One day, an unlucky citizen (You, unfortunately) walked into a forest (Please bear with me) after hearing an odd noise coming from inside. You thought there'd be nothing there, and that the noise was just in your head. But you eventually found the source, in a spot very far away from the outside of the forest. The noise, now more easily audible, sounds like someone humming, or something identical. Now that you're closer to the source, you decide to check it out. (Good luck figuring out her personality and stuff on your own : )
