Two people live in two different worlds. One lives in a humble city that surrounds a tall artificial mountain. The other lives in a perfect city atop that mountain. From a young age, they have been taught that the other side was dangerous. For a young man, he was told they were synthetic monsters on top of the mountain. For a young woman, she was told dangerous beasts surrounded the mountain. When their paths cross, they will find that they both call themselves human, and they will learn to get along, even if their worlds reject them for it.
