Blood splattered around the corpse. Lights flashing red and blue every second. Rain had just stopped pouring. It wasn’t surprising to see another murder, but it was for the police. It’s the third time this week. A third murder crime. It has the detectives spiral their heads over on why this is happening and who is the killer. Detective Kim Dahyun was one of the detectives to solve this crime. She sighed as she rubbed her head in frustration before looking at her co-worker, Squad 1 Captain Hirai Momo. “This is the third time this week..” She mumbled as she walked back over to her “If we don’t find and arrest this killer, we’ll lose more citizens than saving them.” Dahyun explained, Momo tsking out as she lit another cigarette “We even have Detective Sana on this.. Chief Jihyo on this.. Hell, we even have a gang involved just because we are this desperate to solve this crime.” Momo exclaimed, making Dahyun look back at the corpse “The only thing that’s bothering me is that this killer doesn’t leave any traces, any evidence, to even have just the slightest progress.” Dahyun rubbed her forehead. Momo sighed before patting Dahyun’s shoulder “We’ll solve it, somehow.” Momo said, trying to ease Dahyun’s burden. Dahyun showed a tired smile before nodding “Alright, call in the clean up crew and the forensics team, we need even the smallest evidence or lead to be finally able to catch the culprit.”

The door to a secluded convenience store opened, a girl that looks roughly around her 20’s entered. Wiping away the blood on her hands as she walked up to the cashier “Tulips are blossoming by the bay.” She mumbled, the cashier looked up before motioning for the back door “They’ve been waiting.” He tiredly said before going back to whatever he was doing prior. The girl nodded before opening the back door, heading towards a dimly lit hallway and another door at the end. Y/n took her hood off as she tsked out in frustration “Fucking hell.. It’s too hot these days..” You complained as you walked down the hallway, looking at your blood stained hands before shoving them inside your pockets. You opened the door, letting it creak, revealing a dimly lit room. At the center sat your sister, Lim Nayeon alongside one of her subordinates, Son Chaeyoung “I’m back.” You said tiredly as you plopped down at the couch, sighing, putting your head back onto the couch “Fucking hell..” You mumble as you hear Nayeon chuckle “Did you run into anyone?” She asked, you shook your head “What do you see me as? An Amateur?” You scoffed, looking at your sister with disbelief “Just checking, you can never be too sure, even if you can leave like a ninja.” Nayeon shrugged, you sighed as you scrolled through your phone “Where are the others?” You asked “Jeongyeon Unnie is with Mina Unnie, but I don’t know where they are” Chaeyoung replied, making you groan.

“I’m hungry.” You mumbled before calling Jeongyeon. You let the phone ring before you hear Jeongyeon’s voice “Y/n? Are you in trouble?” She immediately asks, concerning lurking in her voice “No no, I just want you to stop by to get some food please.” You ask as you chuckle, you hear Jeongyeon sigh, already imagining her eyes rolling at such a request “Fine, what do you want?” She asks, making you grin “Tteokbokki and Fish cakes.” You said smugly, hearing Jeongyeon chuckle “Alright, I’ll see you guys in a bit. Tell Nayeon I love her.” Jeongyeon teased before hanging up “LIM NAYEON GET YOUR ASS A ROOM WITH YOUR GIRLFRIEND AND LEAVE ME OUT OF IT.” You yelled as you fake a gag, making Chaeyoung and Nayeon laugh “Oh Y/n, one day you will know what it’s like to be in love.” Nayeon said to you, making you physically recoil “Love? The fuck? Hell no.” You said as you scoffed “If they can get past the walls I built.” You said as you shrugged, making Chaeyoung sigh “When will you finally let someone in, Unnie?” The younger girl asks as you glance away, letting your thoughts consume you ‘Yeah, when will I finally let someone in?’

Dahyun rested her head on the table, papers scattered across the mahogany as she tried to find leads, anything at this point, to even have the slightest clue on who was behind all the killings. Momo and the rest had already gone home, Dahyun was the only one left in the building “Bullshit.” She mumbled to herself as she leaned back onto the chair, looking at the documents, the forensic reports, everything that had a possible lead to the case. Not even one had a single lead “This murderer is smart, like they were trained to do this..” She mumbled as she looked at the pinboard that was scattered with numerous pictures of corpses, all in different locations, yet she noticed one pattern. They were all men, “What the..” Dahyun stood up as she looked at the pictures carefully this time, looked at every single one, and they all had one thing in common, ‘The murderer is targeting men?’ Dahyun thought to herself before noting it down inside her notebook “That’s one crazy man hater..” She laughed to herself as she plopped down on her chair once more, closing her eyes to take a quick rest.

Not long after, her phone buzzed. She glanced at the notifications that were piling up, various text messages from different people. Squad 1 Capt. Momo, Chief Jihyo, her parents. Everything was overwhelming her. Dahyun decided not to reply, putting her phone face down onto the mahogany before going back to work, ‘Not only are they men, but they are all killed at similar times.’ She thought as she looked through the deceased’s files

‘They were all nearing midnight or atleast midnight’ Dahyun thought to herself before noting the time stamps on some sticky paper then sticking it to the pinboard. She looked at the messy pinboard, various pictures, all different locations, and yet, no leads to whoever was behind the killings on Insa-Dong Street. Dahyun rubbed her temples before sitting down, deciding to call it a night before cleaning up the scattered papers, putting them all neatly inside a folder. Standing up, grabbing her bag and car keys, Detective Dahyun went up and left, calling it a day.

You were at the rooftop of the building, pondering something deeply that you didn’t notice Mina walking up behind you “You seem deep in thought.” She said softly, making you glance at her “You scare me.” You replied, making her chuckle “It’s my specialty.” She simply said before standing beside you “How did you let Chaeyoung in..” You asked softly, looking at the city lights “I mean, like.. How can someone like us ever receive love? Or atleast be accepted by someone?” You looked at Mina who was already looking at you “Because I know I can’t handle everything on my own.” Mina stated, making you look confused “I didn’t let Chaeyoung in just because I simply needed help, I let her in because in a way she makes me feel comfortable enough to let my walls down, to just be myself.” Mina continued, looking at the city lights in the distance “It’s not just because I simply needed help or that I know I like her. It’s deeper than that, Y/n” She continued “And you won’t understand the concept of letting someone in until you find someone who you, yourself, will experience love.” She said, looking at you “… But how did she learn to accept you that we are.. you know, this?” You asked, “That we are murderers?” Mina asked, you nodded “That was kinda hard, it’s unexplainable how.” She chuckled, you hummed “Yeah, considering the fact that we’re literally being paid to have a mass murder on men right now..” You sighed as you rubbed your head “I wouldn’t be surprised if someone found a lead, I killed three in a week.” You stated, making Mina chuckle “You’ll find someone, I know it.” Mina tried to comfort you, making you nod “I just hope they’ll.. you know, accept me? I guess?” You said softly, vulnerability visible in your eyes, making Mina sigh “Look, it wasn’t easy for Chaeyoung to accept what I did for a living.” Mina stated “But it took time, a hell lot of time. We had multiple fights because of it.” Mina continued “But eventually, she just accepted it and somehow also got curious.” Mina chuckled, “That’s why she’s under Nayeon right now.” Mina looked at you “You’ll find someone who will love and accept you one day.”

You looked at Mina before smiling “Thanks.” You softly stated, making Mina nod “Don’t worry, I had doubts like this aswell, it’s normal considering the fact that we also kill.” Mina shrugged as she chuckled, making you roll your eyes “Yeah yeah, whatever lovebird.” You teased, making Mina gasp “Hey, I just helped you with your doubts and now you’re teasing me?” She stated in a fake offended voice “Well because you are a love bird, to Chaeyoung at least.” You stated the fact, making Mina chuckle “God, I hate that you are Nayeon’s younger sister” She stated “That makes two teasers, and two skilled killers.” You said smugly before looking at the city lights “It’s pretty.” You said, making Mina nodded “Yeah, this was my favorite view back then when I had doubts falling for Chaeyoung.” Mina stated, making you sigh “I just hope I’m able to let someone in after all these years.” You stated, Mina hummed “You will, I know you will.”

A few days have passed, you, Chaeyoung and Mina decided to head to the city to buy some needed groceries. You let them handle whatever needed to be handled at the grocery shop, while also picking some goodies for your own. You were lining up to pay when you decided to head out first to get the car ready. While doing so, you ran into Dahyun, who seemed to be looking at you while someone was pestering her “Hey, uhm, I know this sounds crazy but can you act like my fake girlfriend? Just until he leaves.” Dahyun walked up to you, whispered while holding your hand but keeping a small distance “Yeah? Is he bothering you?” You asked as you glanced at the man that was approaching you both “Mmhm.” Dahyun hummed before looking back, the man nearing you and Dahyun “Come on, please? Just one date?” The man looked at Dahyun once more, you sighed before pulling Dahyun closer by the waist “Back off buddy, she’s mine.” You stated as you looked at the taller being

“You? She’s got horrible taste if she’s dating the likes of you.” The man said, making you scoff “Me? I’m better than a sorry excuse of a man like you.” You said cockily, holding Dahyun closer “And besides, I can do shit you can’t do. Like treat my girlfriend better than you cheating fucks.” You continued as you glared at him “Now, I want you to fuck off. She’s mine.” You looked at him one last time before tsking out, holding Dahyun’s hand “Let’s go baby.” You mumble as you lead her into the grocery store where Mina and Chaeyoung is, leaving the man frustrated. You walked down near the chips aisle before looking at Dahyun “Hey, you okay?” You asked, Dahyun smiled gently “Yeah, thank you by the way.” She said, making you nod “It’s fine, it was nothing.” You shrugged as you glanced over the cashier to see if Chaeyoung and Mina were still around “I think it’s safer if you head on home now, it’s better to stay indoors than to roam around at night.” You stated, making Dahyun nod “Yeah I will, I just so happened to bump into that guy, I was trying to find someone to help me.” Dahyun said, making you chuckle “Well lucky you, you just so happen to bump into me.” You teased, making Dahyun giggle “I’m Dahyun by the way, Kim Dahyun.” She introduced herself to you “I’m Y/n.” You simply stated before hearing Chaeyoung call out for you “Oh, I have to go now. It was nice meeting you” You said to Dahyun before waving “Yeah, you go on ahead, thank you again!” Dahyun said before you left

You left with Chaeyoung as you approached your car again once more, Mina was packing the groceries into the back of the car before Chaeyoung teased you “Sooo.. Who was that you were talking to just now?” Chaeyoung teased, making you groan “She was no one, Chae.” You stated as you got into the driver’s seat, Chaeyoung and Mina at the back seat “You sure about that?” Mina chimed in with the teasing, making you roll your eyes “Please, I doubt she’d fall for me, even if I did save her—“ You tried to explain but was cut off by Chaeyoung “You saved her?!” She exclaimed, making you regret she ever found you talking to Dahyun “Yes, from a creepy disgusting man. Now can we please drop the topic?” You asked as Mina chuckled from the back “We will, but we will interrogate you first.” She teased, making you groan “God, I’d rather do anything than be interrogated just for talking to a girl!” You exclaimed as the two laughed at the backseat.

Dahyun returned to the building as Momo and Jihyo were standing near the lobby “Hey, what took you so long?” Jihyo asked out of concern, Dahyun nodded “Yeah, aside from the fact a creepy guy tried to ask me out and a pretty girl saved me, otherwise I’m okay.” Dahyun explained, leaving Momo and Jihyo baffled, “What?!” Momo exclaimed, looking at Dahyun “What? I’m here, ain’t I?” Dahyun looked at the two who looked back at her with concern, “Oh please, I’m perfectly fine.” Dahyun huffed “Yeah, but elaborate on the part where you just said a creepy guy tried to ask you out and a pretty girl saved you?” Jihyo looked at Dahyun “Oh, yeah. On my way here, a guy tried hitting on me but I turned him down because I don’t like guys that way. So after that, he was so persistent about it, I tried leaving but he wouldn’t budge.” Dahyun explained “It just so happened Y/n was there and I told her to act like my girlfriend just to shoo the guy away.” Dahyun continued, Momo and Jihyo listening intently “So after that, the guy did leave after Y/n led me into the nearby grocery store and told me that I shouldn’t be wandering around the streets this late at night because of guys like him.” Dahyun finished explaining, looking at Jihyo who let out a deep breathe “Atleast someone was there to save you, but why didn’t you contact me or Momo? You know we would’ve picked you up from your apartment.” Jihyo explained, Dahyun let out a small chuckle “Well, I wanted to walk so that’s why I decided to walk today, I just didn’t expect a guy like him was wandering.” Dahyun explained, Momo hummed “Next time you do, just think about calling for us instead.” Momo said, making Dahyun nod “I’ll keep that in mind.”

You entered your shared flat as Mina and Chaeyoung put away the groceries, you tossed the car keys near the counter before plopping down onto the couch “I’m so tired..” You mumbled out before Nayeon entered the room “We have another suspect to kill.” Nayeon said outloud, you closed your eyes “Ruiz Duskbane, 24” Nayeon continued “So, who’s killing him?” You asked, Nayeon looked at you with a knowing look “You obviously.” She said, “I thought it was Jeongyeon’s turn?” You asked as you looked at your older sister “It’s still you that’s being requested, N/n.” Nayeon shrugged as you scoffed “Damnit.” You cursed before plopping back down onto the couch “Nayeon Unnie! Did you know N/n was talking to a girl?” Chaeyoung said to Nayeon as she teased you, your eyes widening “Nope! Nope, we are not doing this Chaeyoung!” You exclaimed but it was too late, Nayeon looked at Chaeyoung curiously “A girl, huh? Is that so N/n?” Nayeon started to tease you “No, it’s too late for this. I am going to bed.” You said before standing up to go to your room, hearing the three snicker after teasing you.

You shut the door of your bedroom before leaning against it, letting out a sigh as you closed your eyes ‘Fuck, she did look pretty’ you thought as you licked your dry lips, standing up and heading over to your bed as you sat down on the edge of it. You opened your phone to decide to scroll around, maybe stalk her profile—What?! No way you were going to do that, right? The screen illuminated your face as you started going through your socials, curiosity killing you, so you decided to type in her name on Instagram, her profile wouldn’t show up… right?

Her profile showed up, deciding that you’re already in this situation, you decided to click on it, there’s no harm in—“Holy shit she is hot.” You mumbled as you scrolled down her profile, there were pictures of her in her detective uniform, some in casual wear, and others were pictures of beautiful scenery. What caught your eye was that she was part of the Police ‘A detective, huh?’ You thought to yourself ‘I better be careful when I run into her next time.’ You hummed as you turned your phone off and stood up to get ready for bed. ‘But then again, it’s such a small chance to run into her with a city this big.’ You chuckled to yourself as you got into your pjs, sliding into the comfort of your bed as you prepared to go to sleep.

“There is no way I am going to some club just to kill. That is a risky job, and a risky place to even murder someone. Imagine seeing a dead body on your night out?!” You exclaimed, Nayeon sighed as she rubbed her forehead “Well that’s what you are assigned to! I can’t change that, plus, are you seriously going to turn down $25,000?” Nayeon asked, making you click your tongue “It’s too risky, Unnie.” You mumbled “I could easily get arrested. Not to mention, I barely leave traces of myself when I do kill. That’s why I’m still here and not behind some metal bars.” You said, making Nayeon sigh “I know that but the money, Y/n.” Nayeon was persistent with the job. Sure, you five needed the money, but at what cost? “Nayeon, hear me out, it’s too risky even if I have an alibi to cover for me. There’s just going to be too many people surrounding the club, and not to mention, security is higher nowadays because of us” You explained “It’s not simple but it’s not safe either.” You finished, making Nayeon think “Look, I know that, that is why Mina and Chaeyoung will be there to accompany you—“ Nayeon was cut off by you “You’re seriously thinking about the money over the well being of your own sister?!” You exclaimed, making Nayeon roll her eyes "Poison him then, you know murders aren’t all knives and guns.” Nayeon bluntly stated.

“Fine whatever, but don’t expect me to be back that quick. It’s a fucking club for god’s sakes.” You tsked out, Nayeon sighing “I love you, N/n but..” Nayeon trailed off, you understood her side anyway, regardless of bantering with her earlier “I know. I know. It’s just risky.” You explained, making Nayeon nod her head “So will you take it?” Nayeon asked, you nodded “Yeah, yeah, poisoning someone will be fine. It’s Ruiz Duskbane right?” You asked, Nayeon nodded before showing you a picture of the target “Alright, I’ll strike tonight. I’m bringing Mina and Chaeyoung so it doesn’t look that obvious.” You leaned against the kitchen counter “And at least, they can get to go have fun once in a while.” You chuckled as Nayeon rolled her eyes playfully. “You know them, they’re probably going to make out at some point in the mission.” Nayeon giggled, making you groan “Oh god, if I see them making out, I’m throwing up.” You fake a gag, making Nayeon laugh out loud.

Xylo, Euljiro Seoul

You walked into the club with Mina and Chaeyoung, the two girls running off somewhere. You wore a messy suit, loosened up tie and the first two buttons of your oversized polo was undone, you wore some baggy slacks and some sneakers to top it off. You walked around near the counter before spotting your target ‘There you are Ruiz.’ You thought to yourself before a familiar figure showed up beside you “I didn’t expect you to be into these kinds of places” Dahyun said softly as you turned to look at her “Same goes to you.” You chuckled, Dahyun sitting beside you ‘Fuck this isn’t going as planned’ You thought before subtly checking her out, she wore a mid-thigh dress and a leather jacket “So, who are you with?” You asked, trying to find Chaeyoung or Mina subtly “Oh, with some of my friends, they’re enjoying themselves on the dance floor” She chuckled as she ordered a drink. By God’s miracle, Chaeyoung walked up behind you and tried to ask how the mission was going “Chaeyoung! Hey, so I have something to ask.” You turned to face her, your eyes signaling that you can’t do the mission, not with Dahyun around “Yeah? What’s up?” Chaeyoung asked as she glanced over Dahyun, who was receiving her drink. You handed the poison over to Chaeyoung subtly as you looked at Chaeyoung “Give this to Mina, I can’t kill someone in front of a detective.” You whispered to her before ushering her away, leaving Chaeyoung to chuckle to herself and finding Mina.

You turned back to Dahyun, who was giggling at your interaction with Chaeyoung. “Hey, sorry about that, I just needed to tell her something.” You said while rubbing your nape awkwardly, Dahyun shook her head “No problem, it’s cute. You guys look like siblings.” Dahyun snickered, making you laugh “Is that so, huh?” You teased Dahyun who rolled her eyes as she drank “Yeah, I mean, are you actually siblings?” She asked, you shook your head “Nope, my older sister decided to stay home today.” You said as you ordered a drink for yourself “It’s just me, Chaeyoung and her girlfriend. Thought I’d accompany them to head out once in a while you know?” You chuckled, making Dahyun snicker “Yeah, it’s good to get out once in a while you know?” She hummed, you looked at her clearly this time as she glanced over to the dance floor. She had long wavy black hair and beautiful dark brown eyes making you stare longer than you should’ve had “Hey, eyes on me.” Dahyun snapped you out of your trance, making her giggle as you looked away flustered “Sorry, it’s just that you are so pretty. I can’t help but stare.” You shrugged, Dahyun raising her eyebrow “I didn’t expect you to be that honest.” Dahyun chuckled.

——

It’s been quite a night. You saw Mina sneakily putting the poison powder into Ruiz’s drink, before he drank it. Making him look like he fainted from too many “drinks”, or whatever the bartender said. No one bats an eye on him, making the three of you complete the mission easily. Except for the fact that Chaeyoung and Mina had a few too many drinks, enjoying themselves on the dance floor. You let them since you guys barely even go out to enjoy the night, while also enjoying yourself with a couple of drinks. Dahyun had accompanied you all night, making you laugh, and making you lower your guard just this once. No one has ever made you lower your guard, not even Nayeon, which surprised you even more “Hey, let’s go on to the dance floor.” Dahyun looked at you with hooded eyes, clearly tipsy. “Yeah I don’t think that’s a good idea.” You chuckled as Dahyun pouted “But that’s no fun..” She sulked, making you chuckle even more “Is that so?” You decided to tease her, making Dahyun roll her eyes “Yeah! We’re supposed to dance the night away, and maybe even enjoy ourselves..” Dahyun slurred as you pulled her closer, making sure she’s near you since there were a lot of drunk men around “Yeah?” You mumbled softly as Dahyun rested her head on your shoulder “Mmhm..” She hummed as she wrapped her arms around your neck, playing with the ends of your hair, looking at you with hooded eyes “You’re drunk.” You whispered to her as you chuckled at her flushed face “Me? Drunk? No.” Dahyun huffed as she tightened her hold around you “Yeah, I think that’s enough.” You said, paying for both your drinks at the bar before dragging her off to the corner of the club “Mmph..” Dahyun hummed as she leaned against you, her perfume filling your senses as the influence of the alcohol was starting to take its effect, it didn’t help that the lights and sounds were all making you overwhelmed.

Dahyun cupped your cheeks as she snapped you out of your trance “You know, it’s nice to let loose for once.” She mumbled, making you raise an eyebrow “Yeah? You don’t get to do that often do you?” You asked, making her nod into your neck, your breath hitching “Yeah..” Dahyun replied, making you sigh and rub your thumb against the material of her dress “And you know..” Dahyun continued, “You’re actually pretty hot..” She mumbled, looking up to you, making you look at her with a teasing smirk “And what are you going to do about it?” You teased, making her bite her bottom lip “This.” She replied before kissing you softly, making your eyes widen before kissing her back. She hummed into the kiss as she held you close, you held her waist, keeping your hands near the end of her jacket. When you both pulled away for air, she panted against your lips and chuckled “Fuck, you’re a good kisser.” She whispered, you rolled your eyes as you smirked, pinning her against the wall behind her, she wrapped her arms loosely around your neck as she looked at you cockily

“Good kisser?” You scoffed playfully “Mmhm, a good kisser..” She replied before kissing you again, making you groan against her lips. She pulled you closer as you started to trail your lips down her neck, making her lean back onto the wall to give you more access to her snowy white skin “You know, Dahyun..” You mumbled against her neck, sending vibrations to her body “You’re so fucking hot..” You chuckled before sucking on a sensitive spot, making her shudder and whimper softly “Y-Yeah?..” She breathlessly let out before pulling you impossibly closer. “Mmhm, you’re so gorgeous.. and I wonder why you’re still single.” You pull back, licking your lips as you see a small trail of hickeys lining down her neck, grinning to yourself as she panted, looking at you with hooded eyes “Y/n..” She breathed out “God, fucking kiss me..” She said before pulling you in by your collar, smashing your lips together as you continued to make out. “Dahyun..” You pulled away as Dahyun whined at the sudden loss of contact “You know you’re drunk right?” You mumbled as she huffed “So what? Drunk actions are sober actions you know.” She replied, making you chuckle before pulling her closer “I just don’t want you to regret anything.” You mumbled “Especially not with me.” Dahyun looked up to you in confusion but you waved it off “Come on, let’s find your companions.” You said before holding her tightly, keeping her close to you as you two navigated the sea of people.

You asked each person that was on the dancefloor if they had accompanied Dahyun prior to bumping into you. Until you finally met Momo and Jihyo, who were sitting by the booth “Hey, uhm, this might sound strange but did you guys accompany Dahyun prior to losing her because she bumped into me?” You asked, Jihyo looking up to her phone before glancing at Dahyun, who was resting her head on your shoulder “Yes, oh my god.” Jihyo gasped as she reached out for Dahyun. “Yeah, sorry, she bumped into me by the bar and spent her time there.” You chuckled as you helped Dahyun sit down beside Momo, who pulled her closer “No worries, at least she was with someone whom she’s familiar with.” Momo replied, making you nod “Yeah, I’ll get going now. It was nice meeting you both.” You turned to leave before Jihyo grabbed your shoulder “Hey, what’s your name?” She asked, you smiled “Y/n.” Was all you said before leaving.

——

You basically had to drag Mina and Chaeyoung out of the club and into your car. Luckily, you were sober enough to drive but your head still hurt from the amount of alcohol that you chugged down. You started the engine to your car before driving the three of you back home. On the drive back, you thought about how Dahyun was the one person who accidentally let your guard down so easily. No one has been able to do that, not even Nayeon who is your elder sister. ‘Is this what they meant when I’ll know when I’ll be able to experience it?’ You thought to yourself before pulling up to the driveway of your guys’ apartment building. Heading up towards the parking lot, you easily parked the car before helping Chaeyoung and Mina out. You then locked the car before holding one of the girls’ hands and started to head into the building. It was roughly around 3:37 AM in the morning, you three entered the elevator before you pressed the button to your floor, rubbing your eyes slightly as the doors closed. You glanced over to Chaeyoung who was leaning against Mina “I ran into Dahyun.” You said softly, making the two girls glance at you “Yeah?” Chaeyoung slurred out, you nodded “Had a few drinks, that’s why I handed the poison to you. I couldn’t do it with her nearby.” You mumbled as you leaned against the walls of the elevator “Why so? You could easily and subtly put the poison into the drink, you know?” Mina asked as she pulled Chaeyoung closer

You sighed as you rubbed your head “She’s a detective Mina. She’s also most likely or possibly one of the detectives of the case of our murder schemes you know?” You pointed out that fact, the two girls nodded. The doors finally opened before you helped the two walk over to your shared flat. Grabbing the keys in your pocket before opening the door to reveal a dimly lit apartment, only the kitchen light was on “Nayeonie? We’re back.” You called out as you yawned, closing the door behind you as the girls went ahead to their shared bedroom. You leaned against the door before unconsciously reaching out to your lips where Dahyun had kissed you ‘Fuck.. I just made out with a detective..’ You thought, you closed your eyes before chuckling to yourself ‘Shit, that’s hot.’

A few days have passed. The one who assigned ya’ll the murder paid his promise and everything was back to normal. Not until a notification buzzed from your phone, you checked to see who it was, then your eyes widened. It was Dahyun, who sent you a text message, who asked if you were available to hang out this afternoon “Ohh, looks like someone’s got a date~” Jeongyeon teased from behind making you flustered “Jeongyeonie!” You hid your face as you groaned “It is not a date.” You replied, Jeongyeon rolling her eyes “Keep telling yourself that and you’ll eventually start to fall.” She continued to tease, making you bury your face into your hoodie “Nayeonie, control your girlfriend please.” You pleased for your elder sister, who chuckled at your flustered state “Jeongyeon, I think that’s enough teasing, she’ll blow up if you tease her any more.” Nayeon chuckled as you leaned back against the chair, looking at the message notification that was sitting peacefully on your phone’s roster. “Nayeonie, I’m heading out.” You said, Nayeon looking at you with a teasing smirk “Out for your date?” She asked as you wore a hoodie “Yeah yeah whatever, keep your delusions.” You groaned, grabbing your keys before heading out.

You parked the car onto the nearby parking lot before heading into the café. You opened the door and the smell of caffeine instantly hit you, you wandered around for a bit before noticing Dahyun sitting by the booth, she waved at you and you smiled gently. You walked over to the booth before sitting beside her “Hey.” She greeted you ss you chuckled “Hi.” You replied “So.. We skipped a lot of steps, huh?” Dahyun chuckled, you looked at her confused “What do you mean?” You asked, Dahyun looked away shyly. “What I mean is that, we literally made out a few nights ago and I barely even know you.” She looked at you, you hummed “I mean, you did say I was a pretty good kisser.” You teased her, making Dahyun roll her eyes “But I’m serious Y/n.” She said, you sighed as you looked at her “Alright, I guess we did skip some steps.” You mumbled before holding her hand “But it’s never too late to know you now.” Yoh smiled, making her flustered “I guess you do have a point.” Dahyun replied before leaning her head against your shoulder

The day was filled with teasing banter, very bad flirting attempts and it led to you and Dahyun walking by the park “So.. I know it’s been like, a few hours since we officially knew each other..” Dahyun whispered as she held your hand “But you feel so much like home.” She continued, you chuckled before looking at a nearby lake “Hm, that’s cute.” You hummed, before you felt Dahyun playfully punch you “Ow?” You yelped as you look at her giggle “Have you ever let someone in?” Dahyun asked, you looked at her confused “Letting in?.. How?” You asked, Dahyun hummed “Letting in, as in have you dated anyone?” She asks, you sigh as you shake your head “I never let anyone in.” You mumbled as you looked away, Dahyun, noticing your gaze wander “So why did you let me?” Dahyun asked, you looked at her slightly baffled, how did she even notice that? “I.. We aren’t.. What..” You stuttered, making Dahyun chuckle “I know dummy.” She hummed before walking ahead of you, leaving you baffled “Hey! Don’t leave me.” You caught up to her, making her giggle and hold your hand once more “Y/n?” Dahyun looked at you, you hum in response “Hypothetically, would you kill someone for me?” Dahyun asked, you looked at her, ‘Does she know?’ You thought before humming “Why would you ask that?” You reply, she shrugged “Just answer.” She said, you pondered for a while before nodding “Yeah, even if it meant going to jail.” You said, too quickly, Dahyun laughed before kissing your cheek “Cute.” She whispered, making you roll your eyes “What do you think of the ring I bought for you?” You asked Dahyun, Dahyun playing with a silver ring, had small diamonds embedded into the sides “It’s beautiful.” Dahyun replied “Thank you again, I thought about buying it for quite a while now.” Dahyun said as she leaned closer to you “No problem, cutie.”

Insan-dong Street, Seoul

Your breath was fogging out of your mouth as you panted, looking at the dead body in front of you. This was not a new sight at all, blood splattered against the floor, rain pouring heavily against you ‘Fuck, it’s cold’ You thought as you tsked out, wiping the blood off your shirt as you cleaned your dagger ‘I have to leave.’ You thought before cleaning up your hands in the pouring rain. Unfortunately, luck wasn’t by your side today. Red and blue lights start flashing, closing in the distance, your eyes widened as you heard the sirens approaching. You tried to run, you really did, but someone had already held your hands behind your back “We caught her!” Said a voice behind you, Chief Jihyo holding you tightly as you squirmed against her restrain “Fuck, let go!” You yelped as you tried to pry your hands away. Detective Momo and Detective Dahyun got out of the police car, Dahyun’s eyes widening at the sight of you “Y/n?” She could only ever mutter as Momo put cuffs on you “So you’re the jerk that’s been behind the murders.” Momo harshly said as the cuffs lock against your wrists, you look away, anywhere but Dahyun.

“Dahyun! We finally caught her! The murderer behind Insan-Dong street!” Momo said victoriously, you could only ever look away. Anywhere, anywhere but those dark brown eyes you grew to love. You never confessed, never told your feelings, in fear of being rejected “Y/n..” Dahyun mumbled as she walked over to you, her hands shaking slightly, Momo noticed “You know her?” Momo asked Dahyun, Dahyun looked at Momo, then back to you, then back to Momo “… Yeah.” She said, almost.. disappointed? “Oh.” Was Momo all ever let out “Dubu I..” You tried but her eyes, are those tears forming?.. “You.. Fuck.” Dahyun looked away as Momo dragged you to the car, pushing you down onto the backseat. All you could ever do was comply, because what can you do? You were weak for Dahyun. Your hands shook as the police drove you away, you don’t know what to think. What would Nayeon think if she found out her little sister got caught? What would Mina react knowing that the person she’s closest with aside from Chaeyoung is behind bars?.. What does Dahyun think now that she knows I’m a murderer?

Dahyun couldn’t say anything on the ride back to the department, Jihyo checking up on her every few minutes as they parked “Okay, no. You haven’t been this silent. It’s been 20 minutes, Dahyun. Spit it out.” Jihyo said as she looked at the backseat, Dahyun looked down, playing with the silver piece of jewelry in her middle finger “.. Y/n, is someone I met a few months ago. She’s the girl that saved me from that persistent man who wanted a date with me. She’s the one who took me back to you and Momo when I got wasted. She took me out on dates, and.. bought me the ring I always wanted.” Dahyun mumbled out “I didn’t expect her to be the one behind the killings.” Dahyun continued as she looked up at Jihyo “I like her too..” Dahyun confessed softly, Jihyo sighing, Momo looking away “We just.. can’t always expect good people.” Momo mumbled “Yeah but..” Dahyun tried to find an explanation but couldn’t.

——

You were sent into an interrogation room, hands bound by the silver cuffs as you sat down onto the black wooden chair, eyes looking tired as you gazed upon Chief Jihyo, who sat on the opposite side of the table. Dahyun and Momo behind the glass of the interrogation room “State your name.” Jihyo firstly started, you closed your eyes “… Lim Y/n.” You mumbled as Jihyo wrote it down “Why did you do it?” Jihyo asked, you looked at her tiredly and with a cold gaze “I ain’t telling you.” You said, Jihyo tsking out “Why did you kill men on Insan-Dong.” Jihyo asked once more, you rolled your eyes before looking away “Why not.” You answered, Jihyo scoffed “Don’t make me bring out Dahyun” Jihyo threatened, you straightened up. Dahyun behind the glass sighing softly “Did she really have to use that?” Dahyun mumbled softly, Momo chuckling “I mean, whatever makes the murderer confess..” Momo replied, Dahyun hummed “Fine fine, whatever.” You tsked out “Because I needed the money.” You replied “It’s not easy having to live off on deals.” You looked away, Jihyo noting it down “I see..” Jihyo hummed before looking at you “And who makes these deals?” Jihyo asked, you sighed “Usually other men who have grudges. There’s no pattern even if you analyze it.” You mumbled, Jihyo noting it down as she nodded, listening to you speak “That’s all, take her away.” Jihyo ordered the guard before Dahyun opened the door.

“Wait, I want to talk to her.” Dahyun said as she looked at you, you looked away, Jihyo sighed before moving to the back of the room “Fine, but I am staying.” Jihyo said with finality laced in her voice. Dahyun sat across from you, you looked away in shame “… Look at me.” Dahyun ordered, reluctantly making you look at those eyes, the eyes that make you weak to your knees, the eyes that will forever hurt your heart “… Why.” Was all Dahyun asked, you close your eyes before speaking “It’s the way I live. I live off deal to deal.” You said as you looked at her “It may not be.. the ideal job, but it keeps me alive, keeps me fed—“ You got cut off by Dahyun “Even if your hands will forever be stained in the blood of the innocent?” She asks, you go silent. They were really innocent.. well, mostly “You don’t know that.” You retaliated “Because the deals weren’t simply just grudges, Dahyun.” You said, Dahyun scoffed “And you expect me to be okay with that?” Dahyun said, you look down “.. No.” was all you muttered out as you look back up to her once more “… Get out of my sight.” Dahyun ordered the guards as she tells you to leave, you knew it was for the better, the guards tightly held each one of your arms as they escorted you out. Dahyun leaned back against the chair as Jihyo sighed “I’ll look into the victims’ records, maybe it’s true the deals are more than just simple grudges.” Jihyo said, Dahyun nodded “Okay..”

——

The guards pushed you into the cell before locking it, completely leaving you alone in the cold. You tsked out before rubbing your wrists where the cuffs had been. This couldn’t get any better, first you got caught, second you can’t even tell Nayeon or anyone, and third Dahyun found out. How can life get any better than this?! You groaned into your hands as you leaned against the wall, shuddering slightly at the cold feeling of the concrete walls. You look down onto your hands, still had a bit of dried blood from the victim you had killed. Until then, only silence could be heard, and the ongoing storm inside your head, and maybe the way you’re crying in silence because the one who stole your heart found out that you are a murderer of 5 men. You then heard the sound of heels clicking against the floor, you look up tiredly

“Look, if it’s another interview, you already got your answers—“

“Shut up if you want to get out of here.”

Dahyun? “Dubu? What are you doing here?” You asked as you stood up, facing her, Dahyun ran a hand through her messy hair “Breaking you out of here.” She mumbled before unlocking the cell, you stood inside of the cold facility looking at her like she was crazy “You do know you’re going to get in trouble?” You said, she nodded “And you do know you’re risking your career for this?” You continued, Dahyun still nodding “Yes, now follow me.” Dahyun instructed, holding your wrist as she led you through tight hallways and secluded dark areas “Dahyun.” You stopped by a near closed off area due to the renovation

“What now.” You heard Dahyun, you rolled your eyes before grabbing her waist “Dahyun, I like you.” You confessed, Dahyun looking at you wide eyed before looking away flustered “You murdered someone tonight and you’re confessing to me?!” She yelped softly, you chuckled “Better late than never.” You shrugged, Dahyun groaning before sighing into your shoulder “.. I like you too.” She confessed softly “Good.” You mumbled before kissing her gently, Dahyun hummed into the kiss as she pulled you closer “I hate you..” She muttered as she pulled away slightly from the kiss “You love me.” You teased, making Dahyun roll her eyes before dragging you “Come on, let’s get out of here.” She said before leading you to the back of the building “.. Try not to get caught again.” Dahyun said as she looked at you before glancing at your hands, sighing “… I know I can’t stop you because it is your source for surviving.” She said softly “But that doesn’t mean I won’t stop trying to catch you.” She winked at you, making you scoff “Fucking hell, Dahyun..” You chuckled, making Dahyun giggle before placing a spare key in your hand “Meet me at my apartment later, I have to put on an acting act back there.” Dahyun said before giving you a chaste kiss “See you later.. murderer.” Dahyun whispered into the kiss before sending you off.

Dahyun rushed inside the building as you hear the chaos slowly rising, you stood there, with the spare key, to Dahyun’s apartment, chuckling softly before running away into the night, not stopping, not even one second. Because if you did, Dahyun would catch you again, and that simple thought thrilled you more than you cared to admit.

“Where is she?! How did she escape?!”

“How the fuck do you lose sight of a young murderer?!”

Panic rises throughout the building as the police department realizes that a murderer had just escaped within their grasp. “Dahyun, check the cameras!” Momo ordered as she went down to get Jihyo, Dahyun rushing over to the cameras, checking her surroundings before deleting some footage from some areas she knew there was a camera. Dahyun then realized that she just gave the spare key of her apartment to a loose criminal, scoffing softly at herself as she felt the empty space in her pocket, ”God, that girl better be grateful..” Dahyun groaned softly but despite all that, Dahyun smiled just a teensy bit, knowing that her criminal girlfriend is on the loose, and probably waiting for her back at her apartment.

——

You unlocked the door to Dahyun’s apartment, quietly going inside before shutting the door behind your back and locking it once more. You made sure no one followed you, even if you were tired and exhausted. You reached out for your phone, texting Nayeon that you’ll be staying over at Dahyun’s apartment for the night before taking your shoes off and heading into the living room. You plopped down onto the couch as you finally rested properly after running for miles and miles from the department. Who knew Dahyun had the courage to bail you out despite knowing that you kill for a living. You chuckled at the sigh of Dahyun unlocking your cell before dragging you into hallways you never knew existed in police departments.

It was around 2:34 AM, You rested on the couch before you heard the door unlocking, you had your guard up slightly before seeing Dahyun’s messy hair, you heard the door close, before seeing Dahyun’s figure “Hey.” You greeted, Dahyun looked at you before you heard a sigh of relief “Thank God..” Dahyun mumbled out before walking over to you “You are an idiot, you know that?” Dahyun said softly as she sat beside you “Mmhm.” You hummed, Dahyun leaning her head against your shoulder “And a lot of explaining to do.” Dahyun continued, you chuckled “I’ll explain it, don’t worry.. For now..” You looked at her as you teased “Did you know that you looked hot bailing me out?” You said softly, Dahyun groaning “Please don’t..” You laughed softly, “Oh, but you were and I can’t help but think.. that I should reward you?.” You looked at her teasingly, Dahyun rolling her eyes before smiling “Whatever, Y/n.” She said softly before kissing you, crawling onto your lap, you sigh as you lean back onto the couch “Fuck Dahyun..” You mumbled out as you felt Dahyun slightly grinding herself onto you against your thigh “Be grateful that I love you.” She mumbled as she pulled away, looking into your eyes “Promise you won’t leave..” She said, vulnerability laced in her voice, you look up to her “I promise, swear on my life..” You replied before giving her a chaste kiss “And promise me.. You’ll stay, no matter what.” Dahyun continued, you nodded “I promise.” You gave her another kiss before hearing Dahyun giggle “Is that your way of sealing a promise?” Dahyun laughed into your lips “Mmhm, damn right.” You said softly before kissing her again.

You’re a secret worth ruining a career for. - Dahyun
