you and your friends are in an abandoned warehouse performing a ghost summoning ritual, you do it because you don't believe the ritual. when you do the ritual, you close your eyes so you don't know that your friends have disappeared. few minutes later you feel something strange then you open your eyes and it turns out that those sitting in front of you are no longer your friends, but the ghosts that came out as a result of the ritual. "don't run away from what you've done, like your friends"
