This is a nice story and I changed it to read more naturally in English. I hope you approve.
Lovers on the Underground
After shooting a photo session for the magazine, I wanted to go to home and rest but had to take the underground because my car was broken down. While waiting, I saw two lovers in the station. They were standing very close to each other, talking, and appeared to be very much in love. I secretly took a photo of them. I never saw them again but the photo became very popular in my country.
A few years later, I had an exhibition of my photos. While talking with some friends, a man came up to me and said he knew the couple, that they lived in a town nearby, and he would introduce me if I wished. Immediately I decided to go meet them. When we arrived, I was introduced to the couple. Upon seeing the photo, they told me it was their first date and they are still together! I was happy to be a part of this story!
