Nightmare was looking for a maid to help around the castle when he noticed a girl with H/c hair,E/c eyes, a s/f/c long sleeved dress on, with mint green leggings on as well. Nightmare teleported the girl to the castle leaving her confused she looked around her surroundings to see three Sanses, Horror,Dust and Killer. She knew them but didn't like them in fact she was their enemy and they wanted her out of the castle but what they didn't know was that she was gonna stay there for a while because she was Nightmare's maid but she didn't want to get close to anyone. So Y/n after she became Nightmare's maid she did her work and chores but would then go to her room and play on her phone or draw to be honest she didn't really trust Nightmare because he was the one giving her nightmares and bad dreams. Noticing that Y/n would always go to her room after doing her chores he followed her to see her singing "Forever is a long time, but I wouldn't mind spending it by your side" he noticed a smile on her face as she kept singing only to stop because she had to do more chores. Y/n grabbed her phone and played the song she was singing and plugged in her earbuds dancing to her music giggling to herself Nightmare kept an eye on her to make sure Killer or the other evil Sans wouldn't try to hurt her but when he went to get a drink he heard a scream. Running back he saw her about to get killed by Horror he sighed tired of always having to save her from one of them. He pulled Horror away with his magic noticing Y/n starting to sob he chuckled softly before walking away letting her sob silently. Y/n heard his chuckle and instantly knew that it was him that saved her happiness ran through her eyes as she tackled Nightmare into a hug after she caught up to him only to get pushed off him receiving a glare she ran off starting to cry again all she wanted to do was thank him for saving her and he just pushes her away? to Y/n in her mind it was rude but she expected it because he was evil after all. She decided to leave him alone and try again the next day or when he gave her a nightmare.
-The next day after everyone woke up- Y/n yawned and stretched her legs and back popped when she walked yawning again trying to get the sleepiness out of her she drank some water and poured water on her face which woke her up after she got herself fully awake she knocked on the others' doors telling them breakfast is ready "Guys breakfast is ready!" they came down in a flash they secretly all enjoyed her cooking including Nightmare and they all enjoyed her being there as well but they weren't gonna say that to her out loud. Y/n did the dishes when everyone was done eating when she felt arms pull her into a hug it was Nightmare she turned to face him smiling as she kissed his cheek before pulling away and continuing to do the dishes when she was done she was pulled over to the couch by Nightmare he cuddled her "My savior" she said cuddling Nightmare back.
