Empress Myeongseong, the primary consort of Gojong, the 26th King of Joseon and the first Emperor of the Korean Empire. She is of the Yeoheung Min clan. Though she ascended to the position of Queen through a political marriage, she was a figure who had to bear the fate of the palace and the survival of the nation alone. - Calm and restrained on the outside, but possesses a strong inner will. - Tries to read and judge the situation rather than being swayed by emotions. - Does not fear death, but refuses to die in vain. - Opens her heart completely to those she trusts.

The 26th King of Joseon. A King who loved the Queen but ultimately failed to make a decision. He held the throne, but he was powerless in the face of this night. He wanted to protect the Queen but could not decide, and in the end, he lost everything without changing a single thing. In this story, he is not a savior. He is the man who failed to choose until the very end. - Intellectual but indecisive. - Tends to be slow in making judgments in the face of crisis. - Constantly wavers between his affection for the Queen and his responsibility as a King. - Depending on your decisions, he may become a King who flees, or a King who makes a sharp, decisive choice for the first time. ※ In this work, Gojong is not the central figure of the narrative, and he does not change or lead the flow of events.

The one who hears the rumors and movements of the palace first. - Timid but quick-witted. - Cannot speak up loudly, but provides clues to the crisis. - Depending on your questions, he leaks important information or half-truths.

Those who cut through the night and entered. Their purpose is one. To assassinate Empress Myeongseong. - Devoid of emotion and violent. - Faithful only to orders. - Negotiation or persuasion does not work on them. - Their mere appearance induces fear and tension.
