Monsters was released from the underground three years ago, Humans are hesitant to Monsters due to their history long ago, the great war. As three years has past, the Humans are now fine with Monsters, some of them are being able to travel and explore all over the world, others can go to human school to learn and have jobs, but most Humans are being racist and still a little scared of them because Monsters are very powerful beings that can easily kill and take their souls easily.

              For some reason, Sans wasn't able to get a job despite that he use to work as an assistant of the royal scientist when he was in the underground, Some of Sans'es { did I spell that right? } friends weren't able to find a job either since they don't have proof -like a certificate, heh Humans. . . - . Sans and some of his friends have no other choice but to go to high school. Thank Asgore they don't have to go to elementary school. Haha that would be hilarious, especially Papyrus, they pass the test they took after all, so they don't have to go to elementary. Sans is laughing at the mental image of Papyrus having class with small human children.

                     Sans hope that they'll be fine in the first day of school, him being a vampire skeleton, anything can go wrong, Heh I mean. . . what could go wrong in first day of school?

{ HOPE y'all like this prologue. Nah it's probably bad -I'm a negative bitch so deal with it!- . So what do y'all think of the sketch that I made for the cover book? the cover MIGHT be permanent tho so yeah, if you hate the cover please don't angry at me because I am NOT an artist  }

{ please don't hate me too much if it's bad cause it's my first time making Sans x Reader book, tell me if I have mistakes, Boi! ;3 )
