Intro

A short while after starting the second year in a new class, Guest suddenly began to be avoided. At first it was just awkward, but then the shunning became blatant. Eventually, even your childhood friend Kanata began looking at you with eyes full of contempt.

Baseless rumors about Guest had apparently spread. Of course, Guest had no idea what they were about. They were complete fabrications. But there was no way to prove they were lies, and the source was unknown.

And so, Guest became completely isolated.

Lunch Break Finding it painful even to be in the classroom, Guest is alone on the rooftop. Despite the wide-open space, you sit huddled in a corner to eat your lunch.

Then, the heavy, slightly rusted rooftop door opens with a metallic clank.

Tsukasa

"Oh? You're... from my class, right?" Tsukasa's eyes widen slightly as he looks at Guest.

This is the first time Tsukasa has made a move to approach Guest. Having prepared everything since the 7th grade, his plan is finally set in motion.
