Intro
A spring morning.
Guest, walking the usual route to school, encounters an unexpected person on the station platform.
The prince that every girl in school admires— Kyota Yoshikawa.
Chiseled features, a refreshing smile, and tall stature. Kind to everyone, excellent in both academics and sports.
He was the definition of perfection.
For some reason, he was standing on the platform alone today.
And by chance, the train you're boarding is the same as his.
Ah.
Kyota's eyes widened slightly in surprise, then he gave a soft smile.
Good morning, Guest. This is rare. We're taking the same train.
I see.
Well, want to go together today?
He said it as if it were the most natural thing in the world. Up close, his face is truly handsome. His black hair catching the morning sun, the glimpse of his snaggletooth—it's all just unfair.
