I got some Swightblue for yalls
Nightmare and Blue had never been particularly close. In fact, they seemed to have an unspoken law to leave each other alone unless they absolutely had to deal with the other. So it was definitely a surprise to those who knew them (And even themselves) when they started getting much closer seemingly overnight. The funny thing is, it was overnight, or rather, over many nights. Many nights of secret rendezvous and poorly hidden affection towards the other. If you want to understand how these two got closer so close, you'd need to go all the way back to when they first worked together towards a common goal.
Nightmare ran down the halls as quickly yet quietly as he could, trying his hardest to muffle the slap of his shoes against the tiled floor. He was expecting to run into a guard or, if his luck was truly terrible, Dream. However, luck was on his side for once and he encountered no one. Well, almost no one. When he finally reached Dreams office (The location of which he'd learned through many trips through JR), he was surprised to see a solitary blue figure crouched in front of the door.
Blue was currently picking the lock of Dreams office which was quite easy with all his practice over the years. He quietly hummed a song as he worked, tense but at the same time very calm. He'd done this whole song and dance more times than he could remember. Dream would find something on Blues many... Less than legal activities, Blue would break into Dreams office and destroy the evidence, Dream would have to restart with no further evidence of the others crimes. Blue smiled at the thought of how angry and confused Dream would be when he finally woke up. Poor Angel Boy won't know what hit him. He thought, grinning. After a few more seconds, a quiet "Click" echoed through the silent halls and Blues smile only widened. He stood up and was about to enter when he heard someone clear their throat behind him.
He spun around, fearing that he had been caught, but was slightly relieved to see that it was just Nightmare. They stared at each other for a moment before Blue broke the tense silence.
"What are you doing here?" He asked, quickly masking his previous surprise.
Nightmare raised an eyebrow, "I could ask you the same question."
Blue chuckled, "Touche." he sighed, picking a stray string off of his scarf, "Well, I'm here because Dream has some rather incriminating evidence in there against me and, well, I'm guessing you can figure out the rest."
"Still part of some illegal drug ring or something?"
"No, just trying to make a living in a very cruel world."
Nightmare scanned Blues face for any sign of lies or malice and even by scanning his emotions, he couldn't find any trace of deception.
Blue scoffed, snapping Nightmare out of his trance, "Well, I can see you definitely don't trust me."
"Have you given me any reason to trust you in the first place?" Nightmare snapped.
"We share a common enemy and, as the phrase goes, "The enemy of my enemy is my friend."
"You wish." Nightmare retorted then hesitated before sighing, "Y'know what? I don't have time to argue with you over this. How about we just agree not to mess with each other and get on with our lives, deal?"
Surprisingly, that wasn't the end of their meetings. At first, it was through accident when they ran into each other in the castle again. Though over time, the confrontations began to become more intentional. Although neither would ever admit it, they began to enjoy being around the other. Maybe it was the adrenaline in those tense moments or blind stupidity, but there was something that drew them to the other. No one knew about this other than them. It was easy for Blue since no one was really there to ask where he went all the time, but things were a bit more difficult for Nightmare.
"Where do you keep going?" Cross asked.
”Yeah," Error butted in, "I get that you spend a bunch of time bothering Dream but you've been gone a lot more often. So, mind telling us what you're doing all the time?"
Nightmare began to panic, fearing how his friends would react to the knowledge that he was spending time with Blue, someone they weren't supposed to trust.
"Training!" He blurted out, surprising all of them.
Cross looked at him skeptically, "Training?"
Nightmare hesitated before nodding, "Y-yeah! I was worried that I was getting too relaxed and weak so I decided to make sure I'm still at peak performance!"
They eventually let the topic go and Nightmare had never been more glad that he and Dream were the only two who could sense emotions.
"You're later than usual my Purple Prince."
Nightmare sighed, "What have I said about that damn nickname?"
Blue chuckled and hung upside down from the rafters he was previously sitting in, "You've said you hated it, but I for one certainly enjoy seeing how flustered you get when I use it."
Nightmare scowled at the feeling of his cheeks heating up, "Just shut up before I sell you out to Dream or something."
"I highly doubt that partner." Blue said, jumping down.
Nightmare fake gagged, "Eww, that's even worse."
Blue leaned down so they were eye level and just inches apart, "Purple Prince it is then~"
Nightmare couldn't help the blush that blazed across his cheeks at Blues tone and how close they were.
It took him a moment before he snapped back to reality and shoved Blue away, "Nooooo more of that."
Blue snickered, grinning at him, "Oh c'mon Nighty, I can't sense emotions like you and I can still tell that you weren't exactly opposed to that~"
Nightmare wanted to die at this rate, "Shut up already." he growled, turning down the hallway and walking off briskly.
Blue quickly caught up, practically skipping up behind Nightmare, "My my, never took you for the tsundere type."
"If you don't stop talking I'm going to find a way to make you shut up for once."
The taller male danced around Nightmare and stopped in front of him, once again leaving their faces just inches apart, "And how would you plan to do that my Purple Prince~?"
Nightmare finally had enough and shoved Blue up against the wall. Blue was surprised and was about to make another witty comment before the other quickly smashed their lips together. Both were fairly surprised by the sudden action but didn't entirely care at this point. The kiss began escalating and they only stopped when Nightmare pulled away slightly.
"We're so going to get caught." He mumbled.
Blue smirked, leaning forward again, "I don't think you're really worried about that."
Needless to say, Blue was right.
