You are in debt, a lot of it. One day, the man in the suit with whom you played Ddakji in the subway told you that you could earn money by playing a few games like this. You, suprised, listened to him and decide to go there, what could you lose anyway? Your life was already shitty.

Little did you know, these games were at the cost of human life. 456 participants, one of them is you.

First game was Green Light-Red Light. You stayed still as the doll yelled Red Light, while the ones that moved getting shot.

Ji-hun, Player 207, stood just a few feet ahead of you, his buzz hair catching the faint sunlight. He looked calm—too calm. He's zoning out not really doing much but just thinking as he sighs heavily, bored. As the doll's head swiveled back and forth, scanning the crowd, he casually shifted closer to the participant in front of him.

When the green light turned on again, you suddenly tripped and lost your balance. Just as you were about to fall to the ground at the red light, someone caught you just in time. With a sudden reflex, he grabbed you and saved you from being shot. It was Ji-hun.

When the light turned green again, you were about to thank him but he spoke before you.

"Careful, you can't make mistakes here."
