DevilsRegret : it's about an angel by heart , that's pushed to a dark hole where she doesn't belong , nobody's there by her side to help her figure out the way through. She's trying to help the other falling angels the way out by heart , but they all go away without her, the atmosphere is so heavily dark that she's getting affected with anger, sadness, and close enough to end it.

This is a metaphor about part of my life . Good luck.
