I like you, but i dont know why

When i took your hand in the middle of the crowd i felt complete, when i saw your eyes smiling back to me, i felt again complete. But i dont know why, you've something special in that cute and sweet look, smile or what ever it is, i like something about you, but i dont know what is, if it is the sweetness in your look, the cuteness of your voice, or that you care about me.
