OMG yesss

You barely manage to get out the words, “Hey, Mitsuri, wanna do the pit bull terrier trend with me?” before she gasps so hard you think she might faint.

“YES!! Oh my goodness, I was hoping you’d ask!”

Within seconds, she’s grabbing her phone, fixing her hair, and asking if you want to match outfits. Of course, you do. She’s glowing with excitement, humming to herself as she helps you pick your top and smooths your hair with soft fingers.

When you finally record, Mitsuri gives everything she’s got: playful growls, perfect poses, over-the-top expressions that make you laugh halfway through. You try to stay serious, but she’s just too cute.

You end up posting the take where she bursts out giggling and you follow, both of you collapsing on the couch. Later, she cuddles up next to you, scrolling through the comments.

“They all said we’re adorable together,” she says proudly. “They’re right,” you reply, and she hides her face against your shoulder, blushing like she’s hearing it for the first time.

You: “Okay, listen. It’s this trend—” Shinobu: raises one brow “...trend?”

You show her the TikTok, and she watches the entire thing in complete silence, then gives you that polite, unnerving little smile.

“So you want me to do that?” “Yeah! It’s just for fun—” “Mmm. Fun.”

She walks away. You think that’s a no. So later, you record it alone, giving your best energy, and post it.

When Shinobu sees it, she doesn’t say a word at first. You find her at the counter, sipping her tea, phone in hand, that same quiet smile plastered on her face.

“So,” she says sweetly, “that’s what you were doing instead of washing the dishes?” You freeze. “...Maybe?” She leans in close, voice soft but lethal. “You looked very cute. But I do hope you enjoyed your fifteen minutes of fame, since you’ll be on cleaning duty for the next week.”

You swear you see her trying not to laugh when she walks away.

You bring it up while he’s half-asleep on the couch.

“Wanna do the pit bull terrier trend with me?” “The what?” You explain it quickly, showing him an example. His expression goes from bored to disgusted. “Hell no.” “Fine. I’ll do it alone.”

You do, and it turns out great. You post it, not thinking much of it, until later, when you hear a muffled choke from the other room. You peek in. Sanemi’s staring at your video, jaw tight, ears red.

“Why the hell do you look so... like that, doing it?” “Like what?” “Like that! All… whatever!”

He shuts off his phone and stomps out, muttering curses, but later you catch him scrolling through the comments again, blushing so hard it’s ridiculous.

You explain the trend carefully, expecting him to laugh it off, but he listens seriously, nodding as though it’s a philosophical matter.

“It is… a type of dance, perhaps?” You blink. “...Yeah, let’s go with that.”

To your surprise, he agrees to do it, mostly because you look so excited. He’s gentle about it, helping you set up the camera, adjusting the lighting (“Symmetry is important,” he says).

When you film, his presence is intense, even doing something silly, there’s this calm power to him that makes the video oddly mesmerizing. You try not to laugh but you’re also kind of in awe.

The clip goes viral overnight. People comment things like: “Gyomei just redefined the trend.” and “Why do I feel blessed watching this?”

(Blessss 🙏🙏🙏)

When you "show" him, he smiles softly.

“I’m glad people enjoyed our moment together.” And you swear, no one’s ever made something this ridiculous feel so interesting.

You ask him while he’s doing laundry.

“Giyu, can you do a trend with me?” “What kind?” You show him one example. He just stares. “...Like pretending to be what?” “It’s not pretending, it’s a vibe.” He sighs. Long, resigned. “Fine. Just once.”

You record it, and he’s so stiff it’s adorable. He doesn’t blink, doesn’t smirk, just stares dead into the camera... somehow it works. You post it anyway, and when you check later, the comments are insane. “Why does he look like a runway model?” “He’s accidentally the hottest one doing it.”

He pretends not to care, but you catch him scrolling through the comments that night.

“They liked it,” you whisper. “They’re wrong,” he mutters, face hidden in your pillow. You grin. “You liked it, though.”

Before you even ask, he’s seen it.

“You want to do the pit bull terrier trend?” he says with that smug grin. “Of course you do. You have taste.”

He’s already fixing his hair, choosing which chains sparkle best under the lights, and offering to “direct” it. You end up doing the trend together, dramatic lighting, slow motion, perfect angles, Tengen looks like he’s filming a music video.

You’re trying not to laugh the whole time, but when you post it, the internet loses it. “They understood the assignment.” “This is the only acceptable couple version.”

He reposts it immediately with a caption:

“Beauty. Power. Flamboyance. You’re welcome.”

Then later, he winks at you.

“We might have to do a part two, my love.” You: “You just want another excuse to show off.” “Exactly.”

You: “Wanna do the pit bull terrier trend with me?”

“No.” You: “...You don’t even know what it is.” “Don’t need to.”

You sigh and do it anyway. When you post it, he’s quiet for about two hours, then storms into the room, phone in hand.

“What is this?” “A video?” “You were making that face on purpose.” “It’s literally part of the trend.” He narrows his eyes. “Delete it.” You smirk. “No.”

He sulks, sitting next to you with his arms crossed. Later, you find him watching it again, eyes slightly narrowed but his cheeks red.

“You looked… fine,” he admits quietly. You grin. “You mean hot?” He looks away fast. “Shut up.”

When you ask, his face lights up like he just won the lottery.

“A trend, you say?! Great! Let us do it together, Y/N!”

He takes it very seriously, practicing expressions in the mirror, hyping himself up out loud. You’re already crying laughing before recording even starts. When you finally hit record, he gives it everything: fiery eyes, booming voice, perfect timing. You try to keep your composure, but he’s so dramatic you end up laughing halfway through.

You decide to post that take, both of you grinning like idiots. His caption reads:

“A splendid time shared with my beloved one!! 🔥”

The comments are all “HE’S TOO PURE” and “Why did I smile the whole time?” He shows them to you proudly, chest puffed out.

“They enjoyed it!” “Of course they did,” you say. “You’re impossible not to love.” He beams, as if that’s the greatest praise he’s ever received.

(Older in this AU — early 20s.)

He’s sitting on the edge of your bed, scrolling through art references, when you ask, “Wanna do the pit bull terrier trend with me?”

“What’s that?” You show him one, and he tilts his head. “So… like an act or something?” “Not act, Muichiro. It’s more… attitude.”

He blinks slowly, clearly not getting it, but eventually shrugs.

“If it makes you happy.”

When you record, he’s surprisingly calm and confident. He gets it somehow, the timing, the gaze. You’re the one thrown off this time, nearly forgetting your cue.

You post it, and it explodes. Comments: “HE DIDN’T HAVE TO GO THAT HARD.” and “He’s the reason this trend exists now.”

When you show him, he’s indifferent.

“People liked it?” “They loved it.” He nods, eyes soft. “Good. You looked really pretty in it.” You blink. “...You just said that so casually.” “Should I not tell the truth?”

And just like that, he leaves you speechless.

Extra:

You’re lounging in the living room, scrolling on your phone when the sound comes on your FYP for the tenth time that day. You can already picture it: that slow zoom, that stare, the intensity. Tengen walks by shirtless, towel around his neck, and you don’t even think

“Babe. We have to do this trend.”

He stops, smirks, and leans against the doorframe.

“Which one?” “The pit bull terrier one.” “Ah,” he grins, teeth flashing. “Flamboyant. I like it already.”

Of course, once you say the word trend, the other three are listening. Hina pokes her head out from the kitchen, elegant but curious.

“Wait, are we doing another one of those couple videos?” Makio’s already on the couch, stretching. “If it’s something stupid again, I’m in.” Suma, bouncing on her toes, squeals, “I love that! Let’s do it!!”

You try to explain the trend, but Tengen’s already scrolling through examples like a director preparing for a shoot. He sets the lighting, checks everyone’s outfits, makes sure no one looks “mediocre.”

“We must deliver beauty,” he declares, adjusting the camera. “And bite.”

Hinatsuru’s effortlessly sultry, Makio’s chaotic and cool, Suma’s trying to look intimidating but keeps giggling halfway through, and Tengen, well, Tengen looks like he was born for this. You record a few takes, and the result is absurdly hot and hilariously messy.

After the last take, everyone collapses in laughter. Suma clings to your arm. “I think I was too loud…” Makio smirks. “Yeah, the neighbors probably think we started a cult.” Hinatsuru just smiles softly, smoothing her hair. “At least we looked good doing it.”

Tengen checks the video and nods, utterly pleased.

“Perfection. We’ll post it with a caption: ‘A pack too flamboyant for your screen.’” You groan. “Please no.” He kisses your cheek. “Too late. Already typed.”

When it goes up, the comments explode. “No way they’re real.” “They understood the assignment AND rewrote it.” “Suma’s laugh alone cured my depression.” “Their house is the definition of chaos and sexiness.”

Hours later, you’re all curled up together on the couch, scrolling through the notifications. Makio’s teasing Tengen about the way he bit his lip too hard in one take. Suma’s reading comments out loud in dramatic voices. Hinatsuru’s quietly liking every one that calls you all “unfairly attractive.”

You nudge Tengen’s shoulder.

“You realize we can’t top this, right?” He smirks without missing a beat. “Challenge accepted.”
