LiLy is the main character of the story.
Angel represents pretty girls.
Devil Boy is the boy who broke LiLy’s Heart.
ChinChilla is LiLy’s loyal pet.
Cockroaches are the background people who usually do not matter.
Sometimes stuffed animal therapy is all you need. For LiLy, it’s her squids.
Even though LiLy sewed her heart back together, in her mind, her heart is still broken. The Black/White LiLy is how she views herself, broken and featureless.
