Trama
Ba Reum finds himself acting a lot more violent than before and realizes that it’s getting harder to control himself. He even gets the urge to kill someone. While Ba Reum is terrified that the Yo Han inside him might take him over completely, another murder case occurs that shows the MO of the previous murder cases. If Yo Han wasn’t the culprit of the serial murders, then is the piece of brain transplanted into Ba Reum’s head not of a psychopath?
