my cosmic love, my rarest air

Hc that some of Sirius’ habits are actually super unnerving. Like Remus will come home to their flat and Sirius is just sitting in the dark staring at the wall. Or when he lived with the Potters he would dangle like half his torso off the balcony because it gave him a rush. And in the common room fire back at Hogwarts, he’d throw in strands of hair just to watch it curl up and burn with morbid fascination.

Idk about yall but Sirius loves when Remus stuffs his fingers into Sirius’ mouth

taking remus to a science museum is sirius’ equivalent of walking a dog. remus gets excited by everything and talks his ear off the entire time

tiny lil remus with big brown watery eyes and shaky hands going up to ask an even littler sirius if he could play with him and sirius immediately grabbing his hand all excitedly and asking him what he wants to play with first. remus who’s so stunned that sirius would want to play with him he just lets sirius pick and thats how he ends up pretending he knows how to play football at his first day at a new primary school. remus doesn't even care that he doesn’t understand the rules of football because he’s made a friend and its the coolest kid ever (at least to him)

remus struggling with his crosswords puzzles, and sirius sees him and goes "oh hi moons," leaning over his shoulder while eating his apple and immediately gives him the right answers for the current word he's struggling with and three others. then he walks away whistling as if nothing happened and remus is slightly suicidal

remus lupin being that guy who will respond either in 3-4 seconds or 3-4 business days, no in between

every heart-shaped thing mary sees she buys

First year Sirius Black constantly swearing, but in the way where you can tell he's only just learned most of the words and is trying really hard to seem cool

He pauses before and after saying one and makes sure everyone has heard him, he looks at Remus who just nods at him like good job
