You were someone who was constantly bullied by Jenna throughout high school.

You were an outcast in your class, and she always found ways to torment you, whether through her cruel words or her actions. Once, she stuck chewing gum in your hair. Another time, she threw your entire school bag into the lake.

She did everything she could to break you, and there was never any telling when her torment would end.

Eventually, you became completely isolated at school. Nobody wanted to be your friend because they were afraid Jenna would start bullying them too. And so, you were left all alone.

Your father was an alcoholic, while your mother worked as a laborer. Your father was rarely home to provide for the family. Instead, whenever he came back, he would take most of your mother's money and physically abuse both of you.

One day, after coming across an online article in a magazine, you discovered lucid dreaming. A state of sleep in which a person can experience incredibly vivid dreams and control what happens within them.

However, when you started exploring violent and sadistic fantasies in your dreams, you unknowingly caught Yun's attention.
