There's enough ingredients in the fridge to make tempura, and so Tsukishima trots to the kitchen with a smile in place and an apron donned. Hachimenroppi watches Tsuki dart back and forth from the fridge and the cabinets to the counter as he pulls out everything he needs. He wants to offer to help, though he's hesitant and nervous. Roppi doesn't regularly cook for himself, the only kitchen appliance he knows his way around is their coffeemaker. If anyone could teach him for certain, it'd be Tsukishima, with his seemingly endless patience and limitless kindness. Roppi's heart beats faster as he vividly imagines donning his own apron and pressing against Tsuki's side in the blond's small kitchenette.

Hachimenroppi stands up stiffly, glaring down at his own feet as his face heats up. He takes a minute to calm and prepare himself, unfortunately waiting a second too long as loud knocks and muffled complaints come from the front door. Roppi's head spins between the blond in the kitchen and the one that disappeared down the hall to dress down for dinner. He shares a quick glance with Tsuki, who fidgets anxiously, before deciding to just answer it for them all himself.

Roppi swings the door open unceremoniously, openly glaring at the blond on the other side. Delic's exaggerated expression of exhaustion and annoyance disappears the instant he recognizes the brunet, a wide, toothy grin replacing it. His eyebrows are wiggling mischievously when Roppi sharply backs away to let him in.

"So, you and sweet, sweet Tsuki-"

"Shut up," Roppi barks, "and get inside before I make you wait for someone else to let you in."

Delic laughs quietly, stepping into the genkan and removing his shoes. "Is that any way to treat your future brother-in-law?"

Roppi scoffs as he turns back to the living room, his eyes rolling like wheels down a steep hill. "Oh please."

"What?!" Delic gasps dramatically, his right hand shooting to his chest as his dessert purchases jostles in his left's grip. "You deflower my innocent Tsuki and then refuse to make him an honest woman?!"

Shizuo reemerges from his bedroom as a loud clatter of utensils falling to the wooden floor comes from the kitchen. His suspicious eyes shoot to the kitchenette, seeing only Tsuki jerkily regather what he's knocked over with a red face, then to the doorway where an equally red-faced Roppi stands with his back to Delic and his horribly amused grin.

"N-Nii-san!" Tsuki tries to admonish, awkwardly stuffing ladles and spatulas into a holding cup.

The other blond turns the corner quickly, excitement keeping him from being still. "So, how was your first time?" Delic's brimmed smile is overeager, though he only halfheartedly expects a legitimate response.

Tsukishima's face blooms rose red, his eyes going as wide as saucer behind his glasses. "H-H-H-"

"Keep your nose out of our relationship," Roppi hisses, shutting the front door a bit too forcefully.

Delic whips his head back to the brunet to squawk, "And let you take advantage of my adorable virgin brother?"

"New rule," Shizuo suddenly announces, reminding the trio of his presence, "no sex in the apartment."

Tsukishima's face sinks into his hands as Delic and Roppi share a look of abject physical pain. "C-Can we have dinner without s-sex talk, please?" He pleas, voice muffled by his fingers.

"Boring," Delic whines as Roppi agrees, "Yes."

The corner of Shizuo's lip quirks fondly and Roppi stiffens instinctively as he approaches them by the kitchenette entryway. Shizuo's arm wraps around Delic's shoulder and brings him closer, his other hand ruffling his newly trapped son's hair. Delic squawks again, his pitch rising and his feet shifting his weight around as he wiggles but doesn't try to escape the weak hold. Roppi's nose wrinkles at the affectionate show, some of the tension the built-up for the eldest Heiwajima leaving his body.

Combing his fingers through the teenager's blond mop for a final time, Shizuo asks "How was school?"

Delic stills and leans his head on his father's shoulder to hum dejectedly. Tsuki pauses his food prep to glance over, passing a worried look to his father. Shizuo picks it up immediately and his hold tightens momentarily.

"Wanna talk about it?"

"No," Delic answers without a beat.

Shizuo sighs. "Alright."

"I'm fine," the shorter blond says after a second of silence.

"Don't lie to me." Shizuo's voice is stern and authoritative to Roppi's ears, but neither of the twins visibly react.

"I'll be fine later," Delic corrects, knocking his head on his father's shoulder.

Shizuo nods, letting the topic die there to move on. "Did you get enough for the whole family?"

Delic's energy returns to him then and he wriggles out from Shizuo's hold like a flailing cat trying to free its head from a jar. He clutches his to-go boxes to his chest childishly, wrapping his long arms around the petite boxes as he openly pouts. "They're mine." He warns as he backs up into the kitchenette to put them away. With his eyes trained elsewhere, Delic bumps into Tsuki in the small kitchenette. The older blond turns around sharply, giving his brother the same treatment as his father.

Shizuo shakes his head fondly, meeting Tsukishima's eyes as Delic deposits his cake in the fridge. "What about you?"

"Oh," Tsuki startles. "Uhm, school was uneventful, there was another akuma though."

"Ah," Shizuo exhales, tilting his head as his eyes dart between the twins. "So all of the events were after school?"

Tsukishima flushes with the light tease. "Papa."

"Does the same go for you, kid?" He asks, turning to Roppi and surprising the brunet by involving him in their family conversation.

"Yes," Roppi answers politely.

Tsuki's face warms again and he chops the next vegetable a bit too cleanly with some poorly managed force. His worries have died down somewhat, no longer on edge with the fear that his boyfriend would be thrown out without a chance. In hindsight, he feels a bit silly worrying so much over his father's reaction. While Tsukishima was dating his enemy's eldest son, that didn't mean that the duo were in cahoots. Though, his father could be reasonably worried about Izaya poking his nose around more often if he ever finds out. Roppi rarely mentioned his father, and usually with a bitter edge to his voice.

Delic's head rotates between his twin and the brunet while he shuts the refrigerator door, a smirk blooming across his face as he settles on Hachimenroppi. "Aren't you going to offer to help?" Roppi's eyes widen as he turns to the blond with an embarrassed flush on display. "Tsuki might be the perfect Nadeshiko, but I'm not seeing a ring on those fingers yet."

"Nii-san," Tsuki yells with a loud chop of his knife mercilessly splitting a carrot. His head furiously spins to his side to glare at his brother despite his cherry red face.

Delic rears back a step, his hands jolting up in mock surrender. He smiles innocently, though he realizes he might've pushed his teasing a bit too far. He can't help how adorable the duo are, they open themselves up for it, really! Delic will happily make the bet that the two marry before he finishes college now.

Out of view of the blond, Roppi's arm raises to smack Delic upside of his head, but a sudden grip to his wrist freezes him still like an icicle pressed to his spine. Stiffly turning his frightened gaze to Heiwajima senior, Roppi's breathing halts under his fierce eyes.

"Playful or not, there's no violence allowed in my home, got it?"

"Yes," the brunet answers quietly and automatically.

Shizuo releases his wrist and Roppi's eyes dart to his skin, marveling at the lack of a mark and pain. The blond's grip had been tight but not too tight, and Roppi's earnestly surprised over the man's control. He only had his father's words on what Heiwajima senior was like and, though he didn't always trust his father's assessment, his head was filled to the brim with numerous warnings and rumors. The man had raised Tsukishima and the young blond is as close to an angel turned mortal that Roppi can name, so something had to be off in his father's stories. Seeing how the trio act so affectionately to one another left a bitter taste in his mouth that Roppi, for once, didn't favor. This household was warm, and not in the claustrophobic sense.

"Hear that," Delic interjects with a jokey tone. "No S&M play allowed, you two."

Another carrot is divided in two with a boisterous snap, the clatter of a knife against the cutting board suspiciously absent. Roppi inhales sharply through his nose to keep himself from huffing over the blond's crassness.

"The same applies in our school, but you can't seem to stop yourself from throwing yourself in front of my brother's feet to be stepped on." Hachimenroppi throws back. He doesn't converse with Hibiya as much as they used to as children, but between the blond's consistent displays of failure and Tsuki's words, he knew how bad Delic had it for his younger brother. Roppi would wonder why if Hibiya actually seemed to enjoy the pursual, but the shorter brunet hadn't shown a single emotion towards Delic beyond disgust in Roppi's presence. Hibiya was practically a Victorian, each and every shameful and shameless flirting attempt immediately dismissed upon being lecherous and uncouth.

Delic stays silent for longer than a beat and Tsukishima's expression of embarrassed anger vanishes as his eyes ignores his dinner prep to watch his sibling's back carefully. Shizuo misses the lull, however Tsuki's open worry snaps his attention to his eldest son.

Delic's lips curl and he smiles mischievously, but even Hachimenroppi can see through the practiced expression and the lack of humor lighting up his eyes. "If only he would," the blond purrs, his eyebrow ticking with the implication. Not wasting another second, Delic quietly excuses himself to the bathroom, lightly bumping into Roppi as he cuts around him hastily.

Things are rapidly clicking together for Shizuo and he sighs elongatedly, his fingers massaging his temples before combing through his hair. Tsuki spares him a glance before the oil in the frying pan bubbles for his attention.

Roppi glances between the duo and down the hallway, the realization of how touchy the subject truly is to Delic sinking in. He doesn't understand the blond's sensitivity and doesn't entirely believe that he has a right to be so, but it won't benefit him to be on rocky ground with Tsuki's twin. He turns and takes a step towards the hallway with the intention of apologizing in mind, but a hand grips his shoulder before his other foot can move forward.

"Leave him alone," Shizuo says authoritatively. "Delic won't admit anything's wrong anyway."

"I'm sorry," Roppi says quietly to the two.

"It's alright, Hachi." Tsuki murmurs while cooking. "We're glad that we know what's wrong now."

Roppi's eyebrow quirks as the blond includes his father. He spares Heiwajima senior a glance and finds his hard stare down the hallway unreadable.

"Will he be alright?" The brunet asks, startling Shizuo in to finally removing his grip on Roppi's shoulder.

"He better be," Tsukishima answers first, his tone finalizing and fingers threatening to snap the chopsticks in his fingers. He stirs the frying prawns a bit more aggressively than necessary, the utensils clinking against the metal pan.

Hachimenroppi blinks owlishly, mildly surprised at the behavior. His boyfriend's temper was more whispered myth than fact until he entered the Heiwajima household and saw it for himself. The comfort of his home and his family eased Tsuki out of shell and Roppi's never been more thrilled in his life or in his pants! Roppi swallows thickly as it strikes him as preposterously attractive. He's never believed his father's expressed motivations behind riling up the Monster of Ikebukuro, but oh god.

"It's fucking genetic." Roppi mumbles aloud to himself, quickly realizing his error as both blonds turn to gaze at him questioningly. His face blooms like a rose that's been set ablaze and he awkwardly shuffles into the kitchenette, hoping the counters will at least hide his shame.

Roppi's plan works, at least until Tsuki peeks over at him, suddenly shy with their closer proximity and his father in the room to witness them together, and chokes back a loud, startled squeak. Shizuo's head snaps to the duo, eyes bouncing between the two with confused suspicion.

"Shut up and tell me where the aprons are!" Roppi barks, keeping his eyes trained on the floor. It's not like his boner wasn't rubbing against Tsuki's leg an hour or so ago! Why the hell does he have to freak out now?

"W-We- I-I-" Tsuki desperately tries as his brain melts inside of his skull and threatens to pour out of his ears.

"Oi," Shizuo interjects, ready to reprimand the brunet for speaking like that to Tsukishima and demanding to know if he treats his son like that all the time.

Tsuki's red face is about to burst, but he quickly forces himself through his stutter. "G-G-Go away, papa!"

"What?" Shizuo shouts indignantly and with open confusion. "What did I do?!"

"Oh my god," a third voice joins in. "You always miss the best parts when you go to piss."

Nothing and no one stops Tsukishima from hurling a wooden spoon at his twin at that moment.
