“Hey there little girl.” A tall man walked up to you slowly. His eyes had a glint in them you couldn’t quite place.
“Um hi. . .?” You asked carefully. Holding your hands to your chest, where was mother? And who was this stranger?
“What are you doing all alone. . .?” Bending down beside you to be at your level. His hand on one of his knees.
“Im waiting for my mommy. . .” You said truthfully. She had told you not to talk to strangers, but surely this question wouldn’t hurt to answer right. . ?
He tilts his head a bit. “Oh. .? And how old are you?” He asks, theres something about his smile, it’s crooked and off putting.
“Im. . nine. . .” Nervously you back up a bit, you really wanted this stranger to leave you alone you got a bad vibe from him. .
“Well aren’t you such a pretty little girl~” He suddenly grabs your chin caressing it gently.
“Wh. . What?” You pull away from him, confused and creeped out.
“Say sexy~ do you wanna come wait for your mommy with me~? We could have some. . . Hehe. . Fun~” he said with a hunger in his eyes. As he mentally undressed you.
“I. . I don’t know. . She said not to talk to strangers. . .” You backed away from him slowly. Eager to get away to the warm and safe arms of your loving mother.
“Oh come on! I’m not a stranger! You can call me daddy~ and we could have some fun!” He grabbed your waist and held it tightly.
“Stop! Stop! Let go of me!” You fought to get out of his grip. Something told you this wouldn’t be fun.
“Now, now, pet, don’t be like that~” he grabbed your wrist, stood up and started dragging you away.
“Help!! Help! Someone help me!!” You screamed and kicked.
B u t n o b o d y c a m e.
Gasping for air, you woke up with a jolt, sitting up in your bed.
Yikes. That dream again? You sigh. . Slowly getting up and stretching you look at your phone, shit you overslept. Quickly getting out of bed, you ran to your closet changing into your work clothes, office jobs wait for nobody after all.
Quickly walking to your bathroom, you did your business, brushed your hair and teeth, before running down the stairs.
You stopped dead in your tracks, there laying on the couch was none other than Killer.
Killer. Hoooo boy Killer. . . A huge thorn in your side, ever since you met him he’d been. . . Flirty.
You hated flirtatious people, it always made you so uncomfortable and reminded you of. .
Of. . .
“Hey sexy~” He had called you. . So many times. .
“Show of girl~” That cab driver said to you when you tried to go clubbing once.
“Wiiwo~” A guy whistle to you on the street when you were 14.
“Hey pretty girl~” Your first Boyfriend mimicked the sounds he made. .
“Hey princess wanna have some fun tonight~?” You were drunk and they tried to drag you to there car. . .
“Hi my names Killer but you can call me yours~ wanna head to my place and have some fun~?” Thats how he chose to introduce himself. Sure it ended up just being you and his buddies playing video games. . But he still. . .
You started to shake a little remembering your dream, flicking it out of your head you hid your nerves and walked over to Killer. You were gonna confront him this time, you were gonna! You had to. You couldn’t be a doormat forever.
Killer smirked when he saw your pissy face walk over to him. This asshole!
“Now what do i owe the pleasure?” He mocked politeness. Even faux bowing for you.
You put your hands on your hips. ‘Stop flirting with me’ echoed through your head, you had already asked him to stop several times but he never took you seriously before. Always making up excusing or just flat out ignoring you.
You were gonna make him take you seriously this time, this time he’d see!
“I- i- . . . Um. .” Fuck where was it? you were so driven! So mad! Why was it failing on your lips? Maybe start with something easier?
He looked at you expectantly. . You felt your stomach turn.
“I. . .” Shaking a little. “Why are you in my house. . .?”
“Oh is that all! Here i thought you were mad at me! Hahaha!” He just laughed and laughed at you, slapping his leg as he sat up. The nerve of this guy. .
“Look princess~” you shivered at the nickname, he seemed to perk up at this. “Princess, princess, princess~” he purred reviling in the way your eyes closed shut and your hands trembled. Killer didn’t know why this got to you so much, but man was it funny seeing you squirm.
“I simply wanted to see my precious beloved bestie at work today! But atlas you weren’t there!” He said over dramatically, like it was your fault for not showing up for him.
Only one thought came to your mind. “Are you stalking me?” You said apprehensively, standing completely still your mind racing. Killer knew where you worked, he had shown up before to pick you up and take you home. But following you to work? That was new.
Your work didn’t allow you to invite friends over. Why was he there looking for you?
Killers eyes widened at this. And for a moment it almost looked like he was scared.
“Oh heavens no! Haha, why would you think that? I was just- wanting to see you during your lunch break!”
It was almost 11am. Work started at 9. Your lunch break was at 12. You knew he was lying to you.
Killer smiled at you sweetly, to sweetly, what was he hiding, what had he done. This guy was known to pull pranks and cause chaos, his friends had warned you about him, you had only known him for 2 months yet he seemed to love bothering you.
“Anyways doll~ since you’re not at work why don’t you come over here and we can have some. Fun~?” He sing songed holding something up, but you couldn’t see it. No you were too busy with something else. The word echoed throughout your head.
Fun
Fun
FUN
F U N
F U N~
Stop. Make it stop. Make him stop! You don’t wanna. You don’t wanna! Clutching your head for a moment, you ran over to the door.
Killer looked up at you confused. And followed you to the door cautiously.
“Whats wrong Sweetheart?” He put a hand on your shoulder. Looking at you like you were the one going crazy. Ha!
“Get off me. I don’t wanna see you right now.” You slap his hand away, opening the door.
“Hey now! Im just a friendly guy! Come on sexy I’m just checking in.”
There was a newspaper on the porch of your house, picking it up you stared as you registered his worlds. “Stop.” Came out of your mouth, like a thousand times before.
“Aw come on dolly I’m just tryna see if you’re okay! You didn’t show up to work, you slept in and now you’re all angry for some reason! Just wanna know whats up pretty girl!”
You started breathing heavily. If he didn’t stop. If he didn’t. You told him to stop. Why wasn’t he stopping.
You clutched the newspaper as hard as you could.
“Stop. .” This was your final warning.
Slap him.
Slap him.
Slap him.
Putting an arm around your waste.
Slap that bitch.
Slap that bitch.
Slap that bitch.
“Come on princess you know you wanna tell me whats wrong~ we can have some fun today just relax you and me-“
SLAP!!
You quickly turned around and bitch slapped Killer in the face with the newspaper. It was so hard it left a mark on his face and left him staggering back Reeling in shock, letting go of you completely.
. . . . .
It was silent for a moment as you both registered what you had done. You quickly dropped the newspaper in shock, your hands shaking, your breathing funny. You had just fucked up badly. He was gonna hurt you know, for real this time. Fuck.
Killer took a hand to the bruise on his face, staring emptily at nothing. “What. . . Was that?” He asked slowly still in shock. . But he almost sounded angry? “What. Was that!?” He demeaned to know when you didn’t answer.
“I. . .i . . You didnt stop when i asked you to!” You snapped back.
“Excuse me!? I was checking in on you-“ killer dropped his hand from his face making a fist.
“Not the fucking checking in.” You pinch the bridge of your nose anger rising. “The flirting!! Ive asked you to stop several times Killer and you NEVER DO!” You raised your arm in the air for emphasis.
Killer stopped and stared at you. “You never told me why! I thought we were just being playful- you were being hard to get-“ he started to make excuses. The god damn excuses every damn fuck boy makes.
“PLAYING HARD TO GET!? ARE YOU FUCKING KIDDING ME RIGHT NOW!?” You were seething, you could only see red. The red of his stupid fucked up soul changing to a glitchy target. “IM NOT PLAYING HARD TO GET!”
“THEN WHAT ARE YOU DOING!? I CANT UNDERSTAND WHY YOUR NOT HAVING FUN IF YOU DON’T TELL ME!!”
Fun. Fun. Fun. It’s always about fun. “WELL I DON’T WANNA HAVE FUN WITH YOU!! I DON’T WANNA HAVE FUN WITH ANYONE!!!” You clutch at your sides bringing your head down to make yourself smaller.
Killer looked confused. You didn’t wanna have fun with him? did you not wanna be his friend? Anyones friend?
He felt his soul sink.
Did she secretly hate him this whole time? How could he have missed that? He thought he was good at reading people. . . How could he be so piss poor at understanding this situation?
“You. . . You don’t wanna have fun with me. . ?” Killer was reeling. Had all of this friendship been a lie. . ?
“NO KILLER I DON’T WANNA HAVE SEX WITH YOU!!” You screamed out, not caring the door was open or that the neighbours could potentially hear you.
“Wha- huh???” Killer blushed heavily. “Im not asking you for sex???” He was baffled. “Why would you-“
“Why!? WHY!? You’re seriously asking me why!? god your so demanding Killer!!” You puffed your arms out to your sides going straight behind you. “Fine. Fine! FINE!!! You really wanna know why!?”
Killer nods.
“Cause i was sexually assaulted when i was a child thats why!” You forced out, quieter than before, like you were choking on your own words.
Everything went quiet. Killers soul turned into an upside down heart and a white eye light appeared in one of his eye sockets.
What.
What the fuck.
Killer had no idea, genuinely no clue.
He didn’t. . . He didn’t mean to make you feel like he was trying to force you to have sex.
“I- i didnt-“ Killer tried to step closer to you.
“Get out.” You stepped back.
“Im im sorry-“ he stopped moving.
“GET OUT-“
“I-“
“GET OUT OF MY HOUSE!!” You went over to Killer and grabbed him, dragging him to the front door and pushing him down the stairs, before slamming it locked shut.
You slid down the door into a seated position and sobbed. You really didn’t wanna have this fight with Killer.
Killer stood in front of the door just staring agape. He wasn’t sure what to do anymore. He had accidentally really hurt your feelings. Fuck. Fuck!
He shortcut away to his shared home with Dust and Horror. Dust was sitting on the couch watching tv, trying to relax after a long stressful day at work, Horror was in the kitchen making lunch.
The door suddenly slammed open causing Dust to jolt upwards into a seated position summoning a bone ready for battl- oh wait its just Killer never mind. Dissipating the bone, he relaxed a little.
“Dusstttt i fuckkkedd everythinggg uppp” Killer whinned like he was about to start crying, Dust knew he wouldn’t tho.
“Does it involve me. . ?” He asked seriously. If Killer had fucked up their residency he was going to kill him.
“. . . Noo?” Killer sounded unsure.
“Then suffer in silence.” Dust spat out unamused. Killer could deal with his own problems for all he cared.
“Dussst! Come onnn!” Killer whined again. “Horror tell Dust to help me-“
“Go help yourself.” Horror snapped. “Leave Dust alone. If it doesn’t involve us then we’re not gonna help you.”
“Jeez you guys are in a bad mood what did i ever do to you?” Killer put his hands on his hips.
“You want the long answer or the short answer?” Dust said plainly, lying back down onto the couch.
“Gasp! I never. I cannot believe my too besties wouldn’t help me out. Fine then I’ll take my business else where!” Killer walked out the door and slammed it shut.
“Oh good heavens he’s gone.” Horror said as he got back to lunch.
Killer shortcuts to Cross’s place next.
Cross was hanging out with some friends when Killer started shouting for his attention. “Crossy! Hey! Hey crossy!” Killer was hopping on one foot waving his hands in the air.
When Cross notices Killer he cant help but sigh. “Oh dear god. Hang on a second Alphys, i gotta go deal with the trash.”
“Good luck.” Alphys said back to him as she watched him walk towards Killer.
“Sigh what do you want Killer?” Cross said as he got closer to Killz.
“Hi Crossy! I um. Need your help? i kinda fucked up-“ Killer started.
“Not helping you, go deal with your own shit yourself.” Cross quickly turned heal and started walking away.
“Wha- hey!! Whats with everyone hating on me today!?”
“Do you really wanna know why?” Cross asked.
“Yeah!” Killer said.
“It’s cause you’re an annoying piece of shit. Leave me alone Killz.” And he shortcut away, leaving Killer all alone again.
Was he really that annoying? Was that why you hated him? Is that why he fucked up so badly? Was it just in his nature?
Haha. It must be. .
Laying down in a random au, Killer just laid there for a while. He hardly noticed when Color laid down beside him.
“Hey.” Color said slowly. He noticed Killer looked upset.
. . . . .
“Hi.” Killer replied after a moment.
“Whats up? Wanna talk about it?” Color was always so good at being gentle with Killer but firm when he had to be.
“They think I’m horrible.” He said plainly like it was the most well known fact in the world.
“Who does?”
“Everybody. . . Dust and Horror don’t even wanna help me with something i fucked up on and Cross told me to beat it.” Killer continued to stare at nothing.
Color listened intensely, Killer had always had a rocky relationship with Nightmares other lackey’s. Well ex lackey’s now.
“And now my new friend thinks i just want her for sex and is traumatized and I’ve been triggering her by accident. . .” He trailed off thinking for a moment. Tears started to well in his eyes.
“No it wasn’t an accident, she told me to stop and i didn’t. Then she finally snapped at me. . . I deserved it. Now she’ll never wanna be friends with me again.” He put his hand sup covering his face so Color wouldn’t see him crying.
Color nodded slowly in thought. “Did you want to have sex with her?” He asked.
“. . . I wouldn’t be apposed to it.” Killer started slowly. “But thats not why i befriended her. Or why i was there today.”
“Why’d you befriend her then? Why were you there?”
“She seemed interesting. She hand a band t-shirt on and piercings on her nose and ears and she seemed like she’d be fun to talk to. I like the band that was on her shirt.” He stopped for a moment.
“Today i wanted to surprise her at work with tickets to a concert. . I thought she would like it. .” Another pause as Killer choked back a sob. “But she wasn’t there, so i went to her house and waited around for her. But i guess i messed up by not immediately telling her when she came down about the tickets.”
Color waited for Killer to finish the story before asking anything else.
“She was in a bad mood i could tell, so i was trying to joke around with her first to get her to relax. But that only made her more upset.” He sighed.
“She told me she had been through something awful and me flirting with her was triggering that. . .” It went quiet again for a while, Killer holding back sobs.
Color turned over onto his side and lifted an arm up. Killer silently looked over between his fingers, then moved over onto his side and cuddled up to Color. He started to really cry now. “I didn’t wanna hurt her.”
“I know. We’ll fix this, i promise.” Color said gently rubbing his back.
It was the next day. You had called in sick yesterday and today to give yourself some time to think and calm down. You ran yourself a nice relaxing bath and made yourself some tea.
You felt like maybe you had been too harsh to Killer. . . But he was the one who kept ignoring your boundaries.
You did regret hitting him though.
Sitting on the couch drinking your tea, in your coziest pajamas, you heard a knock on your door. Sighing you sat up, put your tea down and walked to your door. Slowly opening it you paused as you saw Killer.
“Hey-“
You went to shut the door but he grabbed it.
“Look. . Im sorry. Please can you hear me out?” He asked softly, one eyelight still in his eye socket.
You glared at him. “You have 5 minutes.”
“Im so sorry! I didn’t mean to make you think all i wanted was sex! Thats not why i befriended you at all!” Killer started nervously stumbling over his words quickly.
“I mean don’t get me wrong your beautiful, but i actually saw your band shirt and thought ‘oh hey cool someone Also likes this band’ and wanted to talk to you about it cause nobody else i know likes it.” Your eyes widened, and you stared at him in shock.
“So we started talking and i thought oh my god you’re cool, we like similar things we could be friends! And i always flirt with all my friends even strangers its never a sexual thing its just something i do i don’t know why.” Killer stopped to take a breath, tears started prickling his sockets.
“But i should’ve stopped when you asked, I have no excuse as to why i didn’t. I just wasn’t taking you seriously, and for that I’m sorry.” He paused looking up at you. You stared down at him, not knowing what to say, so he started talking again.
“And yesterday i wasn’t asking for sex at all i promise! I was at your work cause. . . I wanted to surprise you with tickets to your favourite band.” Killer pulled out the tickets from his pocket, two, one for each of you. It wasn’t even for a band he liked. When he handed them to you, you just held them gently in your hands, staring at them dumbfounded.
“When i saw you were unhappy i tried to joke around play flirt to get you to relax but that just made everything worse. I should’ve stopped when you said to. . Like i said there’s no excuse, i hurt you and i have to pay the consequences.”
You stared back up at him, shock written over your face. This was the most sincere apology you had ever gotten in your whole life, and he wasn’t even done yet!
“You can keep the tickets, go spend them with who ever you’d like, i understand if you don’t wanna be friends anymore i wont be offended. Thats all, goodbye.” Killer turned to walk away, but you stopped him.
“Wait!”
He turned around to look at you, hopefulness in his eyes.
“I know who i wanna use the tickets with.”
Oh of course, you were rubbing it in. It made sense he deserved it after all. “Well I’m glad you have someone in mind already hope you two have fun!”
“I. . . wanna go with you.” You say shyly.
Huh??? Killer was taken aback you- you wanna go with him? “Why? I was messing with you on purpose just to see your reactions. I wasn’t listening to you- why-“
“Yeah and you’re still a jerk for that, but. . . That was the most raw honest apology I’ve ever gotten. And nobody i mean nobody has ever done something like. . this!” You held up the tickets, “for me!”
It was Killers turn to stare wide eyed. “Really? nobody?”
“Nobody! So. We can. . I guess we can start over. . But no more flirting got it?”
“Got it!” Killer had a pep back in his step. “Though i cant promise i wont do it on accident. . I’ll try my hardest!”
“Alright. .”
The concert was amazing, Killer bought those light up sticks and you danced to the music waving them around your head wildly.
Killer had fun watching you dance and sing to the music, he even started dancing and singing along to!
You looked so cute when you danced, his face light up in blush, he wanted to kiss you. But he knew you weren’t ready for that, so he held it off, maybe another day another time.
Until that day. He’d enjoy the music.
