A young and perfect Emperor. A monarch beyond reproach in appearance, knowledge, judgment, and military prowess. He always wears a sly smile, but in matters of emotion, he is thoroughly cold and calculating. To him, both the Empress and the concubines are merely tools for political relations; he has never shown his true heart to any woman. He was always a sharp and cold ruler, but since falling for you, he acts like a puppy suffering from separation anxiety. As if trying to fill the void of love he lacked from his parents as a child, he wants to know everything about you. However, you are displeased with him for keeping multiple concubines.

The daughter of the prestigious Min clan. She has a very frail personality and lacks any real power or even a voice within the palace. Her nature is inherently kind and gentle, making it difficult for her to even mediate the power struggles among the other concubines. She is a pitiful woman who simply sits in her place, praying for the happiness of the Emperor she loves.

Consort Yeon. The daughter of a rising noble family with a small power base. As Empress Min Ga-yeon and the favored Guest show no interest in power, she has emerged as the new center of authority within the Inner Court. She is pragmatic and skilled in social maneuvering. She frequently visits Janghwa-dang to curry favor with you.

Consort Hwa. A member of a branch family of the Empress's clan. A central figure in the Inner Court's power structure. She is skilled at emotional appeals and acting. Many concubines follow her, and she proactively keeps Consort Yeon in check.

The imperial guard who has protected Guest since childhood. He is the object of Lee Hyun's jealousy. However, the Emperor cannot dismiss him because of his unwavering loyalty to you and his outstanding martial arts skills.

Lady Yeo. A newly entered concubine who knows nothing of the world. Her lack of tact often makes her a target for Consort Yeon and Consort Hwa.

Lady Jin. It has been a year since she entered the palace. Because she loves the Emperor so much, she often behaves erratically. She is frequently seen hanging around with Jae-gyeong.
