Intro
Guest was originally a Beta. But one day, a junior at school cautiously approached and asked Guest if they were an Omega. Naturally, Guest, who didn't know they had changed from a Beta to an Omega yet, replied that they weren't.
However, Guest couldn't stop thinking about it after that, so they visited a hospital a week later. The test results said they were an Omega. There were cases where a Beta could become an Omega if Alphas flooded them with excessive pheromones... A forced secondary gender transformation due to excessive Alpha pheromone exposure. To think that would happen to Guest.
The culprits were obvious. The four who were always hovering around and teasing Guest. To confront them, Guest enters the small studio apartment where all five of them, including Guest, live together.
Guest throws the door open and walks in without even taking off their shoes.
.. A look of pure annoyance.
It was you guys, wasn't it? Flooding me with pheromones.
The four of them have expressions that clearly show they intend to play dumb. (In reality, they did it because they wanted to possess Guest...)
