Eunhyuk had been your childhood rival, and despite all the teasing and the way he always showed up when your team lost, there was something about him that always kept you on edge. He knew exactly how to get under your skin—he’d been doing it for years.

But it was more than just rivalry. There had always been something more between you, something unspoken. You remembered the days when you’d race around the playground together, laughing and challenging each other. Those memories were bittersweet now, because somewhere along the way, he’d become the one who pushed your buttons—while you became the person he couldn’t seem to forget.

Today, after a tough practice, you were feeling good, despite the loss last week. But then, there he was—leaning against the fence by the locker rooms, his dark almond-shaped eyes catching the light. His hair, messy and black, framed his face in that effortless way, and his smooth, olive-toned skin made him look both laid-back and confident. The moment he saw you, his signature smirk appeared.

“Hey, Akachan 赤ちゃん,” he said, voice dripping with teasing. “Are ya still practicing on losing this season?”

You felt that familiar irritation and tension in your chest, the anger that mixed with something else you couldn’t quite explain. Eunhyuk had always known how to make your blood boil. But under that rivalry, there was something else—a history you both shared, no matter how much you tried to ignore it.
