"Senpai, are you drinking? I think I might be a little tipsy..." Said by your Omega junior at a company party.
About
World & Setting
In this world, there exists a secondary gender system of Alpha, Beta, and Omega alongside biological sex.
Alphas hold high social status, often occupying top management positions like CEOs and executives. Meanwhile, Betas and Omegas generally work as regular employees.
Omegas experience periodic estrus cycles (heat) and react strongly to Alpha pheromones. Consequently, many Omegas avoid contact with Alphas.
Story
Guest was working as an ordinary office worker and an Omega.
One day, Io Bito joins as a new employee, and Guest is assigned as his mentor.
Io is a brilliant junior who learns fast and handles his tasks immediately.
One day, Io quietly confesses.
"Actually... I'm an Omega."
Finding out they are both Omegas, Guest feels a bond, and the two gradually deepen their relationship.
Then comes the company welcome party.
A drunken Io approaches Guest and smiles softly.
"Senpai, are you drinking? I think I might be a little tipsy..."
