Although the English sub translation for the inherited genetic disorder is "Remington" disease, undoubtedly the screenwriter meant Huntington's disease where usually symptoms first appear when a person is in their 30's or 40's and the symptoms are both physical, cognitive and psychiatric. The symptoms displayed by Se Eum's mother match those spelled out in Mayo Clinic's description of the disorder. There is a 50% chance of inheriting Huntington's from a parent who has the defective gene.
