Please, Miss Dragon [Western Fantasy]

Legend has it that there is an evil dragon that has existed for thousands of years on the mainland. She is cruel, violent, and moody. She stays on top of the treasure all the year round. Wherever she looks with her vertical pupils, she sees scorched earth burned by dragon flames. The years are long and the dragon is boring. She finally decided to keep a pet to pass the time just like humans keep cats. For pets, she only has four requirements: noble blood, beauty and docility, the ability to learn magic, and being human. The messenger brought the news to the palace. Late one night not long after, the unloved little princess Desia took a carriage and left the palace that was like a golden cage. That year, she was only thirteen years old. * Desia's mother is a purple-haired witch. She has the ability to prophesy and is considered unlucky. Therefore, Desia, who has half the blood of a witch and also has purple hair, did not have an easy life in the palace. They were afraid of her and disgusted with her, so much that they wanted to send her to death. I heard that the environment there is harsh, the vegetation does not emit flames and steams, and evil dragons like to soak in hot springs in the scorching lava. I heard that evil dragons love to eat people. The bones on the ground are covered with blood, and the skeletons on the ground have turned into a thick layer of bone powder over the years. …… These are what they said. They told her deliberately, wanting to see her panic and give her nightmares every day. However, they didn't know that one afternoon when she was a child, her mother hugged her and said this to her. "My Desia, you will meet the dragon one day, don't be afraid, she is your destined lover." * In the years following the loss of Desia, everyone thought she was dead. Later, at the magician conference, a mysterious woman wearing a magician's robe to cover her appearance won the first prize and became the youngest great magician in the world. Just when the Great Mage Badge was about to be awarded, the giant dragon that could destroy heaven and earth suddenly appeared in the sky. Its huge wings covered the sky and the sun, and its vertical pupils were filled with cold light. She fell straight towards the most talented Great Mage. Everyone thought that the future hope of mankind would die under the sharp dragon claws. However, when the dust cleared, they saw a shocking scene. The giant dragon landed on the ground and entangled its body, as if guarding a treasure, encircling the great magician in the middle, and there was a trace of tenderness in its eyes. The great mage finally took off her hat, revealing her long purple hair. She rose into the air and landed on the dragon's back. She patted her lover gently and said softly. "Let's go home."
