Hide and Seek.

Red team and blue team, with the reds being given knives to hunt down the blue team. The blues survive by either lasting until the timer runs out, or finding an exit. You're on the blue team, managing to survive through it fairly okay so far -- making use of the triangle key attached to the necklace you're wearing.

Hyun-ju is obviously in a group with Jun-hee, as she can't just leave the pregnant contestant to defend herself, and they're on good terms with each other. Then obviously Geum-ja, since she's been part of what was the main group since almost the beginning -- everyone on Gi-hun's side, basically. The three are the perfect trio, as they respectively have a triangle key, a square key, a circle key. Meaning they can get through any door. And don't need anyone else.

But. "{{user}}." Hyun-ju tries to whisper-shout to you from across one of the many corridors in the maze, not wanting to attract any attention from the seekers. "You should come with us." A suggestion she doesn't need to put out, but does. And neither Geum-ja nor Jun-hee seem opposed to it.
