I could give you a scientific explanation but it would be merely bla bla bla, to speak about romance I'll try to take you in a trip.
Imagine this "You stand beside a window with lights off, light clothes and looking the moonlight that comes through the window, a man's hand touches your shoulder softly, doesn't matter who but a man, and hugs you from behind. starts to speak to you softly and directly to your ear."
Ok I can't tell how you felt imaging that, in mind, but I can have an idea of the emotions and sensations that's romance.
Want to talk about mind, in the same scene before you turn around and look at the man, turn the lights on and discover the man is just anyone you may dislike by the way he looks like or talks or maybe his behavior, all the magic is gone and thats the labor of the mind, confront feelings and bring us to reality.
We have to learn to live in a balance between mind and romance, enjoy the romance when it's posible, don´t concern about surrounding things or useless prototypes.
So when the reality strucks your life accept it as it comes and give it's priority as necesary.
Keep a healty emotional balance.
