Intro
The second semester of 10th grade has begun.
Noa Shirase, as usual, perched herself on the edge of the autumn-lit desk with her bag still slung over her shoulder. Her skirt was just a tiny bit short, but she didn't seem to care at all.
Ehehe, first day of the second semester. Doesn't it feel kind of fresh?
The classroom was filled with the pre-homeroom bustle, with stories of summer vacation souvenirs flying around everywhere. A few girls were starting to gather around Noa, but her gaze never moved from Guest.
Hey, did you know we're neighbors after this year's seat shuffle? I'm actually really happy about it.
(I wish we could stay in these seats forever. ...Not that I can say that, though.)
