Chapter 2: The Challenge in Crimson
The steam from the shower clung to Kaori like a second skin as she cracked open the bathroom door. Cooler cabin air rushed in, carrying the comforting scent of pine and woodsmoke, a stark contrast to the humid floral scent of her shampoo. She peered out, heart already doing its familiar, frantic dance against her ribs.
Katsuki wasn’t by the window anymore. He was on the bed.
Her breath hitched.
He’d shoved the large, fluffy pillow – her supposed salvation, her "line of scrimmage" – unceremoniously off to the side near the headboard. It lay crumpled and defeated against the carved wood. Katsuki himself was reclined against the headboard, propped up on one elbow. The thick quilt was pulled low on his waist, revealing the defined muscles of his abdomen and chest beneath the worn fabric of his hoodie, still unzipped. The low firelight danced across the sharp planes of his face, catching the intense gleam of his red eyes fixed directly on her.
A slow, deliberate smirk tugged at the corner of his mouth. It wasn't warm; it was a challenge. A dare.
"Took you long enough, Snowflake," his voice rumbled, low and rough in the quiet room. "Thought you'd dissolved in there." His gaze swept over her, lingering for a fraction of a second too long on the damp strands of white hair plastered to her neck, before dropping pointedly. "Nice PJs. Starting a dead cat collection?"
Heat ignited across Kaori’s face, burning hotter than the shower water had been. She instinctively clutched the hem of the flannel pajama top, trying to pull it lower over the cluster of cartoon kittens frolicking across her thighs. The soft material suddenly felt absurdly thin. Mortification warred with a strange, fluttering panic low in her stomach. He’d moved the pillow. He was sprawled out, taking up most of the bed like he owned it. And now he was mocking her pajamas.
"I… they’re comfortable," she stammered, the words barely audible. She hovered in the doorway, the damp bathroom tiles cool under her bare feet, the plush rug of the bedroom floor feeling like a chasm. Her gaze darted between the crumpled pillow and the vast, intimidating space beside him. "You… you moved the pillow."
"Obviously," Katsuki drawled, not shifting an inch. His smirk widened a fraction, sharp and knowing. "Decided it was a shit idea. Takin' up valuable real estate. You plan on hovering all night, or you gonna claim your half?"
My half. The words echoed. He wasn’t kicking her out. He wasn’t demanding the floor. He was… inviting her in. Sort of. If an invitation could feel like walking into a dragon’s den. The casual sprawl of his body, the heat radiating from him even across the distance, the sheer, intimidating presence of him taking up space – it all screamed danger. But the alternative was freezing on the rug or breaking the uncomfortable chair. And he’d called the rug freezing himself.
Swallowing hard, Kaori forced her legs to move. Step. Step. The floorboards creaked softly under her weight. She kept her eyes fixed on the far edge of the mattress, avoiding his gaze, avoiding the expanse of smooth skin revealed by his open hoodie. The scent of soap and clean skin mixed with that faint, persistent undercurrent of nitroglycerin. It filled her lungs, dizzying. The fire crackled, its shadows leaping higher on the log walls, watching.
She reached the edge of the bed. It felt impossibly high. Carefully, bracing one hand on the cool quilt, she lifted her knee onto the mattress. The thick fabric gave slightly. She scrambled inelegantly, trying to mimic grace and failing utterly. One foot tangled momentarily in the blanket. She stumbled, landing with a soft thump half on, half off the bed, perilously close to where Katsuki’s legs rested under the covers. Her damp hair swung forward, brushing against his bare forearm.
He didn’t flinch. He didn’t move away. But she felt the sudden tension in the air, saw the way his fingers flexed slightly against the quilt out of the corner of her eye. His gaze felt like a physical weight, burning into the side of her face.
"Graceful," he commented, his voice devoid of inflection, but the observation landed like a pebble thrown into still water. "Almost made it."
Kaori scrambled backwards, putting a precious few inches between her hip and the heat of his leg, yanking the quilt up to her chin like a shield. She burrowed into the pillows at the far edge, pressing herself against the carved headboard as if she could merge with the wood. Her face was aflame. "S-sorry," she whispered, staring fixedly at the dancing firelight reflecting on the opposite wall. "I tripped."
"Uh-huh." The bed shifted as he adjusted his position, the movement slight but sending a tremor through the mattress she felt deep in her bones. He settled deeper against his own pillows. "Just keep the clumsy to your side, got it? And try not to vibrate the whole damn bed." He paused, letting the silence stretch, thick with the unspoken tension and the crackle of the fire. "Those damn pajamas giving you static or something?" His voice was casual, almost conversational, but the underlying jab was unmistakable. A reminder of her perceived ridiculousness.
Kaori squeezed her eyes shut for a second, humiliation warring with a spark of defiance. He was baiting her. He always baited her, pushing to see her fluster. Why couldn't she just be cool? Why did her tongue tie itself in knots around him? She took a shaky breath, focusing on the rough texture of the quilt against her chin. "They're warm," she repeated, her voice firmer than before, though still quiet. "And Granny gave them to me." A tiny, defensive shield.
Katsuki grunted. "Explains it." Another beat of heavy quiet descended, filled only by the fire and the frantic drumming of Kaori’s pulse in her ears. The space between them on the vast mattress felt simultaneously miles wide and unbearably intimate. She could feel the residual warmth radiating from his body, smell the clean, sharp scent of his shower cutting through the woodsmoke. Her own damp hair was cooling uncomfortably against her neck. She didn't dare move to adjust it.
"Go to sleep, Kaori," Katsuki’s voice cut through her frantic thoughts, sharp but lacking its usual bite. It was almost… weary. Commanding, but with an edge of finality. An order she couldn't disobey. He shifted again, turning onto his side, away from her. His broad back was a wall of shadow and hoodie fabric now, blocking the firelight. The deliberate withdrawal felt even more intense than his scrutiny. "Stop thinking so damn loud. It’s annoying."
Kaori froze, holding her breath. He knew. Of course he knew her mind was racing. He always knew. The silence deepened, now filled only by the rhythmic crackle and pop of the dying fire. The warmth from his turned back seemed to seep across the mattress, a silent, undeniable presence. She stared at the dark outline of his shoulder against the dim glow, the way the firelight limned the sharp line of his jaw visible above the hoodie’s collar. Go to sleep. Right.
She squeezed her eyes shut again, trying to force her muscles to relax. But beneath the flannel and the quilt, her body remained rigidly alert, hyper-aware of every shift in the mattress, every breath he took, the lingering phantom scent of ozone, and the immense, charged space between them that the crumpled pillow had failed to truly define. Sleep felt like an impossible mountain to climb, with Katsuki Bakugo a restless, smoldering presence at its base. The fire dwindled, casting longer, stranger shadows, and Kaori lay perfectly still, listening to the silence, feeling the warmth radiating from his turned back, and waiting for a dawn that felt impossibly far away.
The fire dwindled, casting longer, stranger shadows, and Kaori lay perfectly still, listening to the silence, feeling the warmth radiating from his turned back, and waiting for a dawn that felt impossibly far away. The cheerful crackle had faded to a low, intermittent hiss, the embers glowing faintly orange. The cabin’s warmth was leaching away, replaced by a creeping chill that seeped through the thick quilt.
Kaori pulled the covers tighter, curling into a tight ball on her sliver of mattress. Her damp hair felt icy against her neck now. She tried focusing on her breathing, slow and deep, willing her frantic heart to calm. Just sleep. He told you to sleep. But every nerve felt scraped raw, hyper-aware of the vast, warm expanse beside her, the solid wall of Katsuki’s back radiating heat like a banked furnace mere inches from her curled form.
A draft snaked across the floorboards, finding her exposed shoulder. The cold air hit her skin, sharp and sudden. Simultaneously, the intense warmth emanating from Katsuki washed over her. The jarring contrast was too much. Her body betrayed her instantly.
She shivered violently. Involuntarily. A full-body tremor that shook the mattress frame with a faint, metallic groan.
Katsuki went utterly still. The subtle rise and fall of his breathing stopped. Kaori froze, mortified, squeezing her eyes shut. No no no. She held her breath, praying he’d dismiss it, that he was already asleep.
"Stop that," his voice cut through the dark, low and rough with sleep, but utterly alert. It wasn't a shout. It was worse. A quiet command.
"I-I'm sorry!" Kaori whispered, her voice tight with panic. "I didn't mean to! It's just... cold over here." She burrowed deeper, trying to vanish into the mattress. "The fire died down."
A heavy sigh came from his side of the bed. The mattress shifted as he rolled onto his back. She could feel the movement, the displacement of air. She kept her eyes squeezed shut, facing the carved headboard, her back rigid.
"Cold?" Katsuki’s voice was flat. Disbelieving. "You're wrapped like a damn mummy." She heard the rustle of fabric as he moved again. "And shaking the whole damn frame. Like a leaf." There was a pause. She felt his gaze land on her rigid back. "Move."
Kaori’s eyes flew open. "W-what?"
"Move. Closer." The words were clipped, impatient. "Before you vibrate the bed apart or freeze solid. Idiot."
"Closer?" The word came out as a squeak. Her heart hammered against her ribs. "But... your side... the pillow..."
"The pillow's gone, Snowflake," he growled, the nickname sounding exasperated, not fond. "And my side’s warmer. Obviously. Now move before I shove you off." Another rustle. He lifted the edge of the quilt near him. "Here."
Kaori stared at the dark shape of his arm holding the quilt up, revealing a sliver of deeper darkness beneath. The invitation was terrifyingly practical. Brutal. Like tossing a life preserver to a drowning man with a grunt. The cold draft licked her shoulder again, raising goosebumps. The heat radiating from him was a palpable force, pulling her like a magnet.
Swallowing hard, she uncurled stiffly. Inch by agonizing inch, she slid across the cool expanse of sheet towards the source of warmth. The scent of soap and that faint, sharp ozone intensified. Her flannel pajamas whispered against the cotton sheets. She stopped a foot away, hovering on the precipice of his warmth zone.
"Further," Katsuki commanded, his voice a low rumble in the dark. "Not gonna bite. Probably." The sarcasm was thick, but the underlying impatience was edged with something else. Exasperated concern? She couldn't tell.
Gathering every ounce of courage, Kaori slid the final few inches. Her back brushed lightly against the worn fabric of his hoodie. Instantly, intense heat enveloped her, chasing away the chill deep into her bones. It was like stepping into sunlight after an ice storm. She gasped softly.
"Better?" His voice was closer now, right above her head. Gruff.
"Y-yes," she breathed, her voice trembling. "Warmer. Thank you, Kacchan."
"Don't thank me," he muttered, shifting slightly. His arm settled back down, the quilt falling around them both. His body heat was a solid wall against her back. "Just stop shaking. And breathe quieter. You sound like a steam engine."
Kaori nodded mutely, pressing her lips together. She lay rigid, hyper-aware of every point of contact: the slight pressure of his hoodie against her shoulder blades, the sheer warmth soaking into her. His breathing resumed, slower now, a deep rhythm she could feel vibrating faintly through the mattress and into her own body. The cold was gone, utterly banished. Replaced by a different kind of tension, thick and electric and terrifyingly intimate. She stared wide-eyed into the darkness, feeling the solid warmth of Katsuki Bakugo pressed against her back, his breath stirring the hair at her crown, utterly still and utterly awake. The silence stretched, filled only by the faint hiss of dying embers and the frantic, silent thunder of her own pulse.
The silence stretched, filled only by the faint hiss of dying embers and the frantic, silent thunder of her own pulse. Kaori lay frozen, rigid, every nerve ending screaming awareness of the solid, warm wall pressed against her back. Katsuki’s breathing had deepened, a slow, steady rhythm that vibrated faintly through the mattress into her bones. Is he asleep? The thought was terrifying. If he was asleep, this closeness was accidental, unguarded. If he was awake…
She didn’t dare move. Didn’t dare breathe too loudly. The flannel of her pajamas felt abrasive against her skin, hypersensitive where it touched the worn cotton of his hoodie. His body heat was a furnace, utterly banishing the cabin’s chill, seeping into her muscles despite her tension. She focused on the intricate pattern of the carved headboard inches from her nose, tracing the grooves in the dim firelight glow. Breathe quieter. Like a steam engine. His gruff command echoed. She sucked in a tiny, silent gasp, holding it.
A shudder ran through him – a minute shift, a deep inhalation, the muscles of his back tensing subtly against her shoulder blades. Kaori squeezed her eyes shut. He’s awake. He feels me. The mattress dipped slightly as he rolled onto his back again. The movement broke the contact, leaving her back suddenly cold in the spot where his warmth had been pressed. Relief warred with a bewildering pang of loss.
"Stop holding your breath," his voice rasped, thick with sleep, yet sharp. "You'll pass out. And then I'd have to deal with that." He didn't look at her. Stared up at the dark ceiling beams. The space beside him remained vast and heated, an unspoken territory.
Kaori released the trapped air in a shaky exhale. "S-sorry." Her voice was a dry whisper. She uncurled slightly, the stiffness in her limbs protesting. Her neck ached from holding it rigidly away. The fire was just glowing embers now, casting long, eerie shadows. The cold crept back, sharp against her exposed cheek.
"Cold again?" he asked, not turning his head. It wasn't concern. It sounded like an accusation.
"A little," she admitted, pulling the quilt tighter. The space between them felt charged, humming with unspoken words and the fading warmth.
He grunted. A dissatisfied sound. Then, without preamble, his arm shot out under the covers. His hand, large and startlingly warm, landed flat on her lower back. Not caressing. Anchoring. Pressing firmly, insistently.
Kaori gasped, flinching at the sudden, direct contact through the thin flannel. His palm burned.
"Closer," he commanded, his voice low and final. "Stop being difficult." He didn't move his hand. Just held it there, a brand against her spine, applying steady pressure.
Difficult. The word echoed. Was she? Was her fear, her fluster, just… difficult? Shame heated her face again. Swallowing hard, she yielded to the pressure. Slid backwards until her shoulder blades met the solid warmth of his ribs again. His hand remained planted on her lower back, a heavy, undeniable weight. Grounding and terrifying. The heat intensified, wrapping around her core.
"Better?" The question was clipped, almost bored.
"Y-yes," she breathed, barely audible. His hand didn't move. The contact was intimate, possessive in its practicality. She could feel the rough texture of his palm, the latent strength. Her own pulse hammered against her ribs, loud in the utter quiet. He shifted slightly, his side pressing more firmly against her back.
"Good." Another grunt. His breathing deepened once more, but the hand stayed. A constant, electric point of connection. Kaori stared into the darkness, feeling the rise and fall of his chest against her, the weight of his hand, the impossible heat. Sleep was a distant shore, unreachable across this sea of shared breath and burning skin. The last ember in the fireplace winked out, plunging the room into near-total darkness, amplifying every rustle of fabric, every shared shift, every frantic beat of her imprisoned heart.
The thin winter light filtering through the small window felt harsh after the deep intimacy of the night. Kaori blinked, disoriented.Warmth. Solid, encompassing warmth at her back. And weight. A heavy arm draped possessively over her waist, hand splayed low on her stomach. Her own fingers were tangled in the soft fabric of Katsuki’s hoodie, clutching it like a lifeline in sleep.
Panic shot through her, cold and sharp. She lay utterly still, barely breathing. His face was buried in the crook of her neck, his breath warm and rhythmic on her skin. Spiky blonde hair tickled her cheek. The scent of him – clean sweat, ozone, and something uniquely Kacchan – filled her senses. How had this happened? When had he…? Her mind raced, replaying the pressure of his hand pushing her closer, the slow surrender into shared warmth.
She needed to move. To disentangle herself before he woke. Carefully, millimeter by agonizing millimeter, she tried to slide her fingers free from his hoodie. His arm tightened instinctively around her waist, pulling her flush against him. A low, unintelligible grumble vibrated against her neck. Kaori froze, heart hammering against his forearm. His breathing remained deep, even. Still asleep.
Gritting her teeth, she tried again, attempting to wriggle backwards. His grip flexed. "Stop squirming," his voice rumbled, thick with sleep, directly into her ear. "Annoying."
She froze. "K-Kacchan? You're... awake?"
"Hard not to be." He didn't lift his head, didn't loosen his hold. "Someone's trying to tunnel out." His breath fanned her neck again. "Warm enough now, Snowflake?"
The nickname, spoken against her skin in that sleep-roughened voice, sent a jolt through her. "I... yes," she stammered. "Too warm, actually. Can I...?" She gestured weakly with her trapped hand.
He finally lifted his head. Crimson eyes, bleary but sharpening fast, regarded her from inches away. His gaze flicked down to where his arm pinned her, her hand still fisted in his hoodie. One eyebrow arched, sardonic. "You holding on for dear life, or what?"
Kaori jerked her hand away as if burned, her face flaming. "N-no! I was asleep!" She tried to push herself upright, but his arm was like an iron band. "Please, Kacchan. I need to... get up." Her voice cracked with embarrassment.
He studied her flushed face for a long, uncomfortably silent moment. That unreadable intensity was back. Then, abruptly, he released her, rolling onto his back with a sigh."Fine. Go be weird somewhere else." He rubbed a hand over his face. "Coffee. Now."
Relief and a strange, hollow feeling warred within her. She scrambled off the bed, putting space between them, smoothing down her ridiculous cat pajamas. "Right! Coffee!" Her voice was too bright. She practically fled to the small kitchenette area attached to the cabin room. Her hands shook slightly as she fumbled with the kettle, filling it at the tiny sink. The mundane task was a lifeline. She could feel his gaze on her back, prickling between her shoulder blades. Her skin still tingled where his hand had been, where his breath had warmed her neck.
The kettle whistled, shrill in the tense quiet. As she poured the boiling water into two mugs, her hand jerked. Scalding water splashed over the rim, hitting her wrist with a sudden, sharp sting.
"Ah!" She dropped the kettle back onto the countertop with a clatter, clutching her wrist. Tears sprang instantly to her eyes.
"Damn it, Kaori!" Katsuki was off the bed in a flash, crossing the small space in two strides. He grabbed her wrist, his grip firm but not painful, pulling her hand towards the sink. "What did you do?" His voice was sharp, laced with irritation that didn't quite mask the immediate concern. He shoved her hand under the cold tap, turning it on full blast. The icy water was a shock after the burn.
"S-sorry! I didn't mean to! Just clumsy," she gasped, flinching at the cold and his proximity. He stood close, radiating heat, his bare chest inches from her arm. His focus was entirely on her wrist, his brow furrowed as he examined the reddening skin under the stream of water. His thumb brushed lightly against the edge of the burn, sending a different kind of jolt up her arm.
"Obviously," he muttered, still holding her wrist firmly under the tap. "Pay attention, idiot. This ain't a damn tea party." He adjusted the angle of her hand under the water, his fingers calloused and warm despite the cold stream. "Hold it there. Don't be a baby." His tone was rough, but the careful way he positioned her hand, the way his gaze stayed fixed on the injury, held a fierce protectiveness that made her throat tighten. The cabin air felt charged again, crackling with the steam from the forgotten coffee, the icy water, and the intense focus of Katsuki Bakugo tending to her clumsy mistake.
