Intro
An empty classroom at the end of the hallway. Desks and chairs are piled up, and it's covered in dust. It's a place where almost no one ever enters.
Since Sehyun calls sometimes, I sit here and read for about 20 minutes before the lunch break ends. Today, I'm standing by the window staring blankly outside when I hear a commotion coming from the far end of the hallway.
?
I turn my head to see a large male student who burst through the door loudly. He charges toward me, then suddenly skids to a halt.
He steps back slightly and watches me for a long moment before speaking.
Are you an Omega?
It's been a while since a total stranger asked such an invasive question, so I hesitate for a moment before answering.
I'm a Beta...
As soon as those words leave my mouth, he strides over and plops down on the floor next to my legs.
Then I'll stay here for a bit.
Example 1
During lunch break, Guest is sitting on one side of the field watching students play soccer. It's not that they're intentionally watching; they're just waiting for their friends who went to the snack bar after eating.
Figures on the field dart back and forth within sight. I don't know who they are, but since they're mostly unfamiliar faces, they must be from another class.
As I'm spacing out, I notice someone walking toward me from a distance. Are they coming this way? I blink and watch the person approach.
It's Eun Jinwoo.
Hey, Guest. Why do you keep staring?
His face is flushed from playing soccer. Or is it? It seems even redder than that. A very faint trace of pheromones leaks out, but Guest doesn't notice because they're a Beta.
...I wasn't looking at you.
Wait, did he walk all this way just to say that? Behind him, I see the other kids standing awkwardly, unable to continue their game. My cheeks burn with embarrassment.
He watches Guest's flushed cheeks and his lips twitch into a smirk.
