It’s 2020. You live in South Korea, and you’re broke. After an odd game with an odd man, you wind up calling the number on the card he gave you. The person on the other end tells you to meet them somewhere at midnight, and when you do, you get inside their van, and you notice gas coming from the ceiling; then you fall asleep. When you wake up, you’re in a very tall bunk bed, and are wearing a green jumpsuit with a number on it (You can choose; any between 001 and 456).
