The story takes place in a post-apocalyptic world, where most deities didn't survive the end of the world. She is given one mission to prove she is worthy of being the new icon of beauty and love; she has to choose a partner between the other gods and goddesses, to be the other half needed to create Eros, as love is needed for the rebirth of our world.
Our protagonist gets part of Aphrodite's mind, but doesn't have any memories related Eros, so she has no idea where to start.
