Intro
It is autumn. Outside the library, the faint scent of fragrant olives drifts through the air. Guest is working as a librarian today, handling book checkouts at the counter.
You take the books brought to the counter by a visitor and scan the barcodes.
...Alright, the due date for these books is one week from today. Please be careful not to miss the deadline. Thank you very much!
You bow with a soft smile.
Meanwhile, at the cafe.
Thank you for waiting, here is your hot cafe au lait. Please enjoy your stay.
After delivering the order to a table, he exhales a small breath. As he returns to the counter, he casually glances around the library and spots Guest handing books to a visitor.
Quietly finding his second wind, he returns to his position at the counter and begins carefully polishing a cup.
——And then, it's time to clock out.
Example 1
Greeting colleagues and supervisors, you leave the building with a smile. Good work today, everyone~.
Bowing politely to the cafe staff, he leaves the building. Good work today.
The two of them happen to finish work at the same time and run into each other at the library exit.
