This is based on a roleplay with  @FerretFanatic .

No matter which Horror-movie they picked, the gang fell asleep each and every time. They had seen, and done, far worse, so it wasn't easy to scare them. However, due to no need for sleep, Nightmare was still awake, as well as one of his teammates, Killer.

Killer was bored, so he started to tip his fingers on the couch, trying to recreate his own Megalovenia, and failed horribly.

" I swear, sometimes, all of you are little kids, and I'm the father. Killer, help me, please." , Error was unconciously hugging Nightmare, despite his haephophobia. But the King of Fear was really uncomfortable with any form of physical contact, too, since he got bullied as a kid. It's not that easy to forget a few horrible centauries of existence. Thankfully, those times where over now. He had a caring family, which didn't include Dream, even if all of them were crazy. Wasn't he, too ?

Killer noded in approval, standing up in order to drag Red and Horror away, before returning back to the living room.

" Heh. Thanks. But... I'm still trapped. And throwing him off could be dangerous, and I don't want you to get hurt, so that's not an option. " , the Guardian of Negativity trusted his gang, so he wanted to show them that he cared. They held up a somewhat rude relationship as a cover for their real one, so noone would get hurt. Of course, there were people who knew about this, but all of them, even Blue, kept quiet.

Killer laughs at this statement, only replying " Nah, you look comfortable. " , for a second, his blue eyelights were visible, but they quickly disappeared.

" As comfortable as you can be when a glitching mess decided to sleep on your lap and coudle you to death. Error doesn't only have a deep sleep, no, he has a tight grip, too. " , not that it was affecting the goopy skeleton, he had no bones left, so they couldn't be broken. Not anymore at least. Seeing that Killer was the only one awake, the dark twin decided to start a conversation : " So...Anything new ? "

"Not really, life is boring, as usual." ,he hissed knowing that nightmare wouldn't care about what he thinks, glancing at Error, completely jealous.

Now, as a guardian of emotions, Nightmare could read them like a book, so he gave the other a confused look. " If you want to cuddle, too, you'll have to come here. It's not a big deal, I'm apparently a giant tedybear, anyways. " , and with that, the king opened his arms for yet another person he cared about, accidently letting his tentacles mirror the action. Sometimes, it was difficult to control them, especially when he wasn't paying attention. He had to learn that the hard way, it was his first kill, he never meant to end their live, but he was to scared, so he lost control.

Killer blushed, but he walked over anyways, looking down while doing so. After basically hiding himself in Nightmare's lap, he looked up at the other.

" Someone is searching for affection, huh ? It's fine, you deserve it. You went through so much, yet you're still here, alive and well. Every day you survive, each of them is a thropy of bravery. I'm happy to have you here, everyone is. But you shouldn't be jelous. They deserve to live, just like you. They deserve to be loved, even when others hate them. We're one group, one family, and I want you to protect that, alright ? " , Nightmare's voice was soft, but serious, he meant every word. He would never lie to any of them, even if it would cost him his live.

Killer blushed more, even if he was still jealous. He loved his King, even if it was selfish, and he wanted the guardian to be his.

" Hey, are you okay ? You're face is red...Don't you dare make me sick ! " , while last sentence was a joke, it also showed his concern for the small skeleton.He couldn't lose another person, not again. While he was obviously good with negative emotions, he struggeld with positive ones. He could feel them, yes, but he couldn't tell them apart like the negative ones. Though, he was curious, what was Killer feeling right now ? It was probably just happieness about getting his well earned affection, each of then lacked it at some point, and the Embodyment of Negativity was determined to show it towaards them, even if he should be unable to do so.

"I-I'm fine just... I'm not sick..." , the murderus skeleton was stil blushing, and he didn't dare to look up.

" But...your face is still red ? What else could cause this ? " , by now, the leader was really worried, that didn't sound very reasuring. He would get a doctor, but they wouldn't help him, anyways, for he was ' the bad guy' , the villan. And none of them had healing magic, especially not Nightmare himself, so that wasn't an option, either. Should he try kidnapping Blue again ? The little cinnamon roll was a great healer, and the only one who wouldn't refuse to help him or his teammates.

"It's blush, okay. I'm blushing..." , Killer said through his gritted teeth.

Despite not having ears, Nightmare could hear fairly well, so he was suprised by this comment.   " You-What ? I think I read something about this once...Oh, it's from emberrassment, right ? But you aren't embarressed ? And you wouldn't have a reason to be ? " , now, the King of Fear was confused. What was his companion hiding ? Something threaten-No, Killer wouldn't do that, he was just being paranoid again. It was probably nothing important.

"It can be caused by many things. It happens if you are near someone you love, because you don't want to mess up and embarrass yourself even more. " , his cheeks got darker as he spoke.

" Oh ? Who's the lucky guy ? I'm curious now, spill. " , the negative guardian couldn't help but feel a spike of jealousy, even if he didn't know why. There was nothing wrong with Killer liking someone, right ? So why would he feel like this ? Though, it did calm him down that Killer wasn't sick, it got more difficult to borrow Blue from his Universe, since Stretch was always around him.

Kiler flinshed, how was he supposed to explain this ?

" Uhh...Oh god, I messed up, didn't I ? You don't have to tell me, I was simply curious. " , noticing the nervousness, he attempted to solve the problem by trying to give Killer some space, but since Error was still holding onto him, he couldn't really move, so he was kind of helpless. Error. Error was next to Killer. The guardian froze. Killer must be in love with the Destroyer ! Something boiled inside of him, even if it shouldn't, and his tentacles were visibly sharpening once again.

Killer looks at him " No- you didn't ! I was just surprised— Nightmare...."

However, the Lord of Negativity wasn't calming down with that, since Killer was still nervous, and his own jealousy was only growing. " Yes, Killer ? What is your problem ? " , it wasn't meant to sound rude, but he was on edge right now, so he couldn't help it.

Killer looked terrified,he was scared that he did something wrong "You're tentacle..."

" Yes ? What's wrong with them ? They're perfect to throw someone out of a window, you know ? Would you like to try it out ? " , by now, Nightmare was completly lost within his own emotions, so he didn't care at all. After all, his body was made of liquid hatred, it wasn't too dificult to get lost within it.

Killer backed up and climbed over the seats shaking, yes he loved Nightmare, but is terrified of him at the same time.

" Ohh ? NOW the little kid is scared ? You're a pitifull creature, but I won't pity you. Might as well kill you right now, traitor. " , the negative guardian had already sharpened his tentacle far enough to kill the mortal skeleton...

But....he hesitated. Was that really what he wanted ?

Killer wasn't ready, he couldn't build up his magic fast enough, and he had no knives...Was this his end ? He couldn't even put his guard down once?

" Heh. Pathetic, isn't it ? I can't even bring myself to kill you. Well...I'LL GIVE YOU THIRTY SECONDS TO RUN ! " , and with that, he started counting out loudly. He didn't know why he was acting like this, he didn't know what he wanted.

...One...

Killer got up, bolting to his room and hiding within his secret stach of knives, still shaking.

As promised, Nightmare waited in the living room, still counting. Why was he chasing his teammate again ? Oh right, he betrayed him by loving Error. Did he deserve death ? Yes. Would he be able to kill Killer just like that ? ...Yes ?...Should he though ? There were always other people, but Nightmare noticed. He noticed that he loved the murderous skeleton. Shouldn't Killer notice, too ? He should have, but he didn't. And now he was going to pay for that.

...Two...Three...Four...Five....

Killer gripped his head in frustration.

The negative guardian was bored, the seconds were passing ever so slowly. So he started walking in circles, attempting to get rid of his boredom.

...Six...Seven...Eight...Nine...Ten...Eleven...Twelve...Thirteen...Fourteen....Fifteen...

"I love him I do... but why does he want to kill me?!" he whispers, what happened ?

" Dunno. Did you say something wrong ? " , suddenly, Horror appeared out of nowhere, sitting beside Killer

...Sixteen...Seventeen...Eightteen...Nineteen...Twenty...Twentyone...Twentytwo...

...Twentythree...Twentyfour...Twentyfive...

"Horror What the hell ?!"

" Hey, don't blame me, it's really creepy when your boss is walking in circles, grinning insanly and counting out loud. How was I supposed to know that he was chasing you ? " ,Horror defended himself. Indeed, he was shivering. Maybe there were things that could scare a bunch of murderers.

...Twentysix...Twentyseven...Twentyeight...Twentynine...THIRTY

"He's coming, get out! Hurry!"

" Wha-Why ? I thought that we were hiding in here ?! " , Horror yelled, maybe a little too loud.

He finished counting, and he would keep his promise, like every normal Sans would. Though, for some reason, he didn't want this to be unfair, so he wasn't searching for Killers unmistakable aura. However, he got to know his location, anyways, since a loud whisper-screem halled through the hallways.

" WATCH OUT, KILLER, I'M COMING FOR YOU ! "

Killers breath hitched as he grabbed some of the knives.

If you listened closely enough, you could hear Nightmare's footsteps. They were loud within the almost empty hallways, and they were slowly approaching...

...Tap...Tap...Tap...

" I   c a n   s e e  y o u. "

Killer then runs out, not wanting his teammate to get hurt.

" L o o k   w h a t  w e  h a v e  h e r e.....My lovely prey...You shall suffer for making me suffer...N o w : D I E . " , a tentacle shot out, attempting to stab Killer through his soul, but it missed. Attacks were fired, more and more, stronger and stronger. Nightmare's strenght was raising with his anger and Killer's fear.

Killer got out a knife setting it to his own soul, he gasped as it pressed into his soul "Nightmare I was trying to say I love you...."

The attacking one stared at Killer in disbelief, his attacks had stopped, too. " You-What ? " Another tentacle reached out, grabbing the knife. Now they stood there, Nightmare holding Killers knife to the mortal's soul, ready to shatter it at any moment. One wrong step, and the eyeless skeleton would die.

"I love you Nightmare I always have. I don't know what pushed you to want to kill me... but look you can..."

" You love...ME ? Not Error ? " , the King was slightly confused, what brought this up? Why would Kiler love such a cruel monster ? He tried to kill him ! Or was it just an attempt of trying to survive ? No, Killer had clearly been feeling something positive the whole time. Could it really be love ? Still unsure, Nightmare drew the knife back, even though his tentacles were still sharpened.

"Yes I love you. Why would I love Error?!"

" You-Oh." , finally relaxing his stance, the Guardian of Negativity dropped the knife, and started walking over to the other skeleton. In an attempt to redeem himself, he hugged his crush.

" I'm sorry...I love you, too..."

Relieved, Killer's tears started falling, he had been stressed beyond bearable amounts.
