What if?

Highschool

Atsumu and his brother Osamu known as the Miya twins are very popular. Atsumu started dating a girl named y/n, She was such a sweet person and she was always the top of the class.

No one really hated her and she was a quiet person. When y/n first met Atsumu, she was studying in the library and she needed to get a book.

That time Atsumu's homeroom teacher was forcing him to study. So he came to the Library and he had to look for this English book, he was going through an aisle of books and he found y/n struggling to get a book on the top shelf. Their library was very large. He giggles and that caught y/n's attention and she looked at him.

"Do you have a problem with my height?" She asked him.

"Haha no not at all, it's just that you could've used the ladder." He said pointing at the ladder beside her.

She looked at the ladder and her face turned pink because she was embarrassed because she was so focused on getting the book, she didn't see the ladder. Atsumu walks up to her and grabs the book.

"Wait this is the book I was supposed to get." He says with his eyes wide open.

"There is none left but if you want we could share it, I heard Mr.Kou yelling at you to study." Y/n said.

"Oh the old geezer...yeah let's share the book and you could teach me 'bout it?" He asked.

"Sure, I don't mind." Y/n said and they stayed till 5:00 PM to study about it.

Atsumu offered y/n to walk home and they were on their way to her house. Y/n unlocked her door and opened it.

"Thank you for walking me home Miya-san." Y/n thanked bowing.

"Geez don't be so formal also call me Atsumu it feels like yer calling my brother, anyway I should be thanking you. So thanks for teaching me." He said.

Y/n giggled, "No worries honestly you're a fast learner and if you keep up with learning then you can surely get your grades back. Also, you have a brother?" Y/n asked.

"Yeah my twin brother, Oh I've been wondering where yer family is?" He asked, tilting his head inside.

"Oh I'm an orphan, I used to live with my Aunt but she couldn't take care of me anymore and this weekend I'm moving to the school's campus." She answered.

"Ah sorry I shouldn't have asked you that but it's good that you're not going to be living alone for long." He said.

"No worries and Yeah I'm pretty excited." y/n said.

That's where their friendship began. Y/n would usually sit alone at lunch because she didn't have a lot of friends. She had friends but her 2 best friends attended a different school. Her 2 best friends were Kiyoko and Yachi. She sat on the rooftop and opened her homemade lunch.

"Huh! Y/n?"Atsumu said in shock. Y/n was startled and looked back.

"Atsumu-kun?" y/n said seeing the tall male.

"Oh, it is you! thank god I could've been killed." He said, sighing and sitting down next to her.

"Oh, are you okay?" Y/n said looking at him.

"Hmm yeah just running away so those girls won't find me." He said pointing at the girls on the field.

"Haha you're popular!"Y/n said laughing.

"Hmph Samu has a good hiding spot and he won't tell me!" Atsumu says pouting.

"Is Osamu-kun you're twin brother?" Y/n asks him.
