The acrid scent of blood and burnt wood hung heavy in the air as M/n knelt by the crumpled body. The boy was a mess—his dark hair matted with dirt and blood, his skin bruised and pale.
One leg was crushed beneath the rubble, the jagged bone peaking out of the skin of whatever remained. The fleshy tethers barely holding together as the wound sluggishly oozed blood.
It was clear to M/n that he wouldn’t be able to save the leg.
The boy on the other hand barely clinging to life yet—he was still conscious. He was mouthing words that M/n couldn’t make out but they sounded like names–Rin, Kakashi, Sensei.
M/n wondered who these people were to the boy as he stabilized him and whisked him away.
══✿══╡°˖✧✿✧˖°╞══✿══
His body was betraying him—his ears rang, breathing felt like knives, and his body oddly enough, felt numb. Is this what it felt like to die?
No—not yet.
He promised them that he would catch up, that he would surpass Kakashi, so he can’t give up. But his body is betraying him—giving up.
His vision is becoming cloudy, when suddenly he feels relief. He sees the figure of a person and he can’t help but think that Rin and Kakashi had come back for him— they even brought sensei!
With that thought he completely falls into unconsciousness.
══✿══╡°˖✧✿✧˖°╞══✿══
When he awoke, it wasn’t the cold of death or the warmth of his team by his bedside that greeted him. Instead, it was the subtle chill, that flowed from a nearby open window.
A flickering fire cast shadows on the walls of the small cabin, its light catching on the smooth walls. He tried to sit up, but pain shot up through his chest and down to his leg, forcing him back down with a sharp gasp.
“Don’t move,” a voice said, calm but firm.
Obito’s gaze snapped to the source. A man knelt by his side, his face partially hidden by the shadows. His presence was commanding, the kind that demanded attention without needing to ask for it.
The man’s hands moved with practiced ease as he adjusted the bandages around Obito’s chest, his touch surprisingly gentle.
“You’re lucky I found you when I did,” the man continued, his tone almost conversational. “A few more minutes, and you’d have bled out in the mud. Hell of a way to go.”
“Who… who are you?” Obito rasped, his throat dry and voice barely audible.
The man paused, tilting a cup of cool water to Obito’s lips— he opened his mouth before he could even think of checking for poison, the water soothed his achingly dry throat.
His dark eyes met Obito’s as he put down the cup on a nearby dresser. There was something unreadable in his gaze, something that made Obito’s stomach twist.
“Just someone passing through,” he said after a moment, his lips curving into a faint smile. “Call me M/n.”
“M/n…” Obito repeated, his voice cracking.
“Rest now,” M/n said, placing a firm hand on his shoulder when Obito tried to push himself up again. “You’re in no shape to do anything reckless. I’ve already stitched up that leg of yours, but if you move wrong, you’ll tear it open again.”
Obito’s gaze flicked to his leg, and his breath hitched at the sight of the crude splint and thick bandages wrapped around the stump where his lower leg used to be, it was gone from the mid-thigh. Panic clawed at his chest, his mind spinning as he remembered the boulder, the pain, the crushing weight that had pinned him—
“Hey.” M/n’s voice cut through the spiral, his hand gripping Obito’s shoulder more firmly. “Breathe. You’re alive. That’s all that matters right now.”
The words, though simple, anchored him. He inhaled shakily, forcing his mind to quiet, and nodded.
══✿══╡°˖✧✿✧˖°╞══✿══
Over the next few weeks, M/n tended to Obito’s injuries with a patience that bordered on tenderness.
He hunted, cooked, and even shared what little he had without complaint, though his sharp, calculating eyes always seemed to watch Obito too closely.
“You’re strong,” M/n said one evening, his voice breaking the quiet. He was crouched by a fire outside of the cabin, sharpening a blade as the light danced across his features. “Most people wouldn’t have survived what happened to you. But you did.”
Obito glanced at him, his expression guarded. He was still wary of this stranger, but he couldn’t deny that M/n had saved him. He owed him his life.
“I had to,” Obito muttered, his gaze falling to the fire. “Rin and Kakashi… they need me.”
M/n’s hand stilled, his blade catching the light as he looked at Obito. “Do they?”
Obito frowned, confusion flickering across his face. “Of course they do. They’re my teammates.”
M/n hummed thoughtfully, his gaze returning to the blade in his hands. “And where are they now?”
The question hit harder than Obito wanted to admit. He clenched his fists, his nails digging into his palms as he looked away. “They probably think I’m dead.”
“Maybe,” M/n said softly, his voice almost pitying. “Or maybe they left you behind.”
Obito’s head snapped toward him, anger flashing in his dark eyes. “They wouldn’t—”
M/n raised a hand, cutting him off. “Relax. I’m not saying it’s true. I’m just saying you shouldn’t expect too much from people.”
His words lingered, settling over Obito like a shadow.
══✿══╡°˖✧✿✧˖°╞══✿══
The day Obito could walk again, he ran. His leg ached with every step, the crude prosthetic M/n had fashioned was digging into his skin—which to M/n’s credit said he would make a better one, one that would connect to his chakra and fit better. But he didn’t care for that right now—he had to see Rin, had to let Kakashi know he was alive.
But when he found them, the sight that greeted him shattered what little was left of him.
Rin’s body crumpled beneath Kakashi’s Chidori, blood staining the ground as her lifeless eyes stared into nothingness. Kakashi fell to his knees beside her, his expression twisted with grief, but all Obito could see was the blood on his hands.
Something inside him snapped. He wanted to scream, to cry, to kill, but his body refused to move. The world blurred around him, and by the time he stumbled back to the cabin, his breath was ragged and his vision was swimming.
M/n was waiting for him.
“Obito,” he said, rising to his feet as the younger shinobi collapsed into his arms. “What happened?”
“They… she…” Obito’s voice broke as he buried his face in M/n’s chest, his fists clinging to the man’s shirt like a lifeline.
M/n’s arms wrapped around him, his grip firm but not unkind. “Shh,” he murmured, his hand smoothing over Obito’s hair. “You don’t have to say anything. I’m here.”
Obito’s shoulders shook as he wept, the grief and anger pouring out of him in waves. And through it all, M/n held him, his gaze dark and unreadable.
══✿══╡°˖✧✿✧˖°╞══✿══
The days after Obito returned to M/n were a blur. He didn’t speak of what he saw—didn’t have the words to describe how Kakashi’s Chidori had ripped through Rin’s chest, how her blood had painted the earth. When M/n asked, his response was always the same: silence.
But M/n didn’t press him. He gave Obito space, kept his voice soft, his touch gentle, and waited.
It was on the seventh night, after another fitful sleep, that Obito finally broke.
The fire crackled between them, casting dancing shadows across the cabin walls. Obito sat hunched over, his face buried in his hands, his entire frame trembling with barely contained emotion.
“She’s dead,” he whispered finally, the words clawing their way out of his throat. “Rin’s dead. He… Kakashi… he killed her.”
M/n’s gaze sharpened, but his expression remained calm. He set down the blade he’d been sharpening and crossed the room to kneel in front of Obito.
“I see,” M/n said quietly, placing a firm hand on Obito’s shoulder. “So now you know.”
Obito’s bloodshot eyes lifted to meet M/n’s, confusion flickering across his face. “Know what?”
“That people betray you,” M/n said simply, his tone laced with pity. “The ones you love the most—they always do. Rin, Kakashi, your sensei—they all abandoned you when you needed them most. And now look at you.”
“That’s not true,” Obito muttered weakly, though the weight of M/n’s words pressed against him like a vice. “Rin didn’t… she didn’t abandon me.”
“Didn’t she?” M/n’s hand slid to the back of Obito’s neck, squeezing just enough to draw his attention fully. “You saw what she did, Obito. She chose to die. And Kakashi let her.”
“She didn’t want—”
“Then why didn’t she fight? Why didn’t she try to stay alive for you?” M/n’s voice hardened, though he kept his expression calm. “Because she didn’t believe in you, Obito. They didn’t believe in you. But I do.”
The words hung heavy in the air, sinking into the cracks of Obito’s broken resolve.
“I pulled you out of that wreckage. I saved you when no one else cared. Not Rin, not Kakashi, not anyone.” M/n leaned closer, his grip tightening slightly. “You only have me now. And I will never leave you. But you have to let go of them. Let go of the people who hurt you.”
Obito’s shoulders shook, his breath hitching as the first tears fell. And when M/n pulled him into his arms, cradling him like a fragile thing, he didn’t resist.
══✿══╡°˖✧✿✧˖°╞══✿══
It started as training.
At first, M/n’s methods seemed harsh but reasonable—he drilled Obito relentlessly, making him push past exhaustion, teaching him how to move with his new prosthetic.
The pain in his missing leg was unbearable some days, but M/n was always there, his voice unwavering: "Your pain is a gift. Learn from it."
Obito tried. He really did. But the grief still gnawed at him, slowing his movements, making him hesitate. He could still see Rin’s face, still hear Kakashi’s voice calling her name.
M/n saw it. He always saw it.
One evening, after Obito collapsed mid-exercise, chest heaving and body trembling, M/n’s patience snapped.
"You’re weak," M/n’s voice was cold as steel. "That’s why you couldn’t save her. That’s why they left you."
Obito flinched, his fingers clenching in the dirt beneath him. “I’m trying,” he muttered, voice barely above a whisper.
"Not hard enough."
The kick came fast—M/n’s boot slammed into Obito’s ribs, sending him sprawling onto the ground. The air fled from his lungs in a choked gasp, pain searing through his body like fire. He curled in on himself instinctively, clutching his side.
His mind screamed at him to fight back, to retaliate—but he didn’t. He couldn’t.
M/n crouched down beside him, fingers gripping Obito’s chin, forcing his face upward. His dark eyes were unreadable, but there was something expectant in them. Waiting.
“Look at me,” M/n ordered.
Obito’s vision was blurred, pain radiating through his skull, but he obeyed.
The moment their gazes locked, a sharp snap rang through his head—a shift, a pull, like something deep inside him had finally woken up.
M/n’s expression changed slightly, his fingers tightening just a little. "Oh?"
Confused, Obito blinked, the world suddenly too sharp, too vivid, too clear. The flickering fire behind M/n cast shifting shadows across his face, the individual strands of his hair distinct in a way that shouldn’t be possible.
His breath hitched.
"The Sharingan," M/n murmured, a slow smirk curling his lips. "Three tomoe."
Obito didn’t understand at first. He blinked again, the clarity still there, still unnatural—and then realization hit him like a blade to the chest.
His Sharingan had fully matured.
The pain, the anger, the agony of loss—it had pushed him to this moment.
M/n had pushed him to this moment.
Obito shuddered, his lips parting as if to speak, but nothing came out. He felt sick, like something inside him had shifted permanently.
M/n’s thumb brushed over his split lip, smearing the blood there as if admiring it. "Now, do you see?"
Obito swallowed hard, his new vision locking onto M/n’s eyes.
"Pain makes you stronger," M/n murmured, almost reverently. He released Obito’s chin but didn’t move away. "You should be thanking me."
And Obito did.
══✿══╡°˖✧✿✧˖°╞══✿══
M/n hadn’t spoken in a while.
The silence stretched between them, thick and suffocating. The only sound was the dull drip, drip of blood hitting the wooden floor. Obito’s blood.
He knelt, panting, sweat and crimson streaking his face. His body ached, the dull throb in his ribs reminding him of the blows he had taken. His Sharingan still spun wildly, his breath sharp and uneven.
He had failed. Again.
M/n leaned back against the wooden table, arms crossed. He was watching—always watching—but his expression gave away nothing.
Obito’s stomach twisted. He had learned to recognize that look.
"Disappointing," M/n finally murmured, shaking his head.
Shame burned through Obito’s chest like acid. His fingers twitched where they rested against the floor, curling into fists.
Not enough.
He was never enough.
“I…” Obito swallowed thickly. “I’ll do better.”
M/n exhaled through his nose, unimpressed. “Will you?”
“Yes.” His voice was desperate now, raw with something frantic. He lifted his head, looking up at M/n with pleading, bloodshot eyes. “Tell me what to do. I’ll do anything.”
M/n tilted his head slightly, as if considering it. Then, after a long moment, he moved.
He crouched in front of Obito, reaching out. His fingers caught Obito’s chin, tilting his face up fully. The touch was softer than it should have been, considering the pain he had just inflicted.
"You still hesitate," M/n said quietly, his thumb grazing the sharp edge of Obito’s jaw.
Obito shivered beneath the touch, not out of fear—but something else.
M/n’s voice dropped lower, his words slow, deliberate. “You hold back because you’re still clinging to them.”
Obito's breath hitched.
Them.
Kakashi. Rin. Sensei. The ghosts of his past still clawed at him, whispering in the back of his mind.
He squeezed his eyes shut. He wanted to drown them out.
“I don’t—” he started, but M/n’s grip on his jaw tightened just enough to stop him.
“Lying doesn’t suit you, Obito.”
Obito opened his mouth—to argue, to deny—but the words died before they could form.
Because M/n was right.
There was still a part of him that ached when he thought of Rin’s smile. A part of him that still saw Kakashi standing over her body in his nightmares.
And M/n had no patience for hesitation.
A sharp sting lashed across his cheek—fast, precise, controlled. Obito’s head snapped to the side from the impact, a choked gasp escaping him.
M/n hadn’t hit him hard. Just enough to prove a point.
“You need to let them go,” M/n murmured, his hand cupping the cheek he had just struck. His touch was warm, careful, fingers brushing soothingly over the red mark.
Obito’s breath stuttered.
The contrast—the sharp bite of pain followed by this—it left him reeling. His mind struggled to reconcile the two, to make sense of it.
But M/n made it easy.
M/n was always there, guiding him, grounding him.
"Do you trust me?" M/n asked, voice barely above a whisper.
Obito nodded, without hesitation. "Yes."
M/n’s fingers trailed down, pressing against the frantic pulse at Obito’s throat. He smiled, satisfied.
"Then prove it."
Obito blinked. "How?"
M/n leaned in, his lips almost brushing against Obito’s ear. "You know how."
And he did.
Burn it all.
Konoha. The village that took everything from him. The village that let Rin die. The village that would never accept him now.
Obito trembled. The hesitation was there—a flicker, a ghost of something old and useless.
Then M/n’s fingers curled around the back of his neck, holding him steady. The touch was possessive, grounding.
"You belong to me, Obito. And I take care of what’s mine."
Something in him snapped.
Rin was dead. Kakashi had left him. Konoha had abandoned him.
M/n was the only one who had stayed.
He exhaled shakily, feeling the last pieces of his past fall away.
"You’re right." His voice was different now—colder. Certain.
M/n grinned. "Good boy."
Obito let out a shuddering breath. And for the first time in his life—he felt free.
══✿══╡°˖✧✿✧˖°╞══✿══
Obito was on his hands and knees, his face pressed against the sheets, breath ragged, body trembling. His arms ached from holding himself up, but he didn’t dare collapse—not when M/n’s grip was so tight on his hips, bruising, possessive.
M/n was taking him apart.
Splitting him open. Stretching him too wide.
Each thrust was deep, unforgiving, his thick cock slamming into Obito’s abused hole, making his vision blur. The wet sounds of skin against skin filled the dimly lit cabin, mixed with Obito’s shaky moans and M/n’s amused chuckles and groans.
"Fuck, Obito," M/n groaned, dragging his nails down Obito’s back, leaving red lines behind. "You’re taking me so well."
Obito whimpered, his fingers clutching desperately at the sheets. His entire body was burning, a mix of lingering pain from training, exhaustion, and the unbearable pleasure coiling tight in his gut.
He shouldn’t love this.
He shouldn’t crave it.
But M/n had made him need it.
"M-M/n—" Obito gasped, his voice cracking as M/n suddenly thrust deeper, grinding against his sweet spot. His back arched sharply, his body betraying him, his walls squeezing around M/n’s thick length.
"What?" M/n taunted, fisting a hand in Obito’s sweat-damp hair, yanking his head back. He tilted Obito’s face just enough to see the tears clinging to his lashes. His smirk widened. "You crying for me?"
Obito bit his lip, choking down a whimper. He was so full, so overstimulated, so wrecked. His thighs shook from strain, but he didn’t want M/n to stop.
He needed it.
"Please—"
M/n’s grip tightened in his hair, forcing his head back further. His breath was hot against Obito’s ear, sending shivers down his spine.
"Please, what?"
Obito’s pride had long since shattered.
He didn’t care if he sounded desperate.
He didn’t care if he had to beg.
"Please fuck me harder—"
M/n groaned, slamming his hips forward in a bruising thrust. Obito let out a broken cry, his back arching beautifully beneath him.
"That’s more like it," M/n growled, setting a ruthless pace. Each thrust knocked the air out of Obito’s lungs, reducing him to whimpers and choked moans.
M/n was ruining him.
Breaking him in every way possible.
Obito’s dick dripped precum onto the sheets, untouched, twitching with every deep, brutal stroke into his puffy hole. He was so close, his entire body trembling, but M/n hadn’t given him permission yet.
"You wanna cum, don’t you?" M/n murmured, dragging his tongue along the shell of Obito’s ear.
Obito nodded frantically, his sore walls fluttering around M/n’s cock, sucking him in deeper.
"Then beg."
Obito didn’t hesitate.
"Please—fuck, please let me cum—"
M/n chuckled, his thrusts slowing, teasing. "So obedient now. What happened to all that defiance?"
Obito’s face flushed darker.
He was too far gone to fight back.
He was too addicted to M/n’s touch, to his praise, to the sharp edge of his cruelty.
"M/n—" he whimpered. "Please—need it, please—"
M/n hummed, pleased. His grip on Obito’s hips tightened as he slammed forward, hitting his prostate in brutal strokes.
"Cum for me."
Obito’s entire body seized up, his eyes rolling back as he came without a single touch. His cock throbbed, spilling hot streaks of cum onto the sheets, his walls clenching around M/n in desperate spasms.
M/n groaned, slamming into him a few more times before burying himself deep, spilling inside.
Obito shuddered violently, his body spent, legs weak and trembling.
But M/n didn’t let him collapse.
Instead, he pulled Obito up against his chest, his lips brushing against Obito’s sweat-damp temple.
"See how good you are for me?" he murmured, his fingers stroking Obito’s throat, feeling the frantic pulse beneath his skin.
Obito whined softly, leaning into the touch, into the praise.
M/n smirked.
"Good boy."
And Obito let himself sink deeper into M/n’s arms—deeper into the devotion he could no longer escape.
══✿══╡°˖✧✿✧˖°╞══✿══
Later that night, Obito knelt before M/n once more. His head resting against M/n’s lap.
The fire flickered between them, casting long shadows. M/n watched him with something unreadable in his gaze.
"What would you do for me, Obito?"
Obito didn’t even pause.
"Anything."
M/n smiled, reaching out to tilt his chin up. Their eyes met—Obito’s unwavering, the three tomoe in his Sharingan burning like embers.
"Then say it."
Obito closed his eyes and whispered:
"I’d let the world burn."
M/n’s smirk deepened. He leaned in, his lips barely brushing against Obito’s ear.
"Good boy."
