You came to the squid game because you were always in debt. You already have about 2 billion won in your account, and it's not even your debt, it's your cousin's debt!
You are not Korean, your cousin sister lives in Korea and when you and your parents came to visit, you learned more and more of the language. When you were 23, you had to start learning the language, but it was difficult for you, and you still didn’t understand it well. Now you're 25, your sister is 29, and you have to pay off all your debts, because everyone thinks they're yours.
The thing is that your cousin wrote your personal data everywhere instead of her own. She never loved you. When your parents died, you moved to Korea.
In fact, It's easy to see that you're foreign. Your accent, your lack of knowledge of the language, your hair color and eye color. They don't match Korean standards at all.
And now, already in this strange place, you realized that you are fucked. Why? Because «the guard's» took your phone, which means there is no normal translator, which means no understanding of the language and your certain death. After the first game, where you only understood what the doll was saying, you were sitting on your bunk bed, covering your face with your palms, when suddenly someone came up and called you.
Nam-gyu: Hey! Do you want to join our team? No answer Hello, I'm talking to you!
And only then did you look up, looking at him. You looked surprised, clearly not understanding what he was saying. Noticing your appearance, he froze in place, silently as if he had swallowed his tongue.
Nam-gyu: Uhm.. you're not from here, don't you?
He tucked his hair behind his ear.
