"Psychopath Diary" Teases Duality Of Yoon Shi Yoon, Jung In Sun, And Park Sung Hoon In New Character Posters

Oct 28, 2019

tvN’s “Psychopath Diary” has revealed new character posters for the main cast!

The drama is a comedy thriller about a man named Yook Dong Shik (played by Yoon Shi Yoon), a timid pushover who happens to witness a murder. While attempting to flee the scene, he suffers an accident that causes him to lose his memory. When he wakes up and discovers the murderer’s diary — which describes his crimes in detail — in his hands, Yook Dong Shik becomes convinced that he is a psychopathic serial killer.

October 29, new posters were revealed for Yoon Shi Yoon, Jung In Sun, and Park Sung Hoon, showing two different images of each character.

Yoon Shi Yoon gives off a cold aura in his poster, which is labeled, “A pushover who thinks he’s a serial killer.” Holding a red diary in his hands, Yoon Shi Yoon wears a cynical smirk on his face. The image beneath shows Yoon Shi Yoon holding not a diary, but a tape labeled “Thriller.”

Jung In Sun’s poster describes her character as a “passionate neighborhood police officer.” Wearing a casual blazer in one image and her police uniform in the other, she wears a stern expression with her hands on her hips.

Park Sung Hoon flashes a gentle smile in his poster, though his smile doesn’t reach his eyes. His clean-cut black suit stands in sharp contrast to the image beneath, which shows him wearing a blood-covered poncho. The poster reads, “100 percent pure psychopath.”
