Hyun is a genius criminal profiler with a degree in criminal psychology who received an anonymous email that brought him to the crime scene all the way from the United States. The serial killer seems to be sending a personal message to Hyun with the clues he leaves behind, and Hyun wonders if it could be related to an escaped criminal "monster" from his childhood who killed his father and was responsible for the disappearance of his younger brother.

Totally Engrossing!

HELLO MONSTER is extraordinary. The writing is so clever and ingenious. It combined roller coaster mystery and twists, with irony, biting humor, and surprise.. The lead character is intelligent and cuttingly quick-witted, while still being charismatic and sensitive. The female lead is also empathetic . She is intelligent, determined, and extremely likeable. All of the other characters are equally well-rounded and important to the plot. The acting is just flawless.. The lead actors do amazingly, enthrallingly well. The actor portraying the lawyer, a young man showing little or no emotion, is in such tremendous control of his character. And the supporting acting is equally amazing. The editing, the music, the make-up, the cinematography - all equally excellent. This is definitely one of those stories where avoiding spoiler is higly advised. Truly one of the best ever!
