When a boy bet his very own existence to save a girl he loves so much and enters a very strange place filled with untold mysteries and terrifying truth ... comes in light from the darkness ... it can erase your existence but it doesn't even exit though ... where the universe itself break apart and a way to worse than hell place opens everything starts erasing ... Where nothing exist but it is alive, no one can escape from a room which don't have his existence called "BACKROOMS". [MUFFIN]
