Yoon Shi Yoon Had Encountered The Serial Killer In “Psychopath Diary” Teaser

"Psychopath Diary" has released a new teaser that interests the viewers. "Psychopath Diary" is set to premiere on November 20 at 9:30 p.m. KST and will also be available with English subtitles on Viki. 

The clip preview show Yook Dong Shik's (played by Yoon Shi Yoon) day begins at work. He is a pushover at work and easily gets bullied by his boss. Yook Dong Shik just fixed his eyes on the floor while his boss scolds him and kicks him in the shin. He meekly apologizes to his boss after doing this. He is afraid of speaking up his mind and of talking back to his boss. 

The newly released video showed Yook Dong Shik going to the rooftop of the building while crying. He wanted to commit suicide. He said, "I don't want to spend the rest of my life being abused like this." He thought that ending his own life will also end his misery. He was tired of being bullied all his life.

Everything changed when he witnessed the company director Seo In Woo (played by Park Sung Hoon) kill someone. He can't believe what he saw and his whole body shivered. Seo In Woo's red diary accidentally fell into Yook Dong Shik's feet when the victim begged for his life. He picked up the diary and escaped the scene fearing for his own life. He ran as fast as he could without even looking back.

As he ran, he was accidentally hit by a cop's car. The cop was Shim Bo Kyung (played by Jung In Sun). When he regained his consciousness in the hospital, the doctor said that he has retrograde amnesia. Shim Bo Kyung gave back the red diary to him before he left the hospital. She said, "Is this yours? It was the diary that I found in my car. I think it is yours." He took the diary even though he cannot remember anything from the incident.

Yook Dong Shik read everything written in Seo In Woo's journal including his gory murders. He now thinks that he was a psychopathic serial killer. Meanwhile, Shim Bo Kyung is making her serious observation about the murder case. According to her findings, the killer must be a psychopath who enjoys murdering people and making it appear as a suicide. The video ended after Seo In Woo said, "I have a secret obsession."
