Underfell Charisk

Out of the seven humans to fall, only one has ever made it back home. Taking the underground with them. Frisk is the most determined kid there ever was...well, Chara was pretty determined too. That's only one of the reasons Frisk wanted to save the forgotten human. Eventually, after too many True Resets to count, Chara came back to life...with two souls.
She had both her and Asriel's soul while flowey had none, and had been living in Snowdin, constantly trying to keep from going back to the castle with most of her family gone and out of trouble with the two skeletons she lived with. She didn't do that last one very well...
After watching all the other six humans break down her defensive walls and then die at the hands of her friends, will she be able to handle Frisk?
