I do not consider this photo romantic at all. Although there are many things to consider. In the background there are many other sailors and women cheering them on. So obviously this is either a parade of some sort, or the sailors are being welcomed home. Given how the woman is taken aback and how the man is holding her, I do not think they know each other. It simply seems like a spur of the moment occurrence due to adrenaline. I also do not consider this assault since that is a very harsh thing. I simply think this is an spontaneous incident, albeit I do hope it is indeed romantic.
