Zoro can't shake the feeling.
Even after Robin slips away, leaving him in the low light of his room, the weight in his chest lingers. Her touch, her words—they hang in the air like mist, clinging to him long after she's gone. He leans forward, elbows on his knees, gripping his forehead with both hands, trying to steady his breath. He's faced death a thousand times. Walked through battlefields, swords flashing and blood running thick, and never once flinched. But this? This gnawing, heavy tenderness tearing him apart whenever he thinks of her—that's something else. The quiet of the room presses in on him, thick like the air before a storm. He needs to move. Sitting still is worse than any pain he's ever fought through. His muscles twitch, restless for action, for something to distract him from the mess in his head. He stands abruptly, heading for the door. Training. He'll exhaust himself until his body is too wrecked to feel anything else. But just as his hand reaches the handle, the door creaks open. Luffy stands in the doorway, grinning, panting slightly as if he's just run across the ship.
"Zoro," his voice is laced with concern. "You need to come with me."
Zoro's heart pounds harder the closer they get to the deck, a tight knot forming in his chest. He doesn't want to deal with whatever's waiting up there. Not right now. When they reach the deck, the sea breeze hits him, and for a second, everything feels normal. The gentle roll of the ship, the quiet hum of the ocean. But then he sees her. Robin is standing at the edge of the deck, facing the sea. Her back is to them, her hair shifting slightly in the wind, but there's something wrong—something off. Her usual calm, collected posture is gone, replaced by a rigid tension in her shoulders. Her hands, which are always so steady, are clenched into tight fists at her sides. A cold chill runs down Zoro's spine.
"What's happening?" Nami's voice trembles from somewhere nearby, but Zoro barely registers it. His focus is locked on Robin. Something's wrong. The air around her feels thick, almost charged, and Zoro's mind flashes back to the ritual—the way the power had wrapped around them, cold and hungry. It's the same. That same unnatural weight pressing down. Without thinking, Zoro takes a step forward, but Luffy's hand shoots out, grabbing his wrist.
"Wait."
Zoro yanks his arm free, glaring. "What the hell, Luffy?"
Luffy doesn't let go. Zoro's jaw tightens, every instinct telling him to ignore Luffy and go to her. But then Robin moves—slowly, deliberately. She turns around, and Zoro's breath catches. Her eyes. They're not hers. Not entirely. The calm, sharp intelligence that defines her is still there, but it's layered with something darker, something that shouldn't be. A flicker of faint red glows beneath her irises, just like the sigil. Zoro's breath stills in his chest. That faint red glow in Robin's eyes—it's the same as the markings from the ritual. The same power he had felt coursing through him, binding them together in ways he hadn't fully understood. And now she's looking at him, but it's as if someone else is staring through her.
Robin blinks, her expression shifting. Confusion crosses her face, followed by a moment of fear that Zoro has never seen on her before. Her hands loosen from their fists, her fingers twitching like she's fighting something unseen. Then, without warning, her eyes widen, and Zoro feels it.
A surge—like a wave crashing into him, slamming him backward. His vision blurs, and suddenly he's not on the deck anymore.
Zoro's back in the dojo, the familiar scent of sweat and worn wood heavy in the air. His younger self is there, training under the relentless sun, the weight of two swords in his hands, sweat dripping down his face. There's Kuina, her smirk sharp as ever, daring him to attack.
"Zoro?"
Robin's voice cuts through the memory, startling him. She's standing beside him, fully grown and completely out of place in this snapshot of his past.
She looks around, eyes wide with surprise, but the fear is gone, replaced by a quiet curiosity. Zoro's throat tightens. He doesn't understand it either, but he knows this place. It's his past, his memories. They've somehow slipped into his world now, just like he'd fallen into hers during the ritual. He doesn't answer, too stunned by the sight of her here. Two entirely different realities of his are colliding, and it's triggering – almost nauseating. Instead, he watches as she steps closer, her eyes scanning the scene in front of them—the young Zoro clashing with Kuina, the ferocity of their sparring, the frustration in his eyes when he loses yet again. Robin flinches when Kuina slams Zoro to the ground, her wooden sword pressed against his throat. There's a glint of sympathy in her expression, and Zoro feels a wave of discomfort. He doesn't want her to see this—to see his failures, his struggles.
"This is…" Robin trails off, glancing at him, realization dawning in her eyes. "This is your memory."
Robin watches young Zoro, her gaze sharpening as the scene unfolds before her. At first, it's the fierce, unrelenting determination in his eyes that holds her attention. She knows that look all too well—the drive to push through pain, to overcome, to never be weak again. But there's something else. Something deeper. As young Zoro pushes himself up from the floor, wiping the blood from his mouth with the back of his hand, his eyes flicker to Kuina. The tension in the air is palpable, but it's not just because of the rivalry between them. Robin can feel it—the undercurrent of something more. The way Zoro looks at Kuina isn't just the gaze of a boy determined to surpass his rival; it's protective, fierce in a way that feels almost intimate.
Robin's breath hitches slightly, and her fingers curl at her sides. She hadn't expected this. She had always seen Zoro as someone too driven, too focused to ever let anyone close, not in this way. And yet, here it is.
Young Zoro squares his shoulders, his gaze locked on Kuina as she readies her stance for another bout. There's a fire in his eyes, one that speaks of more than just ambition—it's a desire to protect, to prove himself worthy of standing at her side. His lips part, as though he's about to say something, but the words catch in his throat, swallowed by the intensity of the moment.
Robin feels a strange pang in her chest as she watches the exchange, the unspoken connection between them. Zoro's frustration with himself is not just about losing—it's about failing Kuina. Failing the one person who's ever pushed him, the one person he's let himself feel something for.
Zoro stands beside her, rigid, his shoulders tight as he watches his younger self. He doesn't say anything, but she can feel the tension radiating off him. It's not anger—not entirely. It's something else. Robin turns her gaze to him, searching his face. She's rarely seen him like this—open, vulnerable in a way that feels raw. The tough exterior he usually carries seems to crack under the weight of the memory, exposing something deeper, something that perhaps even Zoro himself hasn't fully acknowledged.
"You loved her," Robin almost says: an accusation. But she doesn't.
They watch in silence as young Zoro picks himself up, shaking with frustration and the raw determination that fueled every fiber of his being back then. The memory fades just as quickly as it came, and the scene shifts again—this time to a different place, a different moment.
As the scene shifts around them, the memory dissolves, and the familiar creak of the Thousand Sunny replaces the dojo's faint echoes. Zoro and Robin stand in the present once again, the weight of what they've just witnessed clinging to the air between them. The sun sets low on the horizon, casting long shadows over the deck, but there's an uneasiness that has settled, thick and heavy, between them. Robin steps back, her expression unreadable. She tries to shake the lingering emotions from Zoro's memory, but they gnaw at her. The way he looked at Kuina—the intensity of it—keeps replaying in her mind, a spark of something unfamiliar settling deep in her chest.
Zoro, oblivious to the storm brewing inside her, runs a hand through his hair, trying to ground himself after the flood of emotions. He's not one to dwell on feelings, not like this, but something about being pulled into his own memories with Robin by his side has left him off-balance. The tenderness he's always felt toward Robin remains, but now it feels entangled with everything he's just shared with her—things he didn't even realize he still carried. His feelings for Kuina, his failure to protect her, and the promise that's driven him since. It's all bleeding into the present.
Robin turns toward the ship's railing, resting her hands on the wood as the sea breeze brushes against her skin. The coldness of the wind feels welcome, a distraction from the emotions swirling inside her. But no matter how hard she tries to focus on the rhythmic waves beneath them, her mind drifts back to Kuina, to the connection she saw between her and Zoro. It's foolish, she tells herself. Kuina was someone Zoro cared about deeply, someone he lost. She feels a pang of something close to resentment. Jealousy, even. It catches her off guard, like a sudden punch to the gut. She doesn't have the answer, but the bitterness creeping into her chest is undeniable. Robin prides herself on her control—her ability to stay calm, analytical, to not let emotions dictate her actions. But this… this feels different. Unfamiliar. It feels raw.
"Alright?" Zoro's voice breaks through her thoughts, rough but soft in a way that she knows is meant for her alone.
"I'm fine," she says too quickly, her voice quieter than she intends. She doesn't look at him. She can't. The strange heat beneath her skin, the unfamiliar frustration—she needs time to process it, to bury it before it becomes something else. Something she's not ready to confront.
Zoro frowns, sensing that something is off. Normally, Robin's voice has a calm, steady quality to it, no matter the situation. But now, there's something clipped in her tone, something distant. Robin lets out a slow breath, still staring at the sea. Words have never been his strong suit, and right now, he's feeling the weight of that inadequacy more than ever. He doesn't know how to reach her when she closes herself off like this, and it's infuriating. But he's learned to let her have her space when she needs it.
Finally, he grunts, turning his back to the railing.
Robin's grip on the railing tightens. She can feel the tension radiating off him, but she keeps her focus on the horizon, on the endless stretch of water that feels as cold and vast as the growing distance between them. She should say something to close the gap, to offer him the understanding she knows he's searching for. After everything. But she can't.
"I'll… leave you to think," he finally mutters, turning to walk toward the training room. His voice is rough, edged with an uncertainty that isn't like him at all. Robin's shoulders tense as she watches him leave, her gaze flicking toward him just as he disappears through the door. The space between them feels like an ocean now, vast and unreachable, and she doesn't know how to cross it. Not when she barely understands why it's there in the first place. But that bitterness in her chest—she knows it won't be easy to push aside. Not when the image of Kuina and Zoro keeps flickering behind her eyes, a reminder of something she hadn't realized she wanted. Something she's afraid of wanting. And for the first time in a long while, Robin feels vulnerable in a way that has nothing to do with her past. It's far more personal.
Later that night, the ship falls into a quiet lull as the rest of the crew drifts off to sleep. The Thousand Sunny is still, save for the soft creaking of the wood and the gentle slosh of waves against the hull. Inside the women's quarters, the dim glow of a lantern casts long shadows across the walls. Robin sits on her hammock, knees drawn slightly to her chest, her mind spinning as it has been for hours.
Nami is lying on her own hammock, facing the opposite wall, but Robin knows she's not asleep. The navigator has been unusually quiet all evening, glancing at her in that way she does when something's clearly wrong but waiting for Robin to speak first. It's almost comforting, Nami's silent understanding, but tonight the weight of everything feels different. The memories, the distance between her and Zoro—it all festers beneath the surface, churning in a way that unsettles her deeply.
Robin sighs softly, running her fingers through her hair as she stares at the ceiling. Her mind flashes back to that moment with Zoro on the deck earlier. His raw, unspoken emotions, the quiet hurt behind his eyes—she can't stop thinking about it. And then, of course, there's Kuina.
Kuina.
Robin clenches her fists in her lap, frustration bubbling beneath her calm exterior. It's irrational—she knows it. She's not one to dwell on matters of the heart, and she certainly shouldn't feel jealousy over someone long gone. But there's something about the way Zoro looked at Kuina in his memory, that fierce protectiveness and loyalty, that makes Robin feel… vulnerable. And it bothers her.
"You've been quiet," Nami finally speaks, breaking the silence. Her voice is soft, careful, but laced with curiosity. She rolls over to face Robin, propping her head up with her hand. "More than usual."
Robin pauses, her fingers tracing the edge of her blanket. She considers brushing it off—deflecting with a half-smile and a vague answer like she usually does. But she can't find it in herself to do that tonight. Not with Nami.
"It's nothing, really," Robin murmurs, though the lie sounds weak even to her own ears.
Nami raises an eyebrow, her expression both knowing and patient. "Right. And that 'nothing' has been bothering you all day."
Robin closes her eyes briefly, exhaling.
"It's just… something I experienced with Zoro," she admits, keeping her voice low. "It's hard to explain."
Nami's brows furrow slightly. "Something with Zoro? What happened?"
Robin shifts, the memory of Kuina's face flickering in her mind again.
"We—" she hesitates, unsure how to describe it. "We shared some memories. His memories."
Nami sits up a little more, interest piqued. "You mean like what happened with you before?"
Robin nods. "Yes, but this time it was his past. His memories of Kuina."
The name comes out before she can stop it, and the bitterness she's been holding in all evening seeps into her voice.
Nami's eyes widen slightly at the name, recognition flickering across her face.
"Kuina…" she echoes, her voice soft with understanding. "Zoro's childhood friend."
Robin doesn't need to confirm it; Nami knows the story, as do all of the Straw Hats. Zoro's ambition, his bond with Kuina, the promise they made to each other—it's all part of his past, the foundation of the swordsman he is today. But for Robin, seeing it firsthand, feeling it through his eyes, it's different. It's intimate in a way she hadn't anticipated, and it's left her shaken.
"He loved her," Robin says, quieter now. "I could see it. Feel it."
Her gaze drops to her hands. "It was more than just admiration or rivalry. There was… affection there. Real affection."
Nami is silent for a moment, processing this. Then she speaks gently, "And that bothers you?"
Robin's jaw tightens. "It shouldn't."
"But it does."
Robin exhales sharply, the admission coming out in a rush. "Yes. It does."
Nami watches her for a moment, her expression thoughtful. "Robin, it's okay to feel this way. You don't have to justify it or make it go away just because it doesn't make sense."
Robin shakes her head.
"It's not about that. It's just—" She pauses, struggling to find the words. "It's complicated. Zoro and I… we're not—"
"You don't have to be anything," Nami interrupts softly. "Feelings don't always need labels. Sometimes they just are."
Robin falls silent, Nami's words sinking in. There's truth in them, but it doesn't make the weight in her chest any easier to bear. She doesn't want to feel this way, doesn't want to be consumed by jealousy over a memory of someone who's long gone. But that doesn't change the fact that she does feel it.
Nami watches her closely, then leans back on her hammock with a sigh.
"For what it's worth, I don't think Zoro's even aware of what you're feeling. He's not exactly the most emotionally in-tune person on the planet."
Robin allows a small, humorless smile to tug at her lips. "No. He's not."
"But he cares about you, Robin. In his own way." Nami shrugs. "Maybe that's what's making all of this so confusing."
Robin doesn't respond, her thoughts drifting back to the memory of Kuina and Zoro. The way Zoro looked at her, the fierce loyalty in his eyes—it's not something Robin has seen in him before, at least not directed toward her. And that's what unsettles her the most. The idea that maybe she wants that look. Maybe she wants to be the one Zoro protects, the one he feels something more for.
And that thought terrifies her.
The quiet stretches between them again, both women lost in their own thoughts. The ship sways gently with the sea, but inside the women's quarters, the tension lingers, unspoken and heavy.
Eventually, Nami breaks the silence.
"Get some rest, Robin," she says softly. "Whatever this is… you'll figure it out."
Robin nods absently, though rest feels like the farthest thing from her mind. She lies back on her hammock, staring up at the ceiling, but sleep doesn't come.
The next morning, the ship hums with life. Sunlight filters through the small window of Robin's quarters, the soft sound of waves against the hull a comforting background to the stirrings on the Thousand Sunny. She lies in bed longer than usual, her mind clouded with fragments of dreams she can't quite piece together—images of Kuina, of Zoro, of the closeness she'd never expected to feel toward him. She sighs and stretches, the stiffness in her muscles betraying the restlessness of the night before. By the time she pulls herself from the warmth of her bed, she knows the rest of the crew must already be up. The smell of something rich and savory wafts through the hall as she steps out of her quarters, the sound of Luffy's voice carrying from the galley, excited and loud and familiar.
As she walks down the corridor, Robin moves with her usual grace, but her thoughts are anything but steady. The strange sensation of resentment that had bubbled up last night still clings to her, a gnawing discomfort she can't quite make sense of. The memory of Zoro's connection to Kuina plays on a loop in her mind, and with it, an unfamiliar feeling of jealousy that unsettles her. She pushes it down, telling herself it's irrational. But it lingers.
Just as she rounds the corner, her thoughts distracted, she collides into something—or rather, someone. Robin gasps softly, her balance faltering for just a moment before strong hands steady her. She looks up, and her breath catches in her throat.
Zoro.
He stands there, his chest practically against her face, the warmth of his body radiating through the thin fabric of his shirt. His grip on her arm is firm but not rough, his eyes widening for a split second before his usual mask of stoicism slips back into place. But she can feel it—the subtle tension in his body, the way his fingers linger just a moment too long before he lets go.
For a brief second, they're both frozen, standing too close, too aware of each other.
"Sorry," Robin murmurs, her voice softer than she intended, her heart pounding harder than it should be.
Zoro grunts in response, his jaw tight, his eyes flicking away from hers.
"No, it's… fine," he mutters, almost awkwardly. He steps back, giving her space, though the air between them still feels heavy.
Robin blinks, her pulse still racing from the sudden proximity, the heat of him still lingering in the space they'd shared. She hadn't realized how tall he is compared to her, how broad his shoulders are. For someone who rarely thinks about such things, the awareness of his physicality leaves her flustered.
For a moment, she wonders if he's thinking about Kuina—about what she saw in his memories. The tension between them isn't just from this morning. There's something deeper, something neither of them wants to confront just yet.
"I was just heading to the galley," she says.
"Yeah. You should hurry before Luffy inhales everything," Zoro mutters, his voice low and rough as always, but there's an unfamiliar edge to it. He looks away, shoving his hands into his pockets in a gesture that feels uncharacteristically uncertain.
Robin's eyes linger on him for a moment longer, trying to read what's just beneath the surface. But Zoro isn't one to show his emotions easily, and she knows better than to push him. Not yet, at least.
"I'll see you in there, then," she says with a small, forced smile.
Zoro nods once, then turns on his heel, walking down the hallway toward the training room, his footsteps heavy against the deck.
Robin watches him go, her gaze trailing after him until he's out of sight. She exhales slowly, her heart still unsettled, her mind replaying the moment they'd bumped into each other. The strange, flustered feeling gnaws at her, but she doesn't have time to dwell on it now. The crew is waiting, and she can't afford to let her emotions cloud her judgment. The smell of food hits her as soon as she steps inside. Luffy is already at the table, practically vibrating with excitement as Sanji sets out plates of steaming pancakes, eggs, and freshly sliced fruit. The rest of the crew is seated as well—Usopp and Chopper chatting animatedly about their next adventure, Brook humming a tune as he tunes his violin, and Nami sipping her coffee with a look of pure contentment.
"Robin! You're late!" Luffy calls out. "Hurry up, or there won't be anything left!"
The crew dives into breakfast, the chatter light and easy, the clinking of forks and knives filling the air as they talk about the day ahead and the approaching island of Rikana. Luffy, of course, is already planning his grand feast for their arrival, while Franky talks about the repairs he wants to do on the ship.
Robin listens, her smile soft, but her mind keeps drifting.
