Murder!Sans x Gloomy

So... as you can imagine, this is just another fangirl fanfiction, this is a self insert/selfship story so if you don't like this type of content i'd suggest you to stop reading, anyways i will try to make Murder/Dust Sans as close to the canon as possible.
Another disclaimer i'd like to add is that english is not my first language so i apologize if there's some grammar or writing mistakes, i'm still learning and feeding my vocabulary.
The art on the Cover belongs to my friend @eclipsaghost on instagram, Thanks again Eclipsa for such an amazing art of me and Dusty!! <3
Murder!Sans is not my character, it belongs to ask-dusttale on tumblr, all credits of this character to them!
Also You'll need some context about undertale and dusttale lore to properly understand this fanfiction, so i recommend you to research about it if you don't quite know about it, but i'll be glad to answer any question or clarify any reference! without anything else to say, enjoy this delulu thingy ;)
