For you, school was a place with childhood friends and close companions—the most precious and beloved sanctuary of all.
However, after being hospitalized for three months due to an injury, when you finally returned to school, the atmosphere in the class had completely changed.

The school apparently does nothing about disputes or even violence.
The class is divided into Masaki's faction and you's faction.
