Hello! Iâm so happy about how my request had turned out! I noticed how you said you would live some poly seijoh requests... that wouldâve have been apart of my last one but I didnât think you wrote for that. So! What Iâm saying is, how about you write some of your own poly seijoh headcanons! Anything youâd like! I really love those boys and would kill to read it! đ€đ€
Hi!! I loved writing these so much oh my god!! I also added to my rules that Iâll write for poly relationships!! I kind of went a little bit overboard with this, and I wasnât 100% sure about how to end it, but I hope you enjoy!! I tried to write an equal amount about each boy but I feel like I didnât write as much for Iwa but oh well. And thank you SO MUCH for requesting them I love them so much!!
Word Count: 3000 words (...yeah)
Warnings: some timeskip spoilers, proceed with caution if you donât know their timeskip occupations
Youâve all been very good friends since first year, and are practically inseparable
Since youâre all a pretty popular friend group, there are a lot of people who have crushes on you guys and end up confessing
But none of you ever end up accepting any confessions, which leads to some rumors about how youâre all hooking up or how some of you are dating
And I mean the rumors are at least a little bit based in reality; I mean no one can miss how Makki and Mattsun walk around with their pinkies practically interlaced, or how Iwaizumi always buys you and Oikawa lunch and snacks, or how Oikawa stares at Makki in class when he thinks no one is looking, or how Mattsun teases you in the hallways, or how you all borderline cuddle in public whenever one of you have a bad day
Youâre all hanging on a precipice between friendship and dating, and everyoneâs too terrified of making a move and risking âthe end of your friendshipâ (even though I donât think any of them would actually end a friendship over a crush)
One night after their practice, youâre all hanging out at Oikawaâs house
The fast food you got earlier is strewn all over the coffee table, and everyoneâs draped all over the living room furniture while you watch (heckle) shitty horror movies
Oikawa is sitting in Mattsunâs lap, Makkiâs head is on your thighs, Iwaizumi has his arm flung over your and Mattsunâs shoulders
Itâs somehow both incredibly calm and comforting, as well as tense
Out of basically nowhere, Mattsun picks up the remote and pauses the movie
âHey, is everything ok?â Iwaizumi asks, clearly very concerned.
Mattsun just sucks in a deep breath
âHey, I really like you guysâ he finally says
âUh yeah I sure hope so? Weâre best friends it would kind of suck if you couldnât stand usâ Makki laughs nervously
âNot like that dumbass. I mean I like you like I want to be able to hold hands with you guys and kiss you and go on dates that we actually call dates instead of just âhang outsâ you know?â
Everyone breathes out a breath you didnât realize you were holding
âOh thank god, I was so worried I was reading all the signs wrongâ Oikawa says
You just kind of sit in silence for a little longer, itâs a lot to process! You just found out that your friends all want to date you, and you want to date them too!
âSo...does this mean weâre all...dating now??â
Everyone just kind of nods in agreement and in an incredibly anticlimactic fashion, you all just go back to watching the movie
So now youâre all officially dating!
Literally no one at school is surprised
Going from a platonic friend group to a romantic polyamorous relationship is incredibly smooth
Itâs basically the same as it was before, but now you hold hands walking around school, and you kiss each other goodbye, and you finally get to tell each other how you feel about them whenever you want, and Oikawa stares at Makki in class without caring about whoâs watching (once they got detention because they were literally blowing each other kisses in the middle of Calculus. You and Mattsun found it absolutely hilarious. Iwaizumi was not amused.)
You also all had a pretty long talk at the very beginning about boundaries (communication is super important especially if your relationship has more than two people!!)
Everyone is on a different level of comfort when it comes to PDA, but theyâre all ok with at least some of it
Oikawa is the most comfortable and oh my god he is so clingy
He will literally drape himself on top of you in public if he feels like heâs not getting enough attention
Hanamaki is in second, he has no shame and he really likes physical affection (I think one of his main love languages is physical touch) and heâs also really flirty (but more in goofy way)
He tends to stick to holding hands and cheek/forehead kisses, but he will occasionally pick you up and kiss you all over your face while calling you his âpersonal ray of sunshineâ to make you giggly and embarrassed
Matsukawa is in third, he is also pretty shameless but he does prefer being affectionate at home and in private
He does almost always have his arm around someoneâs shoulder or waist, and sometimes heâll just hug you from behind and rest his head on your shoulder while youâre in the middle of a conversation
Iwaizumi is the least comfortable with it, but he still likes it!! Heâs just worried that heâll end up making the people around you uncomfortable if youâre all too affectionate
He likes it when you lay your head on his shoulder whenever youâre both sitting down
Also, because thereâs so much communication and because youâve all been close to each other, thereâs almost never any jealousy or fighting
Even when there are arguments and fights, itâs almost always resolved by the end of the day, and there are no hard feelings after the fact
You all go on dates every weekend! Oikawa likes going on super fancy and romantic dinner dates, Hanamaki likes amusement park dates, Matsukawa loves arcade dates (once you all had a laser tag date and it was incredibly fun but also so competitive that you almost got kicked out) and Iwaizumi actually really loves museum and aquarium dates
Whenever you guys donât really feel like going out for a date you just watch movies together at home while cuddling
Once Iwaizumi tricked Mattsun and Oikawa into studying by promising a âstudy dateâ which actually just ended up being Iwa yelling at both of them to focus
Also sometimes some of you will go on dates with only two or three of you (you all have a groupchat, and everytime thereâs a date like that everyone on the date spams the groupchat with cute date pictures)
Pet names! There are so many pet names!
They use such a wide variety of pet names on you and each other, Iwa usually sticks to the classic ones like baby, Makki calls you sweetheart (both in a genuine way and to be a little shit), Mattsun calls you gorgeous/handsome, and Oikawa has SO MANY names for you (sunshine, prince/princess, angel, my love, etc.)
Once Mattsun called Oikawa his âhandsome princeâ as a joke and Oikawa blushed SO hard (he never lived that one down)
Whenever you all have sleepovers it is so soft and wholesome oh my god
Theyâre all so so cuddly
Oikawa is definitely a little spoon BFDBGBSG he just really likes being held! He genuinely loves how safe and warm and at home he feels in your arms
Hanamaki likes sleeping on his stomach with his head on your chest so he can hear your heartbeat
Matsukawa is a little bit of a starfish, so heâs always just super spread out. He usually ends up just kind of draping his limbs on top of everyone else
Iwaizumi sleeps like a koala! He will fully wrap his whole body around one person, and itâs somehow both incredibly comforting and a little bit suffocating
It doesnât really matter how you guys are positioned when you fall asleep, when you wake up in the morning youâre all just a huge tangle of limbs
Getting up is a challenge because in addition to being stuck in the middle of a bunch of ridiculously tall dudes, you have to deal with Iwa holding you hostage and Oikawa whining about how he just wants to stay in bed all day
Makki is absolutely the type of person who would fart and trap you under the covers while cackling maniacally
Mattsun has the WORST morning breath but he also loves sleepy morning kisses
When Oikawa wakes up before you, he likes to turn around in your arms and play with your hair and watch your face, he just thinks you look so peaceful and happy in your sleep!
Lazy mornings with them are the absolute BEST you can not convince me otherwise
Even after youâre all awake, you all just stay in bed cuddling until someone has to get up to pee or youâre just too hungry
Mattsun is such a good cook! He makes everyone a really nice breakfast!
Oikawa helps him out by decorating all the food, he definitely knows how to cut fruits into like flower shapes and all that fancy shit
Once graduation rolls around, youâre really worried that youâll all grow apart and break up once youâre all in college and actually working
But theyâre all quick to reassure you that they all love you so much and theyâre all willing to try and make the relationship work
You all go to college pretty close to each other, so instead of moving into a dorm, you just get an apartment together
Some of your parents are worried that youâre all moving too fast, and that youâve only been together for just over a year, but youâve all been this close for such a long time that moving in together just feels natural
Speaking of parents, not all of your parents were really 100% accepting of this relationship
But over time, everyone can see how happy you make each other, and eventually accept it
So anyway, now youâre all officially living together!
It doesnât really change your relationship much, besides doing chores and getting ready in the morning together
Everyone divides up chores pretty evenly between the five of you
Matsukawa still cooks for everyone, and sometimes if heâs feeling really sweet heâll pack lunches for everyone
Oikawa usually requests being on laundry duty, something about it is super comforting and relaxing for him
Getting ready in the morning is...interesting to say the least
Iwaizumi wakes up at the asscrack of dawn to go for a run, and usually drags Oikawa out of bed to go with him
Mattsun gets up around half an hour later to make breakfast
Makki stays in bed as long as possible, usually until Mattsun announces that breakfast is ready
Oikawa and Iwa get home sometime while Matsukawa is in the middle of cooking, and take a quick shower (once they did not shower before breakfast and the rest of you complained about how much they stank the whole time BFGFBFDBGH)
You all sit down to breakfast and talk and laugh and joke around until someone points out that youâve all gotta leave in twenty minutes
After that itâs a mad rush to get dressed, brush your hair and teeth, and do the whole rest of your morning routines
On weekends or any days where youâre all free, itâs a lot more relaxed, Iwa and Oikawa stay in bed with the rest of you until past 10 a.m
Also speaking of showers! They all really like taking showers with you (NOT in a sexual way, itâs just really cute and domestic) as long as youâre comfortable with it!
When Oikawa tells you all that heâs moving away to pursuit volleyball, he is in tears, and heâs terrified that your relationship wonât work out while heâs so far away
But you reassure him that youâll all still love him no matter how far away he is
Long distance actually works out really well for you all
You keep the group chat going strong in his absence, you all send him pictures of your lives and he sends some back!
You also videocall him almost every single day
It feels almost as if heâs never left, since heâs still so involved in your life
He visits whenever he can, which is not as often as youâd like, but you all make the most of it
The years pass, youâre all still together, Iwaâs still lecturing Oikawa for staying up too late, Mattsunâs still making shitty puns constantly, Makkiâs still posting the goofiest candid photos if everyone else, and you all love each other so much
Iwaizumi is such a stable and comforting presence, always checking to make sure that youâre feeling alright, holding you whenever you cry
He is pretty busy helping out the Japan team though, and Matsukawa also has work, so if youâre ever at home during the day youâre probably hanging out with Makki
Mattsun and Makki are constantly teasing each other about their respective professions (or lack thereof)
âOi Mattsun, whatâs it like spending your whole work day with dead people?â
âOi Makki, whatâs it like spending your whole work day-oh wait.â
When the Olympics roll around, you, Matsukawa, and Hanamaki go to support Oikawa (and Iwaizumi)
He looks a little bit nervous before the game, but the second his eyes fall on the three of you sitting right at the edge of the court, he visibly relaxes
The whole game, everyone around you is staring at you because of how loud youâre cheering, but youâre just so proud of them!
You take a moment to think about how much those four have changed since you met them as first years so long ago. If someone told you at that point that you would end up in a strong romantic relationship with them, you wouldnât have believed it, but now looking at the guys you love, it feels like the most natural thing in the world
You canât believe how far youâve all come, and how happy you all are
When Oikawa finally sets up for the winning point, you all scream and run outside to meet up with him and Iwa
You run into Iwaizumi first, who tells you about how Oikawaâs swamped with fans
When you finally find him in the middle of a crowd, he makes eye contact with you and smiles, pushing through the crowd and coming straight for your little group
He pulls all four of you into a big group hug, everyoneâs laughing and crying and taking pictures and screaming as you all just hold onto each other
Oikawa breaks the hug first, and takes a few steps back, before getting down on one knee
