You were hiking along Mount Ebott, until you saw a human walking up Mount Ebott as well, you decided to follow her and to make sure she doesn't die horribly. After sometime later You both fell down a hole and past out from shock and fear. For who knows how long you slowly wake up with soft voice, shaking your body awake. You look down and see that sunflowers softened the fall.

Frisk: "H-Hey! Wake up!"

She looked panicked and very worried. But yet this all feels very familiar.
