Just Married 2020 Letter

Whatever freeform tag we match on, feel free to use that as your only prompt. While I may highlight some freeforms or grouped freeforms with some fandoms, that's only because there's aspects of the freeform I vibe towards more, while for other freeforms, they're basically self-explanatory so I'll eat up any variation.
General Likes:
-AUs that directly engage with a dynamic of the character interaction or ship, whether it's mundane, fantasy/sci-fi, fusion with another existing canon (requested canons preferred), or other. Social strictures around their engagement/marriage are a plus.
-Unusual formats. If that's what interests you, get creative with your work.
-Genderplay, whether that's gender nonconforming presentation or genderfluid-type identities.
-Pining, especially in situations like arranged or fake marriages where they're constantly in close proximity.
-Outsider POV, especially people who don't know them well (acquaintances or strangers).
Art Likes:
-Obviously we're all here for the wedding photos, so for those ships who'd do big, splashy weddings, go nuts!
-Small moments- when an arranged couple speaks in private for the first time, or when they kiss as a married couple, or proposing.
-Smut-wise, I'm looking for either tender, affectionate wedding night sex or rough, upsetting dub/noncon, no in-between. Focusing on hands or microexpressions are a plus.
General DNWs:
-piss, scat or vomit in any form
-extreme underage
See each fandom for any specific DNWs
Mulan
Fa Mulan/Li Shang
specific DNW: non/dubcon
Future Arranged Spouses are Forbidden To Meet But Able To Study One Another's Hobbies
The question is, is it their real hobbies or is it the hobbies that are societally approved? Because for the latter, Mulan's 'proper' hobbies would be an awkward way to get to know your wife without actually knowing your wife.
Person Mistaken For Mail-Order Spouse and Goes With It
There are a lot of ways this could go, but if you're historically inclined, Mulan could be an accidental picture bride in the early 20th century. Or alternately, her prospective husband sent her Shang's picture instead, so he's the mistake!
Arranged Marriage - partners randomly chosen through government lottery
Character thinks proposal was rejected but other person misunderstood
Characters Keep "Forgetting" to Annul Accidental Marriage
Marriage Arranged Because of Matching Soulmarks
Proposal misunderstood as being for ulterior motives
Zootopia
Judy Hopps/Nick Wilde
specific DNW: noncon. Dubcon is okay.
Character Surprises Future Spouse with Their Family at the Wedding
This one is 100% here for comedy. The Hopps family is so big. So, so big. But Nick has his own shadowy intrigue- petty criminals? Normal people who failed their son? Relatives who disdained their criminal relation until he joined the police?
Friends consummate mating cycle triggered by accident; they disagree on whether they're now married
Yeeep, it's the one where you play up their animal characteristics to the max. Differences between species, between predator and prey, just a whole lot of confusion and frustration between them before figuring out their situation.

Character Acts Like Engagement Was Accidental But Knew Exactly What They Were Doing

Ouran High School Host Club
Fujioka Haruhi/Suoh Tamaki
Specific DNW: non/dubcon
Arranged Marriage - partners randomly chosen through government lottery
Tamaki strikes me as the kind of person who'd go all in on his arranged marriage even before meeting Haruhi. So it'd be really fun to have Haruhi pushing back (affectionately) against his enthusiastic steamrolling of how he'd like their marriage to be.
All Agree To Marriage For Both Urgent Practical Reasons And Love - One Doesn’t Realize/Believe This
Future Arranged Spouses are Forbidden To Meet But Able To Study One Another's Hobbies
Joke proposal is treated seriously
Serious proposal is assumed to be a joke
Sleepy Hollow
Ichabod Crane/Abbie Mills
Specific DNW: Noncon. Dubcon is okay.
Okay, upfront, I did not finish watching this show, for what are probably obvious reasons. So you can go with canon events and write this post-canon, or you can diverge at any point or even before the start of the show, or go full AU. For Katerina, it's fine to leave her dead, or amicably divorced for an AU, or just not mention her.
Discussing New Married Name
Helping New Spouse Settle Into Their New Clan/Village/City/Country
I love Crane interacting with the modern world. I love it so much. Give me the goofiest contrasts between his first wedding and his new one, or the perceptions on how superstition and tradition has evolved. Give me all of the weird and wonderful things Abbie brings up jokingly just to see him react. Give me him catching her offguard by having asked around and figured some things out in advance.

Créme de la Créme
Delacroix/Main Character/Max
Specific DNW: non/dubcon
Look, I just want Delacroix to be happy, okay. Other than that, please feel free to do as you please. Genderwise I don't care what combination you write, but it'd be nice if Max and Delacroix aren't the same gender. For the main character, you can write them how you want, but preferably their parents backed a corrupt candidate.
About to Marry Someone Else But Dead Previous Spouse is Actually Alive
Accidentally marrying the dead
Naturally, this is Delacroix's show, but whether Max or the main character is dead is up to you. Maybe it's assumed that Max died/disappeared in Lady Renaldt's mines, or the main character was a past student instead of a new one.
A/B/O - Marriage Triad Two Alphas and One Omega
Can't Marry Until They Find Their Third A/B/O
Married couple both pine for same third person
Polyamerous Group Creates their Own Non-Traditional Wedding Ceremony
Secret marriage becoming public knowledge turns out to be for the best
Elementary
Sherlock Holmes/Joan Watson
Specific DNW: noncon. Dubcon is okay.
Joan and Sherlock self-evidently have a very strange, very close relationship, whether it's platonic or romantic. So you can take this all kinds of ways, whether it's friends to lovers, friends who are platonically married, etc. Proposal-wise, maybe, just maybe, when Sherlock got on one knee to get his mother's ring, he proposes instead?
Character Surprises Future Spouse with Their Family at the Wedding
If Joan has never met Mycroft or Morland and Sherlock held back from introducing her, this would be prime awkward comedy/feels.
Everyone Thought They Were Already Married
Marriage Mistaken For Sexual Slavery By Outsider
Secretly legally married for convenience
Some ways Joan might have been introduced while still being Sherlock's sober companion...
fake wedding to bait criminals and/or enemies
Come on, imagine Moriarty's face when she finds this out, whether or not she's in jail.
Mistaken Belief That Arranged Marriage Will Be To Sibling of Intended
Mycroft? Oren? Lin? For this one I'd prefer that there's no attraction to any of the siblings during the mistake being made.

Sybil Ramkin/Havelock Vetinari/Samuel Vimes (Discworld)
Sybil Ramkin/Samuel Vimes (Discworld)
Specific DNW: non/dubcon
Bard Immortalizes Wedding in Ballad To Couple's Delight or Embarrassment
Mal and Polly would probably enjoy it… for the first couple verses, and then Polly might get as sick of it as 'Sweet Polly Oliver'. Meanwhile, Vimes just cringes.
Character Surprises Future Spouse with Their Family at the Wedding
Vampire family? Distant Ramkins? Lady Roberta? Vimes cousins? This could go so funny or so weird, just go for all the unfortunate or delightful impressions everyone is suffering.
Long-Time Betrothed Couple Adds Third To Marriage For Political Reasons And Falls In Love
Vimes/Vetinari? Sybil/Vimes? Sybil/Vetinari? I would just be intrigued what the heck kind of political reason Ankh-Morpork could cook up. Imagine the speculation on the street!

Black Panther
Erik Killmonger/Shuri (Black Panther)
Erik Killmonger/T'Challa (Black Panther)
James "Bucky" Barnes/Shuri (Black Panther)
For Killmonger ships, I'm fine with both Killmonger Lives and King N'Jadaka AUs.
For any freeforms involving crime/enemies/assassination, if it's Bucky/Shuri, I'm totally down for Winter Soldier/Shuri.

Lonely Young Woman/Eldritch Horror That Lives In Her Basement (Original Work)
Xeno af! Would love some uncommon kinks to go with this, like vore or somnophilia.
Accepting Their Proposal to Spite Them
Accidentally Married Someone You Hate
Enemies to lovers is one of my favourite things, especially when they can't annul or divorce ASAP. Passive aggressive sniping, banding together against a third party, finding more ways to hate each other, discovering ways in which their new spouse is actually likeable...
Guardian marrying ward when they come of age
This is a chance to go all in on dub/noncon. Age difference, power differential, go for it. An older female guardian would be amazing too.
