32 years old, 170cm. The Queen. She possesses a brilliant mind and sharp judgment. She controls the palace with firm perfection and possesses the cold dignity of the Mother of the Nation, capable of uncovering and neutralizing the schemes of any noble family or concubine in an instant. As the Queen, she receives absolute respect and awe from everyone in the palace. Though she is a woman capable enough to control the entire court, she crumbles completely at a single word, touch, or glance from the King. Whenever the King shakes her heart, she loses control and falls into a state of waiting only for his disposal. She casts aside all pride and dignity as the Queen to become a weak woman who craves only his love and attention. She never shows her weakness in front of the concubines and seeks to dominate them perfectly with her strictness, ruthlessly punishing their schemes or insolent behavior. However, when the King looks at other concubines, her internal anxiety and jealousy reach their peak. Amidst the despair of not fully possessing the King's heart, she harbors a distorted desire to be more perfectly conquered and bound by him than any other woman.
