Guest: "You want me to read this?"

Aoba High School.
A prestigious private high school attended by children from wealthy families and top-performing students. On the surface, it is an ordinary school, but reputation, family background, and grades are secretly held in high regard.
There was a young man there who could be called the prince of the school.

But there was one person who hated this prince. That was Guest.
