Narrator's POV
Nightmare walked into his castle, it's been two months since (y/n) left with Ink and the others. Those two months have been hell, in a way.
Nightmare can't help but feel an empty feeling in his chest area, right where his heart was meant to be. He can't help but feel lonely as he walked through the empty halls of his castle. He can't place a finger on what caused the sudden change. He was fine before (y/n) jumped into his life (which he accepted with open arms).
He doesn't know what causes this but he knows (y/n) can stop it, he doesn't know how, but he just knows!
So, that's why he decided to kidnap her.
~
(Y/n) was, in simple terms, depressed. Not the 'contemplating - suicide' depressed, but depressed none the less. She could not deny it was all Nightmare's fault.
Although she was glad she met the skeleton, she couldn't help but get sad at her own thoughts. Yes, he's an evil skeleton! Yes, he's supposed to be arch enemies with Dream! But God dammit, she wanted that skeleton!
So, that's why she was going to sneak out to meet with Nightmare.
~
Nightmare opened a portal to the void Ink and Dream currently used as a hiding place for (y/n). They both feared that Nightmare will take her again. And also that she might try something.
(Y/n) tip toed stealthy out of the actually large house that Ink created. She let out a quiet hiss as she almost tripped right before making it completely out of the building.
Nightmare walked without a care, you know, for a void, it looks pretty full of life. He walked past the numerous trees and bushes, using his hand to live a branch or two out of the way. He walked for a few more minutes untill he spotted a house. A large house, dare he add.
(Y/n), on the other hand, was trying to be as quiet as possible. She tried her hardest to make no sound, cringing inwardly when she did. Once (y/n) was out of range of the house, she began running. She wasn't sure how exactly she'll get out of here, but she's hopping to find one of Ink's portals left open.
Nightmare walked slowly, carefully looking at the area.
(Y/n) ran as fast as she could, but also scouting the place for an open portal.
Nightmare walked.
(Y/n) ran.
They bumped into each other.
(Y/n) stared into his eye sockets with shock and surprise before her face morphed into a large grin. She jumped into arms, burying her face in the crook of his neck.
Nightmare looked at the girl. He couldn't help but letting a stupid lookibg grin from crashing his features. His face heated up as (y/n) buried her face in the crook of his neck.
They separated and looked at each other. Suddenly becoming aware of their position, (y/n) awkwardly shuffled out of his arms.
"Nighty~" she cooed. Nightmare let out a groan, rolling his eyes in a friendly manner. "How many times do I have to tell you, don't call me that," he secretly liked it.
(Y/n) giggled at his response. She took his arm in hers, intertwining their fingers with a small blush on her face. Nightmare stuttered as he felt the soft feeling on her hands. She giggled lightly, "I'm assuming you came all this way for me, So, let's go!"
~
"Ink have you seen (y/n)?" The bright skeleton know as Dream asked his companion. The two just got back from chasing Error, Ink's secret crush, Dream claims.
The artist popped his head out of a corner and looked the shorter dead in the eye, "No... you don't think we left a portal open do you?"
"I checked twice, pretty sure not," Dream responded.
The two looked at each other for a few seconds, suddenly, something clicked.
~
(Y/n) laughed heartedly as Nightmare continued to tell her stories of his adventures as they sat in the space universe.
"Stop laughing! Error leaving me and going for Ink is not funny!" He huffed and turned his head away from the female.
"Those two are so gay for each other," (y/n) wiped the tears forming in the corner of her eyes. Nightmare agreed with her and ranted on about how they should just get together or something.
(Y/n) laughed some more, more tears forming at the corner of her eyes. Before she could wipe them though, she felt a bony finger do it for her.
She looked into the sockets that stared at her lovingly, she smiled at him, closed her eyes and leaned into his touch. She shifted closer to him. Nightmare continued to caress her face, he smiled lovingly.
They both subconsciously leaned in to one another. Nighmare's other hand reached the other side of (y/n)'s face, making him cup her cheeks. She looked into his sockets with a longing still smiling.
The gap was drawing thin, only a few centimetres away. Nightmare could now feel (y/n)'s hot breaths on his face. He looked up to ask for permission and was met with a smoking sight. (Y/n)'s eyes were half closed, looking directly at the skeleton's grin, her face was a deep shade of red, her lips slightly parted with hot, shacky breaths hitting his face.
Nightmare leaned in more same with (y/n). The gap between them closed. Their mouths met in a passionate dance. They moved in sync, Nightmare's hands moving to (y/n)'s waist and her hand moved to Nightmare's neck.
Nightmare's ecto tongue formed, he licked her bottom lip, asking for entrance. She granted it with a moan. Their tongues moved in sync, complete harmony and complete love.
Ink and Dream barged through a portal yelling for Nightmare to stop whatever he was doing to their friend. They stopped yelling as they say the two mouths still connected.
Nightmare and (y/n) suddenly became aware of what they were doing, they separated with a string of saliva still connecting them. (Y/n) wiped the drool at the corner of her lips and looked at Dream and Ink standing wide eyed.
(Y/n) looked at the two males before sighing, "Look, you guys can't keep me away from hanging out with Nightmare. I really enjoy his company and.... I think he does too." She looked at the skeleton expectantly, intertwining their fingers as a show of her affection for the skeleton by her side.
Ink and Dream looked at each other in shock, they huddled up and had a quiet conversation.
Ink looked back at the two holding hands, "Okay Nightmare, Dream and I have decided t-" he was interrupted by yelling from an enraged skeleton.
"Touch my baby girl wrongly, I dare you!!!!" He exclaimed having to be held back by Ink. Nightmare rolled his eyes at this and waved it off, "Yeah yeah, I promise"
Dream calmed down and looked at (y/n) with a smile, "As long as you want this, I'll... tolerate it."
(Y/n) ran up to the two and gave then the biggest hug she could. She kept thanking them, squeezing them with all her might.
"Ok, that's enough.... can't breathe."
She released the two from her monstrous hug before running to her unofficial boyfriend.
After placing more threats on Nightmare Ink and Dream finally left, leaving the two lovers alone.
Nightmare looked at (y/n) with a smug smirk, "You like me that much, huh?" He was greeted with a light punch on the arm, "Oh shush you."
The two looked in each other's eyes, leaning in for another kiss. They separated a few seconds after.
"Wanna make this official?" Nightmare asked, breaking the comfortable silence.
"Thought you'd never ask!" (Y/n) leaped into his arms and they passionately kissed.
Few days later, everyone knew that the two were an item. Turns out, a lot of people shipped them.
Bonus
"Well, I knew they'd be an item" Frisk said out of the blue. Her and Sans were sitting and chilling in the original skelebros house.
"You know what's next?" She asked her lovely boyfriend.
"ErrorInk~"
