A human named Frisk went to Mt. Ebott and fell into the underground. She befriend all of the monsters of the entire underground but some monsters still bullies her but a skeleton named Sans will save her all from that incident
New parts come out slowly
(This is my version of HorrorTale)
Frisk seems to abandon the underground. The monster try to move on but the thought of her being gone isn't a nice one. Years later a human child falls into the hell, Frisk had abandoned.
