HAIKYUU!! HEADCANNONS!

Tooru Oikawa.

Ah, yes... Oikawa headcannons... So many yet little...

I - Iwaizumi is shorter than Oikawa, nonetheless, Oikawa will randomly pick him up by his armpits, and it's to the point he doesn't care anymore.
II - Sometimes the team has to make sure that Oikawa doesn't get disrupted by fangirls during practice, or trying to get to practice and they're often found struggling to leave the crowd.
III - Their S/O is spoiled as fuck.
IV - Oikawa's nonbinary.
V - Ngl, I think they love it when they have practice matches with another team, and another person on that team is like Genderfluid, Non-Binary, etc, so then they can just hang out together and discuss embarrassing shit their team has done, and they just love it when they make plans and purposely misgender each other because it makes their teams go wild angry.
VI - Definitely had a crush on their entire team, first year, second year and third year.
VII - They like to bring Takeru (Their nephew) to practice sometimes and if Takeru gets too buggy Oikawa tackles him and Matsukawa has to break them up because he's the tallest.

(More will definitely be added soon, I just need inspiration go BRRRR)
