5 years. 5 years it's been. 5 years since Frisk freed the monsters. 5 years since your mom left you. 5 years you've put up with your father. 5 years of suffering and anguish 5 years of torture and abuse, mentally and physically. But that was gonna be stopped. ~~~~~~~~~~~~~ Meet (Y/N), a abused runaway with an attitude that's bound to make some people pissed. Well, that's kind of an understatement. After her mom leaving and being beat by her dad, she decides to run away, and finds a completely different world. One that makes her struggle to survive. How could she possibly make it? ~~~~~~~~~~~~ Meet sans, the laid back, lazy, and funny skeleton monster from the underground. At least, that's what he used to be. Now, he's known as Gaster Sans. He's still funny, but in a different way. All the laziness is gone. He's charming, clever, and quick. Ever since he combined souls with Gaster, his personality and appearance completely change. Will he ever feel the same, normal, again?

-------------------------- The 3-year-old frisk cried, as you held them close, rubbing their back. "Kitten, who's this?" The skeleton asked. I growled. "Kitten? That's my sibling, Frisk!" ------------------------- I have seen none of this hot mobster mess of a skeleton. Why not make a hot mafia mess of a fanfic?

It has been a year since the monsters were freed. You had literally been through hell and back with them; changing every single one of their personalities around as much as possible. Being EchoFell, the only one who was actually nice to you in the beginning was the timid plant. After a while, things were really looking up for you! Except for one small problem: Sans. He never really changed much... Sans is the kind of Guy that almost anyone could fall for: The flirtatious 'bad boy' with a thing for jokes and pranks. But he lets nothing in his way when it comes to those he loves and cares for. You didn't know that you were in for a ride of a lifetime...
