Call your boyfriend by his full name. If his face looks even a little suspicious—yeah, you’ve got him. :)
Trey Clover / Ace Trappola / Deuce Spade / Jack Howl / Azul Ashengrotto / Jade Leech / Floyd Leech / Jamil Viper / Rook Hunt / Silver / Sebek Zigvolt x Gn!PrefectReader.
As expected of Heartslabyul’s reliable big brother—calm and composed.
He freezes for about two seconds. A little confused, but not completely caught off guard, since he’s pretty sure he hasn’t done anything wrong.
He gently adjusts his glasses and gives you a soft smile, staying polite just in case he did mess up somewhere.
“Hm? I’m listening. What’s wrong?”
When you keep up the serious (clearly fake) expression, hands on your hips, he starts to feel the pressure.
His mind goes into overdrive: Did I forget an anniversary? Your birthday was just last month… the next date anniversary is still three months away, right? Did I overbake the tarts? Was the tea not sweet enough? Was breakfast not to your taste?
You can’t hold it in anymore and burst out laughing.
Only then does he finally let out a quiet sigh of relief, realizing this was just another prank from his beloved:)
He jumps like a cat that’s just seen a cucumber. If he actually were a cat, his fur would be standing straight up.
Instant cold sweat. His limbs stiffen as he forces out an awkward laugh to cover it up.
His brain immediately starts listing every questionable thing he’s ever done—and unfortunately, there’s a lot.
His confidence drops straight to zero. It’s honestly kind of hilarious.
No one flinches harder than Ace. Before you can even ask a follow-up question, he’s already confessing—finger pointing straight at Grim.
“I didn’t do anything! The jam you hid in the cupboard? Grim ate it! The bowl you like that broke? Grim did it! Your missing workbook? Grim took it!”
“WHEN DID I EVER DO THAT?!” Grim explodes nearby.
What started as a harmless tease turns into Ace confessing his entire life story of crimes, past and present:)
“Ohhh? So that’s how it is, huh… A-C-E T-R-A-P-P-O-L-A!!! DON’T YOU DARE RUN FROM ME!!!>:(”
He definitely flinches. His face goes pale almost instantly, even though he hasn’t figured out what he did wrong yet.
“W-What? Why are you suddenly calling my full name??”
The model student experience™. He genuinely starts reflecting on himself, desperately searching for a mistake—but the more he thinks, the more confused he gets.
He tries to appease you first, hoping to calm things down while his brain continues to dig through his memories.
Still nothing. Poor guy is on the verge of panicking:)
“P-Please calm down first—don’t be mad at me—”
He starts self-reflecting with extreme sincerity, despite having no idea what crime he’s being accused of.
He holds your hand or gently pats your shoulder, apologizing with such genuine remorse it almost feels real.
Please don’t tease him like this too often—Deuce might actually get a heart attack:")
His wolf ears snap upright before immediately drooping down. His expression tightens, and he instinctively turns his head away to avoid your gaze.
His tail puffs up slightly as he scratches at his head and ear, trying to remember if he did something wrong.
In reality? The good wolf hasn’t done anything.
Still, he looks at you—hands on hips, clearly displeased—with sincere guilt, like a big dog being scolded by its owner.
“It sounds like I committed some kind of serious mistake… I-I’m sorry if I upset you somehow…”
He looks so flustered and earnest that you can’t help but explain and reassure him.
He turns bright red the moment he realizes it was just a joke:)
Defense mode activates immediately. His teacup freezes midair for a second before he carefully places it back onto the saucer.
A professional, businesslike smile curves onto his lips.
“Is there something wrong, my dear prefect?”
He adjusts his glasses. Calm on the outside—but there’s definitely a flicker of unease within.
His mind starts calculating possibilities and damage control strategies, even though he hasn’t pinpointed the issue yet.
Wait… did you find out he added a 5% interest fee to Ramshackle’s invoice???
He straightens his tie, his voice wavering just slightly as he maintains his composure.
“Is there something you’re dissatisfied with? We can sit down and discuss this calmly and rationally, you know…”
He doesn’t confess outright. Instead, he pulls out a chair for you, pours tea, and slides the pastries closer.
When he realizes this is just playful teasing, he finally exhales in relief:)
Far more perceptive. His eyes narrow slightly, smile still polite—but sharper now.
“Do you have a request, my pearl?”
He isn’t startled at all. He immediately sees through your fake seriousness and knows it’s a joke.
“Ah… so you’ve discovered it already.”
He lets out an exaggerated, dramatic sigh, putting on a look of disappointment and guilt that makes you raise an eyebrow.
“Such a grave sin… it’s only natural that you’d be angry.”
“What did you even do, Jade?”
“Surely you know best, my pearl? ^^”
You’ve been manipulated. Now you’re the one chasing after him, demanding answers.
“Jade! What did you DO??”
He refuses to say anything, just smiling innocently while enjoying your confusion—trying very hard not to laugh.
He pouts immediately, mood shifting into full-on displeasure.
He doesn’t flinch—but he really doesn’t like being called by his full name. It feels distant.
He stalks toward you with an intimidating expression, his tall frame radiating pressure.
In reality, he just scoops you up into his arms, squeezing you tightly and burying his face against your neck.
He’s pouting. Straight-up sulking.
“What’s with that, Little Shrimpy~? Calling me that sounds way too long and distant! Call me ‘Floyd’—say it nice and sweet! Or I’ll squeeze you until you forget my last name entirely, kay~?”
He does briefly scan his memory to see if he broke something of yours (actually he definitely did).
There are plenty of crimes—but either he doesn’t remember, or he remembers and just doesn’t care to admit it:)
Either way, this tactic works every single time. You drop your guard immediately when faced with his clingy antics!
His pupils contract. He clears his throat, regaining control of his expression almost instantly—but his mind is already racing through worst-case scenarios.
Ever cautious, he keeps a mental list of possible “offenses” (all minor, really).
He immediately switches to S-rank crisis management mode.
Probably the most paranoid person in all of NRC.
“Prefect, please calm down. I’m listening. Did Kalim cause trouble for you again? Or was there something wrong with dinner? If I did anything to upset you… then I apologize.”
He has no idea what he did wrong—but apologizing comes first.
When he realizes this is just another prank, he lets out a long sigh.
The stress nearly gives him a headache, so he flicks your forehead in retaliation. Honestly, one Kalim is already more than enough for him:)
“Don’t pull stunts like this again…”
You nod obediently, silently promising to absolutely do it again>:)
Instead of being shaken, the wandering hunter looks thrilled.
“Beauté! Such a commanding sound! When you speak my name like that, it feels like a declaration of eternal love! Say it again, mon amour!”
Rook doesn’t feel fear—only romance.
He kisses the back of your hand with elegant flair, nearly making you forget you were teasing him in the first place.
You assume this trick doesn’t work on him at all.
But behind those sharp hunter’s eyes, countless thoughts are already swirling. He knew you were joking from the very first second—his observation skills saw right through you.
Still, he chose to play along and savor the moment with you.
After all, he successfully distracted you— so no need to overthink things now. ^^
Poor thing. He was half-asleep (as usual) when you suddenly called his name, startling him into bumping his head against the stone pillar he was leaning on.
He’s fully awake now, looking adorably dazed.
“Ah… is that you, Prefect? Did something happen?”
This prank doesn’t really work on him.
After all, you usually just call him “Silver”—it’s not like he has a long full name anyway.
He’s simply confused, completely unaware that being called like that could imply wrongdoing.
Those clear blue eyes are utterly innocent.
Conclusion: he is blameless, and you really shouldn’t bully him.
“It’s nothing. I just wanted to say you look really handsome today. Go back to sleep, Silver.”
As expected—extremely loud.
You were prepared this time and covered your ears in advance.
He shouts at full volume (knew it).
“HUMAN! HOW DARE YOU CALL ME BY MY FULL NAME?! SUCH DISRESPECT—”
“…But, um… it doesn’t sound bad /clear throat/ What do you want from me?”
He has absolutely no idea that being called like that might mean he’s in trouble.
He crosses his arms, brows furrowed—but he’s clearly delighted by the “honor.”
This was not a calculated move on your part.
Seeing him this happy, you don’t have the heart—or courage—to tell him it was just a prank. Just value your eardrums too much.
“…I just wanted to say you look really handsome today, Sebek.”
“OF COURSE! I AM THE LOYAL RETAINER OF MALLEUS-SAMA—"
Predictably, he launches straight into another monologue about Malleus.
Still, he’s adorable—so you decide to sit and listen a little longer<3
