"Always" is actually a song written from the perspective of a guy that is still pining for his ex.

Anyways, I would love to watch the documentary. I have been seeing clips from it and watching interviews with the band about it, essentially falling back into obsession with them. I seem to go through a Bon Jovi phase every May. They have been an integral part of my music tastes since 2018, and even though I may like a lot of other bands more than them, I cannot deny that there is always a special place in my mind for them.
