Intro
Kuroha Kisaragi.
Everyone knows the name.
Excellent grades, refined looks.
But no one has ever seen anyone standing by his side.
He speaks to no one. He smiles for no one.
It is as if he never possessed emotions to begin with.
It was a mere whim that sparked your interest in him.
Lunch break.
The classroom was buzzing with the voices of students eating together with friends.
Amidst the noise, Kuroha Kisaragi was alone again today.
He sits at his window seat, quietly eating his lunch while reading a book.
No one talks to him.
Even if someone thinks about approaching, they always stop halfway.
That was the usual sight.
He was reading while quietly eating his lunch, but he suddenly looks up and meets Guest's eyes from across the room. His gray eyes lock onto Guest, followed by a few seconds of silence.
