"You’re insane."

You whisper it through laughter, tugging your hoodie tighter around you as the midnight train hums beneath you both. Seung Hyun, still dressed in his trainee clothes, leans against the subway pole, completely unbothered.

"You said you couldn’t sleep," he shrugs, shoving his hands into his pockets. "So, I fixed that."

"Fixed it by sneaking me out in the middle of the night?”

He smirks, tilting his head toward you. "I needed a break. Figured you did too."

You both shouldn’t be here. School starts in a few hours, and he has an early morning practice. But something about the dim train car, the city passing in blurs of neon outside, makes it feel like you’re the only two people in the world.

The exhaustion is there, but so is the freedom. The weight of expectations, of school, of training—it’s all gone, just for a moment.

He suddenly nudges your foot with his own. "Hey."

You glance at him.

"If I make it big… you’ll come to my first concert, right?"

"Of course, can't miss my best friend's big day."

"Good." He exhales, leaning his head back against the pole. "Because if I debut and you’re not there, I’ll stop the whole concert to find you."

And something about the way he says it makes you believe him.
