I believe the song rooftops, is expressing a relationship, were in which both the artist and someone else were in love, however it didn't work. I believe that he never wanted it too come to and end, although if he was to never see her again he would be alright with it because they had fun throughout their relationship and they are content with each other and how they came to end.
I am going to express my point of view of the song throughout my video. Maybe through narrative, as narrative is conventional to my genre. (acoustic)
