The mermaid fell in love with the Prince, but she was not human. She had to turn into a human in order to be with the Prince, so she decided to turn her fishtail into legs.
The mermaid went to find a deep sea Witch to help her, and the witch asked her to use her beautiful voice in exchange. Although she was reluctant, The Little Mermaid agreed.
After she woke up, she had turned into a human, and her beautiful fishtail had turned into a pair of legs. The mermaid was lying helplessly on the big ship where the Prince and Princess were having their wedding.
When she saw the Prince, The Little Mermaid wanted to tell him that she was the one who had saved him, not the princess.
However, the mermaid had no voice and could not speak. She had become mute.
The Prince pitied her and took her in.
The Little Mermaid would dance for the Prince every day. Although her feet hurt like she was stepping on knives, she was willing to dance for her beloved Prince.
One night.
