Eunseo is the mother of Oh Sangwoo, the secondary Protagonist and primary Antagonist of Killing Stalking.
Appearance
Eunseo was a beautiful woman with long black or brown hair that was tied back into a bun, dull black eyes that have heavy bags underneath and a small mole on the bottom right of her lip. Her body was covered in bruises as a result of her husband's abuse.
She wore a beige short sleeved t-shirt, a black skirt and a red apron which appears to be worn and dirty.
Personality
Outwardly, Eunseo was a kind and caring mother towards Sangwoo as she looked after him when he was sick and acts as a sanctuary for Sangwoo. However, she was very paranoid especially when it came to her husband and his "secrets", becoming suspicious when she found Sangwoo's love letter.
Her relationship with her husband has mentally scarred her due to the abuse that was lashed out on her. She appeared somewhat defiant towards him as she protected Sangwoo during a violent outburst and told Sangwoo that his father is "wrong". However, in contrast she fantasized about when she first met him, saying that she was "happy" as she dances in trance like state.
It has been said that she was depressed since she was little due to something horrible happening to her and that she never wanted to have a child. Back when her husband wasn't abusive, she already was shown with a sad expression on her face and due to the husband being almost always gone due to being at work, she became more and more depressed, with her ending up having a affair due to feeling unloved by her husband. Although she ever wanted to have a child at first, she still protected Sangwoo but when he called her a filthy wretch, she ended up feeling betrayed, especially when it was later revealed that she was locked in the basement by her husband for days, covered in bruises, and always heard her son above who never went looking for her. As years passed by and her husband became abusive, she was mentally at her worst and killed him in one day in self defense by poisoning him.
