Reborn as the Heroine's Sister

I'm Cana Blossom, and I've been reborn as Sakura Himawari's adoptive sister.
The Heroine's sister in my favorite otome game called Sunflower Hearts.

'Speaking of dying... isn't my character fated to die during the game's climax, then I'm forgotten because of my insignificant role?'
I twitch, getting my father's attention, finally.
'Right, insignificant... I saved the Heroine's life, and I'm irrelevant?!'
In anger, I huffed cutely, making my father coo at me, trying in vain to coax me into being happy again, misunderstanding that he's the reason I'm upset.
'So, instead of dying, how about no, I will not die, I will protect the Heroine, and I will change my fate!'
Deciding to be uncharacteristically optimistic, I finally smile again, pumping my fist in the air with a giggly cheer.

Prologue: Hate or Love?
(Cana's POV)
As I wait for Pastel, my younger twin sister, I'm sitting on a park bench.
Watching people cross the road, I see the one person I can't decide if I hate or love with my entire being.
'Should I talk to him? Should I not?' I stood up, shaking my head to get rid of my doubts.
I was about to call my sister when a raging horn broke the serene visage of normality.
I glance back at the once ordinary street.
A truck losing control, speeding in the direction of that hateable man.
Before I could stop myself, I ran.
Pushing my first and last love out of the way, the final thing he saw was my conflicted smile before I'm hit by good ol' Truck~san.
I'm sent flying into a traffic light, my broken body falling to the ground.
It was as though I was a puppet who's strings been cut.
Laying there, limp and shattered, my vision blurs as a familiar voice begs me to hang on.
'Why did I do that? I guess this is the last time I can ask myself, Hate or Love?' Those were my last thoughts before I'm surrounded by darkness, then blinding light.
