Murderous lovers dust sans x reader

she never left his side

dust pov

I'm thinking over my head again. y/n keeps on hiding themselves and it's annoying me, and nightmare cause she too beautiful. "Dust if you love them then why don't you go find them before they do something stupid" nightmare said and then omnipotent sans came into the room. "Has anyone seen Luna?" he said but no one said anything which made him worry. those two are best friends but I'm thinking Luna is in the garden thinking of horror. 

" She is thinking of horror?" nightmare said and i said "she hasn't left the garden since horror died." and when I said that it took me back to that day, the day he was going to confess on how much he loved her.

-----flashback-----

Luna pov

i was looking at the stars in outertale because they are just so lovely. "Hey lu" horror said and i jumped and turned around he was blushing while holding black flowers. "Can I ask you something Luna?" he said, and I nodded "i just want to say i love you." horror said and gave the flowers to me and then error 404 came up behind him and tried to attack horror but luckily, he dogged it.

"Well as I told everyone in the bad sanses to leave my baby alone." error 404 said but last time i checked im with horror now and not 404 after all he is a bastard. "Since when was she yours 404?" horror said and error came by "hey horror what's going on here?" error said and horror just looked at him and error knew. "Look 404 just leave this place is a calm space and not made for fights ok." error said but 404 refused and took horror's soul and next thing me and error knew was we heard his soul crack. 

we looked Closey to the strings and the soul that's in it. it's slowly dying thanks to 404 and horror's body is stuck on the rocks. "404! stop you're killing him!" i said and he told me this "come back to me and this will never happen got it?" but i happily refused his offer and got omnipotent to help me and error. "William enough you caused too much damage to her and everyone else." he said but as error 404 is the older brother he said "no omni i need her back into my life i can't lose her again." 

error tries to sneak closer to horror's soul to save horror but sadly it didn't work as he thought. 404's strings are much stronger than his. "Shit I'm sorry horror." error said and horror said "i-it's okay error you did try at least and goodbye." and those were his final words. me, error and omnipotent were just standing there looking hopeless. horror's body turning into the thing we always feared the most, dust.  i was pissed and i was bloodthirsty. i summoned my scythe and rushed towards 404 and sliced him but it only left him with a huge cut on his stomach.

"HOW DARE YOU KILL HORROR! YOU BASTARD!" i yelled and tears were forming into my eyes and 404 said " none of this would have happened if you came back to me dear." and with that he left and i fell to the ground but luckily error caught me and said, "don't worry we will get horror's revenge that's a promise."

omnipotent's  Pov

i feel really bad for Luna. had fell cheat on her and then horror got killed by William's hands. why does this always happen to every goddess or God of eternity? and yet i was the only one who didn't do anything to help her but she told me not to do anything. then i see her in the garden looking at horror's grave.

"you know horror would want you to do something happy right?" i said and she said, "not this time omni im just going to stay here and nothing more." i sighed deeply i want her to be happy again but this not the way to go. "look you're not thinking of committing suicide are you?" i said and she got up turned around to look at me and said "if i want to see him again then yes." then i slapped her on the face and she widened her eyes and said "what the fuck was that for?!" and i said "you're gonna go to hell if you do that dumbass and i know horror wouldn't want you to think such thoughts." and i left her to think about her actions.
