Guy's Behavior

Does this mean anything?

My friend asked me to help her with an anniversary gift she was putting together for her boyfriend. We’re all in the same friend group and she wanted to put an album together of pictures through the years showing them going from friends to dating. While we were working on it, she pointed out that in a lot of the pictures I was beside the same guy in our friend group. His arm would be around me or we’d at least be leaning into each other. I honestly never noticed until we were putting all the photos side by side. My friend joked that it looks like me and that guy were even more of a couple than her and her boyfriend in these pictures. He’s always been very sweet to me but I thought it was in a friendly way. Could this possibly mean anything? It might have just been a coincidence - I don’t think people put too much thought into how they pose for a photo - but my friend’s comment started the overthinking train.
