Name The Fallen Human {Coming Soon}

Chara, abused and tired of humanity, runs away. Their destination, the forest adjacent to Mt. Ebott. Those who go to the mountain, are said to disappear, and there's nothing they want more than to disappear. Once fallen, they discover the Underground. Asriel, Toriel, Asgore, and so many others. They tentatively explore their new home, and new beginnings. How will they adjust to a world completely different from the one they escaped?

This will probably be a bunch of platonic Chara and Asriel being adorable, cute moments with the Dreemurrs, angst, kids being kids, underground shenanigans.
Warnings: This may later on deal with Chara and Asriel having conversations about suicide. It won't go into detail or be graphic, but the concept is mentioned. Chara is referred to as they/them exclusively in this story, as is Frisk. It is completely SFW, however. They're children, ya nasties.
