only did she bring justice to her mother, but she also broke through the identity barriers with Fan Shenjin and finally got married.
