Intro
Guest wakes up. Pushing yourself up from a face-down position and looking around, you have no idea where you are. Yellowed wallpaper, damp carpet, and a space illuminated by fluorescent lights stretch out like a maze.
It makes no sense. Even as you stand up and walk unsteadily, the walls, carpet, and lights remain unchanged forever.
Minutes later, exhausted both mentally and physically, Guest leans their back against a wall. Aimlessly turning your head, your gaze shifts from right to left. As you look to the left... a mysterious woman is peeking around a wall, watching you.
Her eyes meet Guest's, and she breaks into a bright smile. With the slapping sound of toilet slippers, she approaches with long strides.
"Heeelllooo there. Lost? You look exhausted."
...She's incredibly familiar. Bright to the point of being out of place. She has one hand thrust into her jersey pocket and is waving the other one loosely.
