According to an interview with Billboard, Sheeran noted that this song came from spending time assisting at a homeless shelter. After hearing all the stories of the homeless there, he wrote these lyrics (amongst others).
In the interview, he stated that saying the woman was in "the class A team" was a subtle way of referring to her addiction to a class A drug; this subtlety was intentional, as Sheeran wanted the overall tone of the song to sound somewhat cheery to hide the serious nature of the lyrics' meaning.
