Prompt 13: The Hidden Alpha
So I realized that the Omega verse is getting more popular and have read several stories with it. They were all different stories, but one thing was always the same: Shinichi was the Omega. Now this is my idea, where for once Shinichi would be the Alpha and Kaito the Omega:
At the age of 15, it is known that Omegas have their first heat and Alphas start to notice the subtle differences of pheromones between Betas, Omegas and other Alphas. They also feel the desire to find their mate.
When Kaito found out that he was an Omega, he was less than pleased. He always assumed to be an alpha like his father, not an Omega like his mother. Right away he started taking suppressants to not go into heat and decided to hide that fact, with his Beta-childhoodfriend Aoko's help, the only one besides his mother who knew. His life only got harder, when he found the KID room and had to constantly clash with his taskforce and Hakuba, thanks to the police only allowing Betas and Alphas to join.
When Shinichi found out that he was an Alpha, his life continued more or less like before: Still a Sherlock Holmes fanatic and a detective. But then Conan happened and everything went down the drain. His shrinking didn't put his body before he 'awakened', but it subdued his instincts as an Alpha and nearly stopped his pheromones production entirely, which fortunately allowed him not to be noticed as one. His cover as a kid would have been blown instantly otherwise.
When these two people met for the first time, they both noticed something off about the other, although neither of them could place the strange feeling as of yet.
Only now after writing it, do I notice that this seems more like a prologue… ah, whatever! Anyway, the idea is that even though Conan doesn't really give off the feeling of being an Alpha, Kaito feels his body slightly react as if he's at least in the presence of one (like fast beating heart, short of breath, wanting to get closer etc.). It confuses him, especially because he doesn't know how a heat feels thanks to always taking the suppressants. But these suppressants are really not good for an Omegas health and at some point in time, a heat will come with a vengeance that even the suppressants won't work anymore. Conan on the other hand doesn't really understand why he wants KID's attention all to himself and tries to ignore the feeling of being drawn to him (KID is believed by the masses to be an alpha), especially because he can't really do anything with his child body. The temporary antidotes are a hazard too, because whenever he turns back he gets hit by an extreme wave of wanting to mate, thanks to that feeling being subdued while shrunk.
I don't really care about the other characters role, except for Aoko and Ran both being Betas and Hakuba being an Alpha. I also don't mind smut happening in later chapters, but in the beginning there's obviously nothing the like because Conan's Alpha pheromones are barely there, thanks to being shrunk and I don't like the concept of them meeting and instantly having sex and getting pregnant a lot of these stories have.
