There's something about Lu Han, something charming and something unique, but Sehun can't quite figure it out. He's been thinking about it for years, ever since he'd spotted those big doe eyes and soft black hair in the practice room. Now, years later, after they've been told they'd be in the same group, after they'd been roommates, after they'd been separated by oceans and airplanes, Sehun is trying harder than ever to figure Lu Han out. At least just a little bit. Sehun has puzzle pieces, and maybe not even all of them, but he's trying to put the picture together as best he can. But there's another part of the puzzle, one Lu Han can't apparently see, and that's the most difficult part of it all. Sehun knows, he sees it, he realizes it, he just doesn't know why, how, when.
