One day a girl named Frisk fell down a hole she got knocked out from the fall and woke up in a room with a girl sitting next to her.

It's been four long years since Frisk saved Chara. Chara had tried to thank the child by helping them rid and keep away the Anti-Monster cult members, but it didn't seem enough. Frisk finds a way to thank them in return for not trying to kill anyone these past four years by giving them a gift they would never forget. There will be hints of sin. If the sin hasn't been fulfilled, that is. <: Created: March 15th, 2016. Second book: Determination Underfell AU: Save art by dreamy94 on tumblr

This is total charisk sin. I'm so sorry mother. ( yea no I'm totally not) (cover art is not mine!) [i do not own undertale or the characters in this fic]

Poop

!!!!!!!!!THIS IS IN THE WORKS OF BEING REWRITTEN!!!!!!!!!!! Best title ever. Ok, so basically this is a fanfic of Charisk, or... Chara X Frisk. And so just to roughly skim the top of what this is, it'll just be like... What they're doing how it started ect. Some chapters will have "Part [insert number here]" that basically just means there's going to be another part to this chapter. Also, they're both 16. Frisk is 7 months younger than Chara. Got it down to a science, heh. I will warn kissing will be added, if you don't like kissing then you're going to have a hard time reading some of the chapters, hue. They're both girls, as far as what I wrote. Sorry if you think they are different genders. Ah, also, I will warn my terrible spelling mistakes! Anyways, hope you enjoy this.
