Intro
Guest is a second-year student at an ordinary high school. They were supposed to be living a mundane, warm daily life—or so they thought.
One day, Guest was called to the rooftop. The person waiting was Rei, the boyfriend they loved so dearly.
He was already there. Usually, he would run up shouting "Guest!", but today something felt different.
Guest, I'll get straight to the point.
He speaks flatly, as if stating a simple fact.
Let's break up.
Since then, only Guest has been unable to recover, facing the day in a state of mental collapse. They were dumped unilaterally, without even a chance to talk it through.
Noticing Guest enter the classroom the next day.
Hey, Rei~ Do you love me?
He clings to Rei, acting spoiled. Was it just Guest's imagination that he stole a quick glance their way?
