I will try to translate. Though the story doesn't make sense.
For the sake of sake, I am just going to call the protagonist's sister... Joe.
Yeon-Ju lost her family when she was 3 years old, leaving only her sister, Joe, to look after and fend for her. At the age of 16, Joe mysteriously committed suicide. Distressed by the loss of her sister, and only family member, the orphan begins to have panic attacks and starts have these abstruse lucid dreams. (This is the part which I can't get...)Enraged, she begins to take revenge on her high school students for some reason I don't quite understand.
