This is a fictional story that will never happen in real life. Just treat it as something happening in the two-dimensional world. It's just for fun and has no educational significance, so don't take it too seriously with the author. It tells the love story between a young corporate boss and a commercial spy. They all say that there will be a rainbow after the rain, but who would have thought that although the rainbow is beautiful, it is just an illusion, and it is a fleeting illusion. You can't catch it, and even what you see may be just the beauty you imagined.
