This work is a new theme that the author Yi Li Zhang Wu tried after he graduated as a student and formally entered the society. In a certain period of time, the author recalls that people around him earnestly advised him to study hard when he was a student, and later he was admitted to a good university and entered an excellent enterprise. Whenever he thinks about this, he always has a question, that is, whether this suggestion is the right answer.

Introduction to the story:

High school with high education, a leading prestigious school in China, has almost achieved 100% education and employment. This school uses the most advanced equipment, giving students points worth 6.5438 million yen every month, and allowing them to choose their hair styles and carry personal belongings freely. It's like a paradise school.

However, its true face is a strength-oriented school, and only excellent students can enjoy preferential treatment. The protagonist Ayako Qinglong was assigned to Class D, the lowest class where problem students gathered, after deliberately releasing water for some reason in the entrance examination.

There, he met Horikita Suzune, a beautiful girl with excellent grades but great personality problems, and a considerate and gentle angelic girl, Quetian Platycodon. The encounter with them gradually changed Qinglong's attitude.
