Illuminated Heart
Summary: At an Obon lantern festival by the river, Ren offers to release both lanterns himself so you don't have to wade into the cold water. While he's caught up watching the river glow, you sneak a few photos of him on his own phone which turns into a chase along the bank when he catches you, and ends with him grabbing you before you can get away. Surrounded by thousands of lanterns, the teasing fades into something quieter. Later, without you noticing, Ren takes a photo of you too, and can't bring himself to delete it. By the end, neither of you wants to let go of what the night gave you. ⌯⌲ BGM: Lunar Ripples
The evening tide lapped quietly against the riverbank, carrying with it countless paper lanterns that shimmered like stars scattered across the river. Their amber glow rippled over the dark water, blending with the indigo of twilight until the river itself seemed to breathe light. Around the riverbank, conversations softened into murmurs, as though everyone knew this moment deserved reverence.
Each lantern carried a wish; a farewell, a prayer.
It was said that during Obon, these floating lights guided ancestral souls back to the spirit world after their time among the living. Watching hundreds of them drift together was enough to quiet even the busiest of hearts.
You cradled two lanterns carefully in your arms, admiring the delicate floral patterns pressed into the translucent paper. A tiny candle flickered inside each one, casting warm light against your pink yukata.
"They're prettier up close," you whispered.
Beside you, Ren looked from the lanterns to the edge of the water, where people were stepping carefully into the shallow river to release theirs.
"...Oi."
"Hm?"
"You're not planning to go in there, are you?"
You looked up innocently. "I was."
"You'll get soaked."
"I'll roll my sleeves up."
"The rocks are slippery."
"I'll be careful."
Before you got far, he sighed heavily. "Give them to me."
You blinked. "What?"
"The lanterns. I'll do it." His answer came almost immediately, though he avoided your eyes while he said it.
"You don't need to."
"..." He rubbed the back of his neck. "Because if you slip and fall, that'll become my problem."
"Your problem?"
"You'll probably catch a cold and then you'll complain."
"I really wouldn't." You laughed quietly. "That's awfully considerate of you."
"I'm not being considerate. I'm just avoiding trouble." His expression stayed flat, though the tips of his ears gave him away. "...Besides, your yukata will get wet."
You looked down at your sleeves, then back at him. "You noticed."
"I have eyes."
A breeze drifted in from the river. For someone who insisted he hated trouble, he'd been the one quietly watching over you all evening; guiding you around crowded paths, handing you napkins before you asked, and now this. His actions rarely matched his words.
You smiled. "Alright." You handed him both lanterns. He took them gently, careful not to tilt either one enough to snuff the candle inside.
Just as he turned to walk toward the water, he stopped. "...Ah. My phone." He pulled it from his pocket and stared at it for a second. He looked at you. "...Hold this."
You blinked in surprise as he placed the phone in your hands. "You're trusting me with your phone?"
"I don't trust water."
"That's not what I asked."
"It'd be a pain if it got wet."
He'd handed it over without much hesitation. You turned it over curiously. "You really don't mind?"
"Just don't drop it. And don't look through it."
"...I wasn't going to."
"You hesitated."
"I was offended."
"You were tempted."
"Maybe a little."
"I knew it."
You puffed your cheeks. "I have dignity."
"Mhm."
"Hey."
"I'm agreeing with you."
"You're making fun of me."
"I'm not."
"You absolutely are."
A tiny smile tugged at his lips and vanished almost as fast. "Whatever." He turned before you could tease him further.
The water reached just above his ankles as he stepped carefully across the wet sand, paying close attention to every step so he wouldn't disturb the flames. The golden light reflected off the waves, surrounding him with shimmering halos. When he crouched near the water, the lantern in his hands lit the sharp lines of his face, softening his usually sleepy expression and catching amber highlights in his hair. He lowered your lantern first, with more tenderness than you expected, and waited for it to float steady before setting his own beside it. The two lanterns drifted together, neither one pulled away.
You stared. Maybe it was the atmosphere, or the flow of floating lights around him, or maybe it was just that Ren looked beautiful. There was something peaceful about watching someone who complained about everything treat this small tradition with quiet respect.
He watched a moment longer, making sure neither lantern tipped, then began to stand. You glanced down as his phone was still in your hands.
"He doesn't have to know." The lock screen was already open. "...Just one." Your thumb tapped the camera and you raised the phone.
Through the screen he looked even more striking, golden lanterns floating around him like fallen stars, the water throwing back every flicker of light. His expression stayed calm as he watched your lantern drift away.
*Click.*
You checked the picture. "One more." *Click.* Even better. "Okay, maybe one last—" *Click.* Perfect. "...I'm definitely keeping these."
"Hey."
Your shoulders jumped. Ren was staring straight at you from several meters off.
"...Uh-oh."
He narrowed his eyes. "Were you just using my phone?"
You hid it behind your back. "...No."
"That was the worst lie I've ever heard." He started walking back, water rippling around his ankles. "You literally had the camera pointed at me."
"I was taking pictures of the lanterns."
"...With me in the middle?"
"They're compositions."
"You mean I'm the composition."
"Exactly."
He stopped a few steps in front of you, water dripping from the hem of his pants. "Give it."
"No."
His eyebrow twitched. "Excuse me?"
"I said hand it over. They're embarrassing."
"They're beautiful." You tilted your head. "I think you look handsome."
Ren froze. "W-What?"
"I said you look handsome."
He looked away so fast you almost laughed. The tips of his ears turned pink under the lantern light. "Don't say stuff like that so casually."
"Why?"
"It's weird."
"It isn't."
"It is."
"I was just telling the truth."
His face grew warmer. "...You're seriously troublesome."
"I thought you said I wasn't supposed to cause trouble."
"So whose fault is this?"
"Yours." You laughed.
Ren pinched the bridge of his nose and held out his hand. "Phone."
"No."
"I'm serious."
He stepped forward. You stepped back. "...Don't."
"I'm just getting my phone."
"You'll delete them."
"I will."
"You look too good!"
"I don't care!"
"I do!"
Ren stared at you for a few seconds. "You seriously aren't giving it back."
You smiled sweetly. "Nope."
"Fine." His shoulders slumped, and for a second you thought he'd given up. Then he stepped forward and fast.
Your eyes widened. "Wait—" You turned on your heel and ran, laughing. "I'm running!"
"You what?!"
You darted across the riverbank, sand slowing your steps just enough to hear his groan behind you. "Seriously?!"
"You'll delete them!"
"Because they're embarrassing!"
"They're memories!"
"They're evidence!"
"Evidence of what?"
"Nothing!"
You laughed harder. Festival-goers watched with amused smiles as the two of you wove around groups by the lantern ceremony. Ren wasn't sprinting, he looked far too annoyed to call it that but, he was catching up fast anyway.
"You know," you called over your shoulder, "for someone who hates trouble, you're putting in a lot of effort!"
"This is the trouble!"
"You started it!"
"You hijacked my camera!"
"I improved your gallery!"
"My gallery was fine!"
"It had food and other stuff of pictures!"
"...they’re important!"
"And now it has handsome Ren pictures too!"
"Stop saying that!"
His voice cracked just enough to make you laugh even harder. You glanced behind you and realized he was much closer than before. "W-Wait—" Your pace quickened. "Oh no."
"You're slowing down."
"The sand's unfair!"
"You should've thought of that before stealing my phone."
"I didn't steal it!"
"You refused to return it!"
"Details!"
You dodged around a family. Ren followed, the faintest smile threatening his face, one he stubbornly refused to acknowledge. You risked another glance behind you and it was a big mistake. The distraction made your sandal sink into the loose sand, your balance faltering just enough for him to close the distance.
"Got you." One arm slipped around your waist and your feet left the sand for a moment before finding solid ground again.
"Wah—!" Your laughter cut off into a gasp as the momentum carried you back against him.
"You're kidding."
"I told you I'd catch you." His voice came from closer than you expected, warm and slightly breathless.
You reached for the arm around your waist, fingers curling around his sleeve. His grip wasn't rough, but it was firm and careful, like he was making sure you couldn't run without ever making it feel like he was holding you too tight.
His breathing was still uneven from the chase, each breath brushing the top of your head. Only then did you notice he was still holding you, closer than he'd ever been, his arm resting around your waist as if he'd forgotten it was there. Or maybe he hadn't realized how naturally it had ended up there.
Your heartbeat got loud enough to drown out the festival music. Neither of you said anything for a moment, both still catching your breath. You could feel the rise and fall of his chest behind you, warm despite the cool evening air.
He's really close, you thought. Closer than he'd ever been before.
"A-Alright." Your voice came out softer than you meant. "I'll give your phone back. Just don't delete the pictures."
Ren stayed quiet.
"Please?" There was something genuine in the way you said it now, not a joke anymore. You wanted to keep them. The lantern light had caught him at the perfect moment: calm, gentle, an expression not many people got to see.
He sighed. "You really like them?"
You nodded. "They're beautiful."
"The lanterns?"
"You."
He stiffened. "Stop saying things like that. I don't know how to respond."
"You don't have to. I just wanted you to know."
He stared out at the glowing ocean for a while, his ears unmistakably red. "...Fine. Keep them. On one condition. You don't show anyone, and you don't make it your wallpaper."
"I wasn't planning to."
"You hesitated."
"I was thinking, maybe for like five minutes."
"Absolutely not."
You laughed. "Okay, okay. I promise."
He studied your face, satisfied, and loosened his hold, except he didn't actually let go.
"Ren. You're still holding me."
His eyes widened, as if he'd only just noticed himself. He stepped back fast, his face flushing. "I— sorry."
"No, it's okay." You touched the spot at your waist where his arm had been.
An awkward silence settled in, neither of you knew where to look.
"Here's your phone," you said, holding out the phone.
He took it and unlocked the screen before putting it away. The gallery opened, three new photos, all of him.
He stared at the first one; golden lanterns floating around him, the river shimmering under his feet, the light softening the tiredness in his face. "That's... not terrible."
You beamed. "I told you, I’m a pro photographer."
"Don't get smug." A small, almost invisible smile crossed his mouth before he could stop it.
"You smiled."
"I didn't."
"You definitely did."
"It’s the lighting."
"The lighting smiled?"
"...Shut up."
You couldn't stop laughing. He looked away, muttering under his breath, but he never reopened the delete menu. He just locked the phone and slipped it back into his pocket.
"Come on. The lanterns are getting farther away."
You followed his gaze. The river had become a flow of light; hundreds, maybe thousands, of lanterns drifting toward the horizon, their reflections stretching across the water like pieces of the night sky brought down to earth. Without another word, the two of you walked toward the riverbank together, and this time neither of you ran. The festival behind you faded into a pleasant murmur, every so often another lantern went out to the river, joining the ones already drifting toward the horizon.
You slowed without meaning to. "...Wow." The river had transformed, the lanterns floated together like a constellation on the water, their reflections stretching farther than you could follow. The sky above had gone darker, letting every flame shine brighter, as if the stars had come down to rest on the river instead. "It's beautiful."
Ren stood quietly beside you. "Yeah." His reply was almost lost under the waves. For someone who always had a complaint ready, he had nothing to say now. Maybe because there wasn't anything worth complaining about, or maybe because even he couldn't find words for the view. The two lanterns you'd released were somewhere out there among the others, impossible to pick out anymore.
You stepped closer to the water and folded your hands in front of your chest.
Ren glanced over. "What're you doing?"
"I'm praying."
"...Oh." His voice softened.
You closed your eyes. You'd read about the meaning of the ceremony before coming. These lanterns guided ancestral spirits back after their visit among the living. Not a lonely farewell, but a promise that they'd be remembered.
May every soul find their way home safely. May those waiting beyond the light know they're loved… and may everyone precious to me continue smiling.
The breeze swept across the riverbank as if carrying the prayer out to the endless river. You opened your eyes, and the sight before you looked even more beautiful than before.
You didn't notice that Ren wasn't looking at the lanterns anymore. He was looking at you, your smile, the candlelight softening your features, and the quiet happiness in your expression. It was different from your usual energy, the teasing and laughing and dragging him into conversations he claimed he didn't want. Right now you were simply standing there, peacefully.
He blinked, caught himself staring, and looked away. Only for his eyes to drift back again.
What's wrong with me, he thought, clicking his tongue quietly. It's just the lighting. Anyone would look nice with this many lanterns, probably. Without quite deciding to, his hand found his phone. He frowned. That's stupid. His thumb hooked the edge anyway and he pulled it out. Your photos of him still sat at the top of his gallery. He looked at them for a second before switching to the camera. The lanterns framed you perfectly, the river glowing behind you, the breeze stirring the ribbon on your yukata. You were too caught up in the lights to notice him at all.
*Click.* The sound was almost nothing, he lowered the phone and looked at the picture.
It looked really nice, not because of any sudden skill with a camera or a lucky angle, but because it caught exactly how he saw you in that moment: smiling quietly under a sky of floating lights, like you belonged among them.
His thumb hovered over the trash icon. Delete it, he thought. It'd only be trouble later. If you found out, you'd never let him hear the end of it, he could already picture your smug face and the teasing. His ears warmed just thinking about it. He should delete it. His thumb moved, then stopped.
...It'd be a waste, he told himself. The lighting was good, the composition was good. Deleting a perfectly fine photo would just be inefficient. That was the only reason.
"Yeah," he muttered, nodding once as if convincing himself. "It'd be a waste."
Just as he locked the screen, you turned around.
"Ren?" He nearly jumped. Your eyes narrowed. "Were you looking at your phone?"
"Maybe."
"Were you taking pictures?"
"No."
"Ren, show me."
"No."
Your eyes lit up. "You definitely took one!"
"I didn't." He calmly pocketed the phone. You gasped. "...You're hiding evidence!"
"There isn't any."
"There is now."
Before you'd finished the sentence, you lunged. "Gotcha!"
"H-Hey—" He stepped back, lifting the phone over his head before you could reach it.
"You did take one!"
"I did not!"
"Then let me see!"
"No!"
"You saw mine!"
"You forced me to! You blackmailed me with compliments!"
"They were genuine!"
"That's worse!"
You laughed and stretched as high as you could. "C'mon... please."
"No."
"I'm shorter than you. You're using your height unfairly."
"That's usually how height works."
You pouted, then stepped closer. "Fine." When he wouldn't lower his arm, you rose onto your toes and reached, still too short. "So close." One more try, your fingers barely brushed his wrist. Without thinking, your left hand landed against his chest to steady yourself while your right kept reaching. "Almost—"
Ren stopped moving completely. His raised arm froze mid-air, his breath catching. Your palm rested right over his heartbeat through the fabric of his clothes. You finally noticed he wasn't resisting anymore, and looked down from the phone to find his eyes already on yours.
Somehow, without either of you noticing, you'd ended up impossibly close, close enough that if either of you leaned forward even slightly, your lips would meet. Neither of you moved, even the festival seemed to fade, leaving only the hush of the waves and the soft crackle of lantern flames drifting out to the river.
Your own heartbeat was too loud in your ears. You hadn't realized how close you'd gotten, close enough to count the strands of his hair falling across his forehead, close enough to see the lanterns reflected in his pale blue eyes, close enough to feel every slow breath he took. Ren had forgotten about the phone entirely, forgotten why he'd lifted it over his head, forgotten that you'd been chasing him for it only a minute ago. His mind had gone blank.
She's too close.
Your hand was still on his chest, warm through the layers of fabric, every small shift of your fingers impossible not to notice. His heartbeat gave him away immediately.
She's definitely hearing this, he thought. Seriously?
He wanted to say something, step back, complain — anything but none of it happened, he just stared. Your eyes widened as the same realization hit you. We're really close.
Neither of you looked away after how many seconds had passed. Your gaze dropped for the briefest moment to his lips before you caught yourself and pulled it back up, but not fast enough. Ren had noticed, and his ears burned red.
Did she just— No. She probably didn't, right?
Your cheeks were warming by the second, and the breeze that should have cooled you down only made you more aware of it.
"R-Ren." His name came out barely above a whisper.
"Yeah?" His voice was just as unsteady.
Neither of you finished the thought, you just kept looking at each other. There wasn't embarrassment in his eyes anymore, only hesitation like he was trying to decide something.
The hand holding his phone lowered, he had realized you were leaning farther than you probably meant to. If he moved wrong, you'd lose your balance. Without thinking, his free hand found your waist again. This time it wasn't to stop you from running. It was instinct, his palm settling against your side, steady enough to catch you if your footing slipped, careful not to hold you any tighter than that.
Your breath caught. His hand was warmer than the night air, and you could feel exactly how much space he was leaving, like he didn't want to hold you any closer than necessary.
He swallowed. "You'll fall." The excuse sounded weak even to him.
You almost smiled. "I'm standing."
"Barely."
"You're the one holding me."
"Right." Neither of you moved to change that.
The lanterns kept drifting behind you, flickering gold across both your faces. For one long moment it felt like the whole world had slowed down just for the two of you.
Would he close the distance? Even a little? Your heart answered before you could think it through, leaping against your ribs. His gaze flicked down again, just once, then back to your eyes. His fingers tightened slightly around your waist not pulling you closer, just steadying you.
He inhaled quietly. What am I doing? He'd never been good at moments like this, never known the right move. Kissing you felt like crossing a line he wasn't sure he had permission to cross, even if part of him wanted to. The thought alone made his face burn hotter. Idiot. Why are you even thinking about that? She's probably just trying to steal your phone.
You were thinking almost the same thing. Should I— no, that's weird, too sudden. He's probably just making sure I don't fall. Right?
The silence stretched until you gave a small cough. "A-Ah—" Reality returned all at once. You lowered your hand from his chest and stepped back. "Sorry."
His hand slipped from your waist, the sudden absence of warmth felt strangely obvious.
He looked away first. "...Sorry."
"For what?"
"Holding you."
"You were helping me."
"...Still."
"It didn't bother me." You laughed awkwardly. "I almost forgot. Your phone, I never even got to see it."
His eyes widened for half a second. "...No."
"Ren, you definitely took one."
"...Maybe."
"Aha!"
"I didn't say that."
"You basically did."
You stepped toward him, and this time he didn't run. He unlocked the phone instead. He stared at the screen for a long moment before turning it toward you. A photo filled the display and it’s you, standing before a number of floating lanterns, your smile lit by their glow, the river stretching endlessly behind you. It looked like more than a picture, it looked like it had caught the quiet happiness of the moment itself.
He looked at it once more, then locked the phone without deleting it and put it away.
You puffed out your cheeks. "Mean."
He glanced at you sideways. "It's embarrassing."
"Why?"
He searched for an excuse and couldn't find one. Finally he sighed. "If I show you, you'll know I wasn't looking at the lanterns."
You stared at him. His own eyes widened at what he'd just admitted. "Forget I said that."
A slow, genuine smile spread across your face. You didn't tease him this time. You just looked back out at the glowing river. "Then don't delete the photos we took today, they're memories. Cherish them from now on, even the embarrassing ones."
Ren said nothing for a long while. The waves kept rolling in, the lanterns kept drifting into the darkness, carrying their prayers toward the horizon. At last he slipped a hand into his pocket, his thumb brushing the phone inside.
"Yeah."
It was only a single word, quiet, almost swallowed by the breeze. But he never once thought about deleting the photographs again, not yours and especially not his.
