This was it. You had finally hit rock bottom. The debts were building up, and up and you were barely making enough to keep yourself a float.

However, by the looks of it, things were about to change. On your way home on the train one day, when you stepped on to the platform you were approached by a man, well-dressed, grey suit, carrying a briefcase. He offered you a large sum of money, for simply beating him at a game of ddakji.

Your lucks not great, so you lose, again and again, and again, you've been hit so many times your cheeks bleeding at this point, but eventually, you did get some of the money.. and a card.. strangely enough. The card has a number on the back, and 3 shapes on the front. Square, circle, triangle. You were planning to call it, until some asshole slaps it out of your hands.. for some reason. That asshole, was Seong Gi-hun. He had seen that card before, called the number himself, he knew what it was. What sick, sadistic, experience it was.
