💙 Isagi Yoichi
Initial Reaction
He doesn’t really think about stretch marks much at all. Not because he finds them weird or gross, but because he’s just never been exposed to real, unfiltered bodies outside of sports, magazines, porn and whatnot. He's only seen them a handful of times online and honestly forgot they were a thing.
When he sees them on you You were pulling down your shorts, changing in front of your boyfriend. It was a hot day and you and Isagi were about to go out for an afternoon walk. You wanted to be in something breathable. Nothing dramatic. Just a flash of skin and there they were.
And for some reason, he couldn't look away.
He didn’t say anything in the moment. Just blinked. Let his gaze soften. And when you looked over at him, he smiled.
His eyes widened, his cheeks turning a little pink. He didn’t say anything in the moment. Didn’t comment. Didn’t stare. (for too long) Just blinked. Let his gaze soften. And when you looked over at him, he smiled. Not out of politeness. Not forced.
Just quiet.
Because they were yours. And that made them feel like something worth looking at differently.
By this point, Isagi was just staring and it was starting to freak you out, like his eyes were stuck.
"Isagi. What are you doing??" You asked, brows furrowed.
He blinked a couple times before coming to his senses, shaking his head slightly and looking away, cheeks still warm. "N-Nothing.. you're just, so pretty,” He whispered, Like he was nervous to say it himself.
Your eyes widened, looking at his flushed face. That's not what you were expecting him to say at all. You stare at his face before smiling, grabbing the keys on the nightstand. "Thank you baby. Let's go"
Isagi gained the courage to look back at you once you had your shorts on before nodding and walking behind you.
But in his head? He took a mental picture of it. Every mark. Every inch. Every line. He loved it, and wanted to see more of it.

🌺 Chigiri Hyoma
Initial Reaction Chigiri had seen stretch marks before, they weren't anything new to him, but he didn't think much of them. They were always in the background of his head. He never thought negatively about them, he had his own scars on his body but he wasn't actively looking for a girl with stretch marks. He wouldn’t call himself well informed either. If anything, he thought they looked kind of cool. Like proof that your body had lived. Still, he never gave them much thought, until he saw them on you.
When he sees them on you You were changing out of your leggings, swapping them for a pair of loose shorts you’d just pulled from the dryer. It was casual, quiet, something you’d done in front of him before. But this time, the light hit you differently. And there they were. Your stretch marks.
And he paused. Not because they surprised him, but because he hadn’t noticed them until now, and suddenly they were all he could see. Not in a bad way. Not at all. He was just caught on the way they curved with your shape, how natural they looked on your skin.
His mouth parted slightly. He blinked, slow.
You didn’t notice at first. But when you finally turned around and caught him staring, your brow arched. "Why are you looking at me like that?”
Chigiri blinked again, startled out of his trance. A soft flush crept into his cheeks.
“Sorry,” he muttered, eyes flicking away for a second before finding you again. “Just got distracted.." That was all he managed.
You rolled your eyes playfully, smoothing down your shorts before grabbing your water bottle. "Cat got your tongue princess?"
His eyes widened as he looked away, brows now furrowed before grabbing his bag, still glancing at you every few seconds. "You know I hate that."
But in his head?
He was filing it away. The way you looked. The way you didn’t hide. And how he suddenly found himself appreciating something he'd barely paid attention to before. Because now? He loved it, and couldn’t wait to see it again.

🐠 Rin Itoshi
Initial Reaction If he was being honest, and Rin rarely is, even with himself, he always pictured himself with a certain kind of girl. Clean lines. Slim frame. No visible marks. It wasn’t about being judgmental. It was just the image in his head. He liked what was neat. Polished. He never thought too deeply about stretch marks. Just figured it wasn’t something he wanted to deal with. Until you.
When he sees them on you You were reaching for your shirt. Just got out of the shower. Still warm, still damp. You turned away from him to grab something from your drawer, and in that moment, he saw them. The stretch marks across your waist, curling over your hips and lower back. He froze.
And for a few seconds, he didn’t know what to do.
It wasn’t disgust. It wasn’t surprise. It was confusion.
Because his brain registered something that went against what he always thought he wanted, but his body didn’t hesitate. His gaze dragged over every line like he was studying them. Not with judgment, but curiosity. Interest. Maybe even something closer to awe. You turned to look at him, towel still tucked under your arms.
“What?” you asked, neutral but cautious.
He didn’t answer right away. He didn’t trust his voice. Then finally, he said, almost flatly, “Come here.”
You frowned a little. “Why?”
“Just... come here.”
So you did.
He reached for you slowly, letting his fingers ghost along your side, then settle on your hip. His thumb brushed the edge of one of the marks, like he was trying to understand it through touch. His expression didn’t change much. But his voice softened, just barely.
“I didn’t know you had these.”
You raised an eyebrow. “Is that a problem?”
“No.” A pause. Then quieter, “I like them.”
You stared at him for a second, unsure if you heard him right. But Rin didn’t look away. Didn’t explain it. Just kept his hand there. And that was the moment you realized he didn’t want perfect anymore. He just wanted you.

🐝 Bachira Meguru
Initial Reaction Stretch marks? Yeah, he’s seen them before, on social media, magazines, and if we are being honest barely in porn. He didn't see them a lot, but he never once thought of them as weird. If anything, he thought they looked cool. If you asked him directly? He’d admit it. He’s into them. Always has been. Something about the lines, the texture, the way they make people look... real. Lowkey a turn on if we are being fr.
He never had a problem voicing how he liked them to whoever asked, it was true after all. And then you came along. and you were the full package.
When he sees them on you You were lying on your stomach, scrolling on your phone, wearing one of his oversized shirts and nothing else but your underwear. The way it bunched up around your hips, the way the light hit your skin, that’s when he noticed them. And wow. His brain stopped working. Not in a respectful boyfriend kind of way. Not entirely. More like… holy shit, I wanna put my hands there. His mouth parted a little. He tilted his head.
“Hey,” he said suddenly, catching your attention.
You glanced back lazily. “Hm?”
“You have stretch marks,” he said, grinning.
You blinked. Cautious. “...Yeah?”
Then he flopped on the bed beside you, chin in his hand, eyes on your thighs. “They’re hot.”
You laughed, rolling your eyes. “You’re just saying that.”
“I’m really not,” he said, voice dropping slightly. “I’m losing my mind over them.” You stared at him for a second.
His smile didn’t drop.
He reached out, fingers trailing along the curve of your hip. Gentle, like he was tracing art.
“You look good like this,” he said. “Like… real good.”
And that was the end of that.
You weren’t embarrassed anymore. Because he looked at you like you’d just become his favorite thing he’d ever seen.
"You gonna let me see the rest of them?"
He asked with his regular smile, but you could see it in his eyes. He wanted to see the rest of the artwork on your body.

🧡 Kunigami Rensuke
Initial Reaction If he was being honest, stretch marks weren’t really something he thought about. Not in a judgmental way, just not something he expected to see due to what the media put out. When he pictured intimacy, he imagined smooth skin, soft lighting, that movie perfect moment. He didn’t even know he had that expectation until it got challenged, and you challenged it without saying a word.
When he sees them on you You were changing, half focused on your hair in the mirror, shirt already off. You reached for a pair of shorts, and when you bent forward just slightly, he saw them. The stretch marks along your thighs, soft and steady across your skin. And for a second, he froze. His mouth parted. His breath caught. Not out of discomfort, but because it was not what he was expecting. And that did something to him.
You turned around and caught his expression, eyes narrowed slightly.
“What?”
Kunigami blinked. Looked away. Ears already turning red. "Nothing,” he muttered, voice low. “You just... I didn’t know you had those.”
You raised an eyebrow, looking down. You were confused. You've seen your stretch marks so many times you didn't even notice them anymore. You had to really look at what your boyfriend was looking at to see what he was referring to. “You mean stretch marks?”
He scratched the back of his neck, sheepish. “Yeah.”
You watched him carefully. “Is that... a problem?”
He looked back at you then. Really looked.
“No,” he said, almost too fast. Then slower, like he was still figuring it out himself, “It’s not a problem. It’s just... I didn’t expect them. But now that I’ve seen them... I kinda—” He swallowed. “—want to see more.”
Your eyes widened slightly.
He stepped closer, gaze flicking down, lingering for just a second.
“They’re... really pretty on you.”
And just like that, the room felt smaller. Warmer. Like maybe he wasn’t as innocent as you thought.

💜 Mikage Reo
Initial Reaction Reo lives in a world that’s all about image. Luxury. Perfection. Airbrushed everything. Even the people around him feel too carefully edited sometimes. So no, stretch marks weren’t something he thought about, borderline even knew about. Because they didn’t show up in the spaces he usually moved through. (Other than Nagi occasionally mentioning them) But the truth? He wouldn’t have cared either way. Until you. And now? Yeah, it’s a little bit of a thing for him.
When he sees them on you You were getting dressed after a shower, towel tucked under your arms, skin still warm. You reached for your lotion, one leg propped on the edge of the bed. And that’s when he saw them. Across your thighs. Up your sides. Clear. Unapologetic. He froze. Then blinked. Then he tilted his head a little. Something about the way they caught the light. The way they curved with your body. He bit the inside of his cheek, trying not to stare.
You looked up at him through the mirror, catching the shift in his expression. “What?” you asked, half laughing.
He blinked again, eyes flicking up to yours. Then he smiled. Slow. A little sheepish.
“Nothing,” he said. “You just look... good.”
You narrowed your eyes playfully. “That’s it?”
He hesitated. Then stood, crossing the room in a few easy steps. When he reached you, his hands found your waist. His thumbs brushed over the marks without hesitation. “I didn’t know that’d be something I liked,” he said softly, almost to himself. You looked at him. He looked at your skin like it was something made to be seen.
“Now I won't be able to stop thinking about them,” he added. And he meant it.

🤍 Nagi Seishiro
Initial Reaction Stretch marks weren’t on his radar. At all. He’s not the kind of guy who scrolls through curated bodies online. Sure he sees bodies all the time, models, beaches, porn. Doesn’t care about filters or trends or what’s “ideal.” He’s barely paying attention to anything that doesn’t directly affect his comfort. He always thought the girls online seemed so clearly fake and edited. So the few times he did see stretch marks, it caught his eye.
When he sees them on you You were lying across the bed, phone in hand, half asleep. His shirt rode up just a little, and your shorts sat low on your hips. That’s when he saw them. Stretch marks, soft and natural, curved with your shape like they belonged there. His eyes lingered longer than he realized. His brain went still for a second. It wasn’t shock. It caught his attention.
“Hey,” he muttered, voice low.
You glanced over, yawning. “What?”
He didn’t answer right away. He rolled over next to you, hand sliding lazily to your hip, fingers brushing over the lines.
“Don’t cover these,” he said, so casually it made your heart trip.
You blinked. “.. Okay."
“Good,” he mumbled. “I like them.”
You laughed, a little caught off guard. “Really?”
He nodded into the pillow. “Yeah. They look good.”
Then he closed his eyes again like it was no big deal. But his hand stayed there. Fingers tracing those same lines like they belonged to him. And in his head? They kind of did.
