Yan!Nightmare x Reader (DISCONTINUED)

Ch.10 Horror

After awhile Nightmare falls asleep, cuddling a sleeping Y/N. However, none of them are aware that their dear dreamcatcher is going to go on another adventure soon. Another portal opens up under Y/N and she falls through it and falls in the snow, still asleep. There is a crunch of snow as footsteps approach Y/N, and then they stop, observing her to see if she is a threat. The owner of the footsteps hum as they realize that Y/N is a LV1, and seems pretty weak. They debate on waking her up and killing her or killing her in her sleep. They decide to go with option c, and let her die in the cold as they walk away. The owner of the footsteps is quickly killed by bones and something wakes Y/N up. Y/N wakes up and looks around confused.
"H-huh? W-where did i-i end u-up this t-time?" Y/N asked, talking to no one in particular 
"Dunno. Why were ya asleep in the snow? Do ya wanna be my next meal or something?" A skeleton with a hole in his skull said
Y/N, seeing the hole in his skull, gasped in surprise and went to go and try to heal him. The skeleton was surprised and moved away a bit from Y/N.
"Sorry, but ya can't heal this" the skeleton said
Y/N frowned and tried to heal more, but the skeleton just took her hands and moved them away.
"Ya can't heal me" the skeleton said, once more
"B-but, I g-got to t-try!" Y/N said, determined 
The skeleton sighed and looked at you.
"What's your name birdie?" The skeleton asked
"I-im Y/N, a-and you a-are" Y/N asked
"Names Horror sans, but just call me Horror" he replied

~~~Timeskip over~~~
You gave Horror the room with the axe on it, and started to make dinner for everyone, wanting everyone to eat. You decide on making some soup with some bread and look for the materials to make it and look to see if its fresh. You smile when you see it is fresh food and you check the pots and pans to see if they are clean. You smile more when you see they are.
"Boss thought that you might've wanted to cook, so he got fresh supplies and threw out the old ones" Dust said, leaning against the wall
"T-thank you f-for telling m-me Dust" Y/N says with a smile
Dust nods and walks to the living room, while Y/N starts working on the soup and bread. Y/N hums as she cooks, not noticing Horror watching them as they work. Horror walks over and taps the counter. Y/N looks at him and smiles.
"H-hello Horror. D-do you n-need something?" Y/N asks
"...what are you making?.." Horror asks
"S-soup and b-bread. Why?" You ask
"....curious….do you need any help?..." he asked
"N-no thank y-you, but t-thanks for a-asking" Y/N says, smiling
Horror nods and watches you cook. You hum and soon, dinner is ready. You go to set the plates, but Horror takes them out of your hand and set them on the dining room table. You thank him and give everyone their food, and then call Nightmare, Error, and Dust down for dinner. They teleport in and smile when they see the food. Everyone sits down and starts to eat.
~~~mini Timeskip bc author is hungry~~~
At the current moment, Y/N is asleep on the couch and cuddling Nootmare while Horror watches. Nightmare hums and looks at Horror.
"What made you decide to join?" Nightmare asked
"....I don't want to be alone anymore and I don't want to die…." Horror said
Nightmare nodded and hummed.
"Is that all?" He asked with a knowing look
Horror hesitated, thinking it over.
"....Y/N is kind and nice to me…." Horror answered 
Nightmare nodded and hugged Y/N closer to him, giving a kiss to her forehead. Y/N smiled and purred in sleep, wing curling around him peacefully.
