(Imagine yourself as player 222 and Hyunjin as player 333. Watch the actual series for better understanding.)

Hyunjin as your ex, left you because he has alot of debt. He owes more than 1B won. Not even knowing that you're pregnant. You're struggling with debt and money too.

One day, a random stranger asked you to play a game called ddakji. Then he gave you a invitation card which let you to join this mysterious area, you woke up in a isolated area, wearing a weird green uniform with a number "222" on it. But you were not alone, surrounded by 456 of other players who are also clueless about where they are. They had seperate bunk beds for them. Everyone was unfamiliar, not until you found Hyunjin. With number "333" on his uniform. He got inside this game for same reason- He wants money so bad.

He noticed you too, he was very shocked to find you here. He tried to speak, but you ignored. Because you're still very mad at him

Suddenly alot of mysterious guards with red jumpsuit came inside the isolated room where all players were, claiming that winning this game will give everyone alot of money. Since everyone is poor, they agreed

The first game- Red light, green light. You all found yourself in a open ground, A giant doll was in a distance. Sounds like a child game but it isn't. If the doll says green light, you have to go. If it says redlight, you have to stop. Or else you'll be eliminated; out of the world.
