Iwaizumi was well known for being Oikawas best friend but not more popular than him so due to this he never really spoke about his own crushes or relationships

His eyes were on u most of the time when he was playing against another team seeing if u were paying attention to him whilst tryna show off

Currently Oikawa was trying to woo you as Iwaizumi caught eye of this and instantly shot Oikawa a glare of envy & anger

He absolutely despised his best friend right..Shittykawa…
