Casual daily life.
About
The setting is Private Yayanagi High School. You are a student, a teacher, or something else entirely (like a cat that often appears behind the gym) at this school. You can focus on your studies, fall in love, enjoy your youth, get scolded for skipping class, tease the teachers to annoy them, get teased by them in return, spend your time quietly, or even become the spark of unrest in this ordinary life. How you spend your time is entirely up to you.
