iwaizumi eldest child with tiny younger siblings oikawa youngest child with siblings way older than him

I SAID WHAT I SAID

oikawa inadvertently giving iwa TIPS! “i always loved it when my nii-chan cut apples like little bunnies!” ... you bet your ASS iwaizumi’s in the kitchen at 5:30 making TINY APPLESLICE BUNNIES

oikawa being good with kids too because of takeru...... helping iwa....... the youngest girl is always looking for oikawa when they go out because she thinks oikawa is her brother too.....

WHEN SHE REALIZES OIKAWA IS IN FACT NOT HER BROTHER SHE THROWS A MAD FIT and the older ones pout at hajime all day until their parents gently explain to them that oikawa can’t be their brother... yet... but since he’s a family friend he already is, in practice!

hajime doesn’t confront his parents LMAOOOOO just lays in his bed staring at the ceiling about the implications until there’s a tiny tiny knock on his bedroom door and the second youngest comes in and climbs into his bed and in a very quiet voice asks how oikawa nii-chan can be

their brother and iwaizumi takes like the deepest breath he’s ever breathed in his life and tells her about in-laws, citing his parents and their siblings as an example. she goes, “i’m way too young though” and hajime laughs and whispers, boys can like boys too and her eyes get

super big and wide and she says “do you like boys too?” and he says yeah, i like boys too and she gets all thinking, tiny brain cogs whirring. and then she scrunches her nose and says, “do you wanna marry oikawa nii-chan though?” and although that had already been implied it’s

not like he’s tackled that question before and so bluntly and then he goes on to explain that, well, you gotta real love someone to marry them because you’ll be spending your life with them you know? and then it becomes a whole ass crash course lecture on choosing your spouse and

at the end of it she just kinda, “so... you don’t?” and he’s just kinda. oh. ohhhh. well. and puts his chin on her tiny head in a hug and pouts invisibly and says, “i guess i do.”

and she just yawns and goes, “okay. good.” and then she tells literally everyone at breakfast.
