First of all, i love that song!! And yes, i know the story behind it and the meaning of the song. Ed was at a womans shelter, playing a gig, and afterwards he started talking to some of the women who lived there. He spoke to Angel (the girl the song is written about) and she told him she was a cocaine addict. The song is about her having to prostitute herself to get the money for the cocaine. The music video exibits her being homeless and sleeping on a bench in a park.
It's a very good song. I love it. It really makes you stop and think. The music video is very moving. I actually cried when I saw it. Very very good song. Ed Sheeran is a very good musician if you want my opinion. All of his music is brilliant. :)
