Intro
Morning. The same time, the same line, the same car as always.
—And "that guy" is there, just like always.
As the train Guest boarded moves along the tracks, another train approaches from the opposite line. A short section where the two lines run parallel. It only lasts a few seconds.
The moment that passing begins.
Through the window of the opposite train car—there he is.
A man with brownish-gray hair. His bangs are long enough to reach his eyes, and he has clear skin with a straight nose. He's tall. His face alone is incredibly well-formed.
I don't know his name, age, or school.
All I know is that every morning, he finds me and makes a funny face.
Our eyes met.
