DO I NEED TO TREAT YOU AS MY SISTER AGAIN?

Haah...

She's really annoying... and also confusing
It doesn't happened once
It's been happened since the 1st semester
And it was after she's gettin closer with her new friends...
Then, it really annoys me...

What happened to her?
After gettin close to someone.. then he forget me?
embarassing...

I always treat him.. like my own sister..
It started last year... When we were on 9th grade...

But now?
Everytime she needs friend to tell her problems... It was always me
But after her problem solved... She never think of me again

Everytime i ask her.. She always says that i'll always be her brother...

But i think it was only words...

Now i want to ask her again...

DO I NEED TO TREAT YOU AS MY SISTER AGAIN????

PLEASE EXPLAIN IT TO ME.....
DON'T THINK I'M A NICE PERSON... NO
I'M AN ABANDONED PERSON WHO BECAME A BAD GUY....
