Having an Attractive Guy for a Best Friend

I have the most sweetest, down to earth, best guy-friend in my whole entire world. I hang out with him all the time, and every time I do, I fall for him even more. I could describe his face, aroma, personality, laugh, eyes, smile, etc., word for word, but that would take so long. The thing is, he likes me as well. Why do these things happen? Why can’t it ever be anything more?
