Chapter Text
The roar of the crowd reduced to a distant echo in his ears, as he walked to the locker room. Blue Lock had won 4-3 and Yoichi Isagi had scored the final, decisive goal, the one that sealed it all. A volley born from instinct, from Rin's unexpected pass, from that single, razor-sharp moment where everything clicked.
But victory tasted strangely hollow now.
Isagi had found Rin in the locker room right after the final whistle, the chaos of teammates shouting, slapping backs, blurred into background noise. Rin was sitting in front of his locker with that same cold, unreadable expression he always wore like the world was something to be dissected rather than felt. His teal eyes locked onto Isagi's, sharper than any blade.
"You're my rival now," Rin had said. Flat. Final. No warmth, no congratulations, no hint of the partnership they'd just forged on the pitch."I’ll surpass and destroy you and Sae to become the best striker.” Just those words, delivered like a verdict. Then he turned and walked away, leaving Isagi standing there amid the celebration, chest tight with something he couldn't name.
Rival.
The word echoed in Isagi's head as he trudged toward the hotel Ego had arranged for the team. The night air in Tokyo was cool, carrying the faint metallic scent of recent rain on concrete. Streetlights cast long, lonely shadows across the sidewalk. His legs felt heavy, not from the match, though every muscle screamed, but from something heavier settling inside his heart.
He really hates me?
The thought came unbidden, small and pathetic, and Isagi hated himself for it instantly. Why should it matter? Rin hated everyone, didn't he? That was just who he was: cold, obsessive, driven by a fire that burned everything around him to ash if it got in the way of surpassing his brother. Isagi had always known that. They'd clashed before violently, ego against ego. He'd told himself each time that it was just rivalry. Pure, clean, soccer-fueled rivalry.
But tonight the word rival felt like rejection.
He quickened his pace, hands fidgeting with his soccer bag then shoved deep into the pockets of his team jacket, shoulders hunched against the chill that wasn't really there. The hotel wasn't far now Ego had booked something sleek and modern, all glass and sharp angles, the kind of place that made you feel small just by existing in it. Isagi kept his head down, replaying the moment over and over.
Rin's voice. Low. Emotionless. “You're my rival now.”
Not ‘good game.’ Not ‘you surprised me.’ Not even a grudging nod of respect.
Just… rival.
And somehow that single label hurt more than any insult, any glare, any time Rin had ever dismissed him as irrelevant. Isagi's throat tightened. He blinked hard against the sting building behind his eyes. No. Not here. Not in the middle of the street like some kid who lost his favorite toy.
He focused on the rhythm of his footsteps. One. Two. one. two. The hotel sign glowed ahead. soft gold letters against black glass. Almost there.
The lobby was quiet, almost reverent. A single night clerk glanced up, offered a polite nod. Isagi mumbled something about being with the Blue Lock group and received a keycard in return. Elevator. Soft ding. Empty hallway carpeted in muted gray. He walked to his door and swiped the card. Beep. The door unlocked. He walked inside.
The room was dark and cold. He didn't bother with the light.
The door clicked shut behind him, and that was it the final barrier between him and whatever had been clawing at his chest since Rin's words.
Isagi leaned back against the door, slid down until he hit the floor, knees brought up to his chest. And then something snapped.
Tears came hot and fast, silent at first, then shuddering sobs that wracked his whole body. He pressed the heels of his hands into his eyes as if he could force them back in, but it was useless. The dam had cracked, and everything poured out.
“Why does it hurt this much?”
He gasped for air between sobs, forehead dropping to his knees.
“It's just Rin. Just Itoshi Rin. The guy who's always looked at me like I'm an annoyance, like I'm in his way, like I'm nothing but another stepping stone.”
But that wasn't true anymore, was it? Somewhere along the line, through every glare, every challenge, every time Rin had pushed him to the absolute limit on the field. Something had shifted. Isagi had started noticing things he shouldn't have. The way Rin's hair fell across his forehead when he was concentrating. The rare, fleeting smirk when he pulled off something impossible. The intensity in those teal eyes, not just anger, but hunger, focus, a kind of brutal beauty that made Isagi's pulse stutter.
He'd told himself it was admiration. Respect. The natural byproduct of two egos clashing until they sharpened each other.
But admiration didn't make your chest ache like this.
Respect didn't leave you crying on a hotel room floor because someone called you their rival.
Isagi choked on another sob, curling tighter into himself.
He had fallen for him.
Slowly. Stupidly. Inexorably.
For the boy who barely tolerated him. For the one who saw the world in terms of destruction and domination. For Rin Itoshi, who probably didn't even know how to feel anything softer than contempt.
And the worst part? Isagi couldn't even be angry about it. Because even now, even through the tears and the humiliation, part of him still wanted to chase that cold silhouette. Wanted to stand on the same pitch, lock eyes, and prove, again and again, that he belonged there. That he mattered.
That maybe, just maybe, Rin would look at him one day and see something more than a rival.
The sobs eventually slowed to quiet hiccups. Isagi stayed on the floor, back against the door, staring blankly into the dark room. His cheeks were wet, his eyes swollen, his throat raw.
Outside, the city hummed on, indifferent.
Inside, Isagi sat in the wreckage of his own heart, wondering how something as simple as rivalry could hurt more than any defeat ever had.
And knowing deep down, where the truth always hid, that he wasn't ready to let it go.
Not yet.
Maybe not ever.
