lol, 164kb of text file is a LOT to me :D
anyway, i've downloaded the game and seen those lines.
To be honest, >>12 it's obvious that there's two persons here,
but i'm not sure who is who.
the line start with "..." is the dialog and other lines are like, um, stage directions(not the dialog but people's actions).
My guess is the people who were 立っていた(standing) and talking here are, two people, YOU(player of the game) and the girl.

...this introduction gives me an idea of bad(unhappy) ending...;_;
