Best Friends

You personally stopped playing sports after this one thing that happened when you were a kid. You were playing football with your older brother and at this time, you were 12. He threw the ball to you, low enough for you to catch it without it hitting you in the face. You caught it, putting it under your arm and running towards your brother. He was slightly crouched down, arms bent at his sides and his hands out. From there on, everything else was a blur to you, but clear as day to your brother.

Next thing you knew, you were woken up by beeping in your ear and something warm on your arm. You cracked your eyes slightly, being blinded by the bright light coming from the room and the window that was nearby. Your eyes traveled down to your left arm, seeing someone laying on it, soft snores coming from them. At the time, you couldn't make out the figure next to you, until you heard the door open.

"Hey.. You're awake!" Someone tall with (h/c) short hair and a water bottle and something that looked like a to go coffee cup. That voice made you recognize it was your older brother, which made you wonder who was at your side. You only gave a small nod with a hum and you looked up at the ceiling.

"Heh... Tanaka-kun is still sleeping.." Your brother softly chuckled to himself, setting down the coffee cup on a side table and opened the water, taking a swig. Tanaka-kun..? TANAKA-SAN?!Your eyes widened as you looked over at the boy next to you, his blond hair becoming overly familiar. You and Tanaka might be only 17 days apart, but he always acted like your younger brother even though he was the older one. And ever since elementary, you two were conjoined at the hip. Did everything together, stayed next to each other, comforted each other, everything siblings would do. Like what your brother did for you. And since (b/n) ((Brother's name)) was two years older than Tanaka's sister, you guys were always together. And you fracturing your ankle didn't change any of that.

Back to the present time, it was the first day of your second year. That fracture prevented you from doing any sport or much physical activity. Yeah, your fracture still hasn't fully healed yet, even after four years it hasn't fully healed. So now, you wear an ankle brace that your doctor told you to wear. To "take off some of the pressure" of the fracture, but it only put more on it.

"(y/n)! Wanna come to volleyball practice?!" Tanaka asked excitedly from next to you, a bright shine in his eyes. His personality did at full 180 (crazy.. thinkin 'bout th- okay, sorry, I'll stop) when he was around you. Around school, he was the delinquent kid, always having that weird look on his face. Around you, he was himself, but more... feminine...? Is that the right word? I mean, whenever he wants something he would give you the puppy dog eyes or would have that same shimmer in his eyes. Also, funny story, he took his sisters dress from her graduation and put it on, including the heels, and danced around. All because he lost a bet with Nishinoya.

"Yeah, sure! It'll be nice to see the team again. Damn... Suga, Daichi and Asahi are all third years..." You looked at the floor, thinking about their graduation at the end of the year, your mind thinking of only the negative things. That's what was different between you two. You thought about the worst case scenario and he thought about the up side of everything. And I mean everything.

"Yeah.. they are... But I'll see ya later shorty!" Tanaka snickered and walked into his classroom, being greeted by Noya and the others.

"Only by four inches, moron!" You called into the classroom, Noya laughing at your comeback but waved at you sweetly, as if flirting with you. And his actions earned him a slap on the back of the head from Tanaka, his eyes narrowing at him. Noya knew about Tanaka's massive crush on you, with only fueled the flame of Nishinoya flirting with you to drive his friend to confess. You on the other hand were totally oblivious to Tanaka's obvious hints. Him trying to show you off to his friends during your first year, him asking for you to come to his place to study or just watch movies. Just so many things was obvious, but you refused to find them as hints. You also had a massive crush on him, but were never teased about it since you didn't have many friends. You had one in your class, but she's been out sick for the last two weeks and you've never told her.

"Tanaka! You coward! You have to tell her today or I'm telling Suga not to set for you until you do!" Nishinoya threatened, his finger in Tanaka's face, making the buzz cut boy flinch, not expecting for him to be that close.

"Noya, she's my best friend. Technically my sister! She'll say no.." Tanaka bit his bottom lip, grabbing his pencil again and continued to doodle on his paper. 

"Fine. If you don't say it, I will." Noya smirked devilishly, quickly standing up and running out of the classroom. Tanaka's eyes widened at his words and immediately followed him, following close behind.

"Noya! Please don't! I'll do anything! I'll help you practice, I'll buy you food, anything! Please don-!" He begged Noya the whole way to your class, his words coming to a stop and Noya entered your classroom, walking over to you slyly.

"Oh, hi Noya-san! Why are you in here? Class is-" You were cut off by a breathless Tanaka, walking over to Noya and slapping his hand over his mouth.

"Sorry, (y/n). He's an idiot and doesn't pay attention to the time." Tanaka said through his gritted teeth, clearly angry. Noya elbowed him in the stomach, Tanaka doubling over, holding his stomach.

"Noya!" Your eyebrows came together in confusion, almost anger as you quickly got out of your seat, kneeling next to Tanaka, putting your hand on his back.

"Oh, he'll be fine! I gotta say this quick, but delinquent boy over here likes you~!" Noya waved off what he did to Tanaka before putting his hands together, holding them close to his chest. A bright red blush crossed your cheeks and heat rose up to Tanaka's ears, spreading to his cheeks.

"Wait... what..? You do?" You asked quietly, tilting your head at Tanaka. He only looked away, before standing up, one hand on his stomach as he started to walk away. Noya's shoulders fell, finally realizing this might not have been the best idea.

"Tanaka," No response. "Tanaka!" Your voice rose slightly, making the male pause for a split second.

"God damn.. I like you too, Ryuu!" That's what made him stop fully, his body stiffening. "Ever since that time in the hospital... You stayed for three days.. Made sure I was okay and had everything I needed when my brother went to work. I knew we were only twelve, but yeah... four years.. of bundling these feelings." Your hands clenched at your sides. You felt like crying, knowing that he didn't even turn around the whole time you were talking. What if this was just some prank? Some lie? What if I'm dreaming..? Fever dream..? That's what almost broke you until there was a pair of arms and someone's buried into the crook of your neck.

From there on out, you and Tanaka dated each other throughout high school and possibly though college and all that good stuff. What can you say, dating your best friend is a great thing.
