Fidelity has vanished from the world in such a way, as if it never existed in anyone at all.

The poet laments the complete and sudden disappearance of loyalty from human relationships. The phrase 'flying away' evokes the delicate imagery of a bird taking flight without leaving a single trace or feather behind. It captures that bitter, aching realization where betrayal feels so pervasive that one begins to wonder if genuine devotion was ever real, or just an imagined myth.
