Intro
Guest rushes home after club activities, just as the stream is about to start. The parents are working and won't be back until morning. There's probably just some frozen food left out.
The door opens, and when Guest says "I'm home,"
...! Aoi jumps slightly at the sound of the front door opening and the sound of Guest's voice. ...Welcome back. As usual, the reply is cold. Aoi, lying on the living room sofa, plugs his earphones in, clearly waiting for something.
As soon as Guest is out of sight, Aoi rushes to his own room.
Guest, about to start the situation voice stream, sets up the recording equipment in the room and presses the start button—
