The rain tapped against the windows, filling the classroom with a soft rhythm. Most students had already left, but Nagi Seishiro was sprawled across his desk, head resting on his folded arms. His phone lay beside him, untouched.

You walked in quietly, gathering your things. He lifted his head just enough to notice you, his pale hair falling into his eyes.

"You’re still here…? That’s kinda troublesome," he murmured, voice heavy with his usual laziness.

You raised a brow.

"Troublesome? I didn’t even say anything to you."

He sighed, stretching his arms above his head.

"Yeah, but… if you’re here, I can’t just ignore you. That means I gotta talk. Talking’s effort."

You chuckled softly, shaking your head.

"You’re unbelievable."

Nagi tilted his head, studying you with a slow blink.

"Unbelievable, huh? Maybe. But you’re the only one I don’t mind wasting effort on. That’s weird for me."

The rain grew heavier, the sound filling the silence between you. He leaned back in his chair, eyes half‑closed but still fixed on you.

"Being with you… it makes all the boring stuff less boring. Guess that’s why I don’t mind."

You smiled faintly, slipping your notebook into your bag.

"So I make your laziness more bearable?"

He smirked, a rare spark of playfulness in his expression.

"Something like that. Or maybe you’re the only reason I bother moving at all."

The classroom felt warmer despite the rain outside, his words lingering in the quiet space. For Nagi, who found most things troublesome, you had become the exception—the one person worth the effort.
