What is love?

First it was just a smile,
Then it seemed to be only a hug,
After that it was going to little kisses on the cheek,
It continued growing to a not understandable love
Two sides, one thought
Neither of both seemed to admit it
Why not?
Thinking it would get lost if they say it out loud
Meeting up once again
Looking at each other and holding onto the other, like it would be the last time
Still not telling what one of them feels for the other
Being afraid of the end from this
But what is this?
Now it turned out to a kiss, both still don�t seem to understand,
Or just trying to keep those special moments in a hidden dream world?
Is this supposed to be called love, or is love just a dream which doesn�t exist�
