In the story of Cupid and Psyche, Cupid represents love while Psyche represents the soul.
The moral of this story is "curiosity kills the cat". As you may or may not know, Psyche was instructed by Cupid (while he was invisible) to not try and find his identity, or what he looked like.
However, Psyche was so curious and did what she was told not to do, because of her curiosity. This caused Cupid to be heartbroken and their relationship was dented.
