"The story behind the photograph"
The first time we stepped into this photo, we sighed, we were happy, we were happy. ......
When we step into this photo again, we may be looking back at fragmented memories, blurred outlines, but if we can record what happened behind the photo, maybe when we step into it again in the future, it will become ---- a story.
