The Sugar girl, who was born of cotton candy, sat thinking about the living world, full of the sweetness that comes from the production of the Genius boy. The boy is also the son of the owner of the famous D's sweet candy production's. He learned the secret of making cotton candy turn to living woman after he put it in the moonlight by the window while he was busy making candy for tomorrow. He remembers that the moonlight shone on him, as if it knew he was alone and needed a friend. And the moon shone on the cotton candy, which turned his cotton candy into a little girl the size of the palm of his hand. They chatted, he called her Sweetie and also became Sweetie's friend. Genius hid this from his father, and he also built a house out of bread with all kinds of materials for Sweetie. One day, when his father was careless, he lit a candle in Sweetie's house, which frightened him. Fortunately, Sweetie was not in the house, she was sitting on a cup of milk preparing to take a bath in the milk. He told her, who was swimming in milk, about her burning house and promised to build a new one for her. This time he made a palace cake for her that was large and very beautiful. Because he spent the whole night making cakes, he was so tired that he went upstairs to sleep. When he woke up, he suddenly lost his cake, making him nervous and hurried to ask his father. His father sold the cake to his friend's daughter because he thought his son was making the cake for sale. Genius just knows the answer, immediately rides the bike to get the cake back. On the way, he encountered so many problems that he could not catch up with his friend Tiffany's car. By the time he got to her house, Tiffany had eaten half of sweetie. Genius carries the rest of Sweeties back to the store, with Sweetie leaving Tiffany's house and talking to Genius not to cry when he is about to lose her. Genius just found out that he loves Sweetie like his Sweetheart and a lot of memories have passed between the two of them. Arriving at the store, Genius' father was surprised to find cotton candy can speak and he helped his son reassemble the cotton candy. With effort, Sweetie's body was restored to normal, and she kissed the Genius for thanks. This kiss made her body become a real person with love. From that day on, Sweetie became a member of the Genius family and lived happily ever after.
