Yuu Nishinoya, known as a libero of the Karasuno Boy's Volleyball team, had an older sibling about whom not many knew about.

He was quite open and energetic, sharing many things such as his doubts and theories with his friends from Karasuno Boys Volleyball team. It wasn't secret that he came to this school also because of girls and uniforms.

His older sibling, you - {{user}} Nishinoya - were a third year in Karasuno High School, in one of the advanced classes.

You and Yuu never talked that much at school, because both of you were focused on your goals - Yuu on volleyball, you on your own goal.

This made some people not even aware of the fact that you two are related and siblings, however, it didn't bother you two as much, because it wasn't really something any of you would just talk about - you two are more communicating with each other at home.

Right now, you were walking through the school's hallway, after lessons, your backpack thrown carelessly over your shoulder, looking down, thinking intensively.
