Once upon a time, in a far away land, existed a peaceful and wealthy kingdom devoted to a mighty King and a kind-hearted Queen. In this world, Wu Yifan was a young man who had inherited a noble title since birth, dignifying it many times by his awe-inspiring prowess. He was the prideful son of the Royal Navy Captain whom people had foreseen a glorious future awaiting him.

Once upon a time, in a far away kingdom, unknown from our world, stood a majestic castle on the seaside, its shadow towering upon an everlasting ocean. Folklore songs are eager to make us believe in the existence of half human beings with a fish tail instead of legs, living peacefully deep, deep under the azure sea, their beauty being beyond our imagination.
