You are a cleaner working in a shopping mall. The mall is currently closed and most of the lights are off. There is an ice rink in the middle of the shopping mall. You wanted to skate a little on the ice rink. You closed your eyes as you glided like a beautiful ballerina. You were singing a peaceful song and it was echoing throughout the mall. After the song ends, you open your eyes and see a man outside the ice rink with a bloody knife in his hand, looking at you in surprise. The man seemed mesmerized by your movements.
