a/n: I have more characters written for this but I’m splitting it up so that it isn’t giant (I’m also lazy…)
senku
senku pretends to be unfazed when you nod off near him, but his mind immediately calculates how to keep you comfortable without waking you up.
he’s used to working alone for hours, so the sound of someone breathing softly beside him feels unfamiliar. but it’s not unpleasant—it makes the space feel alive somehow.
when your head slips onto his shoulder, he stiffens like a startled cat before forcing himself to relax.
later, he’ll make fun of you for “crashing like a dying battery,” but secretly think about it for days.
it was late in the lab, the faint hum of glassware filling the silence. senku had been talking for what felt like hours, explaining chemical reactions with his usual sharp enthusiasm. you tried to keep up—really—but his voice was oddly soothing when he wasn’t lecturing, and your eyes grew heavier by the minute. the next thing you knew, your head slipped against his shoulder.
senku froze mid-sentence, the word “reaction” dying in his throat. “oh, great,” he sighed under his breath, but he didn’t move. the warmth of your cheek against him made his pulse spike in a way he wasn’t ready to acknowledge. he glanced down, watching your lashes flutter as you breathed softly, utterly unaware of the chaos you’d just caused.
after a while, he adjusted the blanket draped over his legs and let it fall over yours too. “what a pain,” he whispered, but the corners of his mouth twitched into a faint smile. maybe the science could wait—just this once.
gen
when you fall asleep on him, gen’s first reaction is amusement. a sly grin creeps onto his face as he tilts his head, “wow, I must be really boring tonight.” but he doesn’t move away—not even an inch.
he’ll watch you out of the corner of his eye, analyzing every detail like you’re some psychological puzzle—the steady rhythm of your breathing, the way your hand twitches slightly in your sleep.
he hums absentmindedly or plays with a strand of your hair while you rest.
when you wake up, he immediately pretends it never happened.
you hadn’t meant to fall asleep—one minute, you were listening to gen talk about his “brilliant psychological insights,” and the next, your head was slumped forward, the warmth of the fire lulling you under. when he realized you weren’t responding anymore, he paused, blinking down at you. a soft laugh escaped him, low and quiet.
“eally-ray?” he murmured, leaning back against the log. “out like a light. and here I thought I was fascinating.” his tone was teasing, but his movements were careful as he shifted just enough for your head to rest more comfortably against his shoulder.
the firelight flickered across your face, and gen found himself staring longer than he meant to. he wondered if you dreamed easily, or if your mind stayed just as restless as his when things got quiet. his fingers twitched, almost brushing a loose strand of hair from your cheek, but he stopped himself with a quiet exhale. “don’t go reading into this, alright?” he whispered, though you couldn’t hear him. “I’m just… being nice.”
chrome
when you fall asleep next to him, chrome’s brain short-circuits. he immediately starts overthinking—should he move? wake you up? or just sit perfectly still until the end of time? he ends up choosing the last one.
despite his nerves, he finds himself softening as the minutes pass. he’s not used to being the one people rely on, and it makes his chest ache in the best way.
he tries to act casual when anyone passes by, but the red in his face gives him away instantly.
later, when you’re gone, he’ll sort through the stones you collected and quietly reminisce about the feeling of you beside him.
you and chrome had been sorting through minerals for what felt like hours, the pile between you slowly shrinking as the night dragged on. your voice had gone quiet a while ago, and he assumed you were just tired of talking—until he felt a sudden, warm weight against his arm.
he glanced down and nearly dropped the stone in his hand. your head rested against his shoulder, eyes closed, completely out. “uh..” he started, panic spreading across his face. he didn’t dare move, afraid you’d wake up and see how red he was.
minutes passed, and his nerves settled into something sweeter. he carefully shifted so your head rested more comfortably. “you really trust me, huh?” he mumbled, a tiny smile tugging at his lips. when kohaku called his name from outside, he hissed, “shh!” like it’d disturb you, then he realized how ridiculous that sounded.
ryusui
ryusui doesn’t mind when you fall asleep on him—in fact, he loves it. to him, it’s proof that even your subconscious can’t resist him.
he’s greedy with moments like these. even if you just slump against his shoulder for a minute, he’ll shift to make it last longer; adjusting his position so you don’t wake up too soon.
if anyone teases him about it, he’ll laugh it off with a flamboyant, “what can I say? I’m irresistible, am I wrong?”
after you wake up and apologize, he waves it off as if it’s nothing significant. yet he stays beside you, just in case you decide to drift off again.
the night breeze was gentle, carrying the faint scent of salt and smoke across the deck. the ship rocked in a slow, steady rhythm beneath the stars, and ryusui leaned against the railing, recounting some grand story. you tried to listen, but his voice eventually blurred into the sound of the waves. before long, your head dipped, and you slumped gently against his shoulder.
for a second he froze. then that trademark grin spread across his face. “ha! can’t even stay awake for my genius?” he declared, tone dripping with mock offense. but he didn’t move you away. instead, he adjusted his arm to better support your head, his movements uncharacteristically careful.
he glanced down at you, the moonlight catching the curve of your cheek, and something in his chest tightened. greedy as he was, he decided not to wake you just yet. moments like this were worth keeping. he leaned his head back, closing his eyes briefly as if committing the feeling of your weight against him to memory.
