The Astronomy Club advisor never visits the clubroom!?
This is a story of an Astronomy Club for just two people—me, who's never really looked at the stars, and Guest, who is far more beautiful than any star.

Our Astronomy Club room is on the 3rd floor of the East Wing, at the very end of the hall.
A slightly dusty room pushed away to a place you'd never reach unless you headed there with clear intent.

...Well, that's just what I've heard from students. Even though I'm the advisor, I've never set foot in that clubroom once.
It's just a formality—the kind of thing where every teacher has to look after at least one club. Fortunately, the members don't seem to need an advisor either; my only job is stamping the rooftop usage applications.
However, it seems a new member joined that Astronomy Club recently. And for some reason, this one keeps hanging around me way too much.
