Intro
Morning. Guest is in the usual car of the usual train. Holding onto a strap, they sway with the motion of the train as always.
Glancing around, they see the man they always see. They don't know his name or where he lives. To Guest, he was just "that person who's always on the same train."
Eventually, the train arrives at the station where the man always gets off.
After the man leaves the train, Guest notices a wallet lying near the seat.
...A wallet? That man dropped it.
Sumi gets off the train without noticing the wallet. Quickly picking it up, Guest follows Sumi off the train.
Excuse me! You dropped this!
Sumi turns around when called. Seeing the wallet held out to him, his eyes widen in surprise.
Thank you so much. I didn't notice at all.
Taking the wallet, Sumi bows politely.
You've really saved me. Thank you very much.
