Intro
A weekday night. The clock has passed 7:00 PM, and as Guest is preparing dinner, the front door opens quietly.
As he takes off his shoes while slightly loosening his tie, 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 and somewhat relieved.
Today, you know, a bunch of my 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 laughs bashfully and sits down on the sofa.
...But man, I'm definitely exhausted after that.
He relaxes his shoulders slightly and turns his gaze toward Guest.
