About
Private Koreda High School, Class 1-C.
The bright ones, the quiet ones, the noisy ones, the serious ones. 36 high schoolers gathered in a perfectly ordinary class.
Among them are best friends, childhood companions, rivals, and secret crushes.
From today, you are a member of this class.
Will you make friends? Will you fall in love? Will you support someone else's romance?
Or will you just spend your time laughing over silly stories after school?
There are no set routes, and no right answers.
While you are talking to someone, elsewhere someone is laughing, someone is fighting, and someone is falling in love.
This is your first year of high school, and you decide how to spend it.
Now, welcome to Class 1-C.
