IT WAS NEARLY 1:30am. marcus had come home from his away match not too long ago, his body aching with that familiar bone-deep exhaustion that only a gruelling ninety minutes on the pitch could bring.
normally, heād go straight to bed. but he knew youād still be up.
he walked down the hallway, his socked feet making no sound on the marble tile, and leaned against the kitchen doorframe.
there you were. sitting crisscrossed on the cold kitchen floor in one of his oversized t-shirts you decided to steal from his closet, completely lost in your own world.
spread out around you were three open books on deep sea marine biology, a laptop glowing with a research paper on bioluminescence, and a small plate containing a bizarre concoction.. sliced apples dipped in hot sauce and peanut butter.
marcus stayed quiet for a moment, just watching you. his dark eyes softened, a tiny, amused smile tugging at the corner of his lips. he shook his head slowly. fucking weird, he thought to himself - not for the first time, but with a warmth in his chest that completely caught him off guard.
āyou know thereās a dining room table, yeah?ā
his voice was low, deep, and thick with that all too well known smooth, quiet manchester cadence. it carried that gentle, relaxed drawl that always made the room feel a little warmer.
you flinched slightly. not because you were scared, but because youād been so hyperfocused youād practically forgotten the rest of the universe existed. you looked up, your eyes wide behind your messy curls.
"the floor has better grounding," you said flatly, as if it was the most obvious thing in the world. "the table has too much wood density. it feels heavy."
marcus let out a soft huff of laughter, rubbing the back of his neck as he walked over to the fridge. "wood density. right. silly me, innit?"
he grabbed a bottle of water, twisted the cap off, and took a slow drink before turning back to look at you. he didn't tell you to get up. he didn't act like you were crazy. instead, marcus folded his long, athletic frame down onto the floor right across from you, resting his wrists on his knees.
he leaned forward, looking down at your little snack plate with a raised eyebrow.
"what's all this then?" he asked softly, gesturing with his thumb toward the plate. "you're gonna ruin your stomach with that, man. serious." he quipped.
"it's sensory calibration," you explained, your tone completely serious as you nudged the plate toward him. "the hot sauce triggers endomorphins, the peanut butter provides fat for protein absorption, and the apple is crunch. it balances the central nervous system." you explain as if it was common knowledge.
marcus stared at the apple slice, then looked at you. his eyes danced with amusement, a genuine, wide smile spreading across his face, showing off his teeth.
"endomorphins, yeah?" he teased softly, his voice dropping into that quiet, husky voice. "you just make these words up to sound clever, don't you? endorphins, mate. endorphins." he chuckled.
"endorphins," you corrected yourself without a hint of shame, waving a hand dismissively. "same thing. try it."
"i am not eating hot sauce and peanut butter at one in the morning," he chuckled, leaning back against the base of the lower cupboards. "i've got training at ten. boss'd kill me if i turned up with an upset gut because my girl's doing food experiments on the floor."
my girl. the casual way he said it always made a strange, pleasant buzz hum through your chest.
marcus settled in, resting his head back against the cupboard door. he looked exhausted - the faint dark circles under his eyes spoke to the high intensity week he'd had, the pressure of the media, the fans, the constant demand to perform at the highest level.. but sitting here on the kitchen floor with you, all of that armour melted away.
"how was the match?" you asked, leaning your chin on your knee.
marcus let out a quiet sigh, looking at his hands. "tough, you know? they sat deep, made it right difficult for us to find space in behind. had to work for it. got the three points in the end, though. that's all that matters, really." he paused, looking over at you, his gaze gentle. "what were you up to all day? just.. reading about fish?"
"bioluminescent anglerfish," you corrected, immediately shifting into high gear. your posture straightened, your eyes lighting up with that intense, unblinking focus that marcus found equal parts terrifying and fascinating.
"did you know that when the male anglerfish finds a female, he doesn't just mate with her? he physically bites into her skin and releases an enzyme that dissolves his own mouth and body until his vascular system fuses with hers. he literally becomes a permanent parasite attached to her body so he never has to be alone in the pitch black of the deep ocean."
silence filled the kitchen.
marcus just stared at you. his mouth opened slightly, then closed. he blinked once. twice.
"..that's dark, you know," he said finally, a quiet, disbelieving laugh slipping out of his chest. "like... proper weird, man. why are you reading that before bed, love?"
"because it's poetic," you insisted, leaning closer. "it's complete devotion. total physical integration.ā
"it's creepy," marcus countered softly, though the corner of his lip was twitching up again. he reached out, his big, warm hand reaching across the space between you to gently tap the tip of your nose. "you're a proper weirdo. absolutely mental."
"you love it."
"do i?" he murmured, his tone shifting into something impossibly tender. he reached out further, grabbing your wrist softly and pulling you closer across the floor. "come āere."
you scrambled forward, crawling into his space. marcus opened his arms and pulled you up into his lap, wrapping his long arms around you securely. he buried his face into the crook of your neck, taking a deep, heavy breath of your familiar scentā vanilla and warm cotton. you felt the deep rumble of his chest as he relaxed completely against you, all the physical tension from ninety minutes of elite football finally draining out of his muscles.
"you're warm." he mumbled against your skin, his voice muffled.
"you're cold," you retorted, running your fingers through his short, dark curls. "you need to regulate your body temperature, rashy.ā
marcus gave a quiet, breathy laugh against your neck. "always gotta have a reason for everything, don't you? can't just be 'cause i want to hold you?"
"that's a psychological reason," you pointed out softly. "oxytocin release."
marcus lifted his head slightly, looking down into your face. up close, his dark eyes were incredibly gentle, carrying that quiet, humble warmth that made him who he was. he looked at you like you were the most interesting, complex puzzle he'd ever been given to solve. someone completely untouched by the fame, the money, or the noise of his world. you were just you. unfiltered, blunt, chaotic, and entirely his.
"you talk too much." he whispered affectionately, though his eyes were full of devotion.
"you asked me about the fish."
"and you gave me a horror story." he teased, his thumb gently smoothing over your cheekbone.
"next time, just tell me they glow in the dark, yeah? keep it simple for me.
"i don't do simple."
"nah," marcus murmured, his soft lips brushing against yours in a slow, lingering kiss that tasted like mint and pure bliss. "i know you don't. wouldn't want you to, either."
he pulled back just an inch, resting his forehead against yours. his hands rested securely on your waist, anchoring you to him.
"come to bed now, yeah?" he murmured softly, his accent rich and soothing in the quiet of the night. "leave the glowing fish for tomorrow. i'm dead beat, and i need my girl with me."
you looked at the books spread across the floor, then back at marcus - his heavy eyelids, his gentle smile, the quiet, safe space he always built around you no matter how loud the rest of the world got.
"fine," you whispered. "but tomorrow i'm telling you about vampire squids."
marcus let out a low, rumbling laugh, shaking his head as he helped you stand up, keeping his arm wrapped tightly around your waist.
ācanāt wait, love.ā he smiled, pulling you close against his side as you both walked toward the stairs.
