Left out

Peace

"hey hey, why does everyone look like they are gonna murder someone?" asked atsumu, questioning why his friends and teammates, eyebrows furrowed, or why oikawas fists clinched, even sakusa tightened his hold on atsumus. "relax people, we talked about love shit a few minutes ago what happened" he whined.

"nothing tsumu, just, you know, contemplating a few things" replied Sakusa

"yea, like what, planning how to murder my parents"

"yes, exactly that"

"as much as I want that too" he sighed, "I don't want y'all to be in jail ya know, let's just try another plan"

"Like what?" Questioned Osamu 

"Well, let's call our uncle, the blonde one, and tell him everything, and since he is like an actual adult, he can help us with the police, after giving all the proof of course"

"And what proof do we have" This time it was Iwaizumi asking. 

"Well, the recording Omi took of moms phone call, and also the pictures he took of my past injuries."

"wait wait, that isn't enough you know, moms phone call yea, that would be considered verbal abuse to an extent at least but, the pictures, they might think you did it yourself"

"Now that is where your older smarter brother appears," Atsumu said triumphally

"Sure, smart"

"shut yer trap! Anyway, back when we were fourteen, I set up cameras around my room"

"huh, why?" asked Suna

"well I used to always hear someone come in my room and all when I was younger, so I set up a camera in my room and it recorded everything"

 "That's why you barely have any storage on your laptop, and also explains the number of hard drives you have" stated Osamu

"yep! It was expensive to keep buying them, spent most of my allowance on them"

"wait did you ever find out about who was entering your room?" wondered Riseki

"oh", atsumu laughed after remembering who the intruder was, "it was Samu, he used to sleepwalk"

"wait what?! And I wasn't told about that?!" Asked Osamu

"yea luckily you grew out of it"

"yea that's good, I don't want to be scared half to death cause of the antics you might cause during your sleepwalking moments" Commented sauna

"Not you too in"
"glad the mood is better now' thought kita

"Well, after I get out, which is in a day right?" asked atsumu, while looking at his 'omi-omi'

"After two days atsu"

"ugh", whined atsumu, "Fine then, after 2 days let's plan everything with Uncle, we can go home and I can download all the clips, for now, let's enjoy the peace"

"Sure, peace" murmured Osamu

"hey idiot" exclaimed atsumu, "It is peace, for the next two days, relax, don't think about anything relating to this matter, nothing about the past nor the future ok, I forgive you, not fully yes, but I do, and I know you are willing to change, so please, for me, let's have fun for the next two days"

Osamu nodded after all he couldn't form words in his head, he doesn't deserve to hear his brother's voice, reassuring words, after everything he had done to him, all the ignorant words he had said to them, god he didn't want to think about them, and he wants, at his brother's request.

"you know", Atsumu said while looking at Oikawa, "I still didn't get my ice cream dumbass"

"Oh shush! After the way you said it last time you don't deserve it" Oikawa folded his arms and looked to the other side. "wow, kawa wow, I thought you were my best friend"

Oikawa signed, and reached for the bag of ice cream which is half melted by now, however, still enjoyable, and handed it to atsumu, "Here, take you, big baby"

"thank you," atsumu said as he took the ice cream.

For the next two days, they truly were at peace, all due to atsumus request, they had fun joking around, reminiscing fun memories, and suna showing everyone all the stupid clips he took of the twins, all like a big family, the family they are, and the family they deserve to be, even though atsumu still feels as if his team members are just osamus friends, he slowly realizes they aren't just 'his twin brothers friends' and soon he will accept it fully.

After all, family isn't just by blood, but families are made too, yes sometimes it is hard to accept the fact that you can be loved, that you are loved, since some people show it differently. For atsumu, he realized that through the adventures and experiences he went through, mainly with his two best friends and lover. 

Oikawa loves to tease his friends, and give them gifts on random occasions just cause 'it reminded me of you'. He would tease all his close friends, calling them 'idiots' 'dumbasses' and 'I thought you could do better', anyone who doesn't truly know Oikawa, would take offense to that, but his close friends know that's how he shows love, and that's how he gives motivation to his teammates. Take it from Matsun and Makki, they for sure heard it a lot in their lives.

Iwaizumi is a bit similar to Oikawa, which can show why Oikawa is the way he is, got rubbed off by iwaizumis methods of showing love, though when worried he would do anything in his power to show that he cares. For instance, the time Oikawa sprained his ankle terribly, and had to stay home for days, iwaizumi made sure that he is eating, texted him every second of the day, and couldn't care less if he got caught by the teacher, just to show Oikawa that he cares, and he would visit him every day after school. Now if you told anyone that this is how Iwaizumi Hajime acts, they wouldn't believe it, after all, he only shows this side to sakusa and atsumu. Matsun and Makki are not an exception after how they teased him for a whole week.

Sakusa, oh sakusa, how cold and mean he used to be, glaring at everyone due to how much he hates social interaction, and when he first met atsumu in the training camp, oh how much he hated him, after all, atsumu is loud, energetic, cocky, opposite of sakusa in all factors, but after seeing the setters other sides, his other emotions, he fell in love. One moment in fact that truly made sakusa fall in love with atsumu is one morning when he couldn't sleep and decided to practice incredibly early, at 5 in the morning, and got lucky to see atsumu outside by the lake feeding the ducks, what seemed like leftover bread from dinner the night before. How the sunlight hit his face perfectly, his smile brightening up the whole world, and the ducks surrounding him seeking food. Its an obvious lie if sakusa admitted that he didn't take out his phone to capture that beautiful moment. 

He makes sure to show atsumu he loves him in every way he can, by telling him, spending every second he has with him, buying him random gifts, mostly bee and fox related, every single thing, he would make sure to do just so atsumu knows that he is loved. And atsumu? He does the same exact thing, due to sakusa having a fear of being abandoned due to his Germophobia, atsumu makes sure that he knows, that he will never leave his, according to Atsumu, 'soft, sweet, lovable, handsome' omi-omi

Those four together make the perfect friend group, always ensuring each one is happy. If you checked their group chat, that atsumu and Oikawa perfectly named 'Family<3' then you will see how much they love each other. Those 4 create the perfect family.

After all, 

"There are friends, there are families, then there are friends that become family."
