The desert could be a macaron, an éclair, crème brûlée, mousse au chocolat, and crêpes.
Marin and Marinette are adopted by an old woman who lives alone with her only daughter on a remote island. When Marin grows older, he leaves the island to find a better life for himself and his sister. When good fortune comes to the twins, the old woman and her daughter grow jealous and plot against them.
Marin is the main character and twin brother to Marinette. When he works for the king, he is very dedicated and diligent. He is kind because after the king discovers Marinette's picture and falls in love, he retrieves his sister from the island they had both lived on. The old woman and her daughter insist that they must join him, because they had raised them. Even though he is suspicious of the woman's intentions, Marin is grateful to them for taking care of them, so he agrees and keeps his word.
Marinette is Marin's innocent, beautiful sister. She cares about Marin, so when he suggests him leaving to the kingdom, she supports him. And in the end, after she is freed, Marin asks her to stay on the island with him forever, where they will be safe with each other. Marienette agrees, but she says she wishes to show the king the truth, and prove that Marin did not deceive him, because she knew her brother had done no wrong.
The king is welcoming and kind to Marin. He accepts him and trusts Marin immediately. When he learned of Marin's betrayal, he did not believe it at first. To his subjects, he is loyal and loving, putting their needs first. When his kingdom needed a queen, he married Marotte, despite his apathy for the girl.
The old man mostly keeps to himself, but is kind enough to teach Marin how to keep a garden, and this allows Marin to find a job at the king's castle. When he learns of Marin's predicament, without hesitation, he offers to help him, and starts to assemble the tools needed to free Marinette from the Sea Fairy, and assists in the breaking of the chain.
The Sea Fairy watches over Marin and Marinette throughout the story, first saving them from the ship wreck as children, and then saving Marinette from drowning on the way to the king. In return, she keeps Marinette in her castle.
The old woman gets jealous of Marinette's good fortune in catching the eye of the king. When Marin arrives to take Marinette to the king, the old woman insists upon joining them to the kingdom. On their way, a violent storm hits their boat, and the woman seizes this oppurtunity tothrow Marinette overboard. Marin is unable to save Marinette, and because of this, is so overcome with grief that he becomes mute. Upon arrival to the kingdom, the old woman claims that her daughter, Marotte, is Marinette so that the king will marry her. To insure that Marin does not tell the king the truth, the woman kills the king's prized bird and son, in attempt to turn the king on Marin.
Marotte conspires with her mother against Marinette and Marin. She lies to the king about her identity in order to become the queen.
