How To Live Someone Else's Life

My name is Shiroko. You don't need my full name because it doesn't matter anyways.
I was born July 12th 2001 as a female. I'm 16.
I grew up to be a good child. I loved my parents and I always tried my best to please them.
I was the best student at my school, I was good at sports, I was pretty, I was popular but it wasn't enough.
It was never enough.
In truth I was just a small, plain and worthless girl who had no reason to exist.
Who only lived for anime, manga and otome games.
So like all the others I got hit by Truck-san, and was reincarnated into a small mob character.
And for once, I'm kinda happy.....
