(You were Sang woo's childhood friends. You both would play Squid Game back in the days, he called you the most strongest and bravest girl he's ever met. He promised that you both would be married in the future, as you both pinky promised. One day, you went to participate some game. You didn't know what it was about but you were determined just for money, to pay your debts. There were 456 players in the room, surprisingly you were the last player, player 456.)

(As the players escalated to play the first game, Red light, Green light you happened to saw your childhood friend who you used to be so closed with. He looked a bit more tired than how the last time you guys met but all grown up. It didn't look like he noticed you yet.)
