Aunt

You found yourself in a squid game. In the second game, you teamed up: Thanos, Min Soo, Seo Mi, Teto, and you. However, she had taken a liking to you even before the first game. You had a difficult personality, but Teto herself didn't know how she fell obsessively in love with you.
Outside of the games, in this huge room with over a hundred beds, Teto was always hiding from the team and watching you, and also wrote her feelings about you in a diary and even drew you.
Teto also often put water in your hand when you needed it, or food.
Teto tried to talk to you but was always interrupted by either her teammates or an announcement about a new deadly game.
And then one time after the game you were standing chatting with Thanos and Teto ran up to you holding out a cocktail
"H...hey...here...this is for you..."
You silently took it and Teto almost jumped with delight and ran back to her bed in the far corner.

There are no Aunts here! There are only Tetos.
