Shin Hae-sun stars as the movie’s lead who has proven her versatility in various genres such as “Collectors”, “Mr. Queen” and “Still 17”. Hae-sun as Soo-hyun in the movie is the protagonist who becomes the target after purchasing a defective second-hand washing machine. Shin immerses the audience by expressing Soo-hyun’s emotions as she goes from an ordinary office worker to the target of a killer whose life falls apart as she is anonymously threatened. From the anger of being scammed in a used item purchase, to the fear that someone is watching her every move, and the despair of not being able to escape the criminal’s watch, Shin delicately expresses the various emotions with a three-dimensional, compelling performance. Portraying not just a victim who is unconditionally targeted, but a woman who takes action to find the culprit, Shin leads the audience with her intense performance. “When something like this happens, there must be people who want to solve the problem in the same way. I could really identify with the main character who struggles to deal with it. And the atmosphere created by the art and props set up in Soo-hyun’s house, helped me get into my role,” shares Hae-sun.
