no one comments on it but everyone notices how iwaizumi pays extra attention to kageyama (because he practically saw the boy grow up) and hinata (because he saw him collapse in the kamomedai match and he wasnt going to let that happen again on his watch)

bonus: iwaizumi is one of the few people that ushijima happily converses with and the rest of them are just. Confused. because who exactly is this man

bonus (2): he picks on atsumu sometimes like the rest of the team because the other setter reminds him of oikawa sometimes but no one will ever hear him say that out loud

bonus (3): iwaizumi trades oikawa stories with hinata and they laugh about oikawa falling face-first onto the sand together and the blackmail material alone is enough to make hinata his favorite

bonus (4): iwaizumi is very fond of sakusa because in his humble opinion sakusa is the player who is the most concerned about his own well-being. surprisingly enough, sakusa warms up to him Very Quickly.

bonus (5): iwaizumi bonds with hoshiumi regarding tall people who undermine their worth ("my best friend is only 5 centimeters taller than me but he makes me feel like a midget." "ah, iwaizumi-kun, that 2-meter pole over there? he used to do the same to me!")
