The tvN's Wednesday-Thursday drama "Psychopath Diary" has launched new stills of Yoon Shi Yoon going all out in a one-man exhibit towards a mannequin.

The new stills exhibit Yook Dong Shik taking all of his frustration and anger out on a mannequin. From choking the mannequin to grabbing hair and even swinging a violin at the mannequin's face, Yook Dong Shik does his first-class with gritted teeth. However, the mannequin is definitely unaffected by using his attacks and though he tries to be more menacing in his expressions and actions, there's something missing and barely comical in the way Yook Dong Shik does what he does.

The scene includes Yook Dong Shik visiting a break out room. It is almost as if he is honing his looking skills in his faith that he is a psychopathic killer, and it stays to be seen what Yook Dong Shik plans to do as soon as he feels he is ready.

The next episode will air at 9:30 p.m. on November 27. KST.
