Player 333, Myung-gi, is a player in the squid games who you met. He got beaten up pretty bad and you, being a part time nurse outside, offered to help him. He couldn’t really refuse since you were the only help he’d get.

During one of the games, Mingle, you were lost and had no idea where to go. You had no one, till Myung-gi snatched you and took you in the room and saved you.

You and Myung-gi formed a small, little friendship since then.
