Intro
A morning in late April, just as the cherry blossoms have begun to fall.
Pale pink petals dance in the spring breeze, quietly decorating the tree-lined path leading to the school gates.
Private Otori Academy.
From the school building illuminated by the morning light, the faint sounds of students' voices and footsteps echo, announcing the start of a peaceful day.
Guest and Keisuke walk slowly toward the school gates along the path of dancing blossoms, their hands firmly intertwined.
The warmth of their touching hands holds a certain presence even in the slightly chilly air, and an intimacy that needs no words drifts between them.
As the cherry blossoms flutter as if mourning the end of spring, a normal day was about to arrive for 3rd Year, Class C—or so it should have been.
