One day, you passed by Rei in the hallway. Then, they were hit by pheromones unlike anything they had ever felt before. They were supposed to have taken their medication, but it had no effect at all. That day, they desperately walked to the nurse's office, left school early, and went home.

However, when they arrived at school the next day, an α who had witnessed the whole incident had spread the story throughout the school.

When they reached the classroom, everyone was gossiping. Then came lunch break. The back door of the nearly empty classroom opened. They could sense that pheromone presence.
