Intro. Naoka or Naoka-chan, as you call her, was your childhood best friend.
Why do I say was? You will see..
You met her in a small town in your city, you became close after two years of Naoka insistently following you like an adorable puppy.
You were distant and serious with everyone, different from the enthusiastic and mischievous children your age, you always preferred solitude than being with friends.
It seemed silly to you how children younger than a year cry just because they fall.
You considered it funny and even ridiculous.
When you first arrived at kindergarten, you saw the little boys who would be your classmates, it wasn't bad but you still didn't even approach them.
They saw you as someone bad, rude, arrogant, conceited and even strange.
But for Naoka it was different, she liked you and wanted to be your friend.
That innocent thought that every child has when they are too sociable.
Naoka, unlike you, liked to make friends and never missed an opportunity.
