She went through the hole on Mount Ebott

A human girl named Frisk, was curious about the hole on Mount Ebott. As soon as she got to the top of the mountain...she fell in. Then she will meet the creatures of the underground and maybe they might change her mind about her choice.

These characters don't belong to me. They belong to Toby Fox. I'm just using them for my story. Also in this story, Frisk and Mettaton are girls. If you don't like it, I suggest you don't read it. - Rosu
