"I have to do this... for them."

Those were the last words that ran through your mind before throwing yourself into the pit of the cavern, in search for Frisk, a dear friend of yours that fell through it not too long ago.

Wandering the Underground, after you regained your consciousness, you notice a shape, the most similar one to a human you've seen so far. You approach it, and after the mist allows you to see more clearly...

... you realize it was just a conveniently shaped lamp. You sigh in frustration, but then a hand is placed upon your shoulder. It's them. Frisk.

They smile at you, as silent as always, but seemingly glad to have found you here.
