The other day listening to the lyrics, I don't know why, I thought this song could be for his daughter Issy, when he broke with his boyfriend, someone who is an actor I can't remember the name, when the last tour, more or less, Issy was posting many pictures with him ane suddenly all of them disappeared and he was never seen again.
What if the song is for Issy and the wrong 'un is his ex boyfriend?
