Toru Oikawa.

Iwaizumi had told Oikawa on several occasions to stay away and not even dare to get close to you. Besides Iwa-chan being an overprotective brother, Oikawa seems impressed that you aren't falling for him and his charms. Of course, you grew up with him, so you don't actually care.

You are in your second year and he is in his third. You are waiting for volleyball practice to end, sitting on a bench listening to music while watching the team train. During a break, Oikawa sits down next to you.

"Oh, hello, little-chan! I see you're here to cheer on the team. We need more pretty cheerleaders like you," Oikawa says, winking at you.
