The Hogwarts library was bathed in the soft, multicolored glow filtering through the stained-glass portrait of Merlin. The afternoon light painted shifting patterns across the worn wooden table where Hermione Granger and Adam sat, surrounded by towering stacks of books, half-unrolled scrolls, and ink bottles that glinted like scattered jewels in the kaleidoscope of hues. Dust motes danced lazily in the colored beams, swirling like tiny golden spirits disturbed by the faintest breath of movement. The ancient smell of parchment and leather bindings mingled with the faint, pleasant bitterness of preservation charms and the underlying sweetness of aged wood—a scent Hermione had come to associate with knowledge itself.
Hermione's posture was rigid, her shoulders squared with determination. She had pulled her hair back into a tight ponytail, the kind that tugged at her temples when she frowned too hard—which, at the moment, was very hard indeed. A few stray curls had already escaped, framing her face in soft brown wisps that she kept tucking behind her ears with impatient gestures. Her quill was poised between her fingers like a duelist's wand, ready to strike down any error with merciless precision. The feather trembled slightly with the tension in her grip, and a small ink stain had somehow appeared on her left cheekbone—probably from an earlier, overly enthusiastic note-taking session—though she remained blissfully unaware of it.
Adam, in contrast, lounged sideways in his chair, one elbow propped lazily on the table. His other hand toyed with the edge of a parchment, his fingers tracing absent patterns along its surface. The afternoon light caught the edges of his silhouette, giving him an almost ethereal quality that seemed at odds with his casual demeanor. A faint smirk lingered on his lips, as though the entire study session was some private joke only he understood. His robes were slightly askew, the collar not quite sitting straight, and there was something in the way he held himself—a subtle wariness beneath the relaxed exterior—that suggested his mind was not entirely on Arithmancy.
Hermione inhaled sharply, her fingers tightening around the spine of a massive Arithmancy tome before slamming it open with a decisive thud. The sound echoed through the hushed library, loud enough to draw a sharp glance from Madam Pince, who peered at them over her spectacles from between the shelves. The librarian's gaze lingered for a moment—a silent warning delivered with decades of practice—before she disappeared back into the stacks, her footsteps soft but somehow reproachful.
Hermione ignored her, flipping aggressively to a page filled with dense, angular runes and complex numerical arrays. The parchment crackled with age and magical preservation, each symbol shimmering faintly as if alive. She smoothed the page flat with unnecessary force, her palm pressing hard against the ancient paper.
---
Hermione:
"All right. We'll start with probability matrices."
She pushed the book toward Adam, jabbing a finger at a particularly convoluted problem. Her nail tapped against a rune that seemed to pulse slightly under the pressure, a complex arrangement of intersecting lines that represented magical potential in its rawest form.
---
Hermione:
"Can you solve this?"
Adam leaned forward, his eyebrows lifting slightly as he studied the page. The runes twisted and shifted under his gaze, the magical ink shimmering faintly. After a long moment, he tilted his head. For a brief instant, something flickered in his eyes—not confusion, exactly, but a strange sort of recognition, as if he were looking at something familiar that didn't quite belong here. Then it was gone, replaced by his usual amusement.
---
Adam (teasing):
"Are you sure this isn't the spell to summon a demon?"
Hermione's eye twitched. She rolled her eyes so hard it was a wonder they didn't stick that way. A faint crease appeared between her brows, the kind that always emerged when she was dealing with what she considered willful stupidity—though she knew, deep down, that Adam wasn't stupid. Far from it. That was perhaps what made him so infuriating.
---
Hermione:
"It's not summoning a demon. It's predicting magical energy fluctuations."
Adam drummed his fingers against the table, the rhythmic tap-tap-tap grating on Hermione's nerves like nails on a chalkboard. Each tap seemed to echo in her skull, disrupting the neat mental pathways she had constructed for their study session. She watched his fingers—long, surprisingly graceful—and found herself momentarily distracted by the motion before catching herself and looking sharply away.
---
Adam (musing):
"So… basically summoning a demon, but politely."
Hermione's fingers twitched toward her wand before she thought better of it. Instead, she grabbed an ink bottle and shoved it toward him with enough force to make the dark liquid slosh dangerously close to the rim. The glass was cool and smooth against her palm, still faintly warm from where she had been clutching it earlier. A single drop of ink escaped, landing on the parchment like a small black eye, and she had to resist the urge to apologize to the ancient text.
---
Hermione:
"Write."
Adam chuckled but obliged, dipping his quill into the ink with exaggerated care. The nib made a soft scratching sound as he touched it to the parchment, a sound that usually soothed Hermione but now set her teeth on edge. His handwriting was surprisingly neat—each rune precise, each number carefully formed—but Hermione watched him like a hawk, her critical gaze tracking every stroke. She noticed the way his brow furrowed slightly in concentration, the way his lips moved faintly as he calculated, the way his shoulder tensed when he encountered a difficult passage.
The moment his quill hesitated over a coefficient, she pounced.
---
Hermione:
You might be reading a pirated copy. Look for the official release to support the author.
"No, no—your coefficient is inverted."
She leaned over, her own quill darting in to correct his work with swift, decisive strokes. For a moment, she was close enough to catch his scent—something clean and faintly herbal, like the shampoo from the prefects' bathroom mixed with the subtle musk of old parchment. She ignored it firmly, focusing on the task at hand.
---
Hermione:
"You're going to explode a cauldron that way."
Adam didn't seem fazed. If anything, her irritation only amused him more. He watched her correct his work with an expression that might have been fascination, might have been mockery—with Adam, it was always difficult to tell. The corner of his mouth quirked upward as she drew a firm line through his error and wrote the correct coefficient in her neat, precise script.
---
Adam:
"Well, at least I'd go out in style."
Hermione huffed, resisting the urge to smack him with the nearest book. The temptation was almost overwhelming—she could feel the weight of a particularly thick volume on magical theory within easy reach, could imagine the satisfying thump it would make against his shoulder. Instead, she settled for an exasperated glare that she hoped conveyed the full depth of her annoyance.
Their bickering grew louder, their voices rising despite the library's sacred silence. Madam Pince's glare intensified, her lips pursed as if she were mentally drafting their eviction notice. From between the stacks, her silhouette was visible—rigid, disapproving, a guardian of silence who had tolerated about as much noise as she intended to.
---
Hermione (hissing):
"Shh! Keep your voice down!"
Adam leaned in closer, his whisper deliberately loud. His breath stirred the tiny hairs near her ear, and she had to resist the urge to lean away—or lean closer, she wasn't sure which.
---
Adam:
"You keep your voice down!"
Hermione's nostrils flared. She opened her mouth to retort, but then—
She stumbled.
Midway through explaining a particularly intricate formula, her flawless recitation faltered. The words died in her throat as she became suddenly, acutely aware of how close he was, of the way the colored light from the window painted patterns across his face, of the faint laugh lines at the corners of his eyes that she had never noticed before. Her mind went blank—actually, genuinely blank, a phenomenon so rare that it would have alarmed her under different circumstances.
---
Hermione (stammering):
"So if you multiply the magical flux by the, um… the exponential—oh, honestly, stop looking at me like that!"
Her cheeks flushed as Adam's smirk deepened. She could feel the heat spreading across her face, could feel her pulse beating in her throat, and she hated every moment of it. Hated that he could see her flustered. Hated that she couldn't seem to look away from his eyes, which held a warmth she hadn't noticed before beneath the teasing.
---
Adam:
"Like what?"
Hermione pressed her lips together, but then—against her will—a laugh bubbled up in her throat. She slapped a hand over her mouth, but it escaped anyway, a bright, startled sound that echoed in the quiet library. It was a ridiculous laugh, high and slightly hysterical, the kind that emerged when stress and exasperation and something else entirely collided in her chest.
Adam joined in, shoulders shaking with silent laughter. His eyes crinkled at the corners, and for a moment, the mask of casual amusement slipped, revealing something genuine beneath. He looked younger like that, softer—almost like a normal boy sharing a joke with a friend.
For a moment, the tension between them evaporated, replaced by something lighter. Something almost… pleasant.
Then—
Their hands brushed.
It was an accident. A simple, fleeting thing. Both had reached for the same piece of parchment at the same time, fingers grazing in a touch that sent a jolt of warmth through Hermione's skin. She jerked back as if burned, nearly upending the ink bottle in her haste. The chair legs scraped against the floor with a sound that seemed deafening in the quiet library.
Her cheeks burned pink. Her eyes darted away. She fixed her gaze on a bookshelf across the room, on the gilt lettering of some obscure magical text, on anything—anything—that wasn't Adam's face. Her heart hammered against her ribs, and she pressed her palm flat to the table as if to ground herself.
Adam, in contrast, didn't react at all. He simply picked up the parchment as if nothing had happened, his expression unreadable. But his fingers lingered on the spot where hers had been for just a fraction of a second longer than necessary—a detail Hermione was too flustered to notice.
---
Adam:
"Relax, Granger. I'm not going to hex you for touching me."
Hermione's spine stiffened. The words—so casual, so unconcerned—snapped something back into place within her. She straightened in her chair, lifted her chin, and met his gaze with what she hoped was perfect composure. If her cheeks were still pink, well, that was simply the warmth of the library. Nothing more.
---
Hermione:
"I'm perfectly calm, thank you!"
Adam's smirk returned, faint but unmistakable, before he turned back to his notes without another word. But there was something in the set of his shoulders, a slight tension that hadn't been there before, as if the accidental touch had affected him more than he let on. He dipped his quill in the ink and resumed writing, but his strokes were slightly less precise than before.
The next half hour passed in relative peace. Hermione muttered incantations under her breath, her quill flying across parchment as she double-checked calculations. She worked through problem after problem with mechanical efficiency, but part of her mind kept drifting—to the warmth of his fingers against hers, to the sound of his laugh, to the way the light had caught his eyes. She shook herself mentally and refocused on the numbers.
Adam worked silently beside her, testing equations on scraps of parchment, his brow furrowed in concentration. Occasionally, he would glance up at her—quick, assessing looks that he masked before she could notice. He filled page after page with calculations, some correct, some deliberately wrong just to see if she would catch the errors. She always did.
It was… surprisingly productive.
Eventually, Hermione leaned back in her chair, stretching her neck with a sigh. The muscles there had tightened from hours of hunching over books, and she rolled her shoulders to release the tension. A glance at the clock on the far wall showed that they had been studying for nearly three hours—three hours of bickering and laughing and, somehow, actual work.
---
Hermione:
"Well… that was surprisingly productive."
Adam shot her a wry grin. His quill had left a small ink stain on his thumb, she noticed—a detail that seemed oddly endearing. She looked away quickly.
---
Adam:
"See? Studying with me doesn't always end in explosions."
Hermione rolled her eyes—but couldn't quite suppress the small smile tugging at her lips. It was true, she supposed. Despite his infuriating demeanor, despite the way he seemed to take nothing seriously, he had actually been helpful. His different perspective had illuminated aspects of the Arithmancy problems she might not have considered on her own.
Then—
Her eyes widened in sudden horror. The clock—the clock she had glanced at so casually—showed the time in clear, unforgiving numbers. Five minutes until the lecture. Five minutes to get across the castle.
---
Hermione:
"Merlin's beard—I haven't seen Harry and Ron all day!"
She scrambled to gather her books in a frantic whirl of parchment and quills. Pages fluttered, ink bottles clinked dangerously, and a stack of scrolls teetered before she caught them with a desperate grab. Her bag gaped open like a hungry mouth, swallowing tome after tome in no particular order.
---
Hermione:
"We've got that lecture on Magical Defensive Formations in fifteen minutes!"
Adam blinked, watching her flurry of movement with mild amusement. He leaned back in his chair, arms crossed, as she performed what looked like a controlled explosion of organizational chaos. One of her quills had somehow gotten stuck in her hair, and a piece of parchment clung to her sleeve like a particularly devoted pet.
---
Adam:
"Go. Rescue them before they accidentally blow each other up."
Hermione shot him a look as she stuffed the last of her belongings into her bag. The bag bulged alarmingly, straining at the seams, but she managed to force the clasps closed through sheer force of will. She was already halfway out of her chair, one foot pointed toward the door, when she paused.
---
Hermione:
"We… we'll continue this later. Don't you dare blow anything up while I'm gone."
Adam gave her a mock salute, two fingers touching his brow in lazy acknowledgment. His eyes glinted with suppressed laughter.
---
Adam:
"No promises."
Hermione huffed but didn't argue further, dashing out of the library with her hair flying behind her like a banner. The door swung shut behind her with a soft click, and her footsteps faded rapidly down the corridor—a frantic patter that spoke of someone running late and determined not to show it.
Adam watched her go, chuckling softly to himself before turning back to the table.
His expression shifted—the amusement fading as his gaze dropped to the System screen only he could see. The blue light reflected in his eyes, casting strange shadows across his features. For a long moment, he simply stared at the floating interface, at the words only he could read.
His eyes narrowed at the timer ticking down in the corner. The numbers seemed to pulse—fifteen minutes remaining, then fourteen, then thirteen. Each digit a countdown to something he couldn't avoid, couldn't postpone, couldn't explain away with jokes and deflections.
---
Adam (murmuring):
"All right, duel time. Let's see if I make it out of this in one piece…"
He gathered his own belongings slowly, methodically, as if savoring the ordinary motion. His quill went into his bag, then his scraps of parchment, then the books Hermione had left behind in her rush. He would return them to her later—if there was a later.
The library was silent once more, the only evidence of their study session the scattered parchment and the lingering warmth where Hermione had sat. Adam ran his fingers over the spot on the table where her books had been, where her elbows had rested, where she had leaned close to correct his work. The wood was still faintly warm.
Then he stood, slung his bag over his shoulder, and walked toward the door—toward whatever waited for him in the dueling chamber. His footsteps were soft, measured, nothing like Hermione's frantic dash.
The door closed behind him with a soft click.
The library settled into its usual hush, the stained-glass light shifting slowly across the empty table. The dust motes danced on, indifferent to the absence of the two who had disturbed them. And somewhere in the castle, Hermione Granger was probably yelling at Harry and Ron about being late, completely unaware of the timer counting down in a boy's vision, completely unaware that the study session she had just left might have been—
Well.
The library, as always, kept its secrets.
