There's 3 of them! (Haikyuu fanfiction)

Who?

Kageyama was walking Around doing his weekly errands when he spotted a red headed spiker in the crowd.
"OI Hinata!" The boy turned around to look at the voice
"Hello?" He looked really confused "do I know you?" Kageyama was really taken back when he heard the words coming from the boys mouth
"You dumbass it's me!" He began to scream at him."Kageyama!"
The boy he claimed to be Hinata didn't say anything he just look really confused.
" OI you asshole don't just run off like that!" Kageyama looked at where the yelling was coming from to see...Hinata?
"Sorry some confused idiot was yelling at me..."
"What why? Who would know you"
"Apparently him" he turned around and pointed at Kageyama
At this point Kageyama was as confused at the two boys In front of him
"Eh whatever just don't run off like that Natsu was really freaking out that you ran off!" The boy was yelling at the other while pulling him away from where Kageyama was.

When...
"What if we never find them onnii-chan" a little girls voice was heard

"SHIT we left him with Natsu!" They started to walk backwards to where Kageyama was.
"He is going to kill us!" They had reached Where Kageyama was.

*meanwhile in Kageyama's head*
'So I ran into two hinata look alike'
*calculation noises*

"Come on I heard them right over there!!" The voice was heard again but louder. Then a little girl with the same bright red hair as the other boys.
"I see them right there!" She had a bright smile on her face when she spotted them. She began to pull on arm to get to them eventually she let go of the arm and ran towards them.

"Big brothers!" She jumped at at them one of them quickly caught her.
"Natsu!!" Another boy ran out of the crowd. He ran towards his sister and the boys.
"Where were you!" He began to lecture the boys.
"This random dude was saying he knew me and calling me a dumbass!" He shot back
"Who?"
"Him" he pointed towards Kageyama
Kageyama looked in the direction of the two boys to see another hinata.

"ANOTHER ONE!" He pointed at hinata

"Oh hi Kageyama!" He pushed past them to approach the setter "sorry about them! They may be older but their stupid as hell!" He began apologising to Kageyama.

"Their your siblings right? I'm not going crazy?"
"Yep! And if shota over didn't run off none of this would have happened." He quickly shot a glare at one of his brothers

"Sorry Kageyama! have to finish the grocery shopping see you at training!" He smiled at the setter before running off to join his siblings.

-Kageyama POV-
As he stopped and stood next to his sibling I realised that his brothers where 4 centimetres taller than Hinata.
But I was still had to get the errands done before I could think about what just happened

-3ed person POV-
"we're home mum!" Shiota yells as he gets inside
"Welcome back guys!" She runs to see all of her kids
"Mummy" Natsu yells as she ran and jumped into her mothers arms "shota and shiota Met Shōyō's friend today!"
"Really!"
"Yeah and he thought that they were Shōyō!" She starts to giggle as she tells the story her brothers told her.
