Work Text:
Itachi was perfect.
Everyone agreed on that.
He was brilliant without arrogance, disciplined without cruelty, kind without weakness. He carried responsibility like it belonged to him, like he had been born already knowing how to bear weight without letting it show.
There was only one place where that perfection fractured.
Sasuke.
⸻
Sasuke loved Itachi too much and too badly and too young.
He did not have language for it. No shape to put it in that made sense. He only knew that when Itachi was near, everything inside him burned brighter, sharper, louder. When Itachi praised him, the world felt survivable. When Itachi ignored him, even briefly, something inside Sasuke clawed at his ribs.
It was not admiration.
It was not rivalry.
It was hunger.
⸻
Itachi tried to be careful.
He praised Sasuke, but not too much. Protected him, but did not smother. He treated him like a younger brother should be treated, gently guiding, quietly correcting, always steady.
That was the problem.
Steadiness gave Sasuke something to push against.
The more controlled Itachi became, the more uncontained Sasuke felt.
⸻
Sasuke began to rebel.
Not loudly at first.
He skipped training sessions Itachi recommended. Spoke back when Itachi corrected him. Picked fights he could not win and came home bloodied, daring Itachi to react.
Itachi always did the same thing.
He knelt. He cleaned the wounds. He spoke calmly.
“You don’t need to hurt yourself to be seen,” he said.
Sasuke hated him for that.
⸻
The love inside Sasuke had nowhere to go.
So it turned outward as anger.
If Itachi would not acknowledge it, Sasuke would force him to feel something anyway.
Raised voices replaced silence. Sharp words replaced longing. Sasuke learned exactly how to provoke reactions from someone who rarely showed them.
He criticized Itachi’s choices. Mocked his loyalty. Accused him of caring more about the village than his own blood.
Every word was a test.
Every argument was a plea disguised as violence.
⸻
Itachi endured.
He always endured.
That was his flaw.
⸻
The first time Sasuke hurt him deliberately, it was during training.
A spar meant to teach control.
Sasuke ignored the signal to stop.
He struck harder than necessary, faster than expected, driving Itachi back with a ferocity that made onlookers freeze.
Itachi blocked the final blow, but not completely.
The impact knocked him to the ground.
Silence fell.
Sasuke stood there, breathing hard, eyes wide with something like triumph and terror mixed together.
Itachi got up.
He did not raise his voice.
“That was too far,” he said.
Sasuke wanted him to be angry.
He wanted him to shout.
He wanted him to break.
⸻
So he escalated.
Words turned cruel. Accusations turned personal. Sasuke learned exactly where Itachi was soft and pressed there relentlessly.
You’re a coward.
You hide behind duty.
You don’t love anything enough to choose it.
Each sentence was a blade aimed at the one person Sasuke loved more than himself.
Itachi listened.
And that made it worse.
⸻
The breaking point came quietly.
No audience. No sparring ring. Just a hallway and a moment where Sasuke’s restraint finally failed completely.
He shoved Itachi.
Hard.
Itachi stumbled and hit the wall, breath knocked from his lungs. For a second, he looked stunned, not hurt, just… shocked.
Sasuke froze.
The world snapped back into focus.
⸻
“I didn’t mean to,” Sasuke said immediately, voice cracking. “I didn’t mean—”
Itachi straightened slowly.
For the first time, his expression was not calm.
It was wounded.
Not physically.
Emotionally.
“Sasuke,” he said softly, and something in his voice finally fractured, “this is not love.”
The word hit like a blade.
⸻
Sasuke collapsed inward.
Everything he had been doing suddenly looked exactly like what it was.
Cruelty.
Control.
Violence disguised as need.
He saw Itachi not as an untouchable constant, but as a person who could be hurt. Who had been hurt. By him.
“I don’t know how to stop,” Sasuke whispered, hands shaking. “I didn’t want to hurt you. I just— I don’t know where to put this.”
Itachi did not reach for him.
That hurt more than any blow.
⸻
“I should have seen it sooner,” Itachi said quietly. “I should have stopped it sooner.”
Sasuke shook his head violently.
“No. Don’t. Don’t make this yours.”
Tears burned, humiliating and uncontrollable.
“I ruined it. I ruined you. I ruined everything.”
⸻
That night changed them.
Not with screaming or punishment or exile.
With distance.
Itachi set boundaries for the first time. Clear. Unyielding. Necessary.
Sasuke accepted them because he had no choice.
Because loving someone did not give him the right to destroy them.
⸻
Regret stayed.
Not dramatic. Not redemptive.
Just constant.
Sasuke carried it every day, learning slowly what love was not.
Not possession.
Not obsession.
Not pain inflicted to be felt.
And Itachi, still perfect in almost every way, carried his one flaw with him too.
That he had loved Sasuke gently when what Sasuke needed was help.
And neither of them ever forgot the moment when love, uncontained and unexamined, crossed a line it could never uncross again.
