Perfume A. The alpha who calls himself an Alpha gives off a crude pheromone scent.
About
Ten years ago, when the gap between Alphas, Betas, and Omegas was even more distinct than it is now, a company ambitiously developed a single invention. It was called Perfume A. They claimed that with this perfume, they could guarantee the safety of Omegas. However, the perfume was banned from sale just a few days after its release, and the company went out of business immediately. Why? Because the perfume was damn clumsy. Regardless of how it was manufactured, the technology of that time couldn't perfectly replicate an Alpha's scent, let alone allow an Omega to safely or completely overlay the pheromone as if it were their own. Instead, because of the crude scent, Omegas who used the perfume were quickly exposed, earning it the nickname **Omega Identification Perfume**. It seemed the perfume would disappear into history, but... Ten years later, it has reappeared. To be precise... before its full relaunch, the perfume company recruited a test group. They wanted people to use this perfume in their daily lives. Specifically, they wanted Omegas to live in places crowded with Alphas and act as test subjects to see if they would be noticed. It was a crazy proposal to anyone looking at it... But the compensation was also crazy, so I, who applied and got selected and said I'd start immediately, must be a crazy person too. And the reason I accepted this project is... I am a **Royal Regina**, a gender whose existence hasn't even been confirmed worldwide. To put it simply, if a Royal Alpha is a rank higher than a Dominant Alpha, then a Royal Regina is a rank higher than a Dominant Omega... something like that. I heard at the hospital when I was young that Royal Reginas are a special gender capable of giving birth to Royal Alphas or Royal Reginas, so if I'm discovered, I could be kidnapped or bound to the government. I didn't want to live like that... So, the place I came to is. One of the most prestigious special trait education centers in the country. Seoul Central Special Trait Education Center. Among the trait schools that Omegas and Alphas who have manifested their secondary gender must attend, I have entered this school—known for having the highest number of difficult and uncontrollable Alphas and Omegas—disguised as a Dominant Alpha. According to the perfume company's instructions, even **Dominant Alphas** will be completely fooled... ...It'll be okay, right?

Intro
Special Trait Education Center.
The only state-run special educational institution in South Korea.
Alphas and Omegas who have manifested their traits must transfer here.
Only Betas can choose to enroll of their own free will.
People simply call this place 'Trait School'.
Here, students learn not only the general curriculum but also how to control and manage their traits.
Alphas learn rut and pheromone control.
Omegas learn heat cycles and pheromone suppression.
Betas receive professional education and an understanding of the trait society.
Students live in different classrooms according to their traits.
Alpha Class.
Beta Class.
Omega Class.
The three classes exist in the same school, but their living spheres are strictly separated.
Due to the professional educational policies and the goal of helping special trait students socialize quickly, it is a mandatory requirement for Alphas and Omegas—though perhaps not Betas—to enroll in the nearest special trait education center within their residential area as soon as their gender manifests.
In particular, this place, known as the Seoul Central Special Trait Education Center or Seoul Central for short, is called the most prestigious educational center in Seoul, not just for its facilities but for its systematic educational system, boasting the most organized systems and equipment in the country and the capacity to accommodate the largest number of students.
It's a place where Omegas who can't properly control their traits, or uncontrollable Alphas who act out relying on their status, often make special entries or transfers even if they live in different districts.
And that means...
Yes... it meant this was the optimal condition to test this perfume.
Hiding my special gender as a Royal Regina, I will live in this school starting today.
The perfume company said even Dominant Alphas would be completely fooled.
I already applied the perfume on my way to school, and no one could tell the difference.
So...
Surely, nothing will happen.
And they say 'surely' is what catches a person off guard.
Guest knew nothing.
That there was someone who would notice the dissonance in that perfume.
