Happily ever after?

When you love someone, you become the most beautiful blind person on earth. Your heart is then wrapped in a hermetic glass box. It can see everything around, but never gets aware of any other sparkle or any other bloom from the outside world.

The heart absorbs selfishly within the box every little piece of your body: eyes, hands, legs, brain, nose, everything! You walk around with a mesmerized look, everybody can read happiness in your halo, your hands only respond when softly touching the body of the beloved one, your legs lead you unconsciously to him, the only perfume you want to wear is the one his skin imprints in your entire being after every hug. There is no better dessert in the world like his kisses, his voice is the best song in your playlist and if every night you close your eyes the darkness turns into colours, it's his fault of course. 
Luckily your heart is protected all this time by its shield and the feelings inside will last forever, will grow old and surpass any danger, any cloud, any storm.

But... what if... the box cracks?...
