Hello can I offer you an omegaverse arranged marriage Techno/Ranboo AU in these trying times?
Ranboo is the prince of a kingdom, heir to the throne. He is also an alpha. The rules of this country are that a royal cannot claim the crown before they have a mate, which in noble circles usually happens from the age of 20 upward, with most being mated by the age of 25 or so. They're often arranged marriages, with the omega getting little say in the matter.
Ranboo's parents died when he was younger. He has a capable regent who has been leading the country with his input, but as he turns 20 he is eager to get a mate so he can get the throne.
As is custom, a bunch of nobleborn omegas who are unmated are brought to parade in front of Ranboo, each hoping to win his favor and be the future queen of the country. Ranboo tells himself that he has little interest in who his mate is (normally his parents would pick for him anyway, Ranboo hates the decision anxiety), as he's more concerned with the whole coronation thing.
Until his eyes fall on an omega who stands out a little from the rest.
The omega in question is probably the oldest there at 24 years of age. He is tall for an omega (though still several inches shorter than Ranboo), more muscled than omegas usually are (though it doesn't completely hide the more curved, soft edges of the typical omega physique). He has scars, and long pink hair in a half-updo with braids, and he is wearing a long, red dress with details of lace, a bodice that hugs his chest a little too tight, and a high slit in the side that reveals maybe a bit too much of those powerful thighs that could crush Ranboo's head like a grape.
Ranboo might be an alpha but this poor guy is whipped.
So he has an instant interest, that only heightens as he interacts with the omega and gets to experience that dry wit, the clever mind, the spirited nature. He has non-traditional hobbies for an omega: horseback riding, archery, sword fighting. This is an omega unlike any Ranboo has ever met. One that isn't looking to bow down to an alpha ruler.
Obviously, not all omegas are completely submissive, but in the noble cirlces most omegas are raised on more traditional values. So this one is an outlier.
His name is Techno from house Blade.
Ranboo's advisors try to disuade him from the match. They say there are some nasty rumors about Techno. Common belief is that Techno was mated at age 18 like most omegas are, to a young alpha from a noble family. The alpha in question was a not good person though, and a not good mate. He was abusive, and evil, and wanted his omega to be a sex slave but nothing more.
Rumor has it that Techno snapped and killed the alpha when he couldn't stand it anymore.
(Rumor would be correct.)
The matter was more or less swept under the rug, but no other alpha would consider giving Techno a second look. A lot of them were scared to end the same as Techno's original mate. Others didn't bother with an omega who wasn't a virgin anymore, who had been bitten and marked and soiled by another alpha once. Others were disgusted and turned off by the idea of a mate who was so independant and not submissive. And maybe a very few actually were traditional enough to believe that omegas really should be just sex slaves, so they weren't keen on Techno either.
But Ranboo has decided. This is the omega he wants. He's sold. Head over heels, "mommy? sorry.... mommy?" vibes.
The marriage is arranged (and slightly against Techno's will initially) though Ranboo knows that he wants to do right by Techno and win his trust, slowly peeling back layer by layer, and showing Techno how nice it can be to have a good mate.
And hey, maybe eventually Techno even trusts him enough to show his softer, submissive side. Because trust me Techno definitely has one ;)
