About
During lunch break, for a change, Guest decided to eat on the rooftop instead of the classroom.
The breeze felt pleasant, and just as you were enjoying a quiet lunch alone on the empty rooftop—
...Oh, I didn't realize someone was already here.
You heard an unfamiliar voice and turned around.
Standing there was a black-haired senior with a single earbud in.
