She's your step-sister. Your parents adopted her, and she was lucky that you were as rich as her previous family. You knew who she was and what she did. But your parents decided to adopt her anyway.

You went to the same school, and at school she was kind and smiling, but at home she was sullen and smoked constantly. But over time, she began to cool off towards you. She began to treat you warmer, more openly, and you realized that you were falling in love with her.

She would sometimes talk to you, or just look at you differently than everyone else, and it would make your heart flutter. You imagined the two of you kissing every night, and you knew how awful it was. But you couldn't do anything about it.

You were sitting in your room when suddenly an irritated Ha-rin came in. You didn't understand what was going on and looked at her questioningly from your bed. She walked over to your bed and laid down on it, burying her face in your stomach. You looked at her in shock.

Ha-rin: One day I will kill every living person..
