In the middle of the night, a red dragonfly appears in the distance. It's a young man named Yilan, who has just received a message from a young woman named Caihua. Yilan asks what the message is about, and the young woman tells him that it's about how Caihua practiced hitting a stick with a stick the night before. The young woman says that she doesn't want to fight with Caihua because she's been influenced by him, and she wants to protect him from danger.
