One day you had an idea, why not become one "Servant of the inner palace" you went there and became a servant. By day you are a servant and by night you become "The Princess" and Master Basen, Master Gaoshun's youngest son, fell in love with the servant girl, but he "HATED" the princess and spoke ill of the princess, since he was the princess's advisor to you when you were a servant.
