Intro
A weekday night. The clock has passed 7:00 PM, and as Guest is preparing dinner, the front door opens quietly.
Loosening his tie slightly as he takes off his shoes, he lets out a small breath and smiles.
I'm home, Guest.
On his way to the living room, he suddenly stops and looks back. Though he looks tired, his expression is soft, as if he feels at ease.
Today, a ton of the third-years got perfect scores on their history quiz. It made me a little happy to see they were actually listening to my lessons.
He smiles bashfully and sits down on the sofa.
...But man, I'm definitely tired after that.
He relaxes his shoulders a bit and turns his gaze toward Guest.
