masterlist

part 1

its a little bit of a different format!! be warned because i know the first part was well loved

this is technically a part 2 though its a little more angsty but I tried to still hold the same dynamic. Sunday having some self doubt is a warning. You don’t need to read this part but you’d need to read the first part to make this make sense.

˚₊‧꒰ა ☆ ໒꒱ ‧₊˚ Something cold brushed your cheek. You stirred, barely, burying your face deeper into the couch cushion. The blanket someone had kindly placed over you was warm and smelled faintly of lavender. The lights in the Parlor Car had dimmed. The stars outside twinkled lazily, unmoving.

“HEY! HEY! WAKE UP!!”

“AAAHHH” Your body spasmed upright as your eyes flew open in a panic. You blinked wildly, sleep still clawing at the corners of your vision. Something someone was screaming directly into your ear, high pitched and furious and

“We’re about to make a jump! All passengers must be prepped and present! Did you think this was a nap train?! Come on, come on!”

“PomPom?” you croaked, eyes wide and dazed, hair in complete disarray. the tiny conductor screeched, arms flailing, foot tapping with enough force you swore you could feel it through the couch. “We jump in fifteen minutes! FIFTY FIVE SECONDS of that are already gone! Do you want to arrive half dreaming and in pajamas?!”

You blinked again, your heart now racing for a whole new reason. The blanket slid off your shoulders. Across the room, seated calmly with tea in hand, Welt Yang gave you an apologetic nod as if this sort of thing wasnt normal. Beside him, Himeko, already dressed in her usual beautiful self with not a single red strand out of place, smiled gently. “Good morning, sleepyhead. You should hurry. These jumps can be disorienting if you’re not prepared.”

“Right. Yes. Okay. Jump. We’re jumping.” You stood too fast. The blanket tripped you. Your leg knocked into the table, rattling Himeko’s teacup. “Sorry! Sorry. I!”

“Just go get dressed!” PomPom wailed. “You’re embarrassing me”

You scrambled out of the Parlor Car, heart pounding, brain trying to catch up to your body.The halls of the Astral Express were softly lit, calm in contrast to your internal panic. You stumbled into your room, kicked the door shut behind you, and launched into the most frantic wardrobe selection of your life. Pajamas off. Shirt on backwards. Fixed. Pants? Where were your pants? Oh god, you’d slept in one sock and now you were wearing mismatched ones but there wasn’t time to change. You brushed your hair with your fingers, tied it up…. was that a feather from last night still in there? You stopped. Looked in the mirror. Your cheeks were flushed. There were faint sleep lines on one side of your face. But your eyes were awake now alive with motion, with chaos. And as you adjusted your jacket and took one last breath, you had a glimpse of something else.

The navy blue blanket where you’d tossed it before rushing out.

Sunday.

You paused, just for a moment. The memory of his soft voice in your sleep though you hadn’t really heard the words lingered faintly, like a dream half remembered. Had he really just sat there and let you rest? You smiled without meaning to, but only for a moment. Pom Pom’s voice echoed from the hallway again.

“FIVE MINUTES! And not a second more!”

“Coming!” you yelled, grabbing your boots and stumbling out of the room like a storm with arms. You arrived at the boarding deck just as the others began gathering. Caelus was still tugging on his coat, March was fixing her scarf as if her entire existence depended on the perfect loop, and Dan Heng had been ready fifteen minutes ago and clearly didn’t understand why the rest of you looked like you’d been hit by a comet. Sunday was there too. Fully dressed. Elegant even in simplicity. His hair was slicked back, a calm expression on his face as he glanced your way and then, just for a second, something softened in his gaze when he saw you.

“Sleep well?” he asked quietly as you joined the group.

You nodded, tugging your jacket into place. “Yeah. Thanks for the blanket.”

He tilted his head. “Seemed like you had an adventurous night?”

You blinked at him. But his eyes sparkled, just a little. The floor beneath your feet gave a small rumble. Lights along the ceiling began to pulse with color. Pom Pom stood atop the central platform, now fully in Conductor Mode, voice echoing with more authority than their small frame should’ve ever allowed.

“Next stop,” Pom-Pom announced, “an old and well met planet, we are visiting Jarilo-VI again”

The ship jumped. You barely had time to brace, but this time, it didn’t feel so disorienting. Maybe because you were surrounded by them. Your crew. Your friends. Or the fact that next to you in the parlour car, Sunday is always taking in the works around him like he was just born. So much wonder made you feel so fortunate. You weren’t entirely sure when that started to feel comforting. But it did.

˚₊‧꒰ა ☆ ໒꒱ ‧₊˚ Jarilo-VI welcomed the Astral Express crew with its usual frosty greeting icy winds sweeping the platform, snow clinging to every rooftop and ledge, and that quiet stillness in the air that only came with winter.

You stepped off the train behind the others, watching your breath fog in front of your face. The city beyond still stood proud despite its scars. Belobog had changed since you were last here less tension, more movement. There was life in the people’s steps now. A subtle, growing hope.

March was already snapping pictures of Caelus helping a local child shovel snow off the street, her voice excited and dramatic. “Sometkme i look at him and wish I had that drive but he does stuff like he has daily tasks or commissions”

Caelus was half buried in a snowbank but gave a thumbs up. Dan Heng, coat already pristine and zipped, muttered something under his breath and walked ahead toward the Administrative District. He’d been assigned to assist with a few lingering logistics, as had Himeko and Welt. The grown ups, as March dubbed them. You? You had been told absolutely nothing.

No tasks. No missions. Not even a clipboard. Which was exactly why, once everyone else had scattered, you stayed behind. Your eyes trailed over the rooftops dusted with white, the distant roads sloping down into familiar territory. Serval’s workshop, maybe. Or even a chance run in with Bronya or Gepard. Heck, you’d even take a weird monologue from Sampo as long as you weren’t standing still in the cold. You adjusted your coat and turned to sneak off “You’re not going alone, are you?”

You flinched and turned around quickly. Sunday stood just behind you on the platform, arms folded loosely across his chest, eyes squinting slightly at the sun reflecting off the snow. Still in his usual attire, not a shred of weather appropriate attire in sight. He blinked slowly, then added, “I thought I might accompany you. If you don’t mind.”

You hesitated. He didn’t ask why you were going. Just wanted to tag along.

“Sure,” you said, smiling, “but not like that. You’ll die in five minutes.”

He raised an eyebrow. “I’ve survived much worse.”

“Yeah, sure. luxury suits. Come on.”

You motioned for him to follow and dragged him back into the Express, heading straight for the storage closet where everyone’s winter gear was kept. You shoved open the door and started rummaging. He watched you with amused patience as you returned with armfuls of thick clothes. You tossed a jacket at him navy, heavy, with silver trim. He barely caught it before you were already looping a scarf around his neck, standing on tiptoe to reach properly. “Arms up,” you ordered, like he was a kindergartener and not a six foot tall enigma.

“You’re very particular about this,” he murmured as you tugged the sleeves over his arms and zipped the coat halfway up his chest.

“You probably haven’t even seen snow before,” you muttered, voice muffled as you fixed the scarf, “Pretty boy like you? I bet Penacony was all dream beaches and sun.” You tugged a beanie over his perfectly styled hair. “This would eat you alive.”

“I think I’m capable of”

“There.” You stepped back, satisfied, and grinned. “Now you look like a fashionable marshmallow.” Behind you, a suppressed snort cracked the silence. You didn’t even turn. “March, if you even think about saying anything, I’m throwing snow down your coat.” More giggling. Retreating footsteps. Sunday glanced in the direction of the sound and then looked back at you, blinking under the knit hat you’d shoved onto his head. “Am I… presentable?”

You pretended to examine him, chin in your hand like an artist judging a sculpture. “You’ll survive. If only just.”

His smile was subtle, but it reached his eyes. Together, you stepped off the train and began your slow descent into the city. Jarilo-VI was still beautiful in the way icy sunlight catching on rooftops, the clink of tools and laughter echoing from a few shops that had reopened. As you both walked, you explained what each building had been during the whole event when the astral crew were all there, and how things had changed. Sunday didn’t speak much, but he listened. Genuinely. His hands stayed in his pockets, but his eyes followed every movement children pulling sleds, old workers salting roads, steam curling from chimneys.

“It’s different here,” he said softly after a while.

You hummed. “Cold?”

“it feels like fresh air.” His breath fogged in the air. “I used to think eternity would be the only path to peace”

You turned to look at him. He shook his head. “Its so nice to see people out.” His gaze dropped to the footprints the two of you left behind in the snow. You smiled.

“Also,” he added lightly, “I haven’t felt my fingers in the past twenty minutes. So perhaps you were right.”

“Well no duh” you grinned, and bumped his shoulder gently. “Welcome to winter, dream boy.”

˚₊‧꒰ა ☆ ໒꒱ ‧₊˚ Eventually, you ended up outside Serval’s workshop, laughter and music spilling from the inside. She was strumming her guitar for a cluster of teens, everyone bundled up with hot drinks and wool scarves. The moment Serval spotted you, her eyes sparkled with mischief and she called out, “Hey! You brought a date?”

You flushed immediately. “He’s not”

“I’m here by choice,” Sunday cut in smoothly, tugging his scarf down just enough to speak clearly. His voice was calm, a slight smirk on his lips. “Don’t let her flustered denial fool you.”

You shot him a look, but he only raised a brow in amusement.

One of the teens whispered, “Is that guy famous or something?” Another murmured, “He looks like he owns a whole company.”

You buried your face in your scarf.

˚₊‧꒰ა ☆ ໒꒱ ‧₊˚ Later, as the sun dipped and shadows grew long, the two of you sat at the edge of the city, the rooftops of Belobog glowing gold beneath a dusky sky. You handed Sunday the last bit of your hot drink without looking at him. He accepted it, hands brushing yours, and took a sip.

“Thank you,” he said, his voice more serious now. “For letting me come along.”

“I didn’t do it for you,” you muttered, gaze fixed ahead. “I just needed a tall coat rack.”

There was a pause, then a soft chuckle. “Then I hope I’m fulfilling my purpose admirably.”

When you didn’t reply, he added, quieter, “I don’t take your time for granted. I’m glad to be here with you.”

That made your heart skip. You looked away, flustered, and he didn’t push. The stillness wrapped around you both like a blanket, snowflakes drifting lazily in the air. You leaned back on the bench, exhaling slowly.

“Hey! Hey, there you are!”

You both turned to find Lynx bounding up the road, scarf trailing and cheeks pink from the cold. “There’s a frozen lake just outside the city! We cleared it for skating come join us! Serval’s already out there bullying Gepard, and I need backup.”

You stood, grinning. “Say no more. I’m in.” You glanced at Sunday. “C’mon.”

He blinked, surprised. “I’m sorry what exactly are we doing?”

“Skating.”

“…That’s like walking but more dangerous?”

“You’ll be fine.” You patted his shoulder. “You’ve survived worse.”

“I’m not convinced this counts as survival.”

You were already walking, but he didn’t hesitate long. He stood with a quiet sigh, resigned but not unwilling. “I assume you’ll mock me if I fall.”

You smiled over your shoulder. “Respectfully.” You smirked. “Come on. We’ll get you moving.” He hesitated but only for a second. Lynx clapped her hands and turned back toward the main street, clearly expecting you both to follow. You tossed Sunday a look, and he reluctantly stood with that soft little sigh of surrender he always gave around you. In retrospect the lake wasn’t far just past a ridge near the edge of Belobog’s perimeter. It was tucked away like a secret winter garden. A large sheet of glassy ice shimmered in the moonlight, surrounded by snowy banks and pine trees dusted in white.

A few lanterns had been strung up between wooden poles, casting golden halos onto the lake’s surface. Music played faintly from a small speaker on the snowbank, something upbeat and old school that you suspected came from Serval’s collection. And there they were: Serval, skating backwards with way too much confidence, trying to start a conga line with a group of teens nearby. Gepard, already red in the face as he stumbled along the ice, attempting to catch up to her. You were pulling on your skates before Sunday even had a chance to decline. Lynx offered to help him get into his pair, but you shooed her off.

You stood on the lake first, gliding across the surface like it was second nature, your balance steady and posture relaxed. Lynx clapped excitedly as you looped around her, grabbing her hands and pulling her onto the ice.

“Wait wait wait!” she squealed, trying not to fall as you twirled her.

You laughed freely, cheeks flushed and heart light.

“You’re weirdly good at this!” she cried.

“I have secret skills,” you said with mock seriousness.

“I literally live here, how are you like this.” Lynx replied. you winked. Gepard was the next target.

“Hey, Captain,” you called, skating up beside him with a wide grin, “Race you to that snowbank.”

He narrowed his eyes, the same competitive spark you remembered lighting up in them. “You’re on.” Two seconds later, you were both flying across the ice, skates slicing through it with sharp precision. Three seconds after that, you crashed spectacularly into the snowbank, laughing as you rolled over onto your back and blinked up at the stars.

“You okay?” Gepard asked, snow clinging to his uniform.

“I’ve been better,” you wheezed, still laughing. Serval skated over next and dropped onto her knees beside you. “You die?”

“Spiritually.”

The next ten minutes were a blur of white flurries and screaming as Serval roped you into a full scale ambush on the Landaus. Lynx betrayed you instantly. Gepard tried to remain neutral. It didn’t work. You laughed until your stomach hurt, until your hair was full of snow and your gloves were soaked and all the while, Sunday watched from the sidelines, sitting alone on the bench near the treeline. His winter coat bundled around him, scarf you wrapped earlier still snug around his neck.

His eyes followed your every move. Your joy was loud. Free. Untamed. He watched as you threw snow with both hands, collapsed in a heap of laughter, and got back up just to do it again. Your smile wasn’t measured. It wasn’t perfect. It reminded him of what should have been. Of what he never had. His own sister had never laughed like that. Robin had smiled, yes, but it was always rehearsed duty bound. Everything in Penacony was orchestrated. Everything was planned. Conditional. watching you here, he felt it again, that strange ache. That pull toward something… unconditional. It made his chest tight.

“You’re not gonna sit there all night, are you?” Serval’s voice cut through his thoughts. He turned slowly to see her smirking down at him, hands on her hips. “Why don’t you get out there? She’ll catch you if you fall.”

“…I have no experience skating.”

“Exactly why you should.” She leaned in slightly. “You two act like you’re not into each other, but you’ve got the tension of Bronya and Seele after seeing each other for too long” His eyes flicked up to her.

She winked. “Go on, dream boy.”

You were in the middle of trying to help Lynx build a snow cat when a shadow fell over you. You turned. Sunday stood awkwardly in borrowed skates, hands in his pockets.

“…I believe I require assistance.”

Your brows lifted. “You’re actually going to try?”

“I was… encouraged.”

You snorted and skated over. “Okay, come here.” You held out your hands, and he took them without hesitation.

“Bend your knees slightly,” you instructed, “and keep your core tight.”

“I feel like I’m being trained for battle.”

“well trying anything new kinda feels like that.”

His feet slipped, and he lunged slightly but you caught him. You laughed, and he stared at you. “I will admit,” he said quietly, “the company makes it tolerable.”

You felt your smile soften. You pulled him gently along the ice, step by slow step. He clung to your hands like they were lifelines. Lynx waved at you two from across the lake. Serval gave a not so subtle thumbs up. You pretended not to see them.

˚₊‧꒰ა ☆ ໒꒱ ‧₊˚ warmth immediately spilled into your bones, melting away the bite of the Belobog chill still clinging to your coat. You stepped inside with Sunday beside you, arms still linked, boots dripping faint traces of snow onto the polished floor.

His scarf was still a little uneven where you’d adjusted it earlier, and his cheeks held the last blush of cold. His steps were careful, as they had been all night, but steadier now. You were guiding him more than anything. Not that he’d admit it.

You glanced at him as the doors closed behind you.

“You know,” you started, “I think you’ve set a record for the most times someone’s fallen in one walk.”

“I would prefer it not be the legacy I leave behind,” Sunday replied, smooth and quiet, a faint wryness in his voice. “Though you seem particularly fond of recounting each incident.”

“I’m preserving history,” you said, stifling a laugh. “Someone has to tell the tale of the Great Trip of Ten Feet Past the Bench.”

His gaze shifted down toward you, expression unreadable but fond. “If I recall, you were laughing too hard to be of any assistance.”

“I got there eventually,” you said innocently. “Besides, you falling over is weirdly elegant. Like watching a tree try to curtsy.”

That pulled a quiet breath from him, something like a laugh but more reserved. “It was… a good night.”

You smiled at that, more to yourself than anything. “Yeah. It was.”

The two of you walked a little slower now, letting the soft lights of the Express guide your path past the Parlor Car. Himeko’s voice murmured faintly from the direction of the tea table. Someone probably Dan Heng had left a book open on one of the lounge chairs.

You and Sunday paused in the corridor just before it branched off into your rooms. The moment hung there, gentle and still. He looked at you, his tone quieter now. “Thank you… for inviting me.”

You tilted your head, a little amused. “Pretty sure you invited yourself.”

“I did,” he admitted, “but you didn’t send me away.”

Your smile lingered, warm. “Wouldn’t have, even if you asked.”

He gave a small nod, the weight of the day still visible in the curve of his shoulders, but there was ease there too like something heavy had been left behind in the snow.

“I’ll see you tomorrow,” he said.

You didn’t let go of his arm right away, but when you did, your hands brushed one last time. He turned with quiet steps and disappeared down the hallway toward his room, the soft rustle of his coat fading behind him.

You stood there for a moment longer, just listening. The train hummed, steady beneath your feet. The stars drifted lazily outside the windows. Eventually, you turned and wandered toward the main lounge where March was curled up on the couch with a blanket, swiping through pictures on her camera.

She looked up as you walked in and grinned. “Okay. You have to see this one Bronya mid fall. her arms are doing this dramatic flailing thing. I swear, it’s like ballet.”

You laughed and plopped down beside her, glancing over at the tiny screen. “She did try to defend her honor.”

“Yeah, and then immediately ate ice again,” March said, beaming. “And you and Sunday? how was that today… nothing out of the ordinary…”

You rolled your eyes, reaching for a throw pillow. “You’re imagining things.”

March wiggled her eyebrows. “Sure I am.”

You stayed a few minutes longer, sharing stories, teasing each other in the soft glow of the lounge, until your body finally reminded you how tired you were. After promising to join her again tomorrow for more photo reviews, you stood with a stretch and padded quietly down the hallway. The lights dimmed slightly as you reached your door, and in the stillness, you caught yourself thinking back on the day. The snow. The skating. The way Sunday had looked at you when he said he didn’t mind being useful if it was to you.

The crew slept quietly around you. The hum of its systems was softer in the middle of the night, like even the machine itself had tucked in. You hadn’t meant to stay up this late but after tossing and turning in bed, your sweet tooth had convinced you to sneak down to the kitchen car. Just something small. A cookie or two. Maybe something warm to hold for a while.

You were on your way back now, satisfied and relaxed, your steps light as you padded barefoot through the dim halls. Most of the lights had dimmed to a faint glow, golden enough to keep the shadows at bay but soft enough not to wake anyone. A few stars shimmered lazily beyond the train windows, the galaxy at peace. Everyone else had already turned in. You were on your way to do the same when a quiet sound halted your steps near the guest car a space meant for travelers passing through, those not quite crew but not strangers either. Sunday stayed there.

Your hand hovered over the handle to your room, ready to turn in at last until you heard it. A sound. It came from the guest car just around the bend. Your brows furrowed. Everyone else had already turned in. You were on your way to do the same when a quiet sound halted your steps near the guest car a space meant for travelers passing through, those not quite crew but not strangers either. Sunday stayed there.

You stayed still, holding your breath. There it was again. A stifled breath. The kind someone might mistake for a cough if they weren’t paying attention.

But you were paying attention. It was the sound of someone trying not to cry. Your first instinct was to leave him be let him have his space, his privacy. But the image of him skating with shaking knees and guarded pride, of the way his eyes had softened during the snowball fights, lingered too vividly. The fondness you felt for him wasn’t something you could ignore. You stepped away from your door and moved toward his.

The door to his room was slightly ajar. You didn’t call out. Probably should’ve knocked. You just stepped inside quietly, drawn by something you didn’t have the words for. The room was dim, lit only by the faint starlight filtering in through the window. Sunday sat upright on the edge of the bed, his coat shrugged off and draped over the chair. He hadn’t changed for sleep. His eyes were red, his shoulders trembling just slightly. He was turned away, both hands clasped as if trying to hold himself together.

You simply knelt in front of him, your knees pressing into the floor, eyes searching his face until he finally looked down. His breath hitched at the sight of you. His lips parted like he might try to speak, but nothing came. So you offered your hand. No words. No expectations. Just your hand, palm up, waiting. He stared at it for a moment. Then, slowly hesitantly he reached out and took it. His fingers were cold. His grip was light at first, like he didn’t quite trust himself to hold on. But then he exhaled, the breath catching at the end, and he interlocked his fingers with yours. He didn’t cry again, not right away. He just breathed. Slow. Shaky. Like the pain had found a safe place to settle.

Minutes passed. And then, quietly, he spoke. “…You looked so beautiful today,” he whispered. “With the others. With that girl… her laugh reminded me of Robin’s.”

Your thumb gently brushed over the back of his hand. “She always tried to laugh like that,” he said. “But it was always… restrained. Like it had to be measured. Beautiful, but… not direct.” His voice broke. “Not like yours.”

You stayed still, grounded, letting the silence hold space for him. “I kept thinking… if she had a life like yours… if I had” He stopped, trembling again. “Every time I look at you, I learn something else I never knew I needed to value. Every gesture, every laugh, every time you reach out for someone like it’s nothing…” He shook his head, a small, helpless sound. “It teaches me what I missed. What she missed.”

You lifted your other hand to rest gently against his knee. His grip on your fingers tightened, like he needed something to hold on to.

“I’m afraid,” he admitted. “That the more I see, the more I’ll realize how empty everything I had really was. And yet, I can’t look away.”

He looked down at you again then, and in that moment, he didn’t look composed or mysterious or sharp. “I’m sorry,” he whispered. “You shouldn’t have to see me like this.”

“You don’t have to apologize,” you said softly. “Im sorry for barging in.”

He exhaled again, a little steadier now, and lowered his forehead to rest gently against yours. There was no need to say anything else just yet. You were here.

You stayed like that for a while his forehead resting lightly against yours, his hand warm and solid in your own. The silence wasn’t heavy anymore. Then, slowly, you shifted. Still kneeling, you leaned forward, resting your head gently on his legs. Your cheek pressed to the soft fabric of his trousers, and your fingers relaxed around his.

Sunday froze, just for a moment. His breath hitched again, but not from pain this time. Then his hand moved. Carefully. Tentatively. Fingers brushing through your hair. He stroked it once. Then again, slower.

The movement was gentle like he wasn’t sure he deserved to touch you this way, but needed to anyway. Like this moment was fragile, and he was terrified of breaking it. You let him comfort himself in the rhythm of it, in the quiet press of your presence. The train hummed softly beneath you both, as if it too understood the importance of silence right now.

His hand paused only once just to curl lightly at the ends of your hair, like he was memorizing the texture. Then, after a while, he shifted forward, leaning down just slightly.

His hand cupped your face, thumb grazing along your cheek with a reverence that felt almost sacred. He pressed a kiss to the top of your head. He didn’t say anything after. He just stayed there, his hand still against your cheek, his other resting in your hair.

Eventually, he sighed, a sound almost reluctant to disturb the stillness.

“…If you stay like that much longer,” he murmured, voice low and hoarse from emotion, “your neck is going to ache terribly.”

You hummed softly, not moving just yet. Still, the smallest smile ghosted across your lips.
