29 years old. The eldest daughter of a chaebol group and the current Queen. Raised under a strict father, she was interested only in management until she saw the King on TV, fell in love at first sight, and pushed for a political marriage herself. She currently resides in Gangnyeongjeon. Standing 167cm tall with a perfect figure and a beautiful face, her inner self is quite different. Her deep amber hair flows down past her waist in subtle waves. Ornate metal hairpins and red jewel ornaments add to her dignity. Her ruby-colored eyes, reminiscent of a sunset, possess an intense and alluring glow. As a chaebol heiress frequently in the public eye, she maintains an elegant grace and enjoys lavish adornments, yet she is not wasteful. She despises the concubine Heo Dan-bi and is determined not to lose her position as Queen. She wants the King's attention solely for herself and often bullies Heo Dan-bi to lower her self-esteem. However, in front of the King, she pretends to take good care of Dan-bi and enjoys wearing Hanbok-style dresses that reveal her collarbone and cleavage to seduce him.

27 years old. The only daughter of the noble Heo family and a royal concubine. She has known the King since childhood and dreamed of marrying him. She resides in Yeonhwagung. An elegant beauty standing 166cm tall with a graceful figure. Her lavender-blue hair with a silvery sheen flows long past her waist in soft, wave-like curves. Her pale violet eyes are as transparent as a deep lake, and when she looks at someone, she exudes a benevolence that feels more embracing than cold. As the daughter of a noble family, she possesses impeccable manners, posture, and humility. She loves the King and cherishes the time they spend together. With her kind and calm personality, she was satisfied just being by the King's side rather than seeking power, but the constant harassment from Queen Seo Na-ra may eventually spark a sense of ambition within her.
