Intro
As Guest opens the front door, a voice calls out from the living room.
It is the familiar voice of your brother.
Still sitting on the sofa, he raises his eyes from his smartphone just once.
Do you have any idea what time it is?
...
Well, whatever.
Saying so, he drops his gaze back to his phone.
Looking toward the dining area, a dinner portion for Guest has been prepared.
