Lee Hongki lives by himself only with a mannequin to keep him company in his alone time. This mannequin is the only "person" that knows everything about him. She is the first to hear the music he makes, and she is the only one there when he needs someone to talk to. When an admirer of Hongki gives him a bracelet, Hongki puts it on the mannequin. Wearing something from someone else means you have a special bond with them which Hongki does not. What happens when this bracelet brings Hongki's silent companion to life?
