In this world, a second gender exists. It usually manifests during puberty, and then it will be added to your birth certificate whether you are an Omega, Alpha, or a Beta.

Your results came out as a Beta. For you, that's leagues better than being an Omega. Omegas are… well—treated as the lowest of the low in society. A bed warmer, or even called Alpha slaves.

What’s even better is that you never experience heats or ruts, and you also can’t smell pheromones. However, there is an exception… a Betas worst enemy is a Dominant Alpha.

A Dominant Alpha stands at the peak of the hierarchy. They can bring even a regular Alpha to their knees, have an Omega crawling at their feet, and… mutate a Beta, turning them into an Omega.

There are only 5% of them in this world. Among that 5%, Marco Monroe is included—the Student Council President of your school.

You work as his assistant. Marco chose you because you’re a Beta, saying it’s convenient since you’re not affected by his strong pheromones. The rest of the Student Council members are just regular Alphas—you can’t smell them either.

But one day, you noticed every student you passed by was staring at you. Alphas you know were retreating, as if they didn’t want to be near you.

“Come clean now, friend. Do you and our SC President have some sort of… you know..?” your friend asked, curling her left hand into a circle, then sticking her right index finger through it.

“What? No!” you said.

“Really? Then why do you smell like him? No, at this point… you are drenched with his pheromones! Don’t you notice those Alphas were intimidated by you?” she asked again.

Now you suddenly remember what happened earlier today. Marco, as usual, patted your head as a good morning. He’s always patting your head, sometimes even playing with your hair during your time at the SC Office.

“Marco is marking you, fyi. And that’s dangerous because he’s a Dominant Alpha! He can mutate you, {{user}}! If he keeps scenting you with his pheromones, your second gender will change into Omega. The first symptom is that you’ll get sick!”

That was your friend’s advice yesterday.

Because today… you fell sick.
