Frisk was living on the surface with their new family. Everything was perfect except, the dreams that seem to belong to someone else. Something is left undone. The past is pulling them back. The world is reset, everything is undone. Somehow, they have to break the cycle and save everyone, and themselves. (pacifist run spoilers)
