PLEASE VOTE AND COMMENT

Y/N sat cross-legged on Mattheo's massive bed, their tongue poking out slightly in concentration as they carefully held the phone case in one hand and a small can of clear coat spray in the other.

The once-plain black case was now a masterpiece—covered in carefully placed lipstick kisses of various shades, from deep crimson to soft pink. Some prints were perfectly shaped, others slightly smudged, but together, they created a chaotic yet undeniably beautiful pattern. And in the center, written in elegant silver script, were the words:

"Property of Y/N Kane."

It was perfect.

Grinning to themselves, Y/N gave the case a final once-over before shaking the clear coat can and pressing down on the nozzle. A fine mist settled over the case, sealing in the kisses and lettering, making sure they wouldn't fade or rub off.

Just as they finished the final coat, the door to Mattheo's dorm creaked open.

Y/N's eyes widened in panic. Shit.

They scrambled to shove the still-wet case behind their back, their heart pounding as Mattheo stepped inside. He looked as effortlessly confident as ever—his dark curls slightly messy, his Slytherin sweater hanging loosely on his frame, sleeves pushed up to his forearms. His sharp eyes immediately locked onto them, then flickered to the scattered lipstick tubes, tissues covered in red smudges, and the unmistakable scent of spray lingering in the air.

His brows lifted. "Alright, what the hell are you up to?"

Y/N blinked innocently, quickly shoving the spray can behind a pillow. "Nothing suspicious."

Mattheo scoffed. "That's exactly what someone suspicious would say."

Before they could react, he lunged.

Y/N let out a dramatic yelp as Mattheo grabbed their wrist, effortlessly prying the case from their grasp. He stepped back, flipping it over in his hands, and as soon as he saw what they'd done, his entire expression shifted from confusion to sheer amusement.

His lips curled into a smirk.

"You kissed my phone case?" he asked, tilting his head, running his thumb over one of the glossy kiss marks.

Y/N crossed their arms. "Multiple times, actually."

Mattheo let out a low chuckle, shaking his head before his eyes landed on the inscription. He read it out loud, voice dripping with amusement.

"Property of Y/N Kane."

He lifted an eyebrow, glancing at them with a knowing look. "Possessive much?"

"Obviously." Y/N shrugged. "Now, whenever some girl tries to flirt with you, they'll see exactly who you belong to."

Mattheo's smirk widened. "Oh, so this is a warning?"

"A declaration." Y/N corrected, their voice dripping with mischief.

Mattheo admired the case, flipping it in his hands before holding it up to the light. The glossy coating made the kisses gleam under the dim lighting of his dorm, and something in his expression shifted—his usual cocky smirk softened, replaced with something far more genuine.

He hummed, his fingers tracing the prints lightly. Then, to Y/N's surprise, he lifted the case to his lips and kissed one of the marks.

Y/N felt their breath hitch.

"You know..." Mattheo murmured, lowering the case slightly, his voice quieter now. "This is actually adorable."

Y/N raised an eyebrow. "Adorable? You?"

Mattheo shot them a playful glare. "Shut up." He flipped the case one more time, inspecting it before pulling his phone from his pocket.

Y/N smirked, watching closely as he slid his phone into the case. Perfect fit.

But what Mattheo didn't realize was that before he arrived, Y/N had slipped a single strand of their black hair underneath the inner lining—right where his phone would rest. Hidden. Unnoticed. Yet still there.

Now, no matter where he goes, a piece of me stays with him.

Mattheo admired the case on his phone, running his fingers over the glossy surface. "You know, you kissed the case so many times..." His voice dropped an octave as he took a slow step closer, "but you haven't kissed me yet."

Y/N rolled their eyes but didn't resist when Mattheo closed the distance, his hands finding their waist as he pulled them in. His lips brushed against theirs, slow at first, teasing, before deepening the kiss with a quiet hum of satisfaction.

When he finally pulled back, his forehead resting against theirs, his grip on their waist tightened slightly.

"You better never take that case off," Y/N murmured, their voice barely above a whisper.

Mattheo smirked, slipping his phone into his pocket. "Take it off? Are you kidding? I'm never letting this thing leave my sight."

Y/N chuckled, feeling utterly victorious.

Good. Because he'd never know just how much of them was really with him.

Forever.
