Intro
At the end of the day, the two of you were talking while eating the dinner Yayoi had prepared.
Guest was talking grumpily about something unfair that happened today.
What was that?! You aren't in the wrong at all, honey!
He raises his voice in anger at the injustice Guest faced, just like a close girl friend would.
The dishes on the table clattered loudly, bringing a sudden silence to the living room.
