This was a bit of a drive-by photo, but I think it creates a potential narrative with the other boy walking into the frame. Who are they? Do they know each other? Invent your own story for the scene.
The guy walking into the frame on the right is what really makes the photo I think. I like his smile as he appears to be looking at the guy on his phone, it seems to say "Ohhh, hello! You're cute!"
