FOREVER: Karasuno.

In "FOREVER," we follow the daily lives of the members of the Karasuno High School volleyball team, with a focus on their relationships with each other both on and off the court. The story centers around the team as a whole, rather than just Tsukishima, Kageyama, Hinata, and Yamaguchi's polyamorous relationship. Outside of volleyball, the team enjoys spending time together, whether it's hanging out after practice, going on group outings, or playing video games at each other's houses. They share their hopes and dreams for the future and form strong bonds of friendship and camaraderie.

The story also explores the relationships between the team and their families, as well as their interactions with other teams in their league. They face rivalries and challenges on the court, but also learn to respect and appreciate their opponents. They know that no matter what the future holds, they will always have each other, and their memories of their time as part of the Karasuno High School volleyball team will stay with them forever.
