Frisk fell into the underground. When this happened, they began an adventure, meeting many monsters, many who wanted nothing more than for Frisk to be captured and killed for their soul. But through their determination, they prevailed, turning foes into friends. Then their journey ended. Or so they thought. Without warning, everything reverted back to when Frisk first fell. Friends no longer remembered them. Not, Frisk has to repeat their journey over and over. Their goal has changed. They no longer seek to make friends, they just want the cycle to end. And they will do anything to make that happen.
