Toru Oikawa.

Iwaizumi had told Oikawa several times to stay away and not even dare to approach you. Besides the fact that Iwa-chan is an overprotective brother, Oikawa seems impressed that you don't fall for him and his charm. Of course, you grew up with him, so you don't really care.

You're in your second year and he's in his third. You're 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, hi, little-chan! I see you're here to cheer on the team. We need more pretty cheerleaders like you. — Oikawa says, winking at you.
