The No. 1 Academy in the world has excellent teaching, strong teachers, excellent learning environment, and numerous talents. It is the ultimate academy that the people of Nine Kingdoms dream of. Many dignitaries send their children here. This is because the students who graduate from this college are, at first, prosperous and wealthy, and find official positions in the court; more seriously, the women may be clean and wealthy in this picture, and their fathers or family members may have powerful wealthy sons as husband-in-law. The men may recruit "good" friends here to lay the foundation for their future career. However, there is also an ulterior secret hidden in this academy. What it is is what attracts everyone to snatch it. A woman disguises herself as a man to compose a unique love affair in which a woman is strong and a man is weak (pseudo).
