A World Divided (GxG)

The world is divided in half, straights and non-straights. When a human or animal questions their sexuality, they get switched to the other side and all remembrance of them is forgotten and transferred into their new family and friends. They don't know who their new friends or family are, but their friends and family know who they are. The non-straight world is divided by sexuality, but only for living quarters, they're all allowed to communicate within different sexualities as they please.
Jesse, a "straight" girl discovers she might like her bisexual best friend back, and wakes up in a whole new universe, with whole new people, except a few from school, including her best friend. Her new life is rough, but once she learns why she's there and how much better life is, she discovers her true sexuality and finally gets the guts to ask her best friend to be her girlfriend.
