Resentment

It typically felt like everyone forgot Kageyama had a twin brother, and he fine with it. They were nothing alike, which also caused Y/N to ask him what the point in even being twins was. Tobio would just remind his brother was bitter they didn't have any special twin powers, and the y/h/c boy never disagreed.

Y/N was pretty good when it came to school; he studied, made good grades, and teachers really liked him. He said it was because he could actually focus without thinking about which play to bring up to the team next practice, and Kageyama always threw a pillow at him for it. When Kageyama was desperate to be tutored and went to Yachi, his brother actually got angry with him.

"We literally live in the same house and I make the same grades as Yachi-chan!" Y/N yelled one night when Kageyama couldn't figure out a problem. His brother had offered to help but declined.

"I never asked for you help!" Kageyama screamed, and soon enough it was just a screaming match.

There came a time where it had been decided one would be good at school and the other wouldn't. It was accepted to think that, even if Kageyama refused it by saying he was good at school too. No one ever said anything about it to him on how he was wrong even if Y/N always made over 80's and Kageyama had never gotten anything close to that.

Y/N had a lot of friends. He could just smile at someone for them to talk to him and they were already calling him Y/N-san, never using his surname. Kageyama was sure it was because he was ashamed of being related to him, but he had to admit it was easier to know who was. They were fraternal twins, so it wasn't like it was hard to tell them apart but when speaking about them or speaking to both of them at once, it helped.

Y/N always went on about the fact that if Tobio just spent time trying to talk to people and how to smile, then he could be so popular. He didn't have to wear things that Y/N did, because 'it wouldn't fit your aesthetic' but he could just dress to impress more. Kageyama constantly told him to stop teasing him, even if Y/N kept telling him he wasn't trying to.

His brother could get anything he wanted if he just barely tried. He was extremely pretty and used it to his advantage. He could smile, unlike Kageyama, and it was his biggest weapon. Y/N wore sweaters nearly every day, sometimes a pastel orange hoodie, and all the girls constantly talked about him.

"Did you see Y/N-chan today? He looks so cute today," a girl said in Kageyama's class during lunch, and he rolled his eyes. If only she knew that he dressed cute just to manipulate everyone into thinking he was a good person.

Kageyama walked past the two, going to the vending machine like he did every day. He had to walk by the girls who were speaking about his brother though.

"Oh, I always forget he's related to Kageyama," one of them whispered as he passed. "Y/N-chan is so cute and nice unlike his brother."

It never really bothered Kageyama, the whispers, because it came with being related to someone apparently so cute. It pissed him off when he was compared to his brother by those who didn't know them. If they spent that time talking about the differences in the two, they could instead be talking about the volleyball team and how they were going to win nationals.

When he made it to the vending machine near the gym, Y/N was waiting next to it with a milk in hand to give to his brother. He was smiling at Kageyama, and it pissed the setter off for some reason. Maybe it was the fact he heard those girls comparing the two as he left the class, or maybe it was the fact Y/N knew where he always got his milk from. He was just pissed.

"What are you doing here?" Kageyama barked at his brother, and Y/N didn't look fazed by the angry outburst. It was the way the black haired boy spoke, why would it faze him?
