#im a little nervous about posting an outline bc mine tend to be...messy?

[silentoathprincess]

whoops i moved houses and completely forgot this post existed. outline is posted under the cut bc its looong

heads up for  sexual content i guess??? its not detailed

headcanons to get out of the way first: 1. instead of sei moving rens consciousness to his body he moved it to one of those clones that were mentioned in… vitri route i think? 2. sei was forced by virus/trip/toue to use his powers on people sometimes under threat (like they would hurt him or smth) and the light-based drugs in the club/the ones mizuki were under came from sei against his will 3. sei and aoba are test tube babies so one could argue their hair was connected based on supernatural circumstance and they don’t actually have the same dna. same with ren like if his consciousness could change the body’s appearance call it fictional magic and sprinkle that in if you’re uncomfortable with potential incest lmao

chapter 1

this au sorta mixes and mashes all the routes together. sei and ren are both in the hospital recovering after everything. aoba visits and tells them of his polyamorous relationships with all the bfs. rich kid noiz can buy them all a big house or smth idk idk. 

theres some disability themes running throughout the story with sei like he’ll probably never walk unassisted again and he falls asleep often but hes happy to be alive and experience new things. he likes being cuddly with ren, they’re both physical people.

when they are well enough to leave, aoba invites them both to the bf house and they agree. its implied that they will be added to the bfs. aoba and sei have been flirting but they like to tease enough that nothings actually happened yet. 

well when aoba makes that offer, seis like “hmm ren you’ve only slept with aoba in scrap and i never had the chance to try it while trapped in the tower. do you wanna try it together?” YES ren absolutely does. its nothing more than kissing and frotting but they both feel more confident after.

add in some comparisons of their unique situations and how helpful it is to share their experiences with someone. especially when it comes to disability and things like their lack of socialization etc etc.

chapter 2

they move into the bf house! ren adjusts quickly bc even though he was an allmate he still met all these people. sei struggles because he only knows them through screens. its very overwhelming and he’s still having to deal with the effects of everything he was put through in platinum jail

he’s in a wheelchair most of the time. its motorized in such a way he can control it using scrap. he sees it as like its HIS power so why shouldn’t he use it? he also mentions being able to see things related to scrap, like glowing light around aobas throat. it makes some of the others uncomfortable tho, koujaku in particular (he thinks sei can see the echos of the beast and this comes back later)

mink is the easiest to be around bc hes calm and doesn’t require a lot of talking. one night sei nods off on his shoulder and, unexpectedly, mink puts and arm around him and lets him doze. when it’s time to go to bed, mink asks if sei wants to come sleep in his bed with him and sei agrees.

they have a heart to heart. mink basically asks if sei is frightened to be with him because of what mink did to aoba and sei is like “no. i did some terrible things myself when i was trapped.” im not sure how to convey it in an outline but sei understands that mink was desperate for retribution and willing to do anything to get there. sei was the same way. they both planned to kill themselves after. PARALLELS.

they end up sleeping together. its a chance for mink to get to treat someone gently after feeling like he couldn’t for so long. its an opportunity for sei to receive gentle treatment after a lifetime of being treated like an object. its very sweet and sappy etc etc

chapter 3

sei gets full length leg braces and arm crutches. noiz manages to rig them in such a way that sei can control them with scrap too. don’t ask me how, i didn’t get that far. sei can stand and even walk a little on his own now! he still can’t do it for long periods of time but thats ok.

sei and noiz start bonding over some shared stuff. i think its outdated (the game IS like 12 years old) that noiz just uuuh completely overcomes his inability to feel pain and thats the end of that. i think theres a way where you could argue that scrap got rid of a MENTAL block but noizs sense of pain is still different than normal. same with temperature. he and sei can keep the disability narrative running and also bond over things like electronics lmao. noiz is definitely the one who acts the most normal about sei being disabled

theyre playful and a little unserious. sei asks about noizs piercings and he gives the whole spiel about how they didn’t hurt except for the one in his tongue. he asks if sei would get any but sei doesnt like needles. he mentions that his dick is pierced tho and sei is like oh…can i see it? and then he gets ideas about what it would feel like and things escalate into sex. 

i don’t know where to mention it but throughout the story sei (and aoba, at least) visit mizuki in the hospital. things are uncomfortable between sei and mizuki bc they both went through some rough shit and there were points where they caught each other at their worst without ever really knowing each other. this will also come back later.

chapter 4

clear has been a little skittish around sei this whole time because sei has more knowledge of the alphas than the others do and he doesnt want to risk being compared to them. he LOVES being helpful with sei though! it makes him feel important! sei notices and honestly? its pretty cute. he starts asking clear to do things like get stuff down off high shelves for him just to get him to come out of his shell.

there’s a sweet moment between them when sei notices the difference in skin on clears face from when he was wounded. clear gets nervous and tries to brush him off but sei is like no its ok. look here, i have scars and things to. its like that. its very (imperfectly) human. clear really takes that to heart. sei has been treated as less than human for a long time and he can relate to how clear feels. he could technically be considered inhuman too.

something something insert joke about clear having a big dick here BUT more importantly than that clear likes to connect with people physically because its one of the ways he feels the most human (same with ren–they struggle with the communication parts ((implied autism anyone?))). long story short he and sei end up sleeping together too. i think i had something in here about sei receiving his first bj from clear bc a robot bf doesn’t need to breathe lmaooo

chapter 5

sei finally confronts koujaku about avoiding him. he knows that its about the beast and YES sei can see him but hes not afraid of him. koujaku still tries to get out of the situation but sei isnt having it. they have to have some tough conversations. its a lot of like…koujaku hates that piece of himself and tries to hide it but he cant from sei. he’s hurt people before and hes like i could hurt you too. theres a GREAT little moment where sei is like you can’t hurt me–im stronger than you. ive hurt people before and i could hurt you if i wanted. like he gets a little scary with it its fun.

once theyre past the harder stuff sei mentions that usui is still around too. shes not separate the way ren and aoba (and desire, as we’ll see later) are, but closer to a more controlled version of koujakus beast. its just more parallels of them like being able to understand each others unique situation and learning to trust each other even when they dont trust themselves

when koujaku and sei end up sleeping together they get to explore that. i dont remember what it was but koujaku says something to sei about being in his lap (like riding him) and sei is like id like to try it but i cant stay on my knees for long like that. but yknooow if you let that beastie loose just a little you could probably hold/move me. it’ll be fine i’ll keep him in check. koujaku is nervous about it but does it. in return sei lets usui out a little too and koujaku feels it as like phantom hands touching him everywhere and hes kinda into it.

chapter 6

aoba and sei are still flirting but you thought it was aobas turn? WRONG its mizuki. theres some backstory stuff happening but the long and short of it is that mizuki gets invited to come live in the bf house too and join them. hes still got some problems that he (and the others) have to deal with and its not the smoothest start but things will work out ok.

as a side note, when aoba first had to explain all of the supernatural stuff that happened to mizuki he…kind of already knew about it. he admits that he knew desire (before the memory wipe) and that they had a sort of more-than-fwb but not-quite-dating thing. 

sei and mizuki definitely have the roughest start. at first they can just kind of avoid each other but after a while it starts getting really obvious and they have to work through their issues. this is actually the heaviest chapter in the piece because theyre both terrified of being know by each other. like sei was witness to mizukis desperation and the fear and harm he brought to aoba etc etc. mizuki was witness to sei being willing to sacrifice and hurt others for his own self preservation. they both saw each other at their lowests and they cant hide or pretend any of that didnt happen and thats fucking scary.

its a lot of almost-tears and generally being afraid of each other and hating themselves until they like. help each other out with it? something similar to the last chapter where theyre like i will trust in you because you dont trust in yourself. things get physical between them as a way to both self soothe and comfort each other. i really liked this one because mizuki gets a little desperate to please and ends up presenting as pretty submissive. even though mizuki still tops in this one sei kinda gets this idea that mizuki would defs let him top if he asked and you bet he stores that shit away for the future lmao

chapter 7

its finally aobas turn! after all the teasing they finally get to have sex lmao. in direct opposition to the last chapter, this ones nothing but fun. its pretty casual the whole way through. sei and aoba get to spend a day on the town first. seis excited to 1. explore this new place with someone who knows it really well and 2. get to go on an actual date. aobas psyched too he likes how happy and full of life sei is, especially when he was planning to go down with the tower not that long ago

aoba and seis storys could have been exactly the opposite if aoba would have cried first when they were born right? theyre both very aware of it. their stories still have a lot of similarities regardless. this whole thing is a way for them to make up for lost time and get to bond with someone they both thought they would never meet.

when they head back they know that they’re finally going to sleep together. the way aoba initiates things is pretty casual too. like theyre doing their whole fun flirty banter thing and aoba grins and straight up asks if sei wants to have sex. seis like yes! finally! its a lot of fun and laughing and fucking things up in silly ways. he encourages aoba to top and aobas like “really? id like to but i havent gotten a chance yet. the others always get the jump on me.” aoba’s still a noisy top. he and sei both get a little whiny lmao

chapter 8/bonus chapter

when sei wakes up the next morning he and aoba are still in bed. he can tell immediately from aoba’s aura though that its not quite aoba. he says hello and this other person says hey back. sei asks what he should call him and the other person says “desire.” they talk for a moment until sei is like dont you want to go out and see the others? ren? mizuki? admittedly desire isnt sure how ren will react to him but since he and mizuki used to be almost-an-item he for sure does want to see him

sei convinces him to come out of the bedroom and lets the others know that its desire. he and mizuki get a moment where mizuki is like “desire?” and desire loses all his inhibitions. he leaps into mizukis arms and almost knocks him over but theyre laughing and kissing and everything is good.

they go through the day of desire getting to interact directly with everyone but since this is a sei focused story he does come back to sei at the end of the day. hes like “hey since you encouraged me to show myself again i wanna spend the night with you.” desire isnt afraid to get a little rough with sei (and let him get a little rough in return). its nothing extreme but after being treated gently for so long sei likes that he can try letting loose and having a little more fun with experimenting. 

id love to add in a bit at the end with everyone! just all of them enjoying each others company and spending time together. since getting struck with the idea for this au ive also come up with some side stories for it but theyre not all sei focused lmao.

thanks for reading!

ooooh man i had such a great idea for an au where sei joins all the polyamorous dmmd bfs and it like goes through his relationship with each of them and all the similarities in their stories and i am FIGHTING myself not to write it right now
