I'm the villain in my sister story?

one day after school I Ended up dying saving a little girl running down the street trying to save a puppy, as a truck appeared out of nowhere and nearly drove over the little girl.
I then seemed to have woken up at a unfamiliar fancy place

after finding out who I'm, my head fricking hurt
"I reincarnated as the Villain in my sister's story!"
