âHey there little girl.â A tall man walked up to you slowly. His eyes had a glint in them you couldnât quite place.
âUm hi. . .?â You asked carefully. Holding your hands to your chest, where was mother? And who was this stranger?
âWhat are you doing all alone. . .?â Bending down beside you to be at your level. His hand on one of his knees.
âIm waiting for my mommy. . .â You said truthfully. She had told you not to talk to strangers, but surely this question wouldnât hurt to answer right. . ?
He tilts his head a bit. âOh. .? And how old are you?â He asks, theres something about his smile, itâs crooked and off putting.
âIm. . nine. . .â Nervously you back up a bit, you really wanted this stranger to leave you alone you got a bad vibe from him. .
âWell arenât you such a pretty little girl~â He suddenly grabs your chin caressing it gently.
âWh. . What?â You pull away from him, confused and creeped out.
âSay sexy~ do you wanna come wait for your mommy with me~? We could have some. . . Hehe. . Fun~â he said with a hunger in his eyes. As he mentally undressed you.
âI. . I donât know. . She said not to talk to strangers. . .â You backed away from him slowly. Eager to get away to the warm and safe arms of your loving mother.
âOh come on! Iâm not a stranger! You can call me daddy~ and we could have some fun!â He grabbed your waist and held it tightly.
âStop! Stop! Let go of me!â You fought to get out of his grip. Something told you this wouldnât be fun.
âNow, now, pet, donât be like that~â he grabbed your wrist, stood up and started dragging you away.
âHelp!! Help! Someone help me!!â 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 heâd been. . . Flirty.
You hated flirtatious people, it always made you so uncomfortable and reminded you of. .
Of. . .
âHey sexy~â He had called you. . So many times. .
âShow of girl~â That cab driver said to you when you tried to go clubbing once.
âWiiwo~â A guy whistle to you on the street when you were 14.
âHey pretty girl~â Your first Boyfriend mimicked the sounds he made. .
âHey princess wanna have some fun tonight~?â You were drunk and they tried to drag you to there car. . .
âHi my names Killer but you can call me yours~ wanna head to my place and have some fun~?â 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 couldnât be a doormat forever.
Killer smirked when he saw your pissy face walk over to him. This asshole!
âNow what do i owe the pleasure?â He mocked politeness. Even faux bowing for you.
You put your hands on your hips. âStop flirting with meâ 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 heâd see!
âI- i- . . . Um. .â 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.
âI. . .â Shaking a little. âWhy are you in my house. . .?â
âOh is that all! Here i thought you were mad at me! Hahaha!â He just laughed and laughed at you, slapping his leg as he sat up. The nerve of this guy. .
âLook princess~â you shivered at the nickname, he seemed to perk up at this. âPrincess, princess, princess~â he purred reviling in the way your eyes closed shut and your hands trembled. Killer didnât know why this got to you so much, but man was it funny seeing you squirm.
âI simply wanted to see my precious beloved bestie at work today! But atlas you werenât there!â He said over dramatically, like it was your fault for not showing up for him.
Only one thought came to your mind. âAre you stalking me?â 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 didnât 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.
âOh heavens no! Haha, why would you think that? I was just- wanting to see you during your lunch break!â
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.
âAnyways doll~ since youâre not at work why donât you come over here and we can have some. Fun~?â He sing songed holding something up, but you couldnât 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 donât wanna. You donât 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.
âWhats wrong Sweetheart?â He put a hand on your shoulder. Looking at you like you were the one going crazy. Ha!
âGet off me. I donât wanna see you right now.â You slap his hand away, opening the door.
âHey now! Im just a friendly guy! Come on sexy Iâm just checking in.â
There was a newspaper on the porch of your house, picking it up you stared as you registered his worlds. âStop.â Came out of your mouth, like a thousand times before.
âAw come on dolly Iâm just tryna see if youâre okay! You didnât show up to work, you slept in and now youâre all angry for some reason! Just wanna know whats up pretty girl!â
You started breathing heavily. If he didnât stop. If he didnât. You told him to stop. Why wasnât he stopping.
You clutched the newspaper as hard as you could.
âStop. .â 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.
âCome on princess you know you wanna tell me whats wrong~ we can have some fun today just relax you and me-â
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. âWhat. . . Was that?â He asked slowly still in shock. . But he almost sounded angry? âWhat. Was that!?â He demeaned to know when you didnât answer.
âI. . .i . . You didnt stop when i asked you to!â You snapped back.
âExcuse me!? I was checking in on you-â killer dropped his hand from his face making a fist.
âNot the fucking checking in.â You pinch the bridge of your nose anger rising. âThe flirting!! Ive asked you to stop several times Killer and you NEVER DO!â You raised your arm in the air for emphasis.
Killer stopped and stared at you. âYou never told me why! I thought we were just being playful- you were being hard to get-â he started to make excuses. The god damn excuses every damn fuck boy makes.
âPLAYING HARD TO GET!? ARE YOU FUCKING KIDDING ME RIGHT NOW!?â You were seething, you could only see red. The red of his stupid fucked up soul changing to a glitchy target. âIM NOT PLAYING HARD TO GET!â
âTHEN WHAT ARE YOU DOING!? I CANT UNDERSTAND WHY YOUR NOT HAVING FUN IF YOU DONâT TELL ME!!â
Fun. Fun. Fun. Itâs always about fun. âWELL I DONâT WANNA HAVE FUN WITH YOU!! I DONâT WANNA HAVE FUN WITH ANYONE!!!â You clutch at your sides bringing your head down to make yourself smaller.
Killer looked confused. You didnât 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?
âYou. . . You donât wanna have fun with me. . ?â Killer was reeling. Had all of this friendship been a lie. . ?
âNO KILLER I DONâT WANNA HAVE SEX WITH YOU!!â You screamed out, not caring the door was open or that the neighbours could potentially hear you.
âWha- huh???â Killer blushed heavily. âIm not asking you for sex???â He was baffled. âWhy would you-â
âWhy!? WHY!? Youâre seriously asking me why!? god your so demanding Killer!!â You puffed your arms out to your sides going straight behind you. âFine. Fine! FINE!!! You really wanna know why!?â
Killer nods.
âCause i was sexually assaulted when i was a child thats why!â 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 didnât. . . He didnât mean to make you feel like he was trying to force you to have sex.
âI- i didnt-â Killer tried to step closer to you.
âGet out.â You stepped back.
âIm im sorry-â he stopped moving.
âGET OUT-â
âI-â
âGET OUT OF MY HOUSE!!â 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 didnât wanna have this fight with Killer.
Killer stood in front of the door just staring agape. He wasnât 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.
âDusstttt i fuckkkedd everythinggg upppâ Killer whinned like he was about to start crying, Dust knew he wouldnât tho.
âDoes it involve me. . ?â He asked seriously. If Killer had fucked up their residency he was going to kill him.
â. . . Noo?â Killer sounded unsure.
âThen suffer in silence.â Dust spat out unamused. Killer could deal with his own problems for all he cared.
âDussst! Come onnn!â Killer whined again. âHorror tell Dust to help me-â
âGo help yourself.â Horror snapped. âLeave Dust alone. If it doesnât involve us then weâre not gonna help you.â
âJeez you guys are in a bad mood what did i ever do to you?â Killer put his hands on his hips.
âYou want the long answer or the short answer?â Dust said plainly, lying back down onto the couch.
âGasp! I never. I cannot believe my too besties wouldnât help me out. Fine then Iâll take my business else where!â Killer walked out the door and slammed it shut.
âOh good heavens heâs gone.â Horror said as he got back to lunch.
Killer shortcuts to Crossâs place next.
Cross was hanging out with some friends when Killer started shouting for his attention. âCrossy! Hey! Hey crossy!â Killer was hopping on one foot waving his hands in the air.
When Cross notices Killer he cant help but sigh. âOh dear god. Hang on a second Alphys, i gotta go deal with the trash.â
âGood luck.â Alphys said back to him as she watched him walk towards Killer.
âSigh what do you want Killer?â Cross said as he got closer to Killz.
âHi Crossy! I um. Need your help? i kinda fucked up-â Killer started.
âNot helping you, go deal with your own shit yourself.â Cross quickly turned heal and started walking away.
âWha- hey!! Whats with everyone hating on me today!?â
âDo you really wanna know why?â Cross asked.
âYeah!â Killer said.
âItâs cause youâre an annoying piece of shit. Leave me alone Killz.â 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.
âHey.â Color said slowly. He noticed Killer looked upset.
. . . . .
âHi.â Killer replied after a moment.
âWhats up? Wanna talk about it?â Color was always so good at being gentle with Killer but firm when he had to be.
âThey think Iâm horrible.â He said plainly like it was the most well known fact in the world.
âWho does?â
âEverybody. . . Dust and Horror donât even wanna help me with something i fucked up on and Cross told me to beat it.â Killer continued to stare at nothing.
Color listened intensely, Killer had always had a rocky relationship with Nightmares other lackeyâs. Well ex lackeyâs now.
âAnd now my new friend thinks i just want her for sex and is traumatized and Iâve been triggering her by accident. . .â He trailed off thinking for a moment. Tears started to well in his eyes.
âNo it wasnât an accident, she told me to stop and i didnât. Then she finally snapped at me. . . I deserved it. Now sheâll never wanna be friends with me again.â He put his hand sup covering his face so Color wouldnât see him crying.
Color nodded slowly in thought. âDid you want to have sex with her?â He asked.
â. . . I wouldnât be apposed to it.â Killer started slowly. âBut thats not why i befriended her. Or why i was there today.â
âWhyâd you befriend her then? Why were you there?â
âShe seemed interesting. She hand a band t-shirt on and piercings on her nose and ears and she seemed like sheâd be fun to talk to. I like the band that was on her shirt.â He stopped for a moment.
âToday i wanted to surprise her at work with tickets to a concert. . I thought she would like it. .â Another pause as Killer choked back a sob. âBut she wasnât 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.â
Color waited for Killer to finish the story before asking anything else.
âShe 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.â He sighed.
âShe told me she had been through something awful and me flirting with her was triggering that. . .â 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. âI didnât wanna hurt her.â
âI know. Weâll fix this, i promise.â 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.
âHey-â
You went to shut the door but he grabbed it.
âLook. . Im sorry. Please can you hear me out?â He asked softly, one eyelight still in his eye socket.
You glared at him. âYou have 5 minutes.â
âIm so sorry! I didnât mean to make you think all i wanted was sex! Thats not why i befriended you at all!â Killer started nervously stumbling over his words quickly.
âI mean donât get me wrong your beautiful, but i actually saw your band shirt and thought âoh hey cool someone Also likes this bandâ and wanted to talk to you about it cause nobody else i know likes it.â Your eyes widened, and you stared at him in shock.
âSo we started talking and i thought oh my god youâre 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 donât know why.â Killer stopped to take a breath, tears started prickling his sockets.
âBut i shouldâve stopped when you asked, I have no excuse as to why i didnât. I just wasnât taking you seriously, and for that Iâm sorry.â He paused looking up at you. You stared down at him, not knowing what to say, so he started talking again.
âAnd yesterday i wasnât asking for sex at all i promise! I was at your work cause. . . I wanted to surprise you with tickets to your favourite band.â Killer pulled out the tickets from his pocket, two, one for each of you. It wasnât even for a band he liked. When he handed them to you, you just held them gently in your hands, staring at them dumbfounded.
âWhen i saw you were unhappy i tried to joke around play flirt to get you to relax but that just made everything worse. I shouldâve stopped when you said to. . Like i said thereâs no excuse, i hurt you and i have to pay the consequences.â
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 wasnât even done yet!
âYou can keep the tickets, go spend them with who ever youâd like, i understand if you donât wanna be friends anymore i wont be offended. Thats all, goodbye.â Killer turned to walk away, but you stopped him.
âWait!â
He turned around to look at you, hopefulness in his eyes.
âI know who i wanna use the tickets with.â
Oh of course, you were rubbing it in. It made sense he deserved it after all. âWell Iâm glad you have someone in mind already hope you two have fun!â
âI. . . wanna go with you.â You say shyly.
Huh??? Killer was taken aback you- you wanna go with him? âWhy? I was messing with you on purpose just to see your reactions. I wasnât listening to you- why-â
âYeah and youâre still a jerk for that, but. . . That was the most raw honest apology Iâve ever gotten. And nobody i mean nobody has ever done something like. . this!â You held up the tickets, âfor me!â
It was Killers turn to stare wide eyed. âReally? nobody?â
âNobody! So. We can. . I guess we can start over. . But no more flirting got it?â
âGot it!â Killer had a pep back in his step. âThough i cant promise i wont do it on accident. . Iâll try my hardest!â
âAlright. .â
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 werenât ready for that, so he held it off, maybe another day another time.
Until that day. Heâd enjoy the music.
