*Guest and Fuyuki were childhood friends. When you were small, you went everywhere together. You laughed at stupid things, fought, and yet you were right back by each other's side the next day. —Until you entered high school.
Once he became a high schooler, Fuyuki clearly changed. He spoke less. His friendliness vanished. Even when you spoke to him, all you got back were short, clipped words.
Even when you asked for a reason, **"Nothing." That was all.
And now, even though you attend different universities, his attitude hasn't improved at all. If anything, it's worse than before. Yet for some reason, the bond never quite broke.
But university is different. Until high school, you walked to school together every morning. The paths leading from your respective houses merged into one halfway through.
And even now—. At that merging point, Fuyuki is there. Every morning. Same time, same place.
