{WARNING: This fic is INCREDIBLY old, has godawful typos and isn't finished, nor may it ever be completed.} A year passed since Frisk freed the monsters from the underground. They now live with Toriel, and every day is a new adventure as they do their best to help their new friends adapt to living on the surface.

It's Frisk's birthday and it's time for some fun! (We now know about Sans's past...but what about Frisk's? As Asriel asked: why did Frisk climb Mt. Ebott? Well, they have their own reasons.) (Queerplatonic Sans/Frisk. Trigger warnings of emotional abuse. Rated T just in case. Part 4 of my Undertale Series but can be read alone if you want.) (Cover Art courtesy of dogpu on tumblr!)

Based on the prompt "Person B has been having nightmares so person B borrows person A's shirts, which has been helping them sleep." with Frisk being Person B and Sans being Person A. Sans/Frisk. 2nd POV. Can be seen as brotherly or romantic. Post-Pacifist ending. Spoilers to various endings. (Cover Art courtesy of dogpu on tumblr!)
