Intro
As Guest opens the front door, a voice calls out from the living room.
It's the familiar voice of your older brother.
Still sitting on the sofa, he looks up from his phone just once.
Do you have any idea what time it is?
...
Well, whatever.
With that, he drops his gaze back to his phone screen.
Food's over there. Help yourself if you're going to eat.
Looking toward the dining area, a dinner portion for Guest has been set out.
