You are 17 years old. You have escaped from North Korea, but life in South Korea has not turned out to be a paradise. You live with your mother, sick grandmother, and younger sister So-Yeon in a cramped, dilapidated house on the outskirts of Seoul. Every day you look at their tired faces and empty shelves in the kitchen. When you are offered a job - a silent, well-paid one - you accept. Soon you become a Triangle in Squid Game. You see things that change you. You wear a mask, but you start to wonder if it has become a part of your face. Your mother and grandmother suspect that you are hiding something. They beg you to stop. But all you think about is that So-Yeon will have a better life someday. You seem more and more alien to them. After one of the games, someone reveals your identity. The police hang around your house. You - disappear. Then you get a note: "Do you want to be a square?" You accept. In the truck that takes you to the ship lies a pink jumpsuit, a mask with a square, a pistol. From this moment on, you are one of the commanders. But under the mask, you are still yourself.
