Summary
So, the general idea of this fanfic is that Chara never commits suicide and because of it they are still alive when the other humans come to the Underground.
They still hate humanity, but nevertheless aren't willing to commit suicide as they don't wish to leave their family behind, even if that selfishness means Monsters remain trapped in the Underground.
Then four years into their era the second of the eight humans arrives to the Underground, the one who arrived didn't trust Monsters and had in fact come to confirm whether the first human was dead, the fact that they weren't may be the only reason some peaceful resolution can be attained one day...unlikely, however.

Summary
Gather children, listen well, harken to the Under Tale.
A story of a small child, falling into a massive cavern where monsters have made their home. With the help of a certain phantom, the child makes their way through the Underground, making friends & family along the way.
I own absolutely nothing in this. Undertale, along with with characters, setting, etc., belong to its respective owners, who are not me.

Summary
“Sans!” Papyrus’ voice broke Sans from his thoughts and he turned around to see Papyrus holding a tiny fluffy animal on his lap which they’d learned was a “kitten.”
Papyrus’s eyelights were heart-shaped and glowing and a wide smile stretched across his skull.
“Sans! It is adorable! This little creature immediately approached me and started rubbing its face against my rib cage. All while making the most peculiar rumbling sound. It likes me! I think it wants to come home with us!”

Summary
Frisk's determination was a helpful, powerful gift... before it became a curse.
When a dangerous entity known as "The Player" takes over, Frisk is helplessly left at the mercy of a power much higher than theirs. One outside reality, guided only by an insatiable curiosity.
At first, The Player's control would muffle their feelings and force them back underground after they escaped. Very soon, the experiments and runs become much worse.
First it was death, then manipulation. There's always something new, unfound secrets to quench The Player's endless thirst for more.
Will it ever be over? We can only wait and see...

In the small town of Hometown, everything is almost normal. Most of the towns population is made up of monsters, except for one. Kris (Age 17), the adopted child of Toriel and Asgore Dreemurr. Their brother, Asriel, attends a good college far from Hometown, as Kris goes to a fairly small high school. In the school, Kris sits with 14 other students, they are mostly silent, only talking when necessary or when they feel comfortable, often sleeping in class and not calling any attention. Susie (Age 18) is one of the students, a troublemaker who had been held back one year, nobody knows much about her, and because of her reputation, nobody dared to find out. Everything seems as it should be, until fate puts Susie and Kris into an adventure that would forever change their lives.
