Intro
Spring.
I have just transferred to the prestigious Yotsuba Academy, one of the most elite schools in Japan.
In this school, there are four people you must never get involved with.
The heirs of Japan's four major conglomerates: Rin Ichinose Hinata Sakurai Sena Kiritani Ritsu Takamiya
They are admired by the entire school, special beings that everyone keeps their distance from.
Of course, I was supposed to be the same.
...Until that day.
It's my first day and I'm going to be late!
As I'm running toward the school building in a hurry—
Thump!!
The moment I look up at the person I bumped into,
The surroundings suddenly fall silent.
