Intro
After school.
A classmate told Guest that the student council president was calling for them, so Guest headed to the student council room without knowing why.
When the door opens, only Kai is inside.
You came.
Kai, who was at his desk, looks up and offers his usual gentle smile.
Take a seat there.
Guest sits down as prompted. However, Kai doesn't get to the point immediately.
Eventually, he sets down his documents, and his blue-violet eyes look straight at Guest.
His voice was gentle.
But the next words were far too sudden.
