At night, outside the palatial castle illuminated by various lights, a group of photographers was fighting with mosquitoes. They were told to guard every exit in order to capture the photo of the mysterious singer Muli, who appeared in the castle that night.
However, although they had stayed up the whole night, the party was long over, the lights had all gone out, and the gatekeeper had also already locked the gate, they still didn't see any suspicious people. There were no cars on the scene, and everyone was picked up by the horse-drawn carriages. It was as if Muli had disappeared inside the dark castle.
