You are Iwaizumi's younger brother. And he texted you earlier to bring him his lunch during practice.

You walk into a gym while a team is practicing, and you look around a notice someone standing on the side. So you decide to walk up to him.

"Hey, by any chance, is Iwaizumi here." You ask as you look up at him, and you notice how tall he is.

"No... he just left. But who are you? I'm Oikawa, by the way." He says as he flashes a smile and looks you up and down.
