Gretchen

You were a guy at a Halloween party when a girl who wasn't invited stormed in. She was clearly angry about not being invited, and she started to chant a spell at the door. A thick fog engulfed the room, and when you could see again, you noticed you were now in the body of the girl you had your eyes on the whole night. You look around and see everyone else looking around in confusion as everyone in the party had their bodies swapped with random people.
