Spike loves Rarity; everypony knows that. But why? Is it just because he finds her the most beautiful pony he's ever seen? Is it her mane? Or is it something deeper, beyond just her looks? This question haunts Rarity, and after a certain incident strikes she's determined to find out the answer.
Got the idea for this after watching the scene from The Cutie Pox where Twilight's mane turns to Rarity's. Cover art is The Kiss by Jack-a-Lynn. You should definitely check his other work out!
