Summary
A new life begins for you and your little sister, Neelam. That new neighbourhood is the chance you need to erase the past mistakes and those terrifying fifteen years you passed in a foster family.
You are not the only one who’s running away from the past. Your neighbour, Sans, affected by a strange illness that’s causing him memory loss, is worrying you. At nightime, he’s wandering in the streets, lost, like he is chasing after old demons. His brother, Papyrus, can’t look after him for the moment. Since you are in desperate need of a job, he’s asking you to do that for him.
You know it is not an easy job, but how complicated can that be when Sans is all but cooperative? -

“Would you be down to come to my house on Sunday to meet my parents after church?”
Sans was taken off guard by the sudden demand of Y/N and scratched the back of his big bald cranium, embarrassed.
“Oh, hum yea, sure, human, everything for you pookie.”“Great ! Just… be careful, my parents are… well…
Y/N looked away, searching for their words, but after a couple of seconds, they just brushed it off and laughed nervously.
…I guess you'll see. Just try not to make too many jokes, okay?”“Hm. Oh. I get it. Your parents are skibidi stuck with a stick of butter up their gyatt. I'll be careful.”

Summary
On November 23rd, 2096, Clover Callahan jumps down into the Underground on a mission of justice. And on that journey, he meets wonderful but hurt people, and does what he can to help them. And in the end, he sacrifices his SOUL to bring monsterkind just one step closer to freedom. He knows it isn't enough, not yet. But it's what monsterkind deserves after what humanity has done to them. It's what his friends deserve.
But is justice really all it was? No one jumps down into an infamous mountain without some sort of pain. Without a broken home, or perhaps a broken heart. Or maybe some unfortunate combination of the two, alongside other factors. So join me, as I tell you of Clover Callahan, and everything that leads to what is perhaps the best, or maybe worst day of his life, but definitely the last.
Injustice calls, and he can't help but answer.
OR: Clover's life on the surface

Summary
You don't need the Underground to have an emotional journey. Sometimes, ordinary life itself gives you enough problems to last a lifetime.
In a world where monsters and humans live somewhat in peace, where no war has ever separated the two races, where no Underground brought the despair for freedom, sometimes the biggest of your problems can be...
... embarrassing yourself in front of royalty.
Clover thought that being the only human in a town of monsters was the most of their worries. Fate had other plans. Now not only did they mess up their first ever interaction with another human after a long time of never meeting one...
They were also a royal. AND their classmate. AND was assigned as their personal school tour guide. Clover was not living up to their name in the slightest.
Meanwhile, Chara meets a human their age for once in their life and encounters surprise after surprise. From their strange behavior to a seemingly complicated past, Clover was an enigma to them just as they were to Clover.
But little do they both know, they're not so different underneath the surface.
