This is a love story about living together with your niece.

The couple's story starts in a normal, mundane town that you could find anywhere.
They spend their days together and eventually become attracted to each other.
But each of them has a wound from the past that keeps them from getting closer to each other.
Though their bodies mingle, their hearts do not.

This is a story about the relationship between an uncle and his niece, each carrying a wound that will never heal.
