I need you.

A simple word that I just feel want to say to you now.
" I need you so much in my life"
This few day, I am wondering how long further our relation can go to.
How long we can stay as best friend.
I know I never will get the right answer.
But I just feel insecure.
I just worry that you will suddenly disappear just like my other important friend before.
You are part of my important friend.
And I really mean it.
