Sera glances into the silhouette of 'The one who died standing on the brick wall.' Detectives are tongue-in-cheek, calling it a bizarre case, and Pil-joong, who works in the film industry together, spreads trivial rumors and adds that he doesn't know why he committed suicide unfairly. Sera asks "Would it have been less unfair if you killed at least one person?" unravels the inner side of a character full of resentment, anger, and 'han' in a black comedy way.
