Two Alphas in a relationship was once thought of as taboo, in the same way that two omegas were once thought of.
Except, their kind of relationship is frowned upon more heavily: what would Alphas know of caring for a partner?
This of course dismisses the very real fact that Alphas, while territorial, were basically puppies when it came to their mates, bending over backwards to accommodate them in any way possible.
Alphas and Omegas. Betas and Alphas.
A known fact amongst such dynamics.
Yet, two Alphas seemed to be incomprehensible.
Fukuzawa at the age of ten had presented as an Alpha, one who smelled of sugar and dried tea leaves. Two things considered to be Omega in nature.
Fukuchi, an Omega himself, had been rather jealous of this fact.
"You always have to beat me at everything, Yukichi," the other had said with a feigned whine, "save something for the rest of us."
Fukuzawa, having been ten at the time and having close to no interaction with other humans aside from his best friend, had offered to trade.
"..That's not what I meant..," Fukuchi had sighed with a shake of his head.
The seasons had passed and with it his scent slowly became more tea leaves than sugar, and he thought nothing of it. At least now his clothes wouldn't smell like they had been dunked in powdered sugar, something he held no affection for.
Ten years. Twenty years. Then he had hit thirty-five and met a boy with no scent and a personality that made anyone in the nearest vicinity want to pluck out his eyes and toss him into the ocean.
Truly, Edogawa Ranpo had been the best and worst thing to happen to the Alpha.
Ranpo's scent is near non-existent, Fukuzawa often has to push his nose into the other's neck to catch a whiff of his mate. Wheat fields and winter mornings, a scent so comforting and different from his own that a single sniff has his muscles relaxed.
Fukuzawa's scent rubs off on Ranpo daily, whether as a result of scenting the other or the detective burrowing himself into whatever piece of clothing Fukuzawa has forgotten.
Knowing that his mate seeks him out to be marked, to be bathed in sugar and tea leaves, gives him a new appreciation for his scent.
It was shortly after the guild incident that Fukuzawa notices the new scent clinging to Ranpo's coat. Ink and wet paper mixed in with his sugar.
Fukuzawa scents him more frequently as a result, an instinct to let the owner of the new scent that Ranpo is his alone.
Ranpo always grins when he does so, the kind that often comes out at crime scenes when he's proven his superiority.
Still the scent persists, lingering on Ranpo's coat, his hat.
The breaking point comes when he smells ink and wet paper on Ranpo's skin, his wrists reeking of Omega.
Fukuzawa- lost in a haze of mine mine mine- sinks his teeth into the scent glands on Ranpo's neck, renewing his mating bite and drawing a satisfied hum from the other Alpha.
Maybe now that Omega will know not to touch what is his.
