title: bathroom secrets

rating: mature

genre: abo / teen angst

fandom: haikyuu!!

setting: early 2000s, oakland, california

current situation: senior year of high school

plot summary:

everyone knows high school runs on a hierarchy. cliques, labels, reputations—you name it. at the top? the populars. you’ve got kuroo tetsurou (o), our self-proclaimed princess and reigning cheer captain. and then there’s bokuto koutarou (o), the golden boy with a smile bright enough to light up the whole gym. oh, and don’t forget the athletes—oikawa tooru (a) and ushijima wakatoshi (o), volleyball captains and literal gods in the eyes of half the school.

but that’s only the one percent. the rest? welcome to the nerds—like daichi sawamura (o), class president, number one student, and basically a walking valedictorian speech. his sidekick? sugawara koushi (a), the vice president with actual social skills. and somewhere behind the camera you’ll find akaashi keiji (a), our news reporter-slash-photographer, watching it all unfold through his lens.

then there’s the stoners. not many, but trust me—you’ll smell them before you see them. word is, if you want the good stuff, you go to kozume kenma (b). or tendou satori (b). he’s the one who somehow manages to sneak it past security.

and finally… the bottom of the pyramid. the loners. or as everyone else calls them, the losers. like iwaizumi hajime (o)—the kid who’s been bullied since he set foot on campus, and never managed to climb higher than the floor.

but here’s the thing about high school: secrets don’t stay buried. drama doesn’t care about cliques. and sometimes, the people you least expect? they end up becoming your ride-or-dies.

take kuroo, bokuto, daichi, iwaizumi, and tendou. right now, they couldn’t look more different. but in a few years? they’ll be closer than family.

how does it all start?

simple.

an abandoned bathroom.

and the hunt for a pregnancy test.

kuroo tetsurou ((o) the princess 👑)

age: 18

appearance: hazel green eyes, 6’1, 75.3 kg (166 lbs), slim pear-shaped build, olive-toned skin, lots of moles (esp neck), heavy eye bags (covered w/ makeup), contacts at school, glasses at home

favorites: baby pink + red, sushi (pregnancy restrictions win, sorry), britney spears, doesn’t really read

habits: no smoking, social drinker (parties only)

hobbies: cheerleading, makeup, fashion, sewing/upcycling, thrifting, decorating, dancing, going out (social butterfly 🦋)

background: born in cambridge, ma. parents fought constantly → messy divorce. moved w/ dad (o) to oakland to live w/ maternal grandparents. childhood after move = pageants, dance, cheerleading, confidence building.

problems: pregnant w/ ex’s (daishou suguru (a)) baby. he’s abusive + already dating yamaka mika (o).

endgame: kozume kenma (b), next door neighbor + seatmate

clothing analysis:

kuroo doesn’t just wear clothes—he wears statements. color is his love language: pinks, reds, jewel tones, anything that makes people stare (and they always do). his style lives in that perfect blend of y2k revival and luxury brat aesthetic—short skirts that barely pass the dress code, crop tops in every shade, thigh-high socks with rhinestones or lace trim, mini leather jackets that look custom-made just for him. think maddie perez drama, london tipton boldness, and just a sprinkle of regina george’s bite.

pregnant or not, kuroo refuses to tone it down. no maternity wear, no “dressing for comfort” —he’s too much of a bad bitch to compromise. if anything, he makes the bump part of the look, throwing cropped sweaters over low-rise skirts, or wearing bodycon dresses that make sure nobody forgets he’s the moment.

accessories are a religion: statement earrings that could cut glass, layers of delicate gold necklaces stacked with pearls, nails always painted to match the day’s fit, and makeup that pops (red liner, glitter shadow, glossy lips—he’s not afraid to experiment). he’s got designer handbags, rhinestone phone cases, and hair clips shaped like cherries or hearts that somehow never look childish, only iconic.

bokuto koutarou ((o) the golden boy gone wrong 🌻)

age: 18

appearance: yellow-brown eyes, 6’0, 78.3 kg (172.6 lbs), athletic w/ chunky thighs + hips, light tan, freckles (nose, shoulders, thighs, knees)

favorites: yellow, light blue, soft purple, japanese curry + steak, no fav books (dyslexic), listens to everything except country

habits: smokes weed rarely, drinks fruity drinks (later quits)

hobbies: volleyball, working out, going out

background: born + raised in oakland’s rich area, second-gen japanese-american. dad (a) neurosurgeon, mom (o) therapist, twin sisters (a) abroad. “perfect” family on the outside → toxic mess inside.

problems: bipolar hypomania, toxic home, abusive relationship w/ akaashi’s older brother (a),.

endgame: akaashi keiji (a), school paper head + photographer

clothing analysis:

pastels. flowy fabrics. soft textures. that’s bokuto’s entire closet—at least, the one his family and boyfriend built for him. pale cardigans, pastel button-ups, linen trousers, soft sweaters in baby pink and mint. he wears them because it keeps the peace, because everyone seems to love him like this: the perfect pastel omega, sweet and harmless, a doll dressed up for display. but ask bokuto how he feels about it? he hates it. every single second of it.

his hair is his only rebellion. streaks of silver, blonde, platinum—messy cuts, uneven layers, glitter dusted through like he’s daring someone to comment. it’s the only piece of freedom he allows himself, the only thing no one else gets to dictate. but clothes? clothes are still a prison, picked to make everyone else happy while he quietly shrinks under them.

he hasn’t found his true style yet, though it’s bubbling just under the surface. kuroo sees it, even if bokuto doesn’t. kuroo’s already plotting quiet wardrobe interventions, slipping him small pieces that feel more bokuto: ripped tanks, cargo pants, grungier sneakers, layered jewelry. slowly, painfully, bokuto starts to realize that he doesn’t have to be everyone’s golden boy in pastel pink.

when he finally breaks free, his style blossoms into something bold, sharp, and unapologetically his. think jadeybird tiktok energy: chaotic layering, edgy streetwear mixed with playful cuts, thrifted finds styled to perfection, oversized cargos with cropped tops, chains and eyeliner and boots that stomp. it’s loud, it’s confident, it’s messy—but it’s him.

tendou satori ((b) the addict on fire 🔥)

age: 18

appearance: very dark brown eyes (needs glasses, refuses), 6’2.9, 71.1 kg (156.7 lbs), tall + lanky, ghost-pale skin, rosacea, acne scars

favorites: red, black, dark red-violet, chocolate desserts, stephen king thrillers, indie/rock/alt (big paramore fan)

habits: smokes constantly (cigs, vape, weed), heavy drinker (even at school), often shows up drunk

hobbies: reading, music, skateboarding, photography, smoking in the empty omega bathroom, sleeping

background: born in germany (dad (a) military). mom (o) left him w/ dad → moved back to oakland. raised by alcoholic grandfather (o) who introduced him to drinking/smoking. grandpa recently died from liver failure, tendou found the body.

problems: addiction, trauma, insomnia, isolation

endgame: ushijima wakatoshi (o), omega volleyball captain

clothing analysis:

tendou’s whole look screams teenage dirtbag with zero apologies. his closet is a graveyard of black and red—oversized leather jackets, thrifted hoodies, old band tees with cracked graphics, ripped jeans that look one wash away from falling apart. sneakers are beat up, soles worn thin, sometimes scribbled on in sharpie from late-night boredom. piercings glint from his ears, and yeah, he’s got a couple of small tattoos he swears are “just doodles” but mean way more than he lets on. a streak of dyed hair—sometimes red, sometimes bleach blonde, sometimes both—stands out like a flag that says yeah, i did this, what about it?

on the surface, his style feels careless, thrown together, like he grabbed whatever was on his floor. oversized layers hide his frame, giving him a silhouette that looks messy but is carefully curated to scream unbothered. but if you look close, every detail is a quiet rebellion—band pins on his jacket, a mismatched belt loop chain, chipped nail polish in black and neon. it’s less about fashion and more about flipping off the idea of blending in.

the irony? tendou thinks no one’s really paying attention. to him, he’s just another burnout beta, written off by teachers and labeled a stoner by classmates. what he doesn’t see is how magnetic it actually is—the way people glance when he laughs too loud in the hall, or how his crooked grin and slouched jacket carry a kind of confidence he doesn’t even realize he’s radiating.

daichi sawamura ((o) the anxious overachiever 📚)

age: 18

appearance: very dark brown eyes, glasses (meant for reading, wears full-time), 5’9, 81.6 kg (180 lbs), chubby oval/hourglass build, super tanned skin, deep dimples (rarely seen)

favorites: sunset orange + dark green, korean bbq, shakespeare romances (esp taming of the shrew), classical music (helps with anxiety)

habits: doesn’t smoke/drink, rarely leaves the house

hobbies: studying, reading, journaling, doodling, astronomy, long walks, sunsets

background: born in miyagi → moved to oakland at 10 for “better opportunities.” became caretaker as parents kept having more kids. childhood full of responsibility + pressure.

problems: anxiety disorder, overworking himself (for others), strained relationship w/ mom (o), oldest sibling syndrome

endgame: sugawara koushi (a), vice class president

clothing analysis:

neutrals, oversized sweaters, baggy pants—that’s daichi’s armor. he doesn’t dress to stand out, he dresses to disappear. his clothes are loose, shapeless, safe, always chosen with one thought in mind: don’t give anyone a reason to look too closely. beiges, greys, washed-out greens, the kind of muted earth tones that blend into the background. comfort over style, safety over statement.

but it’s not just about comfort—it’s about fear. fear of how his mother would tear him down for showing too much. fear of classmates whispering if they noticed his body. fear of being judged for simply existing. so he hides. every day, he hides.

then kuroo comes along with his bright skirts and bold lips and this unshakable belief that you can wear whatever the hell you want and still be untouchable. kuroo doesn’t push—he nudges. a brighter-toned sweater slipped into daichi’s bag. a chain bracelet “accidentally” left behind for him to wear. tiny, subtle rebellions.

and little by little, daichi starts trying. a sweater that clings more than it hides. jeans that fit instead of swallowing him whole. a soft orange knit that makes his skin glow instead of another lifeless grey. a single silver ring on his finger. it’s quiet, almost invisible to anyone else, but for daichi, it’s monumental.

iwaizumi hajime ((o) the hopeless piner 🌊)

age: 18

appearance: seafoam green eyes, 5’7, 70.2 kg (154.7 lbs), rectangle build, bubble butt (hides it), very tan (half filipino, half japanese), vitiligo patches (hands, knees, mouth, eyebrow)

favorites: seafoam green, teal, lilac, ube pandesal + spicy agedashi tofu, percy jackson (not titan’s curse), harry potter, r&b (destiny’s child, aaliyah)

habits: doesn’t smoke/drink (filipino mom would kill him)

hobbies: writing short stories/poems, musicals, reading, drawing on converse/docs

background: born in philippines. mom (o) = young college student, dad (a) = older japanese businessman who left. moved to oakland as baby, raised by single mom. money tight but home full of love. bullied heavily (race, secondary gender, height, vitiligo). childhood friend + crush: oikawa (a). friendship cut off at 14, but feelings stayed.

problems: constant bullying, low self-esteem, unshakable crush on oikawa

endgame: oikawa tooru (a), volleyball captain, most popular guy in school, ex-childhood friend + long-time crush

clothing analysis:

iwaizumi’s style is dark, layered, intentional chaos. black and jewel tones dominate his wardrobe—deep emeralds, sapphires, burgundy—all grounded by ripped knit sweaters that look like they’ve survived a war (some of them actually handmade, sleeves fraying in places he stitched back together himself). low-rise jeans hang loose on his hips, chains clipped to belt loops, his favorite doc martens scuffed to hell but still solid. he’s got piercings up his ears, little silver studs and hoops that catch the light, and a belly button ring that flashes when his sweater rides up, a quiet rebellion that most people overlook.

his sneakers sometimes show streaks of hand-painted designs—stars, lyrics, little doodles that only mean something to him. patches sewn into jackets and bags in uneven stitches, giving everything that diy, lived-in edge. on the surface, it screams i don’t care, but the truth is iwaizumi cares too much. every tear in his jeans, every pin on his backpack, every layered bracelet on his wrist is a piece of armor he carefully puts on before facing the world.

(platonic) relationship analysis:

kuroo & bokuto:

bokuto’s life looks perfect on the outside, but kuroo sees right through the cracks. kuroo becomes bokuto’s anchor, the one person who doesn’t get blinded by the “golden boy” mask or intimidated by kenta’s grip on him. kuroo knows too well what it’s like to be in a suffocating relationship, to feel trapped but too scared to leave. he doesn’t push bokuto—he listens, supports, drops little truths when bokuto’s ready to hear them. kuroo is patient, firm when he needs to be, but never cruel. eventually, he becomes bokuto’s voice of reason, the person who reminds him he deserves more than bruises and excuses. kuroo isn’t just a friend—he’s bokuto’s safe exit plan.

kuroo & daichi:

daichi always saw kuroo as the stereotypical “mean omega”—the cheerleader with claws, untouchable and terrifying. but once they collide in the bathroom, daichi realizes kuroo’s strength isn’t cruelty, it’s survival. kuroo becomes the first person to gently (and sometimes not-so-gently) push daichi to stop hiding behind baggy sweaters and perfect grades. he encourages daichi to take up space, to actually look in the mirror and see someone worth being proud of. when daichi falters, kuroo is there with sharp wit and an even sharper kind of love: “you’re not hiding anymore, sawi. not from me, not from anyone.” kuroo becomes the mirror daichi never had—one that reflects possibility, not shame.

kuroo & iwaizumi:

iwaizumi’s always been the easy target, but not under kuroo’s watch. something in kuroo shifts once he finds out he’s pregnant—his protective instincts latch onto the people he cares about, and iwaizumi becomes one of them. he steps in when cassie or anyone else tries to push iwaizumi down, making it clear that messing with hajime means messing with him. but it goes deeper than defense: kuroo starts nudging iwaizumi toward oikawa, encouraging him to believe that maybe, just maybe, the boy he’s pined after for years might see him too. kuroo becomes iwaizumi’s shield, his strategist, and his cheerleader, never letting him forget that he’s worth being loved.

kuroo & tendou:

their friendship doesn’t click at first—kuroo can’t stand tendou’s constant smoking and partying, and tendou doesn’t like being judged. the breaking point comes when kuroo has a bad reaction to secondhand smoke, sending him spiraling in the bathroom with nausea and panic. tendou sees the real weight of kuroo’s pregnancy then—not the glamorized whispers, but the raw vulnerability. something shifts in him. he starts cutting back, not because anyone forced him, but because he doesn’t want to be the reason kuroo or the baby suffers. tendou becomes unexpectedly protective, slipping into the role of “chaotic older brother” who glares at anyone giving kuroo trouble and always has snacks or water tucked in his bag “just in case.” kuroo doesn’t just scare him straight—he gives tendou a reason to want better for himself.

bokuto & daichi:

at first, it’s awkward. bokuto’s chaotic energy clashes with daichi’s perfectionist, anxious nature. bokuto can’t understand why daichi obsesses over grades and schedules, and daichi can’t understand why bokuto lives like the world’s ending every other day. but late one night, stuck in the library after missing volleyball practice, bokuto sees daichi quietly panicking over a math problem. instead of laughing, he sits down, cracks a joke, and slowly guides daichi through it. daichi’s defensive walls soften, and for the first time he realizes that sometimes, people can be loud, messy, and helpful all at once. they become an odd sort of support system—bokuto teaches daichi how to loosen up, and daichi gives bokuto a sense of stability he didn’t know he needed.

bokuto & iwaizumi:

they bond over shared frustration at being misjudged. bokuto admires iwaizumi’s quiet resilience—how hajime walks through the hallways like he belongs even when everyone whispers. iwaizumi admires bokuto’s raw openness, his ability to wear emotions on his sleeve without shame. late-night volleyball practice, hallway brawls over stupid bets, and mutual defense of kuroo turn into an unspoken camaraderie. they become partners-in-crime, whether it’s sneaking snacks from the cafeteria or staging small rebellions against unfair teachers.

bokuto & tendou:

these two are fire and gasoline. at first, tendou’s sarcastic, “don’t care” energy grates on bokuto’s sunny, chaotic self. but once tendou sees how much bokuto struggles with kenta and family pressure, he softens. they share quiet corners for smoke sessions, talk about what no one else understands, and slowly tendou’s cynical humor balances bokuto’s constant optimism. they become an unlikely duo—bokuto draws tendou out of his shell, tendou keeps bokuto grounded.

daichi & iwaizumi:

mutual respect builds slowly. daichi notices hajime’s resilience, his intelligence masked by alt vibes and quiet sarcasm. iwaizumi notices daichi’s dedication, the quiet courage it takes to carry responsibilities most kids his age can’t imagine. shared study sessions turn into light-hearted banter, and iwaizumi slowly becomes a source of comic relief when daichi’s anxiety spikes. they teach each other patience—daichi teaches strategy and thoughtfulness, iwaizumi teaches boldness and confidence.

daichi & tendou:

daichi is wary at first—tendou’s rough edges, chaotic habits, and substance use put him on edge. but when daichi sees tendou protecting kuroo or quietly looking out for someone weaker, he starts to respect him. tendou’s blunt honesty forces daichi to confront his own fears and self-doubt, and daichi’s calm rationality sometimes tempers tendou’s more impulsive tendencies. together, they balance chaos and order in small, understated ways.

iwaizumi & tendou:

the two alt-types connect over shared outsider status. ripped sweaters, layered jackets, scuffed boots—they notice the little things others don’t. they argue, tease, and sometimes almost fight, but underneath the bickering is a quiet understanding: the world underestimates them. they share spaces in the school that feel safe—skate spots, hidden corners, abandoned classrooms—and slowly a genuine friendship forms, based on loyalty, sarcasm, and mutual protection.

Bottom Daichi 😳 those thighs are something to hold on to 🤤

😈smutty drabble under the cut ↴

but i have new prompt up for adoption!

haikyuu omegaverse and art theft/conman au!

now ik what you might be think “oh it’s just gonna be the same people being omega/alpha/beta” but don’t fret my dear summer child, over here we do things a bit differently but let’s talk about the prompt first before get into the knitty gritty 😗

so here's what i was thinking:

-there are two groups, one with omegas/betas and one with alphas/betas, and both groups deal with jewelry/art/money (ill leave that up to you) heists.

-both groups have the same main focus, so they have a friendly rivalry when they first start (around high school/early college age).

-but after feelings are hurt and heists go wrong, both groups split up. years have passed, and the ob (omega/beta) group went off the grid, but the ab (alpha/beta) group remained in the heist scene. but they haven't had much luck financially, but they are fortunate enough to score a heist that will set them up for the rest of their lives; however, there is one problem.

-you can choose the problem, but i was personally thinking that the plan that created required more people then they had. so as a way to fill in the gap, they decide to go and find (with much difficulty) the ob group and beg for help, knowing that with their assistance, they will be able to do the job no problem.

-but the ob group have one main condition: this would be the only and final heist (you can choose why they ask for this)

-with the now-combined squad, they attempted to execute the heist; but there was a little roadblock in the way .…what was it? you ask, well it was only the murder of the person they were supposed to steal from …😬

-it was supposed to be simple, right? well, not anymore with the police on their asses they wouldn’t need anymore trouble right? .…well tell that to their old buddies who are looking for a…bit of revenge.

-will they be able to find love and hope in between, the blazing guns, car chases, and death? …that’s up to you to choose their fate 🤩

…

now that i scared you, we finally get to the fun part the a/b/o dynamics *laughing maniacally 😈*

drum roll pls….

for omegas we have:

sawamura daichi ☠️

iwaizumi haijime 🦔

kuroo testurou 🐈‍⬛

bokuto koutarou 🦉

(you can add more, it just too many characters to think about 🥲)

betas:

akaashi keiji 🦉

kozume kenma 🐈

(again…ADD MORE IDC)

alphas:

oikawa tooru 👑

sugawara koushi 🍬

now ships

-the usual daisuga, kuroken, bouaka, iwaoi (again add onto it) but i would love to see other ships and some love triangles and couple angst 😏

extra notes:

-i was thinking of a oc! kid (5-6) you can choose the gender, name and parents but i was personally thinking daisuga as the parents to a little boy (idk what to name him) but suga doesn’t know that’s his kid (he’s a bit dumb alright 🙂‍↕️) and its like super angsty between the two of them.

but that’s all for today, again if you do decide to write this fic, please tag me so i can read it pls🥹🙏
