Outside, the rain poured relentlessly, pounding heavily on the pavement and filling the air with an earthy, damp scent. The sky had darkened rapidly on her way home, now covered almost entirely with dense, black clouds. Y/N heaved a sigh of relief as she entered her apartment building, ready to find solace in her flat after a particularly long day.
She kicked off her shoes as soon as she was through the door, hastily shedding her damp coat and hanging on the hook to dry. ‘Exhausted’ felt like an understatement; she wanted nothing more than to just curl up on the sofa and unwind for a few hours.
“Long day, love?” a voice rang out from the living room. Y/N spun around rapidly, her heart pounding in her chest at the sudden noise.
“What the fuck are you doing in my flat?” Her arms folded across her chest, Y/N stared down at her ex-boyfriend who sat confidently on her sofa.
“Our flat.” he corrected her, leaning forward and resting his elbows on his knees. The dim light from the lamp on the side table cast eerie shadows across his face, accentuating the smug smirk playing on his lips.
“It hasn’t been ‘our’ flat since I kicked you out six months ago.” Y/N countered; her tone sharp.
“Technicalities.” Sirius waved his hand flippantly.
He reached over to the coffee table, picking up the whisky glass that was already halfway empty and bringing it to his lips. The clinking of ice against glass filled the silence. The dark liquid swirled within the glass as he took a leisurely sip, his gaze never leaving Y/N’s.
Sirius lounged back against the cushions, his legs spread wide, his posture oozing nonchalance. Y/N’s jaw clenched as she fought to regain her composure, refusing to let her cold demeanour slip and let him see how his unexpected presence unsettled her.
“What do you want, Sirius?” she narrowed her eyes at him, “Actually, how did you even get in? I thought I took your key off you the last time that you showed up unwanted?”
“You seem to forget that I know where you keep the spare key,” he swilled the contents of his glass, “I just thought I’d drop by, see how you’ve been holding up without me.”
Y/N silently cursed herself for being so stupid and not removing the key from its hiding spot.
“I’ve been doing just fine, thank you very much.” she replied, her jaw clenching as she forced the words out. Every single cell in her body wanted her to lash out, scream at him and demand that he leaves and never return. She didn't, she crossed the room to sit in the armchair adjacent to where Sirius was splayed out on the sofa.
Sirius tilted his head at her, his eyes raking over her with a mixture of amusement and curiosity. The familiarity of his gaze made her stomach hurt.
“You can’t just waltz back in here like nothing happened.”
“Can’t I?” his voice was as smooth as silk, “I seem to remember a time when you couldn’t get enough of me. Practically begging me to come over and fuck-”
“Fuck you, Sirius.” she spat, her face contorting with disgust.
Sirius chuckled, a cold glint in his eyes as he shook his head at her. Rising from his seat, he sauntered over to the drinks cabinet with an air of entitlement. He grabbed the bottle of whiskey and another glass, setting them down on the table with a dull thud.
“You’ve been ignoring my calls.” he remarked, his tone betraying a hint of irritation between the veneer of indifference. He removed the cap from the bottle and dropped it so it clattered against the table. He filled his own glass, the then other and pushed it towards Y/N.
“Because you keep calling me twenty times a day.” Y/N said hotly, “Move on, Sirius.”
“Move on?” he barked out a laugh, “Yeah, you’d know a lot about that, wouldn’t you?”
“What’s that supposed to mean?” Y/N reached for her drink and near enough drained the glass in a single gulp. The liquor burned as she swallowed it down, but at least it made Sirius slightly tolerable.
“You seemed to have moved on pretty quick when you found someone else to warm your bed.” Sirius finished, his voice dripping with venom.
Sirius’s emotions had suddenly shifted, his cool, calm demeanour switching to cold and hard. His face twisted into a sneer as he looked down his nose at her, his lips curled up in disgust.
“I don’t know what you’re talking about.” Y/N avoided his eyes as she reached for the bottle, refilling her glass.
“Oh, darling, don’t play dumb with me.” his face softening into a sickly, sweet grin, “After all, I’m the one that knows you best, aren’t I? The one who knows all your little secrets.”
“I don’t have any secrets.” she denied, gripping onto her drink so tightly that the etchings on the glass left an imprint on her palm.
“We both know how quickly you moved on to the next as soon as I was out of the picture.”
Y/N’s chest tightened at his words, a surge of anger coursing through her. She refused to let him see how deeply his words cut her.
“That’s rich, coming from you. You’d fuck anything with a pulse. We both know that.”
“That’s not a very nice way to speak about yourself.” Sirius drawled.
“Don’t twist my words. You know exactly what I meant.” her voice was laced with frustration.
The room seemed to crackle with tension as they locked eyes with each other, the air was thick with unresolved emotions and bitter accusations. The rain outside still poured, pattering against the windowpane, a relentless rhythm that mirrored the storm brewing inside. Each tick of the clock served as a reminder of the fragile balance hanging in the air. Y/N’s chest heaved with each breath, her pulse pounding in her ears. In that moment, the world outside ceased to exist.
“You always did have a sharp tongue.” Sirius broke the silence, his tone dripping with condescension.
“And you always had a knack for manipulation.” she shot back.
A flicker of something unreadable flashed across Sirius’s face before he regained his composure, “Is that what you think of me, darling? Just a manipulator.”
“You know damn well what I think of you.”
The accusation hung heavy in the air, and the expression on Sirius’s face nearly made her regret saying it. With a defiant lift of her chin, she looked at Sirius with a stoney expression.
“Get out.”
“Fine.” he said, his voice laced with thinly veiled contempt, “But we both know that this isn’t over.”
Sirius slammed the front door shut behind him – just for old time’s sake.
