Squint And You'll See It

Summary: Sirius and his potions partner are trying to brew Polyjuice Potion for class, and he can't seem to figure out why she won't wear her glasses.

Notes: Sirius Black x shy!reader. All fluff, really. This is the most self-indulgent thing I've ever written. I'm weirdly self-conscious about the sounds I make, how loud they are, if they could annoy/distract people, etc. so I wrote this just to comfort myself about it lol. I ended up using Y/N a bunch because using too many pronouns in a row makes my brain bristle so oh well. Still though, this is the sweetest thing I think I've ever written. Enjoy! <3

Y/N squinted up at the blackboard as Slughorn collected the class’s attention once again, and Sirius just about melted. The all-too-familiar scrunch in her nose and the crease between her brows gave him more comfort than he probably should have taken from her struggles to see the properties of Chinese Chomping Cabbage from so far back in the classroom. After an especially rapid flurry of blinking, she scribbled a couple notes on her parchment before fisting her knuckles in her eyes tiredly.

Sirius nudged her gently. As if it wasn’t already, the honey-doe eyes she gave him had his heart overflowing with a plush fondness. 

“Your glasses, love,” he whispered, nodding to her book bag, which hung off of the back of her chair. Y/N looked at it, then blinked twice. The glasses were a new and quite helpful development—one she hadn’t quite gotten into the habit of using yet. She eyed the bag again.

“I’m alright,” she whispered back and returned to her notes. 

Sirius frowned. “You sure?”

She nodded, giving him a light smile. 

Sirius frowned slightly but returned to his notes when Slughorn chided him for having his eyes elsewhere. But how could he be blamed? Only a madman would rather learn about ingredients than watch her. 

For a surprisingly long while, Sirius managed to stay focused on his notes, sometimes copying Remus’s, who sat on his right side, and only occasionally sneaking glances at Y/N, who sat on his left. After what felt like an eternity, Slughorn finally let the pair work on their Polyjuice Potion at a work table in the far back of the classroom. Sirius had come down with a nasty case of spattergroit several weeks previous and missed a week and a half of the brewing process. Unfortunately, Y/N had missed several days herself due to a family matter (now resolved with nothing to worry about, she had assured Sirius countless times), ending in the complete devastation of their original Polyjuice batch. And so, Y/N, unwilling to take a bad mark, and Sirius, ready to do just about anything to keep spending time with her, decided to make another batch. 

“Do you want to gather the ingredients or shall I?” she asked as Sirius scooted his stool closer to hers (to better reach the cauldron, of course).

“I can get the ingredients,” he said, flashing what he hoped was his most charming smile, and she blushed.

“Alright, I’ll, erm … I’ll work out our next instructions …” Sirius nodded as Y/N fell into her reading, smiling to himself as her brows furrowed once again to scan the page. 

Sirius skirted the classroom towards ingredient shelves, passing by James, Peter, and Remus, who all raised their brows at him with smirks. He simply rolled his eyes, rummaging through the shelves until he had gathered the correct ingredients. But when he turned around, ready to make his way back to Y/N and their Polyjuice Potion, he was met with a horrible sight: Remus, holding a tight-lipped frown in a near-futile attempt to ward off a smile, Peter, doubled over with laughing cramps, and James, turned around in his chair and arms wrapped around himself, raking them up and down his back in a sultry fashion as he pretended to make out with someone. 

With a peeved sigh, Sirius chucked a bundle of knotgrass at James, seed pods bursting and small nettle-like seeds clinging to James's hair. Of course, the three burst into peals of raucous laughter. Sirius groaned, and quickly made his way back to the back work table as Slughorn chastised the rest of them.

“Sirius, are you alright? You’re looking a bit … erm, warm.”

Sirius’s ears burned even hotter, and his eyes flew to examine the grout between the floor tiles.

“Yeah, yeah, ‘m perfect, lovie.” He set down his armful of glass jars and clay bowls, trying desperately to change the subject. “Found what we’ve got to do yet?”

“Mhm,” she hummed. “Just here, it says we must add three bits of boomslang skin—”

“Got that here.”

“—crush the bicorn horn and add that—”

“Got that as well.”

“—and then there are some cooking instructions, but we can cross that bridge when we come to it.”

“Sounds good to me, love.” Sirius smiled warmly. 

The two worked in harmony, Y/N checking and double-checking that she was measuring everything correctly and Sirius adding the ingredients once she had prepared them. The two worked in sweet, warm peace, managing only one easily-averted disaster, all while keeping quiet as Slughorn continued to teach the rest of the class. There was a strange sort of domesticity to it that made Sirius’s heart skip beats, and he imagined himself with Y/N in their future home, huddled around a cauldron and brewing something to keep them warm on a Siberian night—

“How long should it be at a high temperature again?” Sirius asked, forcing himself from his daydreaming and adding the crushed bicorn horn.

“Erm …” Y/N’s nose practically brushed the page with how closely she peered at the instructions. With the smallest sound of annoyance Sirius had ever heard, her head moved to allow her eyes to travel along the far wall, where a dozen or so posters displayed recipes for a variety of potions. She sighed lightly, squinting heard and pushing herself on tiptoe (as if it would help).

“Use your glasses, love,” Sirius suggested but was quickly brushed off.

“‘M fine, really,” Y/N murmured, eyes still squinting. 

“Sweetheart,” the word caught Y/N’s attention, and she fell back onto her heels, eyes barely meeting Sirius’s before drilling into the bubbling cauldron, “you’ll give yourself a migraine. Use your glasses.” Y/N glanced uneasily from Sirius to her bag on the back of her chair and back. Sirius’s brows furrowed. “What is it, love?”

Y/N shook her head. “Nothing, it’s nothing.”

“Then … wear your glasses,” Sirius reasoned, and she let out a little huff. “Why don’t you want to wear them, lovie?”

“It’s not that I don’t want to wear them, it’s just …” Sirius watched her with soft, almost concerned eyes.

Y/N sighed, pushing herself onto the stool with knees pressed together. The thought was silly, but she had known Sirius long enough to know he wasn’t going to let this go. 

“The buckle on the bag, it’s …” Sirius’s knee knocked gently against hers. “It’s loud—it clatters about when I open it. Catches people’s attention. And my glasses are in the bag, so if I open the bag, people will stare, and then people stare at me when I have my glasses on anyway—not that I’m not grateful for the glasses! They’re a great help for seeing the board during cl—”

Sirius couldn’t help but let out a small chuckle, and he almost felt bad at the pout Y/N dealt in return. “First of all, love, people stare at you and your glasses because you look fucking divine when you wear them. I should know.” He brushed her arm playfully with his, and she flushed a brilliant shade of red-pink. “And second, no one thinks anything about your loud bag buckles, I promise.”

Y/N rolled her eyes. “I just—I don't want to disrupt them is all …” 

Sirius chuckled again, but still, Y/N didn't make a move for her bag. It took only a moment and a half of contemplation before Sirius burst into the most fake-sounding fit of coughs ever created in the history of this Earth. Nearly the entire class turned to stare at him as he seemingly hacked up a lung, and he hung himself dramatically off of the table’s edge to play it up just that little bit more. 

“Mr. Black, are you quite alright?” Professor Slughorn asked, eyes slightly wide with concern.

“Y-yes, Pro—” Sirius coughed a dozen more times, discretely winking at Y/N, who seemed to get the point and quietly retrieved her glasses from her bag. Not a soul noticed.
