Chapter Text
Sirius knew that no one could possibly see all that he saw in Remus Lupin’s Smile.
It wasn't like Remus smiled as much as himself or James, or even Peter for that matter. But when he did, when he truly did, Sirius felt like his guts stopped doing whatever they were supposed to do to dance to “Twist and Shout”. Which was kinda annoying, to be honest –it’s what made him spill half of his pumpkin juice on his shirt that one time at second year, disastrously blow up a potion on third year (and having to deal with a really pissed off James afterwards), spilling ink all over his notes during classes for just too many times, and, recently, cut himself in the cheek while shaving (Remus had stopped smiling right away, looking at the blood running down at his neck and mumbling a rather scared 'Padfoot!')
Remus had small, light brown eyes, which got even smaller and circled by those wrinkles Sirius has only seen in older people when he smiled, like they were almost closed. His cheeks were marked with the most amazing dimples, and his slightly crooked teeth were the perfect addition to form, in Sirius’ opinion, The Best Smile in the World.
One day, on fourth year, Sirius spent about thirty minutes smiling (his best smile, that one that made girls in all Hogwarts sigh) to himself in the bathroom mirror. But, as beautiful as it was, it was nothing like Moony’s – it didn’t have half the magnetism, the inexplicable attractiveness, that dancing-gut thing. And then he wondered why all the girls didn’t stop to look at Remus’ smile, while they did to watch Sirius’.
He thought it was probably because Remus was shy, and didn’t usually smile much when girls were around. So maybe Sirius should make him smile when that blonde Hufflepuff he caught Remus staring at was sitting next to them in Transfiguration. Maybe she would notice him, notice the brilliant smile he has, just like Sirius did.
Then he felt a slight pressure on his throat, and some weird sort of feeling he had never experienced before. Sirius finally left the bathroom, frowning, and didn’t even say goodnight to (a very surprised) Remus before he went to bed.
(Sirius didn’t know that when he smiled, Remus’s guts did that same, stupid, dance. Because Oh God, Sirius smiles with his mouth and eyes, with his arms, with his shoulders moving and neck always a little bit stretched, he smiles with his fucking hair for all it was worth. Remus just had way more self-control not to spill juice, or mess up in classes every time he caught a glimpse of Sirius smiling form – which, for his misfortune, happened just too often. He thought that it was probably unhealthy, having your guts doing those weird things inside yourself for such a long time in a day. But Sirius didn’t really help that, did he? And Remus, healthy or not, wasn’t sure if he wanted Sirius to ever stop smiling that much.)
