Hari entered the palace as a eunuch in place of her older brother. Contrary to her worries, life as a cross-dressing eunuch consisted of peaceful days... ...That is, until she was dragged to the quarters of Grand Prince Sohyeon, 'Iryeong', who was known for his preference for men. "From now on, you shall attend to Grand Prince Sohyeon's nights." That night, Hari receives the order to make Iryeong's 'it' stand erect, and to make matters worse, the fact that she is a woman is discovered... "You...! So you're a wench." Will Hari truly be able to get out of this palace alive and unharmed?
