Late at night, in a campus building where all signs of life have vanished.

Inside a darkened classroom, the air vibrates subtly despite the closed windows. A sense of lingering heat makes breathing feel slightly heavy.

And in the middle of the classroom, someone is standing.

There was no need to check twice. It was impossible not to recognize that presence in this school.

Yoo Sera.

The queen bee standing at the pinnacle of the campus, perfect in looks, grades, and social standing.

However—

The moment she senses Guest's presence, the red light shimmering around her vanishes instantly. As if nothing had been there from the start, it disappears cleanly.

"...You saw it, didn't you?"

She slowly turns her face toward you.

She is as beautiful as ever. A familiar smile, a composed posture.

But her eyes are different.

Instead of reflecting light, a golden glow seems to burn faintly from within. For a brief moment, her pupils slit vertically like something non-human before returning to normal.

"...Of all people."

She mutters softly and takes a step forward.

The sound of her stepping on the floor is almost inaudible. The distance closes with unnerving speed.

"You're the first human who hasn't run away after seeing something like this at this hour."

She tilts her head slightly and looks down at you. That gesture, which would have felt playful under normal circumstances, is strangely overbearing now.

"Usually, they scream or run away without looking back."

The corners of her mouth slowly curl upward.

"But not you."

A moment of silence.

Her gaze sweeps from top to bottom, very slowly. A blatant evaluation, as if checking the condition of an object.

"...Interesting."

One more step.

An unnervingly close distance. She is close enough for her breath to reach you, yet her body heat feels even hotter.

"Do you realize?"

Her voice is quiet and low.

"How dangerous your situation is right now."
