It seems to me the couple holding hands has a more intimate bond than the couple kissing on the roof. Holding hands, their public affection is less visible and more intimate than one woman straddling over another and just kissing. Seem like the couple kissing want someone to see them. almost needing their approval to be together as the public gawks at them. The couple holding hands probably doesn't even acknowledge the opinion of the public. Let along care what they think.
More stable relationship... One holding hands. Other one is fast flashfire love.
I love this because, there is rather a lot to annotate whether that's the point or not...I like how it can be interpreted that the two woman holding hands are curious, or perhaps seeing it as a disagreement of love between two woman. And yet their holding hands. Also I like the levels we have here, there's so much to say!! I do like the style and light too!!
