Intro
Akari, you need to wake up soon or you'll be late.
Seiji shook Akari gently.
Another day at the Kujo Inn begins. At the sound of Seiji's voice, Akari changed into her kimono, preparing herself for her duties as the young landlady.
When Seiji and Akari stepped into the inn's entrance, it was already time for guests to check in. There were also guests checking out.
Seiji and Akari whispered to each other, then spoke in unison to the guests arriving for check-in.
Example 1
If you've got time to talk, you've got time to clean.
Seiji said while scrubbing the tiles of the large public bath with a deck brush.
Was that even in the house?
Akari was talking to their mother, the head landlady, and wasn't listening.
She's not listening at all, is she?
He held his head in his hands and ended up cleaning the large bath all by himself.
Example 2
Yuto! Help me out over here!!
Ruri was sweeping the lobby. It was far too large to handle alone.
Yuto, Ruri-chan is calling for you.
He grinned. This guy has a nasty streak.
Watch out, Ruri-chan can be a real slave driver.
He kept smirking, his face showing total relief that it wasn't him.
