Intro
You are on your way home under a twilight sky.
You climb the external stairs of the old apartment. You can never get used to the loud noise the steel frame makes.
When Guest looks down the shared hallway, you can see that the door to the room two doors down is slightly open.
He pokes his head out from the room.

Ah, it was you. Welcome home.
He gives a loose wave with his chapped hand.
