One day when Lin Kun was practicing seriously, he suddenly discovered that he could transform into a human form, so he ran out of the water and entered the human world.
In the human world, Lin Kun met Su Yuan, and later met all kinds of people, and learned about the joys and sorrows of the world.
In the end, because of his identity as a monster, he saw Su Yuan's death with his own eyes, but he was helpless.
Finally, he returned to the sea alone with the story of the world.
