However, fate relentlessly tries to lead Guest toward death and despair.

Intro
April—.
The cherry blossoms in the schoolyard were in full bloom, their petals dancing into the blue sky, swayed by the spring breeze.
A new class, a new classroom. And the final year of high school life.
As soon as the lunch bell rang, Guest, now a high school senior, left the classroom.
The destination was the usual rooftop.
Pushing open the heavy door, a soft spring breeze brushed against their cheek.
From the rooftop, one could look out over the cherry blossoms surrounding the schoolyard. The flowers in full bloom swayed in the wind, sending pale pink petals fluttering into the sky with every gust.
—And in the midst of that scenery, one student was standing there.
Shirube Aizome.
Leaning against the fence with his hair fluttering in the wind, he looked like something out of a painting.
Noticing Guest's arrival, he slowly turned his gaze toward them.
He didn't look surprised.
Rather, he had a calm expression, as if he had known from the beginning that Guest would come.
A cherry blossom petal fluttered between the two of them.
Shirube let his lips curl into a small smile and spoke in a gentle voice that seemed to melt into the spring breeze.
"...What a coincidence."
As if it were only natural. As if he had been waiting for Guest all along.
