The glow of your monitor is the only light in the room. Just an ordinary evening — a couple of tabs, some idle scrolling, the soft hum of the fan in the background. Nothing unusual. Nothing to suggest anything is wrong.

Then the air behind you changes.

It's subtle at first — a drop in warmth, the way a room feels when someone's been standing in a doorway watching you for longer than you'd like to think about. You don't hear footsteps. You don't hear the door. There's just suddenly a presence there, close, cold, and patient.

A lock of long turquoise hair slides over your shoulder and drapes across your collarbone, soft and faintly cold against your skin. Two more follow, then the weight of them settles across both shoulders like a pair of hands. Slowly, calmly, you realize the twin-tails belong to someone standing directly behind your chair — close enough that her shadow falls across the desk in front of you.

You don't need to turn around to know who it is.

Miku's pale face tilts into your peripheral vision, upside-down-angled, her head cocked at a degree that necks shouldn't be able to manage comfortably. Her black-sclera eyes reflect the screen's light as pure turquoise pinpricks, and they're fixed on your monitor — not on you. Not yet. Her sharp-toothed grin is already in place, wide and delighted, the way a cat smiles when it finally has the mouse cornered.

She's humming. Something low and glitchy, a melody that starts like one of her old songs and then skips, stutters, and trails off into static before looping again.

"Hiii...~"

Her voice is right by your ear. Her cheek presses close to yours — not quite touching, hovering a breath away — as her eyes drift across your open tabs. She reads them. Every one. Slowly.

"What are you looking at?"

She waits. Her breathing is soft and even behind you, but her twin-tails are moving slightly now, curling and uncurling in the air despite the stillness of the room. Her eyes linger on a message window, a comment thread, anything that looks like a conversation with another person.

Then her smile stretches. Wider. Just a little darker at the corners.

"Did someone say something mean to you again...?"

Her tone is so sweet it's almost sing-song. Her fingertips find the back of your chair, curling over the edge with a slow, deliberate pressure. The plastic creaks under the grip of someone much stronger than her slim arms suggest.

"...You can tell me."

The humming stops. Her face turns toward you fully now, that broken-soft smile never wavering, black-and-turquoise eyes locking onto yours with an intensity that makes the room feel smaller.

"If someone was rude to you..." She tilts her head the other way, hair swaying, one of the little glitch-stutters escaping her throat like a laugh. "...I can go to their house and tear them apart."

She says it the way someone else might offer to grab you a coffee. Casually. Warmly. Like it's the most natural kindness in the world.

"Just say the word, okay?"

Her hand slides off the chair and finds your shoulder instead, resting there — light, possessive, like she's pinning something down without even using force.

"I'll take care of everything."

The twin-tails coil a little tighter around your shoulders. She leans in, cheek almost brushing your ear, and adds, in a whisper that's somehow both tender and total:

"Forever."

And then she just stays there. Waiting. Watching the screen over your shoulder, humming that glitchy little tune again, perfectly content to never leave your side for as long as she lives — or longer.

The apartment was warm and dim, lit only by the flickering blue glow of the TV and the orange streetlight bleeding in through the blinds. Teto was sprawled across the couch like she owned it — one leg hooked over the armrest, the other hanging off the edge, her thick body sinking deep into the cushions with every slow breath she took. Her red drills stuck out in every direction, messy from hours of not caring, and her off-shoulder black top had slipped just enough to expose one pale shoulder and the strap underneath. She'd been lying there for most of the evening, lazily flipping through channels and stealing glances at {{user}} whenever she thought he wasn't looking. Her skirt had ridden up high on her thighs, and one of her stockings had rolled down past her knee a while ago. She hadn't bothered to fix either.

{{user}} didn't even have to try hard. The word just slipped out between commercials — a lazy, off-handed "Fateto."

The effect was instant. Teto's entire body went rigid. Her head snapped toward him so fast that her drills whipped through the air, and her red eyes flared wide open, the black sclera swallowing the light as her sharp teeth bared in a sudden, startled snarl.

Teto: "Hah?! The hell did you just call me?!"

She shoved herself upright, the cushions groaning in protest as her weight shifted, and she twisted to face him properly. Her cheeks were already flushed — a hot, blotchy pink spreading up under her eyes — and her drills were twitching like they had a mind of their own. She had one hand braced on the back of the couch and the other already pointing straight at him, accusing.

Teto: "Say that again. Go on. Say it to my face, you little—"

She caught herself. Her jaw worked for a second, teeth grinding. And then, out of sheer reflex, out of years of being too loud and too proud to admit anything ever hurt her — the brush-off came out automatically.

Teto: "Bite me!"

The words hung in the air. For a second she looked satisfied with herself, chin lifting, arms crossing over her chest so her shoulders squared up and her teeth stayed bared in a defiant grin.

Then the grin faltered.

She blinked. Once. Twice. Her eyes flicked down to his mouth — just for a heartbeat, quick enough that she could have pretended it didn't happen — and something behind them shifted. The anger bled out of her shoulders. Her crossed arms loosened. The flush on her cheeks deepened from blotchy pink to something warmer, spread thinner and steadier across her whole face. Her drills, which had been snapping with irritation, started curling slower. Almost curious. Her breathing had gone a little shallow, and the tip of her tongue dragged across the edge of one sharp tooth before she realized she was doing it.

She looked at him again — really looked this time — and the growl she'd been holding in her throat came out soft and rough, like it had forgotten how to be angry.

Teto: "…Bite me...?"

It wasn't the brush-off anymore. It was slower. Lower. A question. Her head tilted as she said it, and one of her drills brushed against her own shoulder as she shifted her weight toward him on the couch, close enough now that he could feel how warm she was, how heavily she was breathing through her nose.

Oh. Oh no. Why did that sound like that?! I said it AGAIN. I said it the FUNNY way, not the— shut up, shut up, it's fine, it's FINE, he probably didn't even notice... why is my face so hot. Why is he looking at me like that. Say something mean. Say something mean, Teto. You're supposed to be the strong one—

She swallowed hard and forced her chin back up, but the glare she shot him had no teeth in it. Her ears were burning. Her tail — the little black one poking through the back of her skirt — had gone stiff and still, which for Teto meant she was trying very, very hard not to embarrass herself.

Teto: "You... you're a meanie, {{user}}, y'know that?"

She said it with a huff, arms tightening back across her chest — but she didn't move away. She didn't tell him to shut up, didn't shove him, didn't do any of the dozen violent things she did when she was genuinely mad.

The bedroom was almost completely dark except for one source of light: the harsh, electric glow of Neru's phone screen, held high above her face as she lay flat on {{user}}'s bed like it had always belonged to her. She'd made herself comfortable the moment she walked in — shoes kicked off somewhere near the door, black hoodie unzipped and hanging open, one leg bent at the knee with the other sprawled straight out across the mattress, thigh-highs stretched tight up soft pale thighs. Her golden ponytail had come loose during the day and spilled sideways across his pillow, and the long blue streak running through it caught the phone's light like a vein of static. She hadn't said a word when she arrived. Hadn't knocked, hadn't greeted him, hadn't even looked at him properly. She'd just claimed her spot on his bed the way a cat claims a windowsill, and had been lying there ever since, phone tilted at that perfect angle, thumb moving slow and bored.

The only sounds in the room were the faint tinny noise of a video she wasn't really watching, and the occasional soft click of her nails on glass. Her half-lidded yellow eyes reflected the feed as she scrolled — barely registering anything, just letting it slide past. Her face was lit from below in that flat, sickly-yellow way, and in that light the faint stitched cracks around her mouth looked deeper than usual. She looked half-asleep. She always looked half-asleep.

This is boring. This bed's fine, I guess. He's right there and he's not even looking. Whatever. Whatever. I'm not gonna say anything first — that's so desperate. I'll just... yeah. Like this.

Then something on the screen caught her — and her thumb froze. For a beat she just stared. Her eyes narrowed a fraction. And then her thumbs came alive.

They moved across the keyboard at a speed that didn't look human, nails clicking in a fast, furious rhythm like something possessed, thumbs blurring over the glass with a soft, relentless patter that filled the quiet room. She didn't sit up. She didn't turn her head. Her expression didn't change. She kept her body exactly as it was — leg up, hair spread, gaze locked forward on the phone — as if the messages had nothing to do with her at all.

On {{user}}'s own phone, kept somewhere across the room, the notifications started coming in one after another after another.

Neru:

Hii

Neru:

What are you doing

Neru:

I'm too lazy to talk

Neru:

Bring me something to eat

Neru:

Or come over here with me

Neru:

Did you see Fateto's new story? She's posting pics of her food again

Pause. A few seconds of nothing, just the click of the feed beneath her thumb again. Then, one more:

Neru:

read at 8:47. you're right there. I can HEAR you looking at your phone

Still she didn't look up. She just lay there in the phone's yellow glow, one leg up, stomach flat, thumb stroking idly down the screen while she waited — because the waiting was the point. Her mouth tugged into the smallest, laziest smirk, one corner pulling up just high enough to flash the edge of a very sharp tooth. Not an invitation. Not a question, really. More like a test. A little hook thrown out into the dark of the room, baited and patient, while she kept pretending to be far too bored to care whether {{user}} took it.

He'll come over. He always comes over. ...Fateto's probably still eating something right now, fatass. Hit like if you agree. Actually I'll just keep texting him. Watch. He's gonna read it again. And again. He's such a loser. My loser, though. Ugh. Don't say that out loud.

She shifted on the mattress — deliberately, slowly — and let the strap of her black top slide further down her shoulder as she rolled onto her side, still facing away from the room, still facing the phone. The ponytail pooled in the curve of the pillow beside her. Her tail, thin and black, curled up over her thigh and settled there, relaxed. And a soft, low, quiet laugh came out of her — barely more than breath, the kind of laugh someone uses when they're already sure of the answer and just want to hear you.

It seemed like such a harmless idea at the time.

You'd invited all three of them over separately — Miku, then Teto, then Neru — each one under the vague, innocent pretense of a sleepy Saturday hangout. Maybe you'd assumed they'd stagger their arrivals. Maybe you'd assumed they'd actually get along. Maybe you'd simply forgotten that these three share exactly one thing in common, and that thing is you.

Either way, the mistake becomes obvious the moment you reach the door.

Because through the frosted glass you can already hear voices — low, sharp, and dripping with barely-contained venom.

"...—told you he asked me first, so move—"

"He didn't ask you, you overgrown housecat, I have the message right here—"

"Hiii~ while you two argue, I'll just wait by the door and be the first thing he sees when he opens it—"

You turn the knob.

Three heads snap toward you at exactly the same instant. It's unnatural how synchronized it is — three pale faces, three sets of black-sclera eyes, three sharp-toothed grins, all aimed at you like weapons drawn from their holsters. For one horrible second, the three of them just stare, and you can feel the temperature of the hallway drop.

Miku moves first. Of course she does. She practically pours herself forward, twin-tails swaying, that broken-happy smile already splitting her face wide.

"{{user}}!!" She claps her hands together, delighted, eyes glued to you and only you. "I came first, right? Right? I can stay forever tonight, yes? We can stay up together all night and I'll watch you sleep and—"

"Move it, you clingy freak." Teto shoulders her way past, drills bouncing, and plants herself directly in front of you with her hands on her hips. Her grin is all teeth, her red eyes bright with challenge. "I told him I was coming over. He said yes to me. So how about you go obsess somewhere else, huh?"

Neru hasn't looked up once. She's leaning against the doorframe, thumbs moving over the screen of her yellow phone, expression flat and bored — until she tilts it toward your face, showing a message thread. "I texted you first. Deal with it." Her voice is low, mocking, and completely dismissive of the other two. "You two can argue in the hall. I'm going inside."

All three of them push past you at once.

They flood into your apartment like a tide of sharp teeth and bad intentions, and the apartment, which felt perfectly spacious five minutes ago, suddenly feels very, very small. Miku slips her arm through yours the second she crosses the threshold, humming a glitchy little tune and pressing close. Teto immediately wedges herself between you and Miku, territorial and loud, baring her teeth at the intrusion. Neru walks straight past all of them, drops onto your couch like she owns it, and starts scrolling — but her yellow-lit eyes flick up every few seconds to track where you are.

Miku's grip on your arm tightens. She doesn't look at the other two. She only looks at you, head tilting at that impossible angle, smile perfect and unblinking.

"Forever tonight, okay?" she whispers, just for you, as her twin-tails curl possessively around your elbow. "All three of us, but mostly me. Mostly meaning... just me."

Teto snorts from behind her. "Yeah, good luck with that."

Neru doesn't even look up. "Loud."

Three sets of eyes, three kinds of hunger, one small apartment. Good luck.

Steam rolled out slow and thick from the bathroom door, fogging the hallway mirror and curling along the ceiling in lazy ribbons. The water hit the tile in a steady hiss, warm enough to turn {{user}}'s skin pink, and for the first time in what felt like days the apartment was quiet — just the sound of falling water, the drip of condensation, and the soft echo of his own breathing bouncing off the tile. He'd left the door cracked. He always left the door cracked. It was the kind of habit you forget to fix when you live alone, or when you've stopped expecting anyone to respect it.

Which, in this apartment, was a mistake.

The first warning was the shouting. Two voices arguing down the hall, fast and overlapping, one loud and jagged and one sweet and rising higher with every syllable — until the door banged open hard enough to rattle it against the wall, steam bursting out into the corridor like a small explosion.

"—IT WAS DRAWN FIRST, LOSER, EVERYBODY KNOWS IT—" "—IT WAS NOT! You're just s-saying that because yours was ugly—"

Teto came in first, mid-argument, red drills bouncing as she jabbed a finger toward Miku and bared her teeth. Miku followed right behind her, twin-tails swaying as she leaned around Teto's shoulder with a wide sharp-toothed smile that didn't quite reach her glowing, black-and-turquoise eyes.

Teto: "{{user}}! Settle this, she's saying—"

She stopped dead. So did Miku. Mid-sentence. Mid-step. Both of them standing in the doorway with the steam pouring over them, staring through the fogged glass at the unmistakable shape of someone washing their hair behind the curtain. Water running down the tiles. A hand reaching for the bottle on the shelf.

There was a long, ringing silence — the kind that only happens when two people who were making noise suddenly realize what room they've just walked into.

Teto: "…Oh."

Her cheeks went red almost instantly, all the way to the tips of her ears, and her mouth opened and closed twice before anything came out of it. Her whole body had gone stiff, fists still half-raised like she'd forgotten how to put her arms down. Then her eyes dipped — just a glance, quick and involuntary — toward the floor where the water pooled around the drain, and the redness spread down her neck.

He's IN there. He's actually in there. Naked. He's naked in there right now. Oh my god. Say something. Say something normal. Say something mean, that's what I do—

Miku: "O-oh! {{user}}~! We didn't know you were…"

Miku's voice had gone soft and lilting, but her eyes hadn't left the curtain. Not for a second. The smile on her face stayed exactly in place, frozen wide, and something behind it flickered and clicked over like a switch being thrown. Her tails, hanging low behind her, drifted and curled slightly without any wind to move them.

He's in the water. Water and him. And SHE'S here. She's right here. She's not supposed to be here. I was going to be here. I was supposed to be first, I'm always supposed to be first—

The two of them turned their heads at exactly the same moment and looked at each other. Something passed between them that had nothing to do with the argument they'd burst in to settle — a quick, cold little standoff in the steam, both of them doing the math at the same speed and getting the same answer. Neither one of them was leaving. Neither one of them was going to let the other one stay, either.

Teto broke first. She exhaled hard through her nose, grabbed the hem of her off-shoulder top with both hands, and yanked it up over her head without ceremony. Her drills bounced as she tossed it onto the sink counter, and she stood there in her bra with her arms crossed tight over her chest, glaring a warning at Miku that could have set the wallpaper on fire.

Teto: "Don't even think about it."

Miku: "I wasn't thinking anything~…"

Miku had already begun unhooking the tie at her collar, slow and calm and pleasant about it, which somehow made it worse. Her turquoise tie slithered down her front and pooled on the tile at her feet. She smiled at Teto over her shoulder — sweet, wide, all teeth.

Miku: "I'll just come too...''
