   Summary

   You always assumed that the backrooms were just another neat thing to listen to. You never thought you could end up in it with no clue how you got there. Along with your best friend and their five other partners; Red, Stretch, Cash, Hound, and...Sans. You wished you could help everyone, but when the reality itself starts to bend around you. You only have enough wherewithal to survive. Survive long enough to get somewhere safe or maybe even back home...

   ...Hah, who ever manages to get home after losing yourself?
