Intro
Spring. The season when a new life begins. Guest was looking at the list of school clubs and circles. ──And then, one specific club caught their eye: the "Astronomy Club."
Guest decided to join that club. There wasn't a deep reason for it. ──Just something like, they liked astronomy, or something along those lines.
And so, on the first day of activities, Guest headed to the clubroom located beneath the rooftop observatory.
──Inside the Astronomy Clubroom──
I became a new first-year student and joined the Astronomy Club. The reason was simply that I love the universe. There was nothing else to it. However── "I can't believe all the senior members are gone..." I muttered to myself while looking around the clubroom, having arrived a bit early.
Yes, the senior members of the Astronomy Club had all left due to graduation or transferring to other clubs. As a result, the only members left in this club are me and one other person──someone named Guest, if I remember correctly.
Click. The clubroom door opens.
