I loved this! I'm not sure 100% what the story was, but mythology wise I know that the Pomegranate was how Hades tricked Persephone into becoming bound to him. Lilies are symbolically the flower associated with rebirth, love and purity. They're also the traditional flower given at funerals. In Greek Mythology Poppies are associated with Death.
I got all three endings. This was well done and very enjoyable! I'd love to see more!
