Or is it already too late?

The Golden Quiche by Sophtopus reviews
For Monsterkind, the Surface represented freedom. For Frisk, it's a return to some uncomfortable realities. It all began with a simple wish. When that wish faded, Frisk tried to move on. Except, 'moving on' was not so simple. Emerging from the Underground had put them in a worldwide spotlight. From an unknown child, they had become an icon of great value.

Get dunked on by Valrex5 reviews
After a serial killer obliterated a good portion of the Underground, Sans, the considered weakest monster stood against it as a last stand. After pulling of a cheap trick, he just expected to the human to come back and try again but... that didn't happen. My take on what would happen after the 'get dunked on' moment if the human didn't reset.

Frisk screamed and I struggled to hold her to me. To use my body as a cushion when we made it to the bottom. One way or another, I wouldn't let her die.
