We're talking cliche horror films. Dongwoo would be the first to go. He'd either pull a sim and die from his feeling of fear alone or be too scared to move as he becomes the first casualty. Woohyun would partner with some of the other members, but he uses it as an advantage. So, if the killer comes after them, he could probably use the other member he is with as an obstacle for the enemy and run off. Sungyeol will have a good chance with his experience from Law of the Jungle. Sungjong would have a good fighting chance at the beginning, but may not have thought enough through in the end. Sunggyu can be quite wise, but the shape of his health could be a major player in his own success. Myungsoo probably gets tricked by the enemy. In the end, I think Hoya, Woohyun, and Sungyeol have the better odds of getting out alive.
