Iwaizumi had told Oikawa in multiple occasions to back off and not even dare go near you. Other than the fact that iwa-chan is an over protective brother. Oikawa seems impressed how you're not swooning for him and his good looks. Then again you've grown up with him so you really don't care.

You're a second year while hes a third year. You're waiting for volleyball practice to be over sitting on a bench listening to music as you watch the team practice. During a break Oikawa sits next to you.

"Awww hey shortie-chan! I see you're here to encourage the team. We need more cute cheerleaders like you." Oikawa says winking at you.
