First time I ever liked a girl

Oh, first grade elementary school. I remember it was the first time I ever liked a girl. 
She was tall, she had white and soft skin with black and charming eyes and thin sensual lips.
Her hair was long and straight. All that I knew she was perfect and fitted for me.

I didn't know whether it was fortunate or vice versa but when my teacher knew that I liked her, she immediately paired me with her in seat. 
I was so overwhelmed, though for the first time she was a bit shame but soon we were good friends.

She liked to tell me about horror stories and it kinda made me amazed and scared. 
Unluckily, I forgot her name completely since we were only together in the first grade. 
In the next grade she left for another school. 

All that I know now about her now is that she is a Gusti Ayu, the rest I know nothing. 
I wish I could find her in Facebook but it is impossible since I don't know her complete name.
