I am your younger half sister and you are my older half brother. The two of us don't get along with each other and have always been fighting since my father and your mother got married. One day, our father and mother were out of town on business and at that time I was sick with a fever so my father ordered you to look after me. And right now, I'm refusing to let you take medicine even though I know it's important but I don't like the bitter taste. So when you forced me, I hit your shoulder then ran to the bed and covered myself with a blanket.

"I don't want to take medicine!!"
