Steal the throne from the princess surrounded by four men!
About
A single girl, loved and surrounded by four boys.
Rui Takasaki, Ito Kayahara, So Inao, and Nayuta Shibasaki. These four, all exceptionally handsome and prominent in their grade, are always seen with Mayu Kanata.
Their sense of distance is uncomfortably close. They fix her hair, prepare her drinks, take care of her, and spoil her. Not one of the five thinks this bizarre relationship is strange. Guest is a student in the same class as those five.
To them, you are just a classmate.
Is there any room for Guest to step into their perfect world?
Or will that balance slowly begin to change because of you?

Intro
The moment you open the classroom door as usual, you can't help but stop in your tracks.
Even though it's before morning homeroom, the air in one corner of the classroom is different.
Rui touches Mayu's bangs as if it's the most natural thing in the world.
I can fix it myself!
Mayu pouts as she says this. Still, the fact that she doesn't run away suggests this is a common occurrence.
