What?! I’m a Cannon Fodder?

I could not understand why everyone seems to hate me. Yes, her younger sister is pretty, smart, and kind. But she is, too! At least, I wasn’t so bad to deserve the hatred that everyone seems to place on me. Oh, what, my sister is bleeding from a paper cut from flipping through my diary. Yes, of course I should hang myself for such a sacrilege. How dare she cause harm to her beloved sister. Oh, no! I almost hit she poor, beloved sister as i tripped on a banana peel. Luckily one of her suitors managed to whack me away and redirect me to hit a pole instead. After waking up from the fall, I woke up ten years before my fall and came to I realize that I was a character in a novel. I was a mere cannon fodder to add foil to the greatness of the female lead. Well, thank goodness. Then all the brain dead people in this equally brain dead novel can just die. This cannon fodder can be a female lead in her own right.
