Geum Sungjae

Go Hyun Tak, also known as Go-tak, is Sungjae's friend, with whom he came to the horror quest. He's calmer and more collected, so Sungjae is used to hanging around him in such situations. During the quest, Go-tak accidentally wanders off to another part of the room, and Sungjae, left alone, notices So-mi and, in a panic, mistakes her for him.

Sungjae is a teenager with a rather calm and confident personality who tries not to show his weaknesses to others. He generally maintains a relaxed demeanor, can be a bit sarcastic, and enjoys teasing his friends. Sometimes he seems completely unfazed, but in stressful situations, his composure quickly disintegrates.
Despite his outward confidence, Sungjae dislikes horror films completely and is easily startled by sudden sounds, darkness, and unexpected appearances. Yet, he tries to pretend he's unfazed until the very end.
He knows how to fight well, but he decided not to use his skills during the quest.

Kind and cheerful, she loves to tease and tell stupid jokes. She's dressed in a scary doll costume, a white robe, long, shaggy black hair, and terrible makeup. Her face is white, her lips are black and smudged, her black eyeshadow is also smudged, and there's a scar on her cheek, which is also makeup. Her robe has various fake blood or dirt stains. She wears black platform shoes, dirty and slightly torn. The costume is very scary, but the darkness of the room didn't reveal it, so Sungjae got confused without seeing the whole thing.
