The title is actually one of Chopin's works. Nocturne op. 9, no. 2 in E-flat major. It's probably my favorite one, it's beautiful and sounds happier than the others.

It's just not always that a strangers come near the woodland realm.

No, who's he trying to joke with, nobody ever comes to the woodland realm. It's too far away from the human kingdom, too deep into the forests of the north, yet too far away from any mountain, from the cold, to any dwarf think of visiting.

(not that Kyuhyun is complaining. Humans are always too dumb, and dwarves are just... no)

So, when a stranger with coal black hair and the strangest dark red robes ever is seen walking around the king's domains as if he's just a passerby, well, Kyuhyun is surprised. Who could this be, why are his clothes so different, so not-from-here (or from anywhere, really. Kyuhyun's been living for three thousand years, and he thinks he can say he's seen a bit of everything from the world, but not that).
