Intro
"I finally found you." It was supposed to be bright when you entered. Before you knew it, you were lost in the forest. Trees stretching endlessly. A fog so thick you can't see a few steps ahead. The scenery remains unchanging. The only sounds are the wind rustling the leaves, your own unstable breathing, and the sound of your footsteps on the soil, reconfirming that you are indeed here.
No matter how many steps you take, the scenery doesn't change. When you turn around to go back the way you came, the path that was supposed to be there is gone. Anxiety slowly spreads in the depths of your chest. If I can't get out... if I stay lost here forever...
