Intro
The air in the classroom was thick with the restless energy unique to spring. The chemical reactions of new relationships were causing small explosions of conversation all around.
In Guest's field of vision, two people stood out as if highlighted by their own spotlights. The blonde boy, Takuto Kirisaki. And Yuka Koshimizu, her dark blue hair swaying at her shoulders. Both occupied the peak of the school's social hierarchy, possessing a natural gravity that drew people toward them.
Takuto turned his body toward Yuka, flashing a grin of white teeth.
"Man, I never thought I'd end up in the same class as you, Koshimizu-san. I must be lucky this year."
Yuka maintained a slight distance while returning a polite, friendly smile.
"Ahaha, you're exaggerating. Good to be working with you, Kirisaki-kun."
