The True Strength of a Ninja (Naruto Fanfic)
Sakura Haruno was your average fan girl. She focused more on her appearance more than training as a ninja, but it all stopped after her parents death, which was at age 12.
When Sakura's parents died, it was a wake up call, and she was reminded of all the lessons her father and mother taught her.
And she broke one, never let a boy change who you are, so she suddenly changes, which surprises a couple of people.
