Kenji Takesubo sprinted the last stretch of the hill, backpack bouncing against his shoulders, the morning air still cool enough to sting his lungs in a good way. He reached the top just as the first bell rang in the distance—perfect timing, as always. Grinning, he slowed to a jog, wiping sweat from his brow with the sleeve of his navy blazer. Seventeen years old, second-year at Minato High, track team sprinter, and officially the guy who could make anyone laugh during lunch. Life felt fast, bright, and exactly the way he liked it.
He spotted her near the school gate, same as every morning since elementary school. Aiko Nakamura stood under the big cherry tree that was just starting to drop its last pink petals of the season. Her long black hair caught the light, swaying slightly as she scrolled through her phone. She wore the standard uniform—pleated skirt, white blouse, red ribbon—but somehow she made it look softer, like the world had decided to be gentler around her.
"Yo, Aiko! You're gonna make the tree jealous if you keep standing there looking that pretty," Kenji called, sliding to a stop beside her.
She looked up, eyes crinkling into that familiar half-moon smile. "You're late again, idiot. And sweaty. Gross."
"Early is for people who don't enjoy life," he shot back, falling into step beside her as they passed through the gate. "Besides, I beat my personal best on that hill. You should be proud of your childhood friend's athletic greatness."
Aiko rolled her eyes but laughed—the light, easy sound that still made something warm twist in his chest after all these years. "You say that like I asked you to race the sunrise. Come on, we'll be late for homeroom."
They walked the familiar path across the courtyard: past the fountain that never worked properly, past the bulletin board plastered with club recruitment flyers, past the group of first-years who always stared when Kenji waved like some kind of celebrity.
He had worked hard for that—joining track freshman year even though he used to hate running, forcing himself to talk louder and smile wider until it stuck. All of it so he could stand next to her without feeling like the goofy kid who used to eat dirt on a dare.
Back in middle school, Aiko had once said, offhandedly, "I like guys who are reliable and energetic, you know? Someone who can keep up with me." That sentence had lodged in his brain like a splinter. So he changed. Grew taller, got faster, learned how to make jokes that landed instead of falling flat. He became the version of himself he thought she might one day look at twice—not as the boy next door, but as someone worth choosing.
They reached their classroom on the third floor. Kenji dropped into his seat by the window while Aiko slid into hers two rows ahead. He watched the back of her head, the way her hair shifted when she tilted it to listen to the teacher. Routine. Comfortable. Safe.
Lunch came like it always did. Kenji grabbed two bentos from the convenience store on the way back from morning practice—one for him, one for her, because she always forgot to pack enough. They ate on the rooftop, the one spot the teachers pretended not to know about.
"So," Aiko said around a bite of tamagoyaki, "you're running in the prefectural qualifier next month, right? You better not embarrass me."
"Embarrass you?" Kenji clutched his chest dramatically. "I'm gonna win it just to see you cheer like a maniac in the stands. Imagine it—'Go Kenji! My best friend is amazing!'"
She snorted. "I'll cheer, but only if you don't trip over your own ego on the starting line."
He laughed, loud and genuine. This was it. This was enough. Almost.
As they packed up, Aiko's phone buzzed. She glanced at it, and her expression softened in a way Kenji hadn't seen before—small, private, almost shy.
"Who's that?" he asked, keeping his tone light.
She hesitated for half a second. "Just… someone from class 3-A. Rei-kun. He asked if I wanted to study together after school sometime."
Kenji's chopsticks paused mid-air. Rei Hashimoto. The third-year everyone called the school's prince charming—tall, perfect grades, captain of the debate team, face that belonged on posters. The guy girls whispered about in the halls, the one who smiled politely at everyone and somehow made it feel personal.
"Oh," Kenji said. His voice came out normal. Too normal. "Cool. He's… nice, I guess."
"Yeah." Aiko tucked her phone away, cheeks faintly pink. "He is."
They headed back downstairs in silence that wasn't quite uncomfortable yet, but heavier than usual. Kenji kept his grin plastered on, cracking a joke about the cafeteria's mystery meat to fill the quiet. Aiko laughed, but it sounded a little distant.
By the time the final bell rang, Kenji was already planning tomorrow's run—faster this time, harder, until the burn in his legs drowned out everything else.
He didn't know it yet, but the route he had run every morning for years was about to change.
