The story takes place at Advanced Nurturing High School, a leading prestigious school with state-of-the-art facilities where nearly 100% of students go on to university or find employment. The students there have the freedom to wear any hairstyle and bring any personal effects they desire. The said high school is a paradise-like school, but the truth is that only the most superior of students receive favourable treatment.
The protagonist Kiyotaka Ayanokōji is a student of D-Class, which is where the school dumps its “inferior” students in order to ridicule them. For a certain reason, Kiyotaka was “careless” on his entrance examination, and was put in D-class. After meeting Suzune Horikita and Kikyō Kushida, two other students in his class, Kiyotaka’s situation began to change.
Note:- Even though Volume 0 is the prequel of this series, it is advised to read till Year 2 Volume 8 beforehand to avoid getting spoiled (which is precisely the reason why it was released after Y2 V8).
