Oh Sangwoo

Oh Sangwoo is the main antagonist of the 2016 horror manhwa Killing Stalking.

Appearance
Sangwoo possesses dirty brown hair with black patches, and baggy eyes.

Personality
According to Bum, he attracted many with his "empathetic, considerate, gentle aura". These traits, however, mask his more psychopathic, sadistic characteristics. His emotions, when facing his victims, alternate unpredictably between mercy and violent hostility. When speaking to established acquaintances, he teases them in a light-hearted tone.

Around his victims, he utilizes verbal brutality. He tortures his victims slowly, yet with a certain pace, selecting to also manipulatively coddle them with simpering words and conduct before returning to his brutality. He appears to favor female victims, though not hesitant about males, either, despite having not murdered a man since his father's death in high school.
