I dozed in my futon waiting for Aoi to come. Nothing was quite as nice as being woken by my beloved little sister. She would knock on the door and turn the knob. I would hear her come in, and the sound of her voice would gently rouse me... is how it was supposed to go.
But Aoi didn't come into my room. Instead, from the door, she said,
"It's morning. Get up already."
How cold! Without a single footstep into my room she barked the words and shut the door. I scrambled out of the futon but she'd already stomped off downstairs. What was with her lately?
We'd always gotten along. However, these days we barely even spoke. It's true I was working more often and she was coming into her own as a young woman, but... I still loved her as my little sister. She seemed to be more irritable as she got more beautiful.
This spring she had started dating someone.
This is where I ought to take command of my little sister, right? She wouldn't like it at first but it's for her own good. It's best to spare her the heartbreak of some dodgy other guy.
The question is how to achieve this..... Then came a night where our parents went on a work holiday, and it was just Aoi and me. Alone in the house together, I can make her do whatever I say. I've got to undo what's taking over my little sister. It appears that their relationship has not yet progressed beyond holding hands, My sister can still be saved.
