I don't know if you meant it - but the photo does deliver an ambivalent feeling to me - it is pretty romantic at first glance, what with that simple, quiet hand holding and the closeness of their bodies, but looking a little more, and being affected by the darkness of the skies that seeps into the couple as well, and looking at their expressions and the way the man looks a little aside, it looks like there is something unsolved lurking below the surface.
Not necessarily that something is wrong between them, maybe just tense - like if they experienced an hard experience lately - the lost of a dear family member or something of the kind.

am I totally off the mark? please do tell me :)
