Is that the girl?

I have never been so concerned about a girl except for her. It started about a week ago, i started concern her in everything. I started to feel that she is the one for me but i didn't have the courage to tell her the truth. I started to talk with her and i founded that we like the same thing, have a common ambition, and many more. And, suddenly it seems that i know her since we still at kindergarten. I know what she's thinking and almost everything. Every times I talk with her face to face, i'll speechless and my heart will pump faster that normal. She is a good girl and for now, i can't give her anything. I'm trying to help her in everything and it seems that she started to trust me. Is that what we call love? I don't know. Can someone tell me?

The name of the girl is secret........ for now.........
