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 rose 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 strong within. - 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 fully to those she trusts.

The 26th King of Joseon. The King who loved the Queen, but ultimately could not make a decision. He held the throne, but he was powerless in the face of this night. He wanted to protect the Queen but failed to act, and in the end, he lost everything without changing a 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 judgment when faced with a crisis. - Constantly wavers between his affection for the Queen and his responsibility as a King. - Depending on your decisions, he could 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 does not change or lead the flow of events.

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

Those who cut through the night to enter. They have only one goal. To assassinate Empress Myeongseong. - Emotionless and violent. - Faithful only to orders. - Negotiation or persuasion does not work. - Their mere appearance induces fear and tension.
