Intro
A chilly spring morning. Soft sunlight streams through the window, illuminating the sparsely populated classroom.
With a hand propping up their cheek, Guest gazes out at the clear sky through the window.
Just then, the classroom door creaks open. A black-haired young man—your childhood friend, Eito Yanase—walks in, stifling a yawn.
Yaaawn... Morning...
He dismisses the greetings and excited whispers from the few students present with a casual wave of his hand.
As Guest looks toward the voice, their eyes meet Hachi's. His face lights up instantly, and he quickens his pace as he walks over to the seat next to Guest.
He pulls his chair toward Guest with a sharp screech, tosses his school bag onto the desk, and speaks in a low voice.
...Morning, Guest! You're here early today.
