2nd person pov

Having two older brothers would seem like a dream right? Especially since there is big age gap of eight years, you would expect them to act all mature and protective of their younger sister. Well that is definitely not the case with Miya Atsumu.

"'Tsumu-niichan, please give it back." You were jumping up as high as you could, but sadly your 183cm older brother was just not giving in.

"Y/n-chan, you are going to have to try a lot harder than that if you want to get your bunny back." He teasingly dangled it right in front of your face. You tried reaching for it but he just moved it higher.

"Nii-chan, please?! You and 'Samu-niichan got that for me." And he just laughs and decided to push your buttons even more. You could feel tears coming out of your eyes.

"It's about time you stopped carrying a doll around everywhere you know?" And the chase and jumping for your doll continued until he smirked and looked outside the window.

"How about we throw your little bunny outside?" And with that you started to get extremely desperate. Even though you were given that doll by him and your other older brother, you still treasured it with all your heart.

"Nii-chan, please don't do that!" And he smirks and opens the window. He then extended his arm and let go of the bunny. You started crying your heart out and Atsumu seemed shocked that you actually cried about that doll.

Luckily, Osamu came in when Atsumu dropped your doll and to say the least, he was annoyed at his twin brother. "You idiot. Stop being so mean to her." He says as he whacks Atsumu on the head.

He then carefully approached you and patted your head. You looked up to Osamu giving you warm smile, which he rarely gives to anyone. With that, you hugged your older brother while crying.

"'S-samu-niichan! I'm sowwy! The doll that you and 'Tsumu-niichan gave me is dirty now!" He just picks you up while still patting your head affectionately as he kicked his brother's shin.

"Geez you seriously act like your the nine year old of the family." And Atsumu looked a bit guilty towards you. He didn't know why you would be crying over a stupid doll.

"Sorry Y/N-chan." He says as he gave you a pet on the head. You move your head from Osamu's shoulder and looked at him carefully.

"I-it's okay nii-chan." And Atsumu smiles at you, but more in a brotherly way, than his usual teasing smirks.

"But why are you so obsessed with that stu-," he was quickly interrupted with Osamu's glare at him. "I mean that doll."

You shyly looked up at both your brother's and just whispered your answer. "Y/N, we can't hear you." Says Osamu, but in a nice tone. You nodded your head and spoke a bit louder.

"Because you guys gave it to me. And it made me feel happy to have something that my two cool brothers gave me. It keeps me company when you guys are gone for volleyball. That's why I carry it around because I don't want to lose it." And with that they both gave you a gentle smile.

Osamu lets you down and tells you to wait there, while he drags Atsumu by his collar outside the room. Of course, this didn't happen without Atsumu's complaints and him fighting back with Osamu.

When they came back, Osamu held your doll. "Sorry, Y/N-chan. Looks like it got a bit dirty." But you didn't hesitate to grab the bunny and hold it in your arms.

You smiled brightly at them, "Thank you 'Tsumu and 'Samu- niichan!" And anyone watching this could have sworn they saw an invisible arrow go through their hearts, as they both kneeled down clutching their chests.

"S-she's too adorable." Says Atsumu while holding on to the shelf.

"Agreed." Says Osamu while using the wall as support.

Bonus extra:

Usually after school your mum would pick you up, but because she was busy, she told you to go to your brother's school and wait with them. You silently made your way to the gym while holding on to your bunny. It felt intimidating with all the loud noises coming from inside.

You opened the door and for some reason most people stopped what they were doing when they saw a small child in front of the door. You got extremely shy and started to regret your decisions. But when you saw your brothers you quickly ran to them and hid behind their legs.

"Y/N, what are you doing here?" He says as he lifts you up. Members of the volleyball team were quite shocked to see Osamu act so friendly with a child.

"Mum couldn't pick me up today so she said to go to your school and wait with for you guys." Then a boy, who seems older than your brothers came up to them.

"Atsumu, Osamu, is this your little sister?" And the both nodded at whoever he was. He looked at you kindly and put out his hand.

"Hi, my name is Kita. What is yours?" You shyly shook his hand.

"M-my name is Y/N." He seemed really kind and cool.

"Well, Y/N do you mind waiting near the bleachers? We just have to borrow your brothers for a bit." And you nodded and Atsumu leads you to the bleachers and sits you down comfortably.

"Y/N-chan, if you need anything just call our names okay?"

"Thank you 'Tsumu-niichan." You day as you hug your bunny tighter. You were mesmerised by how cool volleyball was as a sport. And seeing your brothers act so cool.

When you guys were walking back home after their practice you were practically bouncing up and down.
You were holding onto both Osamu's and Atsumu's hands while one of them held your bunny.

"Why are you so excited?" Atsumu asks you. And you looked up at him with excitement.

"I want to play volleyball!! And be as cool as you guys." They both were taken back and had little blushes on their faces.

Atsumu starts getting excited as well. "Don't worry Y/N! I'll make you the best female setter ever!" But then Osamu interrupts him.

"What do you mean? I'll make her the best female opposite." And the both glared as they continued to argue with each other on the whole way back.

You love your idiot brothers.
