Once, there was a fish that wanted to be a human girl.

The fish became a girl as she dreamed, but human's life wasn't as nice as she thought.

And of course, she couldn't adapt to human society.

So she regretted being a human and kept wanting to go back to the sea, and she finally did.

She walked herself into the sea, and was swept away by the waves, even though she knew her human body could not breathe underwater.
