Chapter Text
“Coffee, anyone?”
You maneuver throughout the space station in its zero-gravity, with your hands grasping hold bars to propel you forward. The call for coffee has you salivating, and you eagerly accept the plastic pouch of steamy java.
A moan escapes after the first hit of caffeine. “If we didn’t have this on board, I would have gone crazy months ago.”
A warm laugh hits behind you. “You’re already crazy, pipsqueak.”
Caleb floats by you and ruffles your hair before getting his own coffee.
“Well, you’re not wrong.” You quip back with a smile, putting the straw back in your mouth.
Murphy squeezes herself into the compact gathering area. “Alright, how about some of you go somewhere else so the rest of us can get breakfast.”
You smile at your best friend, “Murph,” before launching yourself to another corridor. You make a turn and find yourself inside the Cupola.
Planet Earth still looks breathtaking like this. The curvature of the planet, with its distinct blue hue and wispy ivory white clouds, makes you pause every time you take it in. It’s your home in this tiny piece of the universe, despite pushing yourselves out further in pursuit of exploring the frontiers of space.
“I can always count on you taking your coffee in here.” You turn to the side as Caleb joins you for the view.
Bathed in the cool, ambient glow of Earth, there is a comfortable, easy warmth to the line of his jaw and slight, resting curve of his mouth that speaks of shared secrets and inside jokes. His dark brown hair is floating in soft, unruly tufts that expose his forehead, yet it still gives him that persistent, familiar boyish charm you associate with him.
When he turns his head, the station’s solar array casts a shadow that cuts across his face, but the planet’s reflection catches his purple eyes, turning the deep violet into something luminous. They are entirely focused on you, holding a striking depth that has absolutely nothing to do with the vast vacuum of space outside the glass.
His lingering gaze carries a quiet, bittersweet weight.
With a sigh, you look back out the window. “It never gets old seeing her like this.”
Caleb smiles. “Remember when we were kids, and we would lie on the trampoline outside to stargaze?”
You chuckle at the memory. “We wanted to travel to space so bad.”
“We also wanted to get the hell away from our circumstances.” Caleb reminded you.
You cringe, but nod. The two of you had come so far from your days in foster homes. Josephine had been a godsend when you both landed there, but the need to get off the ground was persistent. It drove both of your decisions throughout your life.
“I remember the first time we got to finally fly jets.”
The smile on Caleb’s face grew. “That was the best day of my life.”
You’re beaming with a bright smile along with him and tap his shoulder with your fist. “I’m proud of you, ya know.”
Caleb gives you a knowing smile and pokes your cheek. “I’m proud of you, too, pips.”
“Hey, Xia! Let’s take a look at this door again. Houston is checking in on our progress.” Murph's voice echoes up to both of you, and you raise an eyebrow.
“That door down in node 2 is still not closing?”
Caleb shakes his head. “It closes, but only from one side. If we try to close and seal it from our lab, it won’t work.”
With a quick tug, Caleb gulps the rest of his coffee down and hands you the empty plastic. “Take care of that, pips.”
“Caleb!”
But he just gives you one of his charming smiles and zooms off to fix another issue on the space station.
You cross your arms with a grumble. “I swear this place is falling apart…”

The atmosphere in the Houston mission control room was a tense mix of hyper-focus and low-humming static. At the center of the floor stood Sylus Qin, Lead Flight Director. He leaned over the Capcom console, hands braced against the desk, his red eyes locked on the telemetry scrolling across the main screens.
He keyed his mic, his voice cutting through the subspace chatter clear, steady, and deadpan.
“ISS, Houston on Space-to-Ground 1. Caleb, tell me you’re looking at a closed hatch, because the structural integrity displays down here are giving my flight controllers a collective migraine.”
A beat of static passed before the comms clicked open, carrying the faint, ambient whir of the station’s life support systems. Caleb’s voice filtered through, breathless but annoyingly casual. “Copy that, Houston. The good news is, the view of the Pacific out the port window is spectacular. The bad news is, Hatch Kilo-Three still has boundary issues. It absolutely refuses to commit to a relationship with the locking pins from the interior side.”
Sylus rubbed the bridge of his nose. He didn’t need to look at the schematics to know what three millimeters meant in a vacuum.
He took a long sip from his cup, the coffee lukewarm by now, before he keyed his mic again. “Three millimeters means we have an expensive screen door on a submarine, Caleb. If Node 2 loses pressure, that hatch is the only thing keeping your atmosphere from emptying into the void. I don’t want a spectacular view of the Pacific from inside a vacuum suit.”
Caleb’s voice comes in a beat later. “Understood, Boss. Though honestly, a little draft might clear out the smell of Murph’s rehydrated beef stroganoff.”
“Hey! That was a tactical lunch choice.” Murphy claps back.
Sylus smirks. At least morale is still high.
“Alright, focus up. Humor isn’t going to pressurize that bulkhead. Caleb, what’s the status on the mechanical alignment? Is the latch warped, or is it an electrical fault in the actuator?”
The joking tone evaporated from the radio link, replaced by the crisp, analytical focus of a trained crew. On the video feed, Caleb could be seen floating upside down by the hatch, a specialized torque wrench in hand, his brow furrowed as he inspected the titanium rim.
“Actuator is geen Sylus. It’s mechanical. Looks like micro-debris or thermal expansion caught the lower hinge assembly during yesterday's module swap. It’s physically preventing the locking teeth from engaging the guide tracks on the port side. If I force it, we risk stripping the gears entirely, and the door is permanently stuck open.”
Sylus exchanged a sharp glance with his Environmental Officer, who shook his head grimly. A permanently open hatch meant they couldn’t isolate the module in an emergency.
“Alright, ISS. We are officially on a ticking clock. In forty-five minutes, you hit orbital sunset.” Sylus checked his watch, mentally setting a timer. “The temperature drop is going to contract the metal, and if that hinge seizes up while it’s misaligned, we lose the module capacity entirely. Caleb, I need you to initiate a manual bleed on the hinge thermal loop. Freeze it out just enough to shrink the pin, then drive the latch home.”
The radio feedback sounds like static from the atmospheric interference, until Caleb’s clear voice comes through. “Copy that, Houston. Manual thermal bleed. It’s going to be a cold fix.”
Sylus smiles when he responds, “Do it right, Caleb. I’d hate to have to write a report explaining why my best orbital engineer got locked out of his own bedroom.”
There’s a faint chuckle over the static. “Loud and clear, Houston. Prepping the tools now. Keep the coffee warm for us down there.”

Everyone was settled into their sleeping pods except you. You knew you should be sleeping, but you couldn't turn your mind off. Ever since the door issues, extra maintenance and equipment checks were added to everyone's tasks. You understood the why behind it, but it was really making it hard to pull your mind out of task mode during rest periods.
You decide that maybe doing some laps on one of the treadmills could help with the wind-down. As you head to where the exercise equipment is strapped down, you catch Caleb with his back to you doing the same thing you were planning to do.
With a mischievous glint in your eyes, you give yourself a good squat before zooming towards him, kicking off the wall. You're like a silent torpedo zeroing in on its target.
"Gotcha." You mumble to yourself as your arms are prepared to wrap around him like a koala.
But, at the last second, Caleb flips around and uses your momentum against you to spin you both in zero gravity as he holds your wrists above your head and wraps his other arm around your waist.
You try not to shriek in surprise, and it only makes Caleb's smile grow wicked as he holds you against him. His mouth is by your ear, and his breath against your neck makes you shiver. "You know I've gotten used to your petty sneak attacks, right, pips?"
The two of you continue in your spin as if you are gravity itself and the cosmos orbits around you. You're giggling into him; this silly language of play between you two spans decades and is interwoven so deeply in how you show affection.
Caleb stops you from bumping your head against a window as your travel floated you both to the other end of the module. He's laughing along with you as his hand starts caressing your face.
Your heart skips a beat as you look into his purple eyes, wondering what he's thinking right now. It seemed the two of you had stepped up to the line again, wondering who would finally be courageous and step across. This was not new territory for the both of you, and it has been slowly eating away at your resolve day after day, month after month, year after year.
"Caleb…" You don't want to break the spell, but you're not sure if this is the right moment to throw caution to the wind and bear it all to him.
He sighs, but the smile has not left him. "I know, pips. I… We are overdue for a certain conversation."
The hope that flares in your chest goes off like a bomb, and you're clutching his wrist. Before you could potentially word vomit about everything that has been on your mind, Caleb continues.
"After the mission is complete and we're back on Earth, I'm taking you to our favorite restaurant, and we will talk."
You nod, his hand still caressing your cheek. "No more deflecting."
Caleb chuckles, "No more deflecting."
"Why not have the conversation now?" You hesitate to even ask, but you have to know.
Caleb sighs, "There's not really a way to have space for after, and we need to be focused on what is going on here. I don't think I need to spell out how big of a distraction this would be if it didn't go well."
You see the wisdom in what he's saying, and you bury your face into his chest. "Okay, but you're paying for the meal when we get there."
Caleb just laughs. "Deal. Now let's get to bed."
You're still not sure if you can go to sleep, but the warmth and care you feel towards him is undeniable. The future has a lot of unknowns, but you know you can get through it with Caleb by your side.

It was supposed to just be another day on the ISS. The year-long mission was getting close to the finish line, and everyone would be coming back to Earth. You and Caleb would do your celebratory hot pot when you got to go home, and then become couch potatoes as you catch up on all of your shows you missed while in space.
Fate had other plans.
The alarms didn’t chime; they shrieked.
A violent, metallic shudder tore through the International Space Station, a sickening crack that vibrated straight through the soles of your boots. The master caution lights flooded the corridors in a blinding, rhythmic crimson.
Automated System: Warning. Pressure drop in Sector 3. Fire detected in Node 1. Evacuate immediately.
Thick, acrid smoke—black and choking in microgravity—began to billow from the ventilation shafts. Chaos erupted over the comms. Houston was a chorus of fragmented overlapping voices, but the local intercom was entirely cut off by static. Murphy and others were already shoving emergency packs into the safe module past Node 2, yelling for everyone to move.
“What the hell is going on?!” You yell at Murphy, but she’s grabbed your arm.
“Space debris hit us. We need to get out of this section of the station.”
Before you could ask more questions, you heard a boom and turned to see flames blooming near you.
You scrambled through the hatchway, the heat of the fire crawling up your spine. But when you turned to pull Caleb through, he wasn't following.
He was standing on the hazardous side of Hatch Kilo-Three.
The structural warp from the debris impact had completely ruined the automated alignment. The hatch was fighting the pressure, bowing outward, a terrifying whistle of escaping air beginning to hiss around the rim.
Caleb had his boots braced against the opposite bulkhead, his gloved hands white-knuckled on the manual lever bar, physically throwing his entire body weight against the door to force the locking pins into place.
"Caleb! Get through! Let it go!" you screamed, lunging back toward the opening.
Murphy grabbed your jacket, hauling you back into the safe module. "If he lets go, the pressure differential will rip this entire bulkhead open! We'll all go with it!"
You slammed your hands against the thick, double-paned glass viewport of the hatch. “Caleb, please! Step through! We can seal it together!”
Through the glass, the chaotic red-flashing lights cast his face in stark shadows. The comms in your headset were dead; nothing but a high-pitched, empty hiss. You couldn't hear a single thing he was saying.
But you could see him.
There was no panic in his face. The boy-next-door who had grown up alongside you, who had shared every mundane childhood summer and every terrifying milestone, just looked at you through the glass. His purple eyes, completely clear and devoid of fear, held a profound, calm resolve.
His lips moved, shaping words you couldn't hear.
It's okay, pips.
He gave the lever bar one final, brutal shove, locking the safe side pins completely into place. Secure. Protected.
Then, he let go.
The failure was instantaneous.
Behind Caleb, the outer hull of the compromised module tore open like wet paper. There was no roaring explosion because space is a vacuum, and it steals sound before it can even form. Instead, it was a terrifying, silent implosion of physics.
The air in his module turned into a violent white fog of flash-frozen moisture. The structural walls buckled outward into the blackness, disintegrating in a flash of tearing titanium and insulation.
With a sickening, silent velocity, the vacuum claimed everything.
Caleb was swept backward into the star-flecked void. For one agonizing split second, his silhouette was perfectly framed against the brilliant, blue curve of the Earth… the very view you had just been admiring together.
And then, he was gone.
The heavy titanium hatch of Kilo-Three stood perfectly still, sealed tight.
The silence inside was deafening. The crimson emergency lights continued to rotate, casting rhythmic red arcs across the empty glass viewport where his face had been just seconds before. Murphy was saying something, her hands gripping your shoulders, but the sound felt miles away, drowned out by the ringing in your ears.
You stared at the blank glass, your hands still pressed flat against the metal, your mind entirely locked in a state of absolute, paralyzing shock.

Earth’s gravity didn’t just pull at your boots; it felt like a physical weight pressing down on your chest. After months in orbit, the simple act of standing upright in a formal uniform was exhausting. But nothing compared to the crushing weight of the empty casket.
The NASA memorial was a blur of polished brass, crisp dress uniforms, and the low, solemn drone of a trumpet playing Taps. Everyone spoke of Caleb as a hero. They used words like sacrifice, valor, and frontier.
But to you, he wasn't a historical footnote. He was the boy with the messy dark brown hair who used to look over the backyard fence, the man whose purple eyes had held your gaze through a pane of glass while the universe tore itself apart.
When the folded flag was handed to you, the reality finally broke through your shock. A quiet gasp escaped your throat, your knees buckling slightly under the sudden, agonizing wave of grief.
Before you could fall, a steady, solid grip wrapped around your arms.
You didn't have to look up to know it was Sylus. He didn't offer empty platitudes. He just stood there, a silent, unyielding pillar against the wind, anchoring you to the earth when your entire world was spinning out of orbit.
Time passed in a strange, disjointed haze. Re-learning how to live on Earth was a grueling process.
For the first few weeks, you kept accidentally dropping pens and coffee mugs, your brain still foolishly expecting them to float in mid-air.
The quiet of a suburban apartment was terrifying compared to the constant, comforting hum of the ISS life support systems. Every silence felt like the vacuum that took him.
Sylus became the one constant in the drift. He was no longer the commanding Flight Director barking orders from a Houston console; he was just there.
He adjusted his schedule to match your erratic sleep patterns. He would show up at your apartment under the guise of "dropping off paperwork," but the paperwork would inevitably be accompanied by a grocery bag of actual food, or a toolkit to fix a leaky faucet you’d been ignoring. He never forced you to talk about that day. He simply filled the empty spaces with a quiet, grounding presence.
Months passed by like this, and you found yourself offering pieces of yourself to him, and he did the same. He told you about his childhood and what it was like growing up with an alcoholic for a father. You shared with him about yours and Caleb's childhood, moving from home to home in the foster system until you found a permanent spot in Josephine's home. How her slowly succumbing to cancer made a small part of your soul die along with her.
You realized in these conversations that there wasn't a single part of your life without Caleb's fingerprints on it. So how in the hell were you supposed to keep going without him?
It was a rainy Tuesday night when the storm inside you finally collided with the storm outside. You were sitting on the kitchen floor, staring at an old, faded Polaroid of you and Caleb from a summer spent at the lake.
The knock on the door was soft, rhythmic. Sylus.
When you opened it, he took one look at your tear-stained face, the photo gripped tightly in your hand, and stepped inside. He took the damp coat off his shoulders, set down a travel mug of tea, and sat right down on the hardwood floor next to you.
"You don't have to carry it all by yourself," Sylus said softly, his deep voice cutting through the sound of the rain against the glass.
"It feels like if I let go of the pain, I’m letting go of him," you whispered, your voice cracking.
Sylus turned to face you, his red eyes intense, filled with a raw, fierce empathy. He reached out, his large hand gently covering yours—the one holding the photograph. His skin was warm, a stark contrast to the cold memory of the station.
For a long, suspended moment, the air in the room shifted.
The space between you shrunk to almost nothing. You looked at the sharp line of his jaw, the genuine devotion in his eyes, and you felt the undeniable, magnetic pull toward him. It wasn't just gratitude; it was a desperate, aching need to feel alive, to be held by someone who understood the depth of the void you had returned from.
Sylus’s gaze dropped to your lips, then back to your eyes. His breath hitched. His thumb stroked the back of your hand, a heavy, lingering gesture that promised everything if you just leaned in. The tension hung in the air like an electric current, thick and suffocating.
You thought you wanted to cross that line. You wanted to bury your face in his shoulder and forget the stars.
But as you looked at him, the ghost of Caleb’s calm resolve flashed in your mind. The wound was too fresh, the history too vast. To step into Sylus’s arms right now would be a flight from grief, not a step toward love.
Slowly, gently, you turned your hand beneath his, squeezing his fingers in a silent thank you, but subtly pulling the photograph back toward your chest.
Sylus caught the shift instantly. A look of quiet understanding passed over his face. He didn't push. He didn't pull away entirely, either. He just let his hand rest on the floor next to yours, a hair's breadth away—close enough to offer warmth, but respectful of the boundary you couldn't cross.
"I'm here," he murmured, leaning his head back against the kitchen cabinets. "As long as it takes."
And there you stayed, side by side in the quiet kitchen, perfectly balanced on the edge of what could be, wondering if the gravity of the past would one day let go.

The briefing file was classified as Top Secret and "need to know". It didn’t have a standard mission number, just a codename: Acheron Station. A deep-space research platform positioned on the jagged edge of a supermassive black hole’s event horizon, far beyond the edges of any known public missions to space.
The physics were absolute. The fuel required to escape the gravitational pull of a singularity after crossing the threshold didn't exist. It was a mission of pure data collection, and a guaranteed one-way trip.
When your name appeared on the approved manifest, the door to the office you occupied didn't just open; it slammed.
Sylus didn’t look like a Flight Director anymore. His tie was loosened, his jacket gone, and his eyes—usually so calculated and steady—were dark with a frantic, suppressed fury. He threw the printed manifest onto the desk between you.
His lip quivered as he looked at you. "Tell me this is a system error. Tell me you didn't just sign up to throw yourself into a cosmic furnace."
You take a moment to steel your resolve. "It's not an error, Sylus. They need an orbital specialist who can handle high-stress structural telemetry. I qualify."
"You qualify for a suicide mission!" You had never heard Sylus' voice boom off the walls like that before. "There is no return trajectory; do you understand that? The math ends in zero. You go out there, and you never, ever come back."
He stepped closer, the commanding facade cracking completely. He reached out, his hands hovering just inches from your shoulders, wanting to shake you, wanting to hold you, but entirely paralyzed by the boundary you had drawn in your kitchen.
Sylus sighs, running his hand through his white hair. "Why are you doing this? Is it the grief? Because if it's the pain, I am right here. I have been right here, holding the line for you. You don't have to flee the planet to escape it."
You scoff, "I'm not fleeing, Sylus. I'm choosing."
"You're choosing death!"
You slam your hands on the desk as you stand. "I'm choosing the only thing that makes sense anymore!"
The shout echoed off the sterile walls, leaving a heavy, suffocating silence in its wake. You looked down at your hands, feeling the crushing pull of Earth's gravity that had felt like a prison ever since you touched down from the ISS.
You gave each other a moment to calm down before you felt your chest break open from the agonizing truth you had held in your heart. "There's nothing left for me down here. Every street, every house, every empty room... It’s just ghosts. Caleb didn't want to just look at Earth from an orbit, Sylus. He wanted the deep stars. He wanted to see what was beyond the curtain. If I'm going to spend the rest of my life in space, I want it to be where he always dreamed of going."
Sylus flinched as if physically struck. The mention of Caleb’s name was a phantom barrier between you that he knew he could never break. He looked at you, his chest heaving, his eyes burning with an intense, agonizing mix of profound devotion and helplessness.
For a second, the tension from that rainy night returned, sharper and more desperate. Sylus looked like he was on the verge of dropping to his knees, of begging you, of crossing every line to tell you that he was something worth staying on Earth for.
Instead, his hands slowly dropped to his sides. His jaw clenched, a mask of profound, quiet heartbreak settling over his features.
"I can't stop you, can I?"
With a heavy breath, you look at him and softly reply, "No."
You wanted to wrap him in a tight hug and tell him it would be okay, but you knew, deep down, you were hurting him. Maybe you would come to regret this, or maybe you would find peace beyond the edges of the known galaxy. You just hoped that Sylus would forgive you for this one day.
Sylus pinched the bridge of his nose before letting go of a long exhale. "Then God help me... because I have to be the one who authorizes the launch."

Preparing for a mission of this magnitude meant stripping away everything non-essential. You couldn't take a life's worth of belongings into the dark reaches of space. You only needed the things that defined your soul.
On the night before launch, you placed a handful of items into your standard-issue personal effects pouch. You had a small stack of physical photos: the summer at the lake where you wore silly matching swimwear, you and Caleb posing in front of a fighter jet flipping the camera off, and a candid shot Caleb had taken of you smiling with the wind in your hair.
Then there was Caleb’s silver dog-tag necklace you had made for him a long time ago, with the engraving "When U Come Back".
You didn't put the necklace in the pouch. Instead, you looped the cold, stainless steel chain around your neck, letting the heavy metal tag rest directly against your collarbone, right over your heartbeat.
“I’m taking you with me,” you whispered into the quiet room. “We’re going to see the stars.”

The gantry of the deep-space transport vehicle loomed against the night sky, illuminated by floodlights. As you and your team walked up the catwalk in your advanced pressure suit, the comms clicked open in your helmet.
It wasn't the standard Capcom controller. It was Sylus, speaking from the master console back in Houston. His voice was thick, tightly controlled, but carrying a depth of emotion that vibrated straight to your heart.
"Vessel is cleared for main engine start. Godspeed, Commander. Find what you're looking for out there among the stars."
You didn't reply with standard protocol. You just looked back towards the elevator and the waiting engineers one last time, pressed a gloved hand against the dog tags resting beneath your suit, and stepped into the airlock of the rocket.
