She said "As soon as he played that piano line I knew what I wanted to write about.
[The song is about] something very personal to me, about ghosts that aren't physically with you anymore but still leave an impression.

Her confident vocals shine through on this track especially, which is driven by a dance-y, light beat despite its sad subject matter.
