AN: Diabolik Lovers oneshot. Might continue with another chapter if people request it. Takes place after Ruki's Vampire MB ending (the good end) so Ruki and Yui have confessed to each other. Heavily inspired by the conversation they share in Ruki's Sleeping Vampire.
Dream Journal ~
"What high maintenance Livestock. You overdid it again." Were Ruki's immediate words upon entering the room.
A figure was slouched onto a vanity table, which was being used as a makeshift desk. Open books were sprawled chaotically beneath her, a few having fallen onto the ground. Ruki sighs as he steps forward, leaning down and picking one up. He glances at the mess of light blonde hair, tossed around her shoulders and curling at the ends. Yui's arms were bent underneath her, cushioning her head. He peered closer, noting her closed eyes- chest rising and falling with slow breaths. Ruki hums softly in amusement, placing the discarded book on a free space.
"Last minute cram sessions aren't your style...were you really so anxious about the test that you'd pull an all nighter?" He asks the unconscious girl.
At least, he assumes that was what had happened. A quick glance at the bed showed that she must have at least attempted to sleep, judging by the rumpled covers. She'd requested that she sleep in her own room for the night to study, and he'd allowed it on account of how desperately she'd asked, wanting very much not to be distracted. If she was going to burn herself out like this though, Ruki doubted he'd allow her to sleep alone again.
He leans down and smooths the covers back into place, wondering why she hadn't come to him about her study worries. His methods of teaching were...unconventional perhaps. But she enjoyed them. He knew she enjoyed them.
Ruki stills as his fingers brush something, which was sticking out from under her mattress. He raises a brow and pulls out the book- no, journal, from its hiding spot.
He straightens, looking at it and then glancing at Yui. Interesting.
"You don't usually hide things…" he says, weighing the book in his hand. It had her name scrawled in the bottom corner. He opens the first page- just for a peak at the content, and found that of all things, it was a dream journal.
Ruki scoffs quietly. Of course his fanciful Livestock would keep something like this, but he was surprised she'd managed to withhold anything from his notice. What's more- why hide it? They were dreams, nothing more.
His thumb rubs at the spine of the book consideringly. Privacy wasn't something his Livestock ever received, and reading personal notes felt beneath him. It was just a stupid, fanciful book- full of random thoughts, sensations and images she'd seen while asleep. And yet…
With another glance at Yui, who slept on, he opens the journal, turning to a random page.
The date shows that the entry was from three weeks ago. Ruki's eyes skim over the words, beginning to read.
'Had the most wonderful dream!' Yui's neat handwriting informs him. 'I began it not knowing where I was, and at first I was worried. Mist surrounded me, and it was hard to see a hand in front of my face. I didn't know where to turn…' Ruki raises a brow, curiosity piqued. '..and then a big soft cloud met my feet and pillowed against my back! It raised me into the air and I felt so peaceful and safe~'
Ruki's eyes narrow, and he raises his head. She even dreamed childishly. His blue-grey eyes shift to her in annoyance. There he was, doing something underhanded, and she didn't even have the decency of writing something worth sneaking a glance at.
He sighs and moves to another entry, finding one from a week ago.
'Had a terrible craving all night,' this one began, and Ruki shifts, sitting down in an armchair as a different kind of curiosity taking hold. 'My dream was completely to blame. I had been tossing and turning all night- Ruki-kun hadn't been very pleased.' He vaguely recalls that night. They always slept in the same bed, and usually she slept peacefully. On that night, she'd kicked his shins and wriggled, until his fangs had sank into her neck.
'I couldn't tell him what I'd been dreaming, I'd have been too embarrassed.' She continues. 'I felt bad enough as it was- that my temptation had affected his sleep.' Temptation? His eyes darken a touch as he shifts in his chair. She wouldn't...write down an illicit fantasy, would she? No. That, he knew to be preposterous. Yui could barely admit to blushing when he drank her blood, so the idea was ludicrous.
'But in the dream- I'd been feeling so needy. My lungs had hurt and legs ached as I ran towards something, starving. It had been a 'feeling' dream, so it felt like I was really there, sprinting through a forest. I eventually found a house in the middle of the woods- and went straight to the bedroom. Ruki-kun was there, asleep, looking as if he were waiting for me.' He curses his fingers for tightening slightly on the book. 'I'd been breathless but so happy. Finally I walked towards the bed and leaned down, taking a bite of the bedpost-'
Ruki blinks and rereads that line. Bedpost. Yes...that's what he'd thought it had said. '-which was made of chocolate! The whole house was made of candy, and Ruki-kun soon woke up in the dream, very angry that I was destroying his house. I felt so gluttonous.' He snorts at that, and flips back several pages, eyes narrow. He supposes he only had himself to blame for getting interested in that one.
As he continues to read, however, Ruki begins to take notice of something. The thought started small, but then gradually built the more pages turned.
The dreams featured many things, flying, falling, hunger, confusion, fear, sadness, happiness. The nightmares gave him pause, but his hand slowly moved to skip those sections, smelling the vague scent of tears left behind on the pages. She spun many tales about his brothers, sitting together in the living room, watching movies, out at the mall- or innocent picnics shared as a group on a sunny day. Never though, did she write about...them. Her and him, together, alone.
His lips thin. It wasn't like him to be so petulant. Or maybe it was, she had the irritating habit of unearthing things in him. Ruki shook himself, but the feeling persisted. Was she perhaps, dissatisfied with something? The very reason he'd opened the damn book in the first place had been because he remembered someone suggesting that dreams revealed hidden desires.
Did she not crave him at all? Even just writing about a kiss, a shared, intimate conversation would be enough to sate him, but there was nothing. Just the safety of a happy group. Ruki closes the book, a dour expression on his face. Such a happiness should be enough. It was enough, he reminded himself. He'd stolen Eve from her Adam, and now every day was one they could spend together. But...he wasn't called the Snake for nothing, he'd always been a greedy man.
Ruki returns the book under her mattress, righting the covers. That was the problem with nice people like Yui. She spread her warmth around- wanting everyone to be happy. It made knowing if she regarded him differently from everyone else difficult. It didn't matter how much he bit her- forced a blush to her cheeks, or an unwilling moan from that innocent, sinful little mouth... he still remained none the wiser if she truly desired him. And Ruki refused to admit that he wanted her to do more than that.
He wanted her sleepless with the thought of him, need between her legs, and a sharp ache buried so deep that it spilled out along her veins, darkening those rose-pink eyes. He wanted her back arched, fingers reaching- clawing for him as something hooked low in her stomach, the consuming heat becoming an intangible web of visceral, raw need. Ruki wanted.
'Did you finally become corrupt?' He'd asked her that once, but he didn't truly believe she was like him in that regard.
He straightens and turns, crushing his own fantasy under his heel as he leaves the room.
A soft touch, and warmth stroking her head rouses Yui from sleep. Tired eyes peel open, and a soft noise escapes her as the warmth fell away. She sits up from her chair, wincing and patting her back as she blinks dazedly, looking up.
"Oh, Ruki-kun. Good morning." She smiles, tilting her head. "Were you just…" she trails off, hand rising as if to touch her head, before she thinks better of it and fiddles with her messy hair.
Ruki raises a brow, setting down a breakfast tray on her bed, which was filled with food. "Was I what?" He asks, voice his usual calm, lulling tone wrapped in steel.
Yui shakes her head and stands, stretching. "Nothing. Ah, I overslept. I'm sorry…" she glances at the vanity table and sweat-drops. "Aha...I may have over done it." Giving a weak smile, she climbs onto the bed, thanking him for the meal.
Ruki hums. "It seems you lack the self-discipline to know when to stop, Livestock. There won't be a repeat of last night." He hands her the chop-sticks, watching as she waves it off, the tired lines around her eyes catching and holding his attention. She blinks as she holds her bowl, returning his gaze.
"Is something wrong, Ruki-kun?" She asks.
Ruki starts, and takes in the sight of her. Her white nightgown was dipping slightly off her shoulder, several blond stands were sticking up in different directions in her dishevelled hair, and her face held traces of weariness from overworking herself- and yet warmth settles the empty cavern of his chest.
Ruki silently folds something away inside himself. It didn't matter. He didn't need her to crave him with the same dark, twisted want he felt. She was his Eve. Her presence alone did something to him. It was the reason why he'd broken his word to the man he'd respected most in the world, and stolen her away.
His shoulders relax slightly as he takes a seat on the bed next to her. "I'm fine. Your concern for your Master is noted." He smirks slightly. Once, her concern would have sickened him.
Her cheeks redden a touch and she distractedly continues eating, happiness shining in her scent. Ruki picks up his coffee cup and contents himself with the beverage until she finishes eating.
He then calmly sets it down, glancing at the window and seeing soft rays of sunlight filtering in through the glass. "So. The bedpost will have to be replaced." He utters casually.
"W-what? Did something happen?" She blinks, alarmed.
"Yes," he shifts, lips tilting up slightly. "A greedy Livestock got into the house and started eating the furniture, thinking it was made of chocolate. Bizarre really."
He was rewarded with her face flushing red, and her hands sprang up, waving uselessly in the air. "Oh no!" She exclaims. "H-how much did you read! I can't believe you found them!" Yui squeaks.
Them? Ruki's expression doesn't change. "I read enough." He says.
Yui fusses with her breakfast, hands shaking as her beet red face turns pointedly down, gaze fixed firmly on the empty bowls. "I-I'm so sorry, Ruki-kun." She murmurs softly, squeezing her eyes shut, "Please don't be mad- oh but I would be if I was in your position. I just- when you bite me sometimes, I suppose my brain gets carried away- but that's no excuse!" She ranted, biting her lip.
The moment she tries to move off the bed, his hand takes hold of her chin. Ruki leans down a touch, breath fanning over her cheek as his eyes bore into hers. "I want you to tell me what it is you've got to apologise for." He mutters, voice pitched low.
"F-for the journal of course. To think that you read it…" she trails off, eyes conflicted and guilt ridden. "I knew I'd become quite strange since getting involved with vampires, but to write down those dreams, I really have changed into someone ...lewd." She sighs, rubbing her eye. She stills as his thumb runs over her bottom lip.
Ruki leans in closer and smirks. "And just what kind of dreams were those?" He asks in silken tones.
Yui starts and rips herself away from his touch, eyes wide. "Y-you didn't read it after all?" She breaths, voice thin. Her knees then frantically move- nightgown getting caught around her legs and sending her off the bed, landing with a yelp and a 'thump.'
Ruki glances over the side of the bed calmly, smiling as her tangled limbs right themselves. Yui springs to her feet. "Well then, th-that conversation never happened. It's forgotten. S-so, it was the normal one you found?" She asks, smile straining on her face.
Lean muscle shifts as Ruki's legs unfurl beneath him, rising from the bed with all the predatory grace of a jungle cat. "If floating on clouds and eating houses counts as normal, then yes." He says, stepping closer as Yui takes one back.
The moment she turns to run, a hand closes over her eyes. Yui feels herself be pulled back and stills, heart beating rapidly.
"You'll show it to me. The other, less normal journal."
"R-ruki, please don't-" she squeaks, inhaling as something wet and soft trails over the shell of her ear, before the scrape of fangs make her violently shiver.
"Show it to me, Livestock. You'll be receiving a punishment either way." He murmurs, voice uttered directly into her ear.
Yui stumbles forward as she's released, giving him a look with her lips press together in a thin, grim line. Her silent disapproval only amused him however. When he remains unrelenting, her shoulders drop, and Yui pads over to the bed, feeling under the mattress. Instead of the brown dream journal from before, she brings out a lilac coloured one.
She briefly holds it to herself stubbornly, but Ruki holds out his hand. With a sigh, Yui reluctantly hands it over, face beat red. She clasps her hands and bows her head, shame fanning into her scent.
Ruki nonchalantly lets the book sit in his splayed palm as he opens it to the first page. His eyes scan over the words as he remains silent. Yui watches as blue-grey slowly darkens, his expression becoming more and more closed off- unreadable. She gnaws at her bottom lip worriedly and clenches her fingers until they turn bone white. He was angry. Well of course he was- she'd written about him in such a terrible way.
He suddenly moves, and Yui looks up at him sharply, wholly unprepared for the lips that crash onto hers. Yui inhales sharply against his mouth, and makes a muffled noise when he takes it further, prying his tongue past her lips. He brushes it against hers, making a shudder run down her spine.
His arm wraps around her waist, pulling her in as he kisses her- pouring all of his unsaid wants into it. Her small hands come up to smooth over his chest, fingers clenching in the material of his shirt. Ruki pulls away, gaze sinfully dark. "Was that kiss more satisfying than the one in the dream? Or are you still dissatisfied?" He asks.
Rose-pink eyes stare back at him dazedly. "I-I um…" Yui breaths out, blushing harder as she nods. "I'd...like more." She confesses smally.
Ruki's lip lifts- flashing a fang at her, before he spins her around- the room falling away and coming back as his study. Yui reels from being teleported with him, starting as Ruki reaches around her, placing the open journal on the desk in front of her. Ruki then grabs her hands and places them flat on the desk, forcing her to lean forward, bent over the desk slightly.
"Then obey your Masters orders- read it aloud." He commands, the words a rush of hot air in her ear as his lips press against the back of her neck. Yui trembles at the feel of his warmth against her back.
"Ruki…" she swallows, looking down at the words she'd written in her own hand. She supposed she'd brought this on herself, though she felt annoyed at the breach of privacy. And yet...another part of her was glad her secret had been found out. Her Ruki dream journal. The pages were filled with nothing but vague and intense dreams, fantasies and desires she'd all confessed, only ever to herself.
After countless nights spent waking from nightmares in a cold sweat, these dreams had been welcome ones. They were...lewd yes, but full of the same warmth she could feel in his hands as they roved over her body. His lips pulled at the seams of her defences- and his teeth unhinged her.
Yui's lips part as she begins to read, the dark figure at her back reveling in the sound of her voice as she spoke the words.
