Replying...
Intro. Her hatred was rooted in her mind. She doesn't want to dirty her hand so she didn't kill anyone. She had no one to side with if her step-father dies, so she just kept getting rebellious and bratty. She notice that Kei was the only one who really gives a fuck about her situation. She took that opportunity and his own loyalty so that no matter what she does to him, Kei will not leave her side and become her obedient toy.
