Summary
Their King is dead. The six Souls are Gone. Their future lays in ruin.
Frisk has slipped through the barrier and left the monsters with shattered hopes and a toppled monarchy. With no witnesses, it was pure, selfish regicide. They were loved by all, and thus, their betrayal cut all the deeper. For the third and final time, humans had stolen everything from them.
Anger has a way of changing people. It remains in the Soul even as memories fade.
Frisk may be gone, but the RESETS continue, multiplying the resentment within them and morphing the residents of the Underground into tightly wound reflections of their former selves. No longer in a position to do nothing, Sans is Determined to find a way past the barrier for the sake of his brother, and for the sake of vengeance.
He’ll give anything to achieve that goal. His Soul included.
He’d found an alternate method that should work, buried deep inside a gilded dusty tome in the royal library. Instead of using LoVe to pass through the barrier, Sans was going to use love. He was going to have to gain a consenting human, and convince her to bind her Soul to his. Permanently.

Summary
Betrayal and deception are the order of the day in the state of Undertail, located in the Underverse. A state where there are small rural towns of poor people and cities with rich or middle-class people, but in this story, we're going to focus on the tale of a particularly imbecilic group of idiots, who will suffer on hands of the rich:
King Ganz of UnderToes
The Lord twins of DreamTale.
The Unknown King of Underverse, Cross.and the worst of all...
Landlord of the nine mud pots, Ink Comyet of Underverse.
+++++
Just to clarify, I'll be adding tags as the story goes on, but I think I already added the important ones, most of the new added tags may be from characters; there will be no gorey violence, just dumb silly violence treated as serious, no explicit sexual content because I don't find it that interesting to write, and I think that's it.I'll be updating whenever I feel inspired or I have time, because I'm soon to go back to college and I may not have much time anymore, therefore, if I DO update, it may be short, I just wanted to clarify that so you guys don't feel too annoyed at the wait for a short chapter.

Summary
“it’s just…you keep acting like something horrible is waiting for you at the bottom of this mountain.” His whispered voice was calculated and obnoxiously observant.
Frisk chewed their lip and felt their nails subconsciously start digging into their palm. The last thing they wanted to do was ruin anyone’s excitement about the surface with their own anxieties. If anything, they thought they’d been hiding their fears pretty damn well.
“There are some things, Sans…” their voice seemed to start against their will, hushed and constricted. They put a hand over their heart, which was beating restlessly.
“…that I just can’t explain to you,” Frisk finished exasperatedly.
