In an ancient world, there is an ancient castle. There are many roses in the castle. There is a girl who likes to sit under roses and eat delicious ice cream. Whenever she sits under the rose, there is always a big green frog squatting beside her, with big eyes pouncing on him, as if to say, can you give me some delicious ice cream? At this time, the beautiful girl always gives the frog some food, and the frog croakes to express her gratitude to the beautiful girl. What about this time? There are a pair of butterflies flapping in the sky. These wings flap back and forth quietly on the iris, making a beautiful castle more quiet and peaceful.
