everyone x oikawa

i want a hogwarts au in which iwaizumi was sorted into gryffindor. refusing to be seperated from his bff, oikawa made a fuss and tried convince the sorting hat into putting him in gryffindor too instead of slytherin but the hat would have none of that. oikawa threw a temper tantrum first but soon figured out ‘hey if that old hat won’t let me then i might as well let myself in’ so within the first week he had managed to charm the fat lady and sneak into the gryffindor’s dormitory and also sit in gryffindor’s table during meal. gryffindor’s firsties welcomed him due to his obvious charm and iwaizumi was ofc happy and all but soon began to worry for his best friend because duh he needs to spend more time with the slytherin house too!! so iwaizumi began to sneak into the slytherin’s dorm and occasionally eat at the slytherin’s table and because he was iwaizumi the slytherin grew to love him too. and this arrangement continued on without much protest from anyone especially when their group of friends from their respective house started to befriend each other too, thus how iwaizumi and oikawa promoted interhouse unity.

Haven’t read the manga but… there has to be a point during the karasuno vs. aoba josai match where Oikawa for a moment, begins to lose faith and doubts himself. They might actually lose.
But Iwa-chan is there to pick up his babe and lift his spirits.
