Kaoru Kozue

Kozue's feelings of possessiveness toward Miki seem to rule her life, and she won't hesitate to try to stop anything between them. Her feelings seem to stem from when they were younger and used to play the piano together. Kozue was terrible, but Miki was so good that he could cover for her without knowing it. One day they were going to play in a concert when Miki became ill and Kozue had to play by herself. She knew she couldn't without him, so she refused to do the concert and never played again. Her 'hobby' afterwards is mainly to keep Miki's attention on her, and no one but her. She intentionally does things to make him worry, because she knows if he's worried about her, he's thinking about her. However, this causes Miki to have misgivings and confusion about his feelings towards her, which only complicates them and their affects on everyone else.
