This film is loaded with tin man symbolism (Rain's [RAIN!!!!!!!!!!!!!!!!!!!!!!!] mask goes from a standard rabbit, to a more metallic tin man type one. The female victim who thinks she's a cyborg (standard programming, see Angelina Jolie and others) hears voices when using some machine (see above) and it essentially programs her for assassination (unsuccessfully), the voice tells her as a cyborg she must lose specific emotions/actions (which it calls 'the seven deadly sins', standard using a real thing with fake elements to confuse the victim) like sympathy (main one), feeling lost, daydreaming, guilt etc, and note the picture of the cat in the book. The green padded cells featured on above movie poster for it. Below video is one method of programming a "random" school shooter; make them think they're a cyborg, destroy their emotions so will feel nothing when it comes time to pull the trigger, program them to dissociatively remove the physical guns from their hands and make them think their fingertips are where the bullets are coming from.
Standard MK themes also feature like electroshock usage to compartmentalize memories (it's set in an insane asylum, a lot of programming takes place in these places around the world). I'm always amazed when I catch random movies like this at 1:30 AM that fit so well with the themes of my blog. The actress (stroke model) who plays the insanely cute protagonist won a best actress award for her performance in A Tale of Two Sisters. The first part of the entire movie is embedded below; here's another obviously MK symbolic movie (Spy Girl) which has major checkerboard usage (at 4:11).
The film takes place in a mental institution. Young-goon, a young woman who believes herself to be a cyborg, refuses to eat and instead administers electric shocks to herself. Il-sun, a young male patient hospitalized for anti-social behaviour and schizophrenia, who believes he can take other peoples souls, befriends Young-goon. After Young-goon is given shock treatment, she believes that she has been recharged and fantasizes about killing the hospital staff who had previously taken her mentally-ill grandmother away. In reality, her physical condition begins to deteriorate rapidly. By convincing her that he had installed a food-to-electrical-energy converting unit (a rice-megatron) in her back, Il-sun gets Young-goon to eat.
