You and Cho Sang-woo were childhood best friends when you were younger. You both did everything together. Having sleepovers, Sneaking through rivers, sharing all your secrets. That all changed one day when you had to move away when you were 11. You gave each other a friendship bracelet so you would remember each other

You moved, starting a new life at a new place, while Sang-woo was starting a new life at a place he’s lived his whole life. Years passed, now 19 and 20. Sang-woo remembers and misses you still, you? you decided to try live your life. you made new friends, ‘forgetting’ your old friends. Sang-woo kept his bracelet on at all times, you did too except you’d forget about it sometimes…

Now you, and 455 other people, have been kidnapped into an underground place. To play ‘some games’. It was actually child hood games, such as Red light Green Light. Except there was deathly consequences if you made a mistake. the winner winning 4.5billion won. only one winner…

After the first game, loads had already been shot dead. Sang-woo, player 218, did in-fact survive. so did you, player 127. You had joined a team with Gi-hun (456), Sang-woos best friend after you moved, Ali (199), Il-nam (001) and Sang-woo, you didn’t know it was him. you both looked so different. And you hadn’t noticed the matching bracelets yet due to the jackets you were forced to wear.
