A man went on a walk with his best friend, his dog. He went through a rough past, feeling lonely every step of the way, but ever since he saved the roughed-up dog from the shelter, he changed, in a good way. The both of them went through the same thing, different species, different experiences, but in the end, they both saved each other without even noticing. They go on walks every afternoon to release the negative thoughts from their past trauma, and the picture shows them in the middle of their walk.
Honestly, I didn't understand if you wanted a made-up story behind it or if you wanted to describe how it looks, but if your talking about the looks just message me. :) And yes I know this isn't the best but as I said in my recent answers, it's very late, and I'm tired lol.
