part 1 || part 2 || part 3
“can we talk?”
you stop in your tracks, one of your arms caught by the blonde twin. you unknowingly tug back the twin who held onto your other arm. osamu turns around and makes eye contact with the two of you, face dropping slightly from the small smile it previously had.
the three of you stay in that awkward position for a second, while you debate whether to give atsumu the time of day. even though he had royally pissed you off, the whole point of the plan was to catch his attention. but at the same time, mei was still standing behind him, helpless puppy facade quickly fading by the second. but did you want to let go of the months you had with atsumu so quickly? people do make mistakes-
“you should stay here.” osamu’s steady voice interrupts your train of thought. you give him a look of surprise, half expecting him to call his brother a scrub and drag you away.
“are you sure?” you question dubiously. osamu gives you a small nod and reassuring smile, filling you with a rush of something you weren’t expecting. why was it getting warmer in the house? and why was your stomach erupting into somersaults?
as quickly as you felt it, it disappeared as osamu let go of your arm and took a step back. you felt a pang of disappointment, but couldn’t focus on it as atsumu tugged you back towards him. your eyes left osamu and turned to your talking stage of much too long.
atsumu led you away from the busy area, upstairs towards one of ginjima’s guest rooms. you don’t miss how mei’s eyes follow the two of you, heartbreak and anger written on her pretty features. oddly enough, you don’t feel any satisfaction from it, only an irrational irritation at atsumu’s ability to break hearts. you tear your eyes away from her and towards the handsome blonde as he pulls you inside a room and closes the door behind you two.
you stand awkwardly as atsumu’s eyes scan your face, unsure of what he’s looking for. you stay silent for what seems like forever, before atsumu decides to speak up.
“i’m sorry.” he professes, a surprising amount of sincerity in his tone. you’re taken aback, eyes widening in shock. that was the last thing you had been expecting.
“what?” you ask dumbly. he sighs, before repeating the two words that shocked you to your core.
“i’m sorry. i was being an ass earlier. i shouldn’t have left ya for mei, and i shouldn’t have snapped at ya for pressing me.” atsumu proclaims, seeming truly genuine as he grabs your hands and stares into your eyes. you resist the urge to avert them at his deep gaze.
“oh.” you finally respond, at a loss for words at his apology. it’s unlike you to not have something to say, but in this scenario you were rattled to your core. too much had happened tonight and you were far past your full mental capacity. and a sincere apology from atsumu? well that was practically unheard of.
he didn’t seem to take your response (or lack thereof) to heart and continued on.
“if i’m being honest, the whole mei thing started as a ploy to make ya jealous.” he confesses, shocking you all over again. he wanted to make you jealous? “when she called me and asked me if i wanted to do the costume with her, i was going to say no and tell her that i already had one planned. but then she started sobbing about how her boyfriend dumped her and she needed someone and i felt bad.”
your shock was slowly morphing into anger at his dumbass explanation. you could tell exactly where this was going.
“and then, i thought about how hot you would look all possessive and territorial over me,” he continued, sheepishly confessing to something that made your blood boil. “i was acting like a dumb teenage boy.”
“you have the stupidest instincts of anyone i know,” you manage to get out, unsure of what to say to that confession. atsumu groans and smacks his forehead with his palm.
“i know, i know,” he admits, seeming genuinely distressed. he lets his hand fall and steps closer to you, sliding his arms around your waist. your pulse begins to pick up. he brings his mouth down to your ear, making you shiver as he brushes his lips against your cheek.
“i couldn’t stand watching my brother touch you like that,” atsumu murmured, tracing a light hand over the side of your face as your breath catches in your throat.
“you said we weren’t exclusive,” you try to snap back pettily, but it comes out barely a whisper.
“i was stupid,” he muttered, almost possessively tightening his grip on the side of your face. “i want ya all to myself.”
your eyes flutter shut as he comes down and molds his lips against yours, kissing you deeply. you squeak in surprise, even though this is something you’ve done with him many times before. he pulls you into him like it’s a routine, and your arms find themselves looped around his neck.
but something isn’t right.
your mind begins to wander as you make out with atsumu. you imagine your hands buried in grey hair instead of blonde. you think back to just 10 minutes ago, when osamu’s lips hovered millimeters from yours. you think about the rush of disappointment that hit when he used his teeth to pick the lime wedge, and didn’t even so much as brush his lips against yours.
you can’t help but wonder what his kiss would feel like. would it be brash and intense like atsumu? or would it be slower, deeper? would he take his time with you, kiss down your neck and dangerously close to your chest? would it be anything like the sensation of him sucking the tequila off of you, licking the salt off your soft skin?
you’re filled with too many thoughts of atsumu’s brother, and eventually it’s too much to take. you find your strength and grab atsumu’s biceps, gently pushing him away from you.
atsumu looks caught off guard, shooting you a look of confusion.
“why did it take osamu doing a body shot off me for you to realize that we should be exclusive?” you eventually find your words, hurt seeping through your voice. atsumu’s eyes widen.
“i was bein’ a dumbass, i should’ve known from the start. but i can’t stand watching someone else touch ya,” atsumu explains, trying to step towards you. you take a step back, keeping an arm between you two for distance.
“look, atsumu, i think you’re a good guy,” you start, trying your hardest to find the best possible wording. “but i don’t think we’re compatible.”
atsumu’s eyes widen, hand falling to his side.
“what?” he asks, voice going small. you really do feel bad, but decide to continue.
“you’re a good guy, even though you have your flaws. but i can’t do this with you,” you find your flow. “this is toxic. if we truly liked each other we would’ve committed to each other a long time ago. there’s a reason we’re not in a relationship right now.”
“i told ya it’s because of volleyball-“
“that’s not an excuse,” you cut him off gently, but firmly. his voice dies in his throat. “if we really liked each other, we would’ve found a way to make it work. i get it, you have a volleyball career to think about. but i can’t sit around waiting for you to be ready. and besides…”
you trail off, thinking about the other twin who showed you an immense amount of kindness and consideration today. the twin who dragged you out to the middle of a crowded party, and practically declared himself yours without even having the title.
“you should want to be with someone who doesn’t bring out toxic tendencies. you should want to be with someone who you can easily commit to, who you want to show off to everyone.” you explain. atsumu seems at a loss for words for once.
“but i do want you. i want to make ya mine and show you off to everyone here,” he tries to protest, and you shake your head in response.
“no you don’t,” you counter. “i think we should end this. i think you’re a good guy atsumu, but let’s be friends, nothing more.”
atsumu’s face is absolutely crestfallen at this point, and he’s gone fully silent. you wait for a moment, trying to see if he’ll say anything. when you’re sure that he’s going to leave without a word, he decides to speak up.
“okay,” atsumu says, letting out a sigh. you give him a look of surprise.
“you deserve better, y/n,” he says sincerely, voice cracking slightly. “you’re right, you deserve someone who’s going to show you off from the start. i hope you find that, and i’m sorry that couldn’t be me.”
your eyes start to well up slightly and a lump forms in your throat. neither of you speak for a moment, too afraid of letting the dam burst.
you move in to give atsumu a hug, arms circling his back and face burying itself in his chest. his face drops into the crook of your shoulder as the two of you clutch each other tightly. a few tears slip from your eyes, and you feel a couple wet drops on your shoulder as well. both of you stay in that position, saying a silent goodbye to the past few months of seeing each other. finally, after an eternity, you let go of each other and pull back.
you wipe your eyes with the back of your hand, stepping away from atsumu. his eyes are rimmed slightly red.
“bye atsumu, i hope you find what you’re looking for.” you repeat. he nods.
you take one last look at him before turning and heading out of the room. you shuffle down the stairs, feeling surprisingly lighter and better.
besides, now that you had dealt with that, you knew exactly what to look for.
you frantically scan the house from the steps, trying to find the familiar head of ash gray hair. there was no sight of him, making you huff in frustration. however, you did spot a certain brunette that might have the answer you were looking for.
“suna!” you call, shoving your way through the hoards of drunk people around you. said man turns around, eyes widening a fraction at your state.
“are you okay?” he asks, concern taking over his face.
“i’m fine,” you wave him off. you’re sure your eyes are tinged red with the aftermath of the few tears that escaped, but you can’t find it in you to care. you were on a mission. “where is osamu?”
“he left to his house like 10 minutes ago. but why are you-“
“thanks rin!” you interrupt, turning around to fly out the door for the second time that night. at one point, you would sit suna down and catch him up on everything, but right now you were focused on one thing and one thing only.
you sprint down the street as fast you can in your heeled boots, making your way towards the miya household. eventually you reach, breathing hard and hunching over at the porch. you bring a fist up to the door, banging on it hard.
after a few moments, there’s no response, prompting you to raise your fist and bang again. you keep doing this over and over until you hear a voice from inside.
“WILL YA CALM DOWN YA SCRUB! NOT MA FAULT YER A DUMBASS WHO FORGOT THE KEYS AGAIN-“
osamu swings the door open to see you, taking him by surprise. you, still hunched over and catching your breath from the embarrassingly short jog from ginjima’s house.
“i- oh.” osamu says quietly, still standing in shock. “i thought you were my brother.”
“i figured,” you roll your eyes, wincing as you straighten yourself and prop one arm on the doorframe. he watches you silently, unsure of what to say.
“can i come in?” you ask, after the two of stand for a bit in awkward silence. he nods, and moves to the side to let you in. you nervously walk in, unsure of why you were so anxious to come in when you were here an hour ago. osamu stands as you take your boots off, fingers trembling as you unzip them. after you’re done, he leads you over to the small couch, sitting down on one end. you follow his lead, sitting down on the other end. this leaves a solid 2 feet of space between you.
both of you stay silent for a bit, as you look around. the miya house is cozy, nothing too big but well decorated by their mother. there’s a few plants and a nice lamp in the corner setting a dim ambience. the tv is playing professional volleyball match highlights, with a half eaten box of takeout on the coffee table. there’s a few pairs of shoes by the door and a discarded hoodie on the corner chair, which will no doubt earn the boys a light scolding later.
you turn back to osamu and open your mouth to say something, but he beats you to it.
“did you and atsumu work things out?” he sounds almost strained, even though his intentions are good. you wince, trying to think of a good enough answer.
“yeah, we did,” you eventually settle on, watching as his face falls slightly. you’re quick to backtrack. “but not in the way you think.”
he perks up slightly, raising an eyebrow in curiosity.
“how so?”
“i ended things with him.” you admit, watching his eyes widen to the size of saucers.
“what?” his mouth drops in disbelief, staring at you like you grew three heads.
“i mean, did you expect me to put up with the disrespect?” you get defensive as he nods slightly in understanding.
“i get that, just surprised me because the two of ya have been together for so long,” he explains.
“but that’s the thing,” you sigh. “we were never together. atsumu is right, we were never exclusive. we didn’t like each other enough to want to push for a relationship, and we were stuck in an endless cycle of fighting and making up. i’m sick of it.”
he lets you rant, staying quiet as you vent the feelings that have been bubbling up for quite a while now.
“atsumu and i agreed to end things mutually. hopefully he finds someone in the future who he doesn’t have a problem actually dating.” you say honestly, truly resolving any bitter feelings towards atsumu.
“you should too.” osamu adds after a moment. you glance at him, at his gray hair that looked impossibly soft and matching eyes that you could stare at forever. you unknowingly scoot closer to him, closing the gap between you two. he does the same.
“i know,” you respond softly. “i’m done dealing with disrespect. i want to be with someone who wants to show me off, and has no problem committing to me. someone who’s will only ever show me kindness.”
you allude to his earlier actions, and his breath hitches slightly. you debate internally about what you want to do next, before deciding, fuck it, you’ve already done so much tonight. might as well finish the job.
you shift onto your side, before swinging a bare leg onto the other side of osamu’s lap. he lets out a strained sound of surprise, catching you by your hips to steady you. you sink down onto his lap slowly, hands settling behind his neck. the two of you settle in that position- pulses racing, faces warming. your eyes scan his face, tracing over his pretty features. he does the same to you, as both of you try and decipher what the other’s next move is.
finally, he lets up.
“i haven’t been honest with ya,” he murmurs, one of his hands leaving your hips to push some hair out of your face. your heart stutters, and you lean into his touch.
“what do you mean?” you ask, entranced by his stare. he groans quietly, eyes shutting.
“i’m bein’ selfish. i said i wanted to help ya today to get back at atsumu and get his attention, but that’s not true.” he admits. your eyebrows furrow, but you stay silently and let him speak.
“i’ve liked ya for so long now,” osamu confesses, making your heart almost stop altogether. “i’ve liked ya since we were in middle school and you would sit in front of me in class and bring out 10 different colored pens to take yer pretty notes. and i would ask you to borrow pens just so i could have an excuse to talk to ya.”
you can’t believe what you’re hearing. this whole time, osamu has liked you. you, too busy being messy with his brother to even realize.
“i’ve liked ya since i would bring onigiri to school and offer them to you, just to watch ya eat my cooking.” he continues. “even after you started seeing my brother, i liked ya so much i invited you to all our games, even though it broke my heart to watch you wear his jersey.”
your face was flushed red at this point. his thumb was rubbing circles on your hip, other hand firm on your cheek.
“i thought you were doing that for atsumu,” you sputter out. he shakes his head.
“i told ya, i was bein selfish. even today, i said i was doing all this to help you out, but really i just wanted to be with you.” his voice drops to a deep octave, his sexy kansai drawl sending waves of heat through you. suddenly, it was all too much and you couldn’t hold back any longer.
you pull him in by the neck and plant your lips straight onto his, moving your lips with a newfound fervor. he stills in surprise, before relaxing into the kiss and angling his face to deepen it.
his hands circle your waist, pulling you impossibly closer as the two of you practically mold yourselves together, moving in tandem. there was an air of desperation around you, small moans leaving your mouth when his tongue slides across your bottom lip. you move your hands to his hair, tugging slightly at the soft strands. he bites your lip softly in response, forcing a gasp out of you.
you shift your hips further up on his lap, dragging them straight over his crotch. he groans, making you smirk against his mouth as you reach for his shirt and start tugging. before you can get what you want though, he’s pulling your hands away from his shirt and gently pushing you away.
you stare at him in confusion as he does this, almost whining at the loss of contact.
“sweetheart, you make it so hard for me to say this but we shouldn’t,” he tells you. your face falls, heart dropping.
“oh.” you respond with a quiet voice. but before you can climb off him, he stops you.
“i want to do this properly,” he says softly. you look back at him, interest piqued again.
“what do you mean?”
“i don’t want to put you through the same thing my brother did. first, i’m gonna have a long conversation with atsumu about this. don’t wanna sneak around his back, he’s still my brother.” he explains, and you nod in agreement. you never want to hurt atsumu, and you don’t want to start anything with osamu feeling guilty about that.
“then, i’m gonna give us time to become good friends and let you get over atsumu,” he continues, surprising you. “those feelings don’t go away overnight, but i’m gonna help ya through it and make sure you heal.”
you feel your heart swell at that. this man has liked you for so long, yearned for so long, and he’s still willing to wait for you. no one has ever considered your feelings like this before.
“then, i’m gonna ask ya on a date,” he declares. you feel your heart jump. “you deserve to be dated properly. so i’m going to take ya out again and again, and after one of those dates i’m gonna kiss you again.”
“i’m gonna make ya my girlfriend and i’m gonna do it the right way, got it?” he asks, pressing his forehead to yours.
you can’t believe you got so lucky to have this boy like you so much. you gaze at him, his expression determined and earnest. you could tell his heart was set on treating you right, and you almost feel the tears bubbling back up. you nod fervently.
“ok.”
notes: LADIES!!!! NEVER EVER SETTLE FOR A MAN WHO CAN’T COMMIT. know your worth because you are a bad bitch who deserves everything! i know i made atsumu sort of a villain in this story which is ooc but the lesson is to not tolerate disrespect because there will be someone who treats you so much better like the queen you are :))
