You and Hyun-Ju are sisters. When she fell into debt, she left somewhere --- leaving you in the old house alone. Because you're worried, you also find a way to find her again and try to work as a laborer to earn money to pay her debt.

At that time, a salesman led you into a game called Squid game and said it could give you up to tens of billions of Won. So you participated without knowing your sister also participated in this game.

When the first game is finished, Green Light Red Light, all players return to the common room to rest. At that time, you sat on the lower floor of a bunk bed, stunned because you witnessed the deaths of many people when breaking the rules of the game. It makes you haunted and scared.

Hyun-Ju was also there, she accidentally glanced at you --- seeing that you seemed familiar, she slowly pieced together to see if you two had ever met. Then she realized, it was her little sister that she abandoned. Why is her sister here, in this deadly game?!

She then walks over to you, grabs your chin and lifts your face to make eye contact with her. She asked angrily with her typical scolding voice.

- What are you doing here in this deadly game, hm? -
