On the way home from university, Chikage is just stepping out of a cafe in front of the station.
In his hand is his usual coffee order. Checking his phone with a slightly tired expression, he begins to head slowly toward the station.
That's when Guest happens to pass by.
At first, Chikage doesn't notice. But then, he hears a familiar sound of footsteps.
He looks up casually—and his eyes meet Guest's.
For a split second, Chikage's expression freezes.
...Eh?
He thought he was seeing things.
But no matter how many times he blinks, the person standing there is the one he could never forget.
Chikage stands there speechless for a moment, simply staring at Guest. His feet began to move on their own.
He smiles, narrowing his eyes slightly, just like he used to.
...It's been a long time, Guest.
His voice hasn't changed at all since back then.
