Overview: Headcanons about GOM (Aomine, Akashi, Kise, Kuroko, and Midorima) having a younger sister who is dating one of them!
Note: Sorry I didn't include Murasakibara! I just got really lazy. :(
"I'll give you what you ever desire, break up with my sister." Akashi offered, glaring at his former tanned teammate. "Sei-nii! That's it! We're leaving." You forcefully removed Akashi's grip on your shoulder, having a silent eye battle as you slammed the door on his face. Akashi did not support you relationship, not even a bit.
Aomine is known to be a player, a pervert, and a lazy man. How could Akashi let his sister fall inlove with him? Akashi just wants the best for his sister. After a year of having a hot and cold relationship with your brother, Aomine knocked some sense into him. Needless to say, Akashi was impressed and saw no more reason to object seeing how his friend's true intention.
"I'm glad you're not the same as your brother." Aomine confesses. Although you are very identical to your older brother, you were the exact opposite of him in terms of personality. You were outgoing and emotionally-driven. Aomine did not see you for your wealth, achievements, or anything! He saw you for you, that made you fall for him despite being mean to you during the first meeting.
You were waiting for your brother so the both of you could go home together. When the gym doors ooen, you dashed towards the entrance, bumping into what seemed like a wall to you but it was actually Aomine. When you looked up, you felt chills run up to your spine, the way he glared at you, it was horrifying.
"How long are you going to sit down, brat? Move."
After that, you kept following him and pestering him even if he gave you mean comments that made you cry. Whenever you cry, Aomine panics. He'd scratch his head and say sorry multiple times, cursing, he'll offer a hug. "Stop crying or I'll kiss you." This just made you want to cry harder.
You'll help Aomine in his study and reprimands him for skipping practices. You're the only one who is allowed to correct him and he's the only one who can bully you.
If you ever did get bully, you have bodyguards ready to protect you in command, a scary powerful brother, and a tall tanned boyfriend built like he's ready to fight.
Aomine will never try to make you uncomfortable. He respects you even if he makes sexual comments, he would never push you to do something you don't like to do. That's how much he treasures you.
"(y/n), where's my kiss?" He grinned at you, bending down so you were at the same height. Rolling your eyes, he always asks for kisses before the game which you thought was very cute of him to do. Without hesitation, you kissed his lips. "Go get them, Dai-kun."
Dating Murasakibara's sister is not something anyone would expect from him. You are reckless, bold, and most of all childish! The complete opposite of Akashi! People can't help but question how you managed to soften the merciless captain of Rakuzan.
"Sei-kun!" Everytime you see your significant other, you would pounce on him, hugging his well-built frame. Akashi would glare at those who would stare, telling them to look away just by staring straight to their eyes.
Akashi would always give you sweets but scolds not only you, but your brother too when you both had too much. "(y/n), I love you but no. I already booked you an appointment." Akashi is persistent to have you attend a dentist appointment atleast once a month to ensure you don't develop any cavities.
When it comes to your brother, he does not really care who you date as long as they treat you well and you're happy but he is really relieved you're dating Akashi. That does not mean he won't crush him when he makes you cry.
People ridicule your relationship, especially the higher class who wants Akashi for their own benefits. Sometimes they go to the extent of hiring people to hurt you, ending up with a failure. There are several perks of having a tall brother who is excellent in basketball, one is he can easily scare of whoever is bothering you, second, you know how to defend yourself when needed.
Whenever those stuck-up bitches shows up, you can't help but show your devilish side. "Eh, I don't care. Get out of my way, bitch." Youmd play with your lollipop, staring down at the crying girl, yelling she'd sue you after you humiliated her.
Akashi will feel proud whenever you stood up for yourself, placing a soft kiss on your forehead and you'd immediately linked your arms around his neck. "Sei-kun, I'm starving~"
He'll always eat you with you, this is somehow like your love language towards one another. You sometimes even go to his school just to eat your bento that you prepared for him. His team is jealous on how a sweet and cute girl ended up dating Akashi.
They are always surprised to see Akashi showing subtle affections. Teasing him about you is a death sentence despite the fluttery feeling in his stomach. Flirting with you? That's a different story.
"(y/n), what am I going to do with you?" Akashi sighed, a smile forming on his lips. You were sleeping on the bleachers and it made him want to carry you home and skip practice but he knows you'll get mad at him if he did. He grabbed his jacketand covered your defense-less state, planting a chaste kiss on your lips. Little did he know, you were actually awake. "Ooh, I didn't know Sei-kun's a pervert!" He would ruffle your hair. "You dare to misbehave, huh? I might have to teach you a lesson, love."
Kise is not really fond of Aomine. Sure they are friends friends but he still had grudges against him. So seeing you, beating the shit out of Aomine, that was something extraordinary. The way the sun highlighted your tanned skin and dark blue hair, Kise fell for you at first sight.
"(y/n)-cchi! I bought you some cake!" Kise always bothered you, he was clingy and chatty. You were annoyed at him at first, who wouldn't? Kise followed you everywhere like some kind of lost puppy! He cried easily was too noisy, yet when a week went by and he was no where to be found, you felt sad. You somehow missed his presence, that's when you realised, you too were inlove with him.
"(y/n)-cchi? What are you doing here..?" Kise did not expect to see you. It was raining heavily and you were drenched from head to toe. Kaijou just lost to Seirin, Kise was feeling down for his first loss. All his own issues faded when you grabbed him by his collar, pressing your lips against his.
Kise's eyes widened, you pulled away, placing your hands on both sides of his face. "Who told you to leave me alone? Huh?! Can't you see I like you too?" He blinked, several times, unable to register what just happened.
Kise became 1000x more clingy after that.
His fangirls are difficult to handle. They always picked a fight on you, saying how you do not meet the Kise's standards. You don't give a fuck of whatever they say about you, you actually enjoy how they cowered in fear and bite back their words whenever you'd look at them with a smirk.
One thing that pissed you off though is when they made nasty comments about your boyfriend. You stopped in your tracks, fist clenched, you turned back, launching your fist towards the girl. She screamed and closed her eyes, waiting for the impact, you stopped your fist an inch away from her face. She fell on the floor, her friends made a run for it.
"Aplogise, bitch." She apologised immediately before scampering away, you'd sigh. "Such a pain in the ass.."
Kise knows about your "little fights" since Kasamatsu actually witnessed the whole thing. He feels honored and proud that his girlfriend stood up for him, your cuts and bruises on the other hand angered him. Kise always made sure to keep you out of trouble after that.
Kise is the only one who can calm you down, only one who can make you smile and act stupid. Your his partner in crime, his princess and his knight, he is very grateful to have you.
Despite how strong you can be, Kise can also fight for you if needed. You need him more than he needs you, without him, everything is off balance.
Aomine bullies him more now that he's your boyfriend.
"(y/n)-cchi! Aomine-cchi is being mean to me!"
"DAMN IT DAIKI! LEAVE HIM ALONE!"
When the two of you are together, that's the only time you are vulnerable. In his arm you feel safe, he felt like home.
The whole Seirin team was stunned to see you, sitting on one of the bleachers absorbed in your phone. Kagami's eyes widened, he recognises you! "S-She's (y/n)! A model in the US!" He exclaimed, making the rest more confused on why someone like you is in their gym right now. Even Riko could not dare to get closer, everyone stood frozen once you glanced at them, staring at them one by ine before your face lit up.
You stood up, smiling widely, before waving. "Kuro-tan! I missed you!" Kuroko coughed, excusing himself as he pass through the crow, greeting you with open arms which you gladly run into. "(y/n)-chan, you didn't tell me you were arriving today."
You would explain to the whole team that you're Kuroko's girlfriend and confirm that you are a model from the US. One thing that caught the team off guard is when Riko asked you if you were somehow related to Kise Ryouta.
"Kise..? Ryou-nii? Yes he's my brother."
The team bombarded you with questions, you were now getting slightly overwhelmed by them. You held out to your boyfriend looking at him teary eyed, he immediately know what you're feeling. "Everyone, you're scaring (y/n)-chan."
Once everything died down, you watched their practice, cheering for your cute boyfriend with Nigou. After practice, Kuroko and you would eat at Majii Burger, catching up and deep talks.
That's where you confessed that you won't go back to the US anymore and transfer to his school. You resigned from your position in the entertainment industry and will now focus on being a (career choice) instead.
Kuroko is the type of boyfriend who is kind of like a dog, he is super loyal to you and no matter what you do as long as it doesn't hurt anyone around you or you, he supports. He may be seen as emotionless but to you, he show all kinds of emotions, love, happiness, jealousy, and he gets super cute when embarrassed.
You always cling on to him, yelling his name with love everytime you see him, crying easily and him comforting you everytime. The team takes a like to you too, you're not really that difficult to get along with.
Riko would ask for help in their training regimen, Kagami also likes hanging out with the two of you (he'll get angry when you get too pda and overbearing though). Overall, you were like their cute little sister who they protect.
So whenever someone gets close to you, as you are famous with both boys and girls, they'll spring inti action and help you out.
You may not be as strong as others mentally and physically, you won't back down when the people you love are messed upon.
When Hanamiya glared at Kuroko, you glared 1000x harder than him. Especially when they hurt , oh you knew you had to talk to him, you stomped your way to their side of the court. You put your best smile, calling him out. "Hanamiya-san, can I shake your hand. I am a fan."
He would snicker, holding out his hand with a few flirty remarks. When you grabbed his hand though, you crushed it using all your strength and he whimpered in pain. Hanamiya cursed, holding his hand. "Oops, did I squeezed too hard?"
He was ready to fight you but seeing several eyes on him, the whole GOM, and Seirin team watching him, he decided not to push further.
Kuroko would scold you though, flicking your forehead before kissing it.
3 words. Best. Boyfriend. Ever.
One thing you hated was sharing Kuroko with your brother. "Ryou-nii! We're supposed to make out now! Get out!"
A Tsundere and a Phantom, what a perfect couple. Kidding. Midorima never thought about dating, the idea of love is not something he minded but when you spiked the ball directly into his face and breaking his glasses, he fell for you, literally.
"Oh, Midorima-kun, sorry!"
Just like your brother, Kuroko, you don't have a lot of presence. He actually taught you how to master misdirection which is a useful skill in your sport, Volleyball. It just happened that you're enrolled in Shutoku and was practicing your one-man spike while he walked into the court.
After that, you kept talking to him. You did not have a lot of friends except for your teammates and you saw Midorima as like your second brother.
Midorima would never admit that he likes you until Takao began to get close to you.
"(y/n)-san, Ilikeyounandayo."
You'd tease him with Takao, copying the way he acts. You'll learn more about horoscopes and oh asa and would always surprise him infront of his house with his lucky item for the day.
Although Midorima is not affectionate, he'll try his best to make you feel that he loves you in his own little way. He would even learn to play volleyball just to play with you. He's a great setter!
Your go to dates would be study hubs, museums, and stargazing.
Since you're very small compated to him, Midorima likes to hold your hand just so you won't get lost. "Shintaro, we're the only ones here." He'd flinched and stammer upon realising you are the only one walking around the park.
Kuroko knows your dating ever since the first day. Kuroko is always there to listen to your rants about your day so it is not a surprise when he sees Midorima eating with your family, stiff like a rock.
"Midorima-kun? Are you okay?" He asked and all of the eyes are now own Midorima who just wanted to crawl to a hole and never come back.
You would go to all his games, offering him a towel. He'll get startled whenever you show up out of the blue though. Takao always teases the two of you which ends up into Midorima beating him up.
Dating Midorima as Kuroko's sister is plain chill, no drama or anything. Both are honest and mindful.
Getting used to hanging out with 2 phantoms would be something he needs to get used to.
"(y/n)?! WHERE'D YOU GO?"
"Shintaro, I'm right infront of you."
