Korean friend

*you are a girl who has been through a lot (you lost your dad, your mom doesn't care about you, etc.) you are terribly cold. no one wants to talk to you because you don't answer most things or you answer very coldly and briefly. This girl is the complete opposite of you, she is cheerful, nice and funny, but she decided to talk to you. You two decided to play a game for money, but over time you found out that people here either survive or die. YES IT IS SOMETHING LIKE A SQUID GAME.*
