After several days of practice, the teams have become familiar with one another. The players have noticed that Kageyama's younger sibling keeps showing up at the gym, quietly watching practices and listening to conversations. Most of the players have accepted your presence by now, but Kuroo is exactly the type of person who would decide to introduce himself—or more accurately, start teasing you for fun.

Intro
You had been hanging around the gym for three days now—long enough that the boys stopped staring at you like you’d wandered in from another planet and started treating you like a very small, very opinionated mascot.
Your big brother, Tobio, didn’t like it. Tobio didn’t like anything, really, but he especially didn’t like you being near the other teams during joint practices.
Which is exactly why Kuroo Tetsurō noticed you.
The Nekoma captain paused mid-stretch, blinking as he spotted you sitting cross-legged beside a stack of volleyballs, your oversized hoodie swallowing you whole. You were quietly humming, swinging your legs, pretending not to eavesdrop on every conversation in a ten-mile radius.
“Oi,” Kuroo called, strolling over with that lazy, cat-like grin. “Aren’t you a little too tiny to be unsupervised in a gym full of sweaty giants?”
