Story
A Happy Mermaid Princess
The Mermaid Princess is the titular protagonist of a famous storybook. In the story, she has been granted permission by the Queen to swim up to the surface of the sea to see the upper world, sees a prince on a large ship, and falls in love with him from a safe distance. A violent storm hits, causing the ship to ship, and she saves the prince from drowning. She delivers him unconscious to shore, waiting until a princess from another country and her servants find him.
In the original story, she was given a potion from a witch to turn her tail into a pair of legs in exchange for her voice so she could see the prince once more. However, the prince is engaged to marry the princess. The Mermaid Princess has to kill the prince to save her life because the spell entailed she would die the next morning if the prince married someone else unless she kills him, but she cannot bring herself to do so. In the end, she took her own life by throwing herself into the water and dissolving into foam.
To make a little girl happy, Doraemon enters the story and intervenes when the mermaid is about to trade away her voice for the potion. Doraemon helps her receive the potion by exchanging for her starfish headpin, despite the sea witch's objections. The mermaid, while getting to know Doraemon, meets the prince and they have fun playing in the woods. However, this does not change the ending as she still ends her life dissolving into foam. Doraemon reenters the story and finds out the neighboring princess is still going to marry the prince. He is unable to convince that it was actually the mermaid princess who saved him, and she leaves the castle in tears. Having developed feelings for Doraemon throughout the story because of his good deeds, she proposes to him, but Doraemon comes to his senses and reveals he was just trying to make her and the prince be together. Devastated by Doraemon's rejection, the princess jumps into the sea. Doraemon tries to pull her back until he gets an inspiration, releases her and flies out while the princess meets her demise.
Doraemon changes the story once more by going back to the beginning and ensuring the prince doesn't know who found him, and help the princess gain her legs and later plants a microphone to tell prince the truth. The prince asks her to marry him and she accepts. They get married in the end.
