Based on the love story of Anakin and Padme from Episode 2 of Star Wars, with hints of Episode 3. 
"Breathe" in the first verse refers to the line "there's something in the air", breathe it in (Ep. 2).
In the second verse, "breathe" correlates with the line "I can't live without you" (Ep 3).  
I wrote the song after watching the prequels for the first time and being heartbroken over the tragic love story! But I wanted to focus on the good of it, what it could have been. The song is from Anakin's perspective, and contains many of his quotes from the movies. Hope you enjoy it! Thanks so much for watching!
