Sighting

I am writing to you in English here, as I don’t know if you speak German.
We saw each other a year ago—on October 1, 2025, around 8:50 AM—on the U1 subway line in Vienna, heading from the Main Station towards Stephansplatz; we were at the rear end of the train.
At some point, our eyes met; you touched me so deeply with your enchanting eyes and smile that, even now—a year later—I still cannot forget you.
If you are reading this and remember the moment, please give me a sign so I know whether or not I can keep hoping to meet you someday.
Thank you!
