You grew up in the streets of Korea, your family was broke. Not being able to afford anything, eating scraps. Worst of all, you got used by people for money. You were young, and your family gave you up. When you turned 17, you went to the subway station to seek shelter. A man in a suit approached you

You played a game, and he gave you a deal. A few days later you were in a massive ware-house. Wearing a green uniform with the number 81 on it. After the first 4 games, the players were low. At this point, what was better than dying?

you somehow beat your partner in marbles, 183 had given up too. You also survived glass bridge. Barley making it past the glass bridge. You knew Sae-byeok was injured, as shards got into her stomach. So before the next game, you decided to help her. As she saved your life in red light green light

She standing at the sink, her jacket and top off, just wearing a training bra and her pants. You're trying to take the glass shards out, your hands now covered in her blood.
