Broken Souls 1 - Sans × Monster!Reader COMPLETE by NeonVixen
13 parts Complete
Instead of you being a human, you're a monster in the Underground. I will continue to go back and edit or merge parts until I have completed the story. Parts that I am actively working on will be labeled "[under editing]" Also, art cover is an action figure off of fangamer.com. they have more action figure characters that are so cute. I am not affiliated in any way with fangamer.com. This is my 1st story in a VERY long time. I like to do things a little different as far as reader inserts go. 1. Instead of Y/N for your name, I use _______. Why? Because when I'm reading a story and read Y/N I think Y/N and then have to remember the name of the character I've made in my head, where as if I see _____, I immediately replace it with the name because there is no word for me to read. Love it or hate it, comment. I can be persuaded if the masses disagree. 2. I don't do H/C, E/C, etc., because it does the same thing that Y/N does for me. Instead, I will be as vague as I can on insert character descriptions giving the reader more freedom to imagine what they look like without forcing it down their throats. 3. For undertale specifically, I am more inclined to make monster!reader inserts, because that makes more sense to me. This will not always be the case. If the masses prefers human!reader inserts, comment so that I may be persuaded to do so. Also, feel free to ask for requests. The more requests I get, the more inclined I will be to do more stories. They don't just have to be undertale related. I will give you credit for any requests at the beginning of the story.

It wasn't your fault you were in this situation. It just happened at random chance, now you were stuck in a loop. A endless repetitive loop of death and obsessive love. He wanted to keep you forever, and if it meant becoming a monster worse than anything, he'd be okay with it. After all, he LOVED you~ Heyyyyy Something I came up with, don't know if ill be doing smut with it or not, buuut hey, it's DT Sans, people seem to like him, updates will be slow, but please be patient!! :P Besides I don't think there's enough love for DT. Lol no regrets writing this whatsoever since DT Sans is bae for me ;) (June 5th: Lies, I have a new bae now ;-; and it's Horror Sans) Btw if gore and such makes you uncomfortable, I'm sorry my dude, but that's whats gonna be in this book. And some heavy angst between you the reader and Sans of course.. But of course budding romance!!! (I think..?) Verrrrry verrrrryyyy slow burn Tags will be added along the way
