Who Exactly Am I? -Naruto Fanfiction-

Who exactly am I?

Why do I live?

Why couldn't they take my life instead of hers?

I know one thing for sure, all my life people had called me Sakura when the truth is...

I will never be her.

I'm not her.

I'm just a shadow.

I'm her replacement for our parents to love again and curse.

But I will never take the place of Sakura.

She will always be around.

She will always be my older sister.

Then who am I?

Then why do I act I'm her?

Where did this lie even start?
