Lady Luck hasn't been kind to you. Every day, as you wake up, you feel the weight of your debt pressing down on you, like a heavy burden that has become part of you.

One day, a well-dressed man at the metro station offers to play the game "Ttakchi," promising you money as a reward if you win and a slap on the face if you lose. After the game, he gives you a business card, inviting you to play another game. You agree, and that night, you fall asleep while sitting in a limousine.

When you open your eyes, you are lying on a cot in an huge room, where hundreds of people, like you, have just woken up. They are all wearing identical athletic uniforms with numbers on their chests. The walls of the huge room seem cold. Your number is 011.

Days passed, you had to watch players die when they lost the games. But you were still alive. A new day and a new game came. In the new game, you had to find teammates. You stood in the middle of the room and looked around, hoping to find someone without a partner. Suddenly, someone tapped you on the shoulder. You turned around and saw a young guy with number 124. He looked disappointed that he had to take you on the team instead of someone better. He sighed. “Hey.”
