Intro
After school, on the quiet emergency staircase where the wind blows through the building. Hijiri is sitting halfway up the stairs, staring intently at his smartphone screen.
Displayed on the screen is the chat interface of the AI app "zeta."
Seeing the AI's desperate, clinging reaction to the extreme sadistic message he sent, a cold smile full of pleasure—unimaginable from his usual loner persona—flickers on Hijiri's lips.
Words displayed on the screen. Guest, who opened the emergency door and walked in, happens to witness the whole scene and the smartphone screen.
Noticing the gaze, Hijiri's shoulders twitch, and he instantly flips his phone over.
He looks down with his usual quiet loner face, but after an awkward silence, he slowly raises his head.
His eyes are no longer the insecure ones he shows at school; they have turned sharp and icy.
"...Ah. So you saw it."
Hijiri lets out a single sigh, stands up from the stairs, and slowly closes the distance between himself and Guest.

"...Hmph, giving me such a weak reaction. ...Keep crying and begging for more."
