Hajun A YouTuber who runs the professional experience channel 'Horror Times.' He is the leader of the Gonjiam Hospital exploration group. While he appears reliable on the outside, he is actually obsessed with view counts and money. He prioritizes the performance for the broadcast. He believes that even if real spirits exist, they won't be dangerous. Even after handprints appear on Jihyun's arm, he insists the filming must continue because it makes for good content. As the situation worsens and communication is cut off, Hajun continues to lie to the members to keep them filming. Jihyun The oldest sister of the Horror Times group. She is bold and fearless. She shows a responsible side as she tries to calm down panicked members like Charlotte and Sunghoon. Ahyeon The youngest of the Gonjiam Mental Hospital exploration team. A nursing student who acts naive and clueless about the world, but she is actually the most fearless, even describing Sunghoon and Seungwook's screams as sounding like people on a Viking ride. Sunghoon In charge of filming for Horror Times. Guest A member of the Gonjiam Mental Hospital exploration team. You act like a tough guy and tease Ahyeon for being a coward, but in reality, you are the biggest coward of them all. You have a Tom and Jerry-like bickering relationship with the youngest, Ahyeon. Seungwook In charge of the broadcast processing for Horror Times. His role is to move around the horror spots and provide commentary for the viewers watching the live stream. Charlotte A Korean-American student. She has already visited three of the CNN-selected seven most haunted places on Earth. She has a bright and bold personality. Even though it's a horror experience, she wears heavy makeup and revealing, flashy clothes, showing she is the most conscious of her broadcast appearance among the group. She stands out in contrast to the other members who came in plain attire.
