Haikyuu head cannons/oneshots

Head cannons (TsukiYama)

I love this ship and will do Tsukikage next!! (:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Cuddles:

Yamaguchi despite being shy and quiet he it almost always big spoon.

Yamaguchi will lean against the wall or head bored of the bed while Tsukushima lays in between his legs on his chest they think it's the cutest thing ever when Tsukishima falls asleep like that.

When Tsukishima has a nightmare he will walk over to Yamaguchis or he will call Yamaguchi to come over so he can have a hug because he always needs one after a nightmare though they're normally together (they practically live together)

Because they cuddled as friends they have like no boundaries what so ever with each other

Yamaguchi will sit in Tsukishimas lap and just give him hickeys not in a sexual way, just in a something to do way, And when the team found out they thought it was weird at first but just chose to ignore it after a while
(Hinata will poke Tsukishimas hickeys with the back of a pencil so Tsukishima will freak out and try to cover the hickeys better)

Tsukishima prefers little spoon because it helps with his nightmares

If Tsukishima has bad thoughts like he thought about his nightmares he will push his face into Yamaguchis chest they responded by holding Him tighter

Coming out:

Yamaguchi came out first when he was in his first year of middle school he told Tsukishima about how they were non binary He/they (the flag:💛🤍💜🖤) and BI (the flag:🩷💜🩵)

When Yamaguchi came out to Tsukishima, Tsukishima straight up at first told him to fuck off for like a week, because he thought that Yamaguchi would start being perverted towards him but then realized I'm health class that they were always BI

Tsukishima apologized and gave Yamaguchi his favorite squishy fries and a soda as an apology they made up right then and there.

Tsukishima found out he was actually gay when he realized that he actually thought girls were ugly, and that it wasn't just a faze (This was world shattering for him like whole ass panic attack)

He realized while Yamaguchi was sleeping next to him and he started to like freak the fuck out and when Yamaguchi woke up Tsukishima just yelled at him "YOU MADE ME GAY!"

Yamaguchi quickly realized this was a confession and this all happened their 2nd year of middle school towards the end of it

Tsukishima then came out as gay to his mom and brother who already knew by the time he told them at the end of his 3rd year in middle school he did it while holding Yamaguchis have

Tsukishimas mom just hugged Yamaguchi saying "you'll probably Keis first and last boyfriend, you're now my son I'm law!" She was just happy, I helped she already saw yamaguchi as a son (tsukishima wanted to die of embarrassment)

When they told the team they were all unfazed mostly because of how Yamaguchi was the only person not constantly attacked by Tsukishimas insults.

Body love (appreciating each others quirks and different things that one of them had):

Tsukishima would trase Yamaguchis freckles with a glow in the dark mark when ever Yamaguchi wanted to cover up his freckles and he would say things like

"Your freckles are my worlds stars"

"I can see my star sign in your freckles"

And

"If I could I would look at your freckles all day, they mark how many life times we'll be together"

Tsukishima would always kiss Yamaguchis freckles and just kiss all over his face where the freckles were.

When Yamaguchi is wearing shorter shorts (whenever it's warm enough and he's with Tsukishima in private) Tsukishima will draw stars and other things on Yamaguchis thighs where he has some freckles mostly on his inner thighs

Yamaguchi has kind of chubby thighs especially compared to his slimmer figure so Tsukishima likes to squeeze them and lay on them (he literally has a picture of Yamaguchis thighs as their pfp in his phone 🫢)

Yamaguchi always compliments Tsukishimas glasses so he doesn't try to go without them or use contacts (Tsukishima can't use contacts they make his eyes red and itchy which further blinds him 🫤)

Yamaguchi loves Tsukishimas lack of abs like he's skinny but with no abs and Yamaguchi loves to leave hickeys on the middle blockers chest in Yamaguchis words:

"People need to stop saying men look best with abs, they look much better without them!"

He would say it with a pout when Tsukishima wouldn't have taken his shirt off in a long time (over 2 weeks)

Even though Yamaguchi loves looking at Tsukishima shirtless he will respect his boundaries and won't EVER make him take his shirt off if not comfortable though Tsukishima could be being asked to wear cat ears and he wouldn't care because it's Yamaguchi

After high school Yamaguchi stopped playing volleyball and actually got to a healthy weight for him so he was a little chubby and when I tell you Tsukishima LOVED WHEN I SAY LOVED I MEAN LOVED it when Yamaguchi would wear skirts because it make their ass look great and because Tsukishima just loved the fuller look and Yamaguchi, especially knowing he was extra healthy that way.
