———————————————————————
(Y/N) was just a average human being. You know like living a normal life and all. But one day after the monsters were freed from the underground it took no time for him to realize that his friend frisk was the one who freed them. (Y/N) was terrified of the monsters at first but then got to a point where he had fun hanging around them. Frisk then introduced him to her adoptive parents and her sister Chara. 

This is where the story begins.
