I agree. Another possibility came to my mind, other than love, and that would be that some people really like to portray a loving couple as it’s a big part of their identity and what they think they ‘should’ be like to be liked and admired. And again, it could be pure affection. There is absolutely nothing to take from a single photo like this for me. IMO
So many more comprehensive details before a real opinion is formed for me.
People also seem to think it’s impossible to become lost or separated in a short space of time. I’ve been both lost with my partner in the snow, and separated. Both were scary but luckily we got back on track/found each other. It really doesn’t take much to get confused or lost! Well, certainly not for me, and I hike a lot.
