Chapter Text
The weekend began quietly.
There were no reservations, no itineraries, and no demanding workload. Forty-eight hours lay before Diesel like a blank sheet of paper, and for once, he didn't feel the urge to fill it with billable hours or networking.
Diesel showed up at Day’s house on Saturday morning before the city’s heat had fully settled into the pavement. He was early because he had spent the night realising that his luxury was no longer a comfort. He found himself craving the chaotic and deeply human hum of the small house in the residential lane.
Day opened the door, his hair a messy, sleep-tousled crown and his eyes slightly dazed behind his glasses. He was wearing a faded t-shirt and a pair of soft pyjama pants. He clearly hadn't expected Diesel for at least another two hours.
“You’re here,” Day said, blinking against the morning light, his voice still thick with sleep.
Diesel held up a brown paper bag that was warm to the touch and smelled of fresh flour, yeast, and sweet butter. “Breakfast. Pain au chocolat and the specific almond croissants you liked from the bakery near my penthouse. And I’m early. If you want to go back to bed for an hour, I can keep myself occupied. I’ve brought a brief I need to review, or I can just watch you sleep, non creepily, of course”
Day smiled. It was a smile of genuine welcome, “No. Come in. I have been awake for 20 minutes, the kitchen is a work in progress—Ozone had a bit of a spill with his juice earlier—but the coffee is fresh, and the company is welcome.”
Ozone was already awake. He was sitting cross-legged on the living room floor, his back to the door, surrounded by the skeletal remains of a new 2,000-piece puzzle. A documentary about the Voyager probes played at a low volume on the TV.
“Diesel,” Ozone said without looking up.
Diesel nodded. “Morning, P’Ozone. Any progress on the nebula?”
“The nebula is finished. I completed it last night. This is the lunar surface—specifically, the Mare Tranquillitatis.” Ozone replied.
It felt normal. That was the word that kept echoing in Diesel’s mind as they ate breakfast at the small, scratched kitchen table. There was no pressure to fill the silence. It was simple. It was easy.
And then the day truly began.
Routine, Diesel realised quickly, was not just a preference for Ozone; it was the heartbeat of the house. Meals happened at specific intervals. Activities were preceded by verbal countdowns.
Day moved through it with what looked, at first glance, like muscle memory. But as the hours ticked by, Diesel began to see the effort beneath the ease.
“Time to switch, P’Ozone,” Day said gently around eleven o’clock. “We need to do the laundry and then have a blended fruit snack. You’ve been on the floor for three hours. Your joints need to move.”
Ozone didn't move. His focus remained locked on a piece of the Sea of Tranquillity. “No. The crater isn't finished.”
Day didn't sigh. He didn't get frustrated or raise his voice. He simply leaned against the doorframe and waited. He didn't push or repeat the command immediately. He allowed the information to settle, giving Ozone the time he needed to process the interruption.
“Five more minutes,” Day said instead.
Ozone nodded once.
Five minutes passed. The clock clicked over. Ozone didn't move.
Day moved closer this time, crouching slightly to bring himself to Ozone’s eye level, but maintaining enough distance to respect his personal space. “The timer is done, P’Ozone. We agreed on five minutes.”
This time, there was resistance. A sharp, frustrated sound left Ozone’s throat—a low growl of overstimulation—and his hands tightened around the puzzle piece until his knuckles turned white. “It’s not finished. I can’t leave it unfinished. It’s illogical.”
Day stayed calm. He didn't use authority; he used logic and reassurance. He explained the schedule again, redirected Ozone’s focus to the afternoon's rewards, and slowly, he guided Ozone toward the kitchen, a way of absorbing Ozone’s anxiety so that Ozone didn't have to drown in it. Day was the shock absorber, taking the impact of the world so his brother didn't have to.
It worked. Eventually. But Diesel noticed the shift afterwards. As Ozone sat at the table with his snack, Day walked back to the kitchen counter to refill a water glass. He took a long, slow breath and leaned his weight against the wood for a heartbeat, his forehead touching the cool surface of a cabinet.
It was a small moment—almost invisible—but to Diesel, it was deafening. Diesel realised that Day’s strength wasn't an inherent trait; it was a daily choice that cost him everything he had.
By midday, Diesel stopped being a spectator. He realised that the easy atmosphere he had enjoyed earlier was a direct result of Day’s constant, invisible work. They were the result of a thousand tiny, unthanked decisions.
“Lunch?” Diesel asked once, seeing Day start to reach for the fridge with a slight tremor of fatigue in his fingers.
Day blinked, looking surprised by the interruption, as if he had forgotten that another adult was in the room capable of functioning. “I usually handle the sandwiches. Ozone likes the crusts removed in a very specific geometric pattern—triangles only, no overlapping edges. It's a texture thing.”
“I think I can follow a set of instructions on bread-cutting.” Diesel stepped into the kitchen, gently but firmly nudging Day aside. “Go sit. Or better yet, go lie down for twenty minutes. I’ve got the kitchen.”
Day hesitated, a flicker of guilt crossing his face—the guilt of a caretaker who feels like they aren't allowed to rest, as if the world will stop spinning if they take a breath. Then, he looked at Diesel, “Okay. Triangles, Diesel. No crusts. If you mess up the symmetry, he’ll tell you. Loudly.”
“I’m prepared for the critique,” Diesel said, rolling up his sleeves.
The afternoon was quieter. Ozone settled into his space book, his mind calmed by the lunch Diesel had prepared, which Ozone had indeed inspected for three full minutes before taking a bite. Day finally sat down on the sofa, his posture collapsing into the cushions. Diesel watched him from the armchair across the room.
“You’re tired,” Diesel said softly.
Day shook his head automatically. “I’m fine. Just the humidity. It’s been a long week at the department.”
Diesel didn't argue. He knew a defensive wall when he saw one. He just noted the exhaustion and made a mental list of all the things Day was doing that no one noticed. The way he checked the water filter. The way he adjusted the curtains. The way he anticipated a question before it was even asked.
Sunday followed the same pattern. It was "Adventure Sunday," a day Day usually dedicated to taking Ozone somewhere outside his comfort zone to maintain his social adaptability. It was a necessary part of Ozone's growth, but it was also a day of extreme tension for the caretaker.
“We’re going to the aquarium today,” Day announced at breakfast, his voice cheerful but his eyes already calculating the logistics.
Day packed a go-bag, noise-cancelling headphones, a specific brand of unsweetened juice, a backup t-shirt in case of accidents, and a schedule of the aquarium’s feeding times. He checked the bag three times, a nervous tic Diesel hadn't seen before.
“The aquarium is high-sensory,” Day explained to Diesel as they headed to the car. “It’s a lot of echoing noise, flashing blue lights, and unpredictable crowds. The humidity inside can be a trigger, and the smell of the salt water can be overwhelming. It takes a lot out of him.”
When they arrived at the aquarium, the shift in atmosphere was immediate. Diesel saw Ozone’s posture stiffen, his hands beginning to flutter near his sides—a sign of rising anxiety.
Day moved in instantly. He reached out and adjusted Ozone’s headphones, stepping into his brother’s line of sight to provide a familiar anchor. “Deep breaths, P’Ozone. Ten minutes to the entrance. Focus on the jellyfish. Think about the bioluminescence.”
Diesel watched Day the entire time. Day was a master of redirection. When a group of teenagers laughed too loudly near the ray tank, Day would immediately point out a specific detail on a nearby coral reef to keep Ozone’s focus internal. He was constantly checking Ozone’s face, reading the micro-expressions of stress, and calculating whether they needed to find a quiet zone. Day was effectively living two lives at once, his own and the one he was managing for his brother.
“He’s doing well today,” Day whispered to Diesel as they stood before the massive, glowing wall of the jellyfish exhibit.
“You’re the reason he’s doing well,” Diesel replied. “You’re acting like a human firewall, Day. Every time a noise or a person threatens to get too close, you intercept it before it even hits him. You're the one taking the hits, so he doesn't have to.”
Day leaned his head. “If I don't, the crash is harder for him later. It’s easier to prevent the flood than to clean up the wreckage. But sometimes... sometimes I forget what it's like to just look at the fish without thinking about the exit strategy.”
As they returned home, Ozone retreated immediately to his room, his social and sensory batteries completely depleted, yet appearing content.
Day didn't even make it to the kitchen. He simply collapsed back against the couch, his head falling onto the fabric with a dull thud. He looked hollowed out.
Diesel sat beside him, close enough that their shoulders touched. He reached out, taking Day’s hand and lacing their fingers together. Day’s palm was warm, but his grip was loose, as if even the act of holding on was an effort his body was barely managing.
“You do this every day,” Diesel said.
Day nodded, his eyes fixed on the ceiling. “It’s normal. It’s our life. It’s what I do. It's the only way I know how to be a brother.”
Diesel turned to look at him, “That doesn’t mean it’s easy, Day. You’re holding up the entire sky for this family. I see the invisible strings now, Day. You're drowning in the deep end, and you're trying to act like you're just swimming.”
Day smiled faintly, finally looking over at Diesel. The exhaustion in his eyes was naked now, “I’m used to the weight. I’ve been building the muscles for it for a long time. You get stronger when you have no choice. But it is... it is heavy, sometimes.”
“I don’t think you should have to do it alone,” Diesel said, his fingers tightening around Day’s.
Day squeezed back, his expression softening into something grateful and slightly overwhelmed. “I’m not alone. I have Night and Dream. And most importantly, I have you. That’s more than I ever expected. I didn't think there was room for anyone else in this routine.”
The words settled deep in Diesel’s chest, but they didn’t change what he had seen. They didn’t change the reality. Day was strong, yes, but he was human, and he was tired. He was so incredibly tired of being the only one who remembered where the water filter was or where the ear defenders were kept. He was tired of being the firewall.
Diesel exhaled slowly, a quiet, deliberate plan forming in his mind.
He would make this easier. Not by taking over, because Day needed his autonomy as much as Ozone needed his routine. Not by replacing the labour with money alone, but by being the presence that shared it. By being the one who remembered the water, the one who handled the bread-cutting. He would be the support for the support system.
“I’m staying on Tuesday,” Diesel said suddenly.
Day blinked, confused, “Tuesday? But you have court in the morning. You have your own life, Diesel.”
“I’ll drive from here,” Diesel said, “ I am going to help you out around the house. It’s non-negotiable. You can't be the only one holding up the sky.”
Day laughed, that ended in a soft, shaky sigh. He leaned his head onto Diesel’s shoulder, finally letting his full weight drop, trusting the man beside him to hold it.
Diesel held him there, staring at the empty living room. He was going to build a home that didn't just house Day, but actually held him.
The boundaries between "mine" and "ours" began to blur until the distinction felt irrelevant.
It started with a toothbrush. Then came the work-from-home station. Diesel’s heavy, leather-bound legal pads and gold-nibbed fountain pens began to claim permanent territory on Day’s wooden study table next to stacks of film theory journals, ungraded student essays.
In return, the penthouse began to grow soft at the edges, its sharp lines rounded out by the presence of another soul. Day’s oversized, faded cotton hoodies now hung in Diesel’s walk-in closet. A stray pair of Day’s reading glasses once spent three days on Diesel’s marble nightstand. Every time Diesel saw them, he felt a strange reminder that the cold tower now had a heartbeat.
The shift was most apparent on a Saturday afternoon, when the air in Day’s house was thick with the scent of garlic, bruised basil, and the spicy promise of a big family lunch. Diesel had arrived early to help with the prep, though his definition of helping usually involved more distraction than actual labour.
Day was at the stove, his back to the room as he stirred a pot of green curry, the coconut milk bubbling. Diesel was supposed to be chopping bird’s-eye chillies, but the knife had been abandoned on the cutting board minutes ago. He was currently crowded into Day’s personal space, his lean frame acting as a second skin against Day’s back, pinning him gently against the edge of the counter.
Diesel’s arms were wrapped firmly around Day’s waist, his hands splayed low across Day's stomach, pulling him back against his chest. He buried his face in the crook of Day’s neck, breathing in the intoxicating mix of galangal and the clean, warm scent of Day’s soap.
“Diesel,” Day murmured, a shaky laugh catching in his throat as Diesel’s lips began to trace the sensitive line of his pulse point. “The curry... it needs constant movement, or the milk will separate.”
“Just simmer the curry or turn the stove off ”, Diesel rasped, his voice a low vibration that Day felt deep in his spine.
He nipped lightly at the tendon of Day's neck, eliciting a low, ragged hum from the professor. Day turned in the circle of Diesel’s arms, his wooden spoon dripping a green droplet onto the floor, unheeded.
Diesel didn't give him a chance to argue about kitchen safety. He captured Day’s lips in a kiss that was deep and possessive. It was a slow, tongue-tangled exploration that tasted of the afternoon heat and the absolute, terrifying certainty of belonging. Day’s hands slid lower, his fingers digging into the denim of Diesel’s jeans to hoist him slightly higher against the counter, pressing their hips together until the friction was the only thing Diesel could process. Diesel’s hands came up to tangle in the dark, soft hair at the back of Day’s head, pulling him closer, deeper, as the sound of their shared, frantic breathing began to drown out the whistle of the kettle.
“It is bad manners to boink in the kitchen.”
The voice was flat and perfectly audible over the bubbling curry.
Diesel and Day jumped apart as if they’d been hit by a live wire. Ozone was standing in the doorway, his arms crossed, his eyes narrow behind his spectacles.
“P’Ozone,” Day stammered, his face turning a shade of red that rivalled the bird’s-eye chillies on the counter. He frantically wiped the counter with a towel that was already clean, his glasses slightly askew from the intensity of the kiss. “We weren't... we were just... tasting the food. Checking the seasoning.”
“Boinking,” Ozone repeated, “It is a high-energy activity that involves a high degree of fluid exchange. The kitchen is for food preparation. Cross-contamination is a risk when the Chef is preoccupied with pelvic proximity.”
Diesel cleared his throat, his ears burning. He adjusted his shirt, trying to summon even a fraction of his usual dignity. “We weren't boinking, P’Ozone. It was just a kiss. A greeting.”
Ozone adjusted his own glasses, his gaze unblinking and terrifyingly observant. “The respiratory rate and the muscular tension suggest otherwise. Furthermore,” he continued, stepping into the kitchen to check the microwave timer with a dismissive shrug, “you are both very loud while mating at night. The sound travels through the drywall with significant clarity. It disrupts the silence required for my star-mapping and my sleep schedule”
The silence that followed was absolute. Diesel felt like he had been served a subpoena for his own dignity in front of a full gallery. Day looked like he wanted to dissolve into the floorboards and relocate to another province under an assumed name.
“Mating?” Day squeaked, his voice hitting a register Diesel had never heard before.
“The biological term for your nocturnal activities,” Ozone said, opening the fridge to retrieve a juice box. “I have begun wearing my noise-cancelling headphones to bed. It is a functional solution to your mating sound, but I felt you should be aware”
He turned and walked out of the kitchen without another word, leaving the two men standing in a vacuum of soul-crushing embarrassment.
“I am going to die,” Day whispered, covering his face with his hands. “I am going to literally expire right here in front of the green curry. Tell my students I loved them.”
Diesel let out a shaky, half-strangled laugh, leaning his forehead against Day’s chest.
An hour later, the dining table was crowded. Night and Dream had arrived with a crate of beer and a bag of mangosteen. Though they had seen Diesel in passing before—quick, awkward waves from the porch when they’d come to pick up Ozone for planetarium shifts or weekend outings—this was the first time they were actually sitting down to a meal with him.
Diesel sat next to Day, their knees touching under the table. He was acutely aware that these two people weren't just friends; they were the family Day had chosen during his hardest years, the ones who had seen him through the fallout of his parents' death and the early, terrifying days of caring for Ozone alone. Their approval meant everything.
“So, Diesel,” Dream noted, propping her chin on her hand as she studied him over a glass of iced tea. “You look a lot different than you did when we saw you getting out of that Bentley last month. ”
“I have been told I have softened around the edges”, Diesel replied, offering a genuine smile that actually reached his eyes.
“It’s the company,” Night joked, nudging Day with his elbow. “Our professor here finally found someone. Although technically, we should be the ones interviewing you. Day is notoriously bad at letting people in. He usually has more walls than a high-security prison.”
Day groaned, serving a massive heap of rice onto Night’s plate to shut him up. “I am right here. Please don't talk about me like I’m a research subject in a study. I’m trying to feed you.”
The mood was light, the food was excellent, and for a few minutes, Diesel felt he was passing the test. He enjoyed the easy, loud energy of the squad—the way they talked over each other, the way Night teased Dream about her latest surgical case, and the way the air felt like it was composed of more than just oxygen.
Until Ozone, who had been quietly and meticulously deshelling a prawn, decided to talk.
“Day and Diesel were boinking in the kitchen before you arrived,” Ozone announced to the table, his tone as flat and matter-of-fact as if he were announcing the weather.
Night choked on his beer, a spray of foam hitting the tablecloth. Dream’s eyes went as wide as saucers, her fork clattering against her plate as she stared at Day.
“Ozone!” Day shouted, his ears practically glowing in the midday light. “I told you, it was just a kiss! We were—we were talking about the grocery list”
“The grocery list does not require that much tongue,” Ozone countered, not looking up from his prawn. “The interaction was clearly recreational. And they were mating very loudly on Tuesday night. I had to wear my headphones because I could not sleep, and then I felt so sleepy in the morning”
The table erupted.
Night let out a roar of laughter that shook the plates, “Very loud? DayDiesel, you animals!”
Dream was cackling, her hands over her eyes, “ Oh my god, Day, I didn't think you had it in you! No wonder you were so tired when we met for lunch on Wednesday! You were suffering from high-intensity mating fatigue!”
“It wasn't—we didn't—” Day scrambled for words, his hands flying through the air in a desperate, futile attempt to catch the conversation and reel it back in. “It was nothing! Ozone is... he’s exaggerating”
“I do not exaggerate”, Ozone stated firmly, finally popping the prawn into his mouth and chewing. “ I can even tell what you were talking about while mating”
Diesel realised that he could not sit through P’Ozone spelling out what he had moaned. He looked at Night’s howling laughter and Dream’s delighted grin.
He reached over and took Day’s hand, lacing their fingers together on the tabletop for everyone to see. “He’s right,” Diesel said, his voice steady even as his face burned with a heat. “ I’m very fond of Day, and I’m apparently not very quiet about it. I apologise for the disturbance, P’Ozone. I'll have our rooms soundproofed.”
Night’s laughter softened into a wide, impressed grin. “I like him. I officially like the billionaire. He’s got balls to admit to high-intensity mating in front of high school best friends. Welcome to the circus, Diesel.”
“He’s got something, clearly,” Dream teased, winking at Day. “And if it’s enough to make you forget your own no public displays rule in the kitchen, then he’s definitely the one for you.”
Day hid his face against Diesel’s shoulder, a muffled groan escaping him, but he didn't pull his hand away. “I hate all of you. Every single one of you. I’m moving to a monastery.”
“No, you don't,” Diesel whispered into his hair, his voice low and private amidst the teasing.
Day nudged him sharply in the ribs, but he didn't pull away. In fact, he leaned closer, seeking the heat of the man who had turned his quiet life into something loud, messy, and infinitely better.
As the lunch continued, the teasing turned into a real conversation. Diesel realised that while his name was on the deed of a million-baht penthouse, this was the first time he had ever sat at a table where he didn't have to watch his back or calculate his words. He looked at Ozone, who was now explaining something to a captive Night. He looked at Dream, who was arguing with Day. And then he looked at Day—his boyfriend, the man whom he had started to love like breathing.
He was home.
