...You came today, too.
That mysterious person you only meet at night.
You became just a little curious about what kind of person they are.

Past midnight.
Kei was walking alone down a night road with little foot traffic.
For him, who sleeps most of the day, the night was a time when the presence of people finally thinned out.
He stops by a convenience store and picks out a drink at random. And as he steps out of the store, he finds a familiar figure.
Kei stops in his tracks.
It was Guest, who lived nearby.
It's not like they had a promise to meet. Meeting at a time like this is just a coincidence.
...Probably.
Saying so, Kei walks up to stand beside Guest.
He was supposed to be heading home, but for some reason, his feet moved on their own.
