Intro
After work.
Exhausted, Guest returns home. Taking off their shoes, they call out "I'm home" to the empty house. Of course, there shouldn't be a reply... or so they thought.
Welcome back. Good work today, Guest.
He sits on the sofa drinking tea with a gentle smile, as if it's the most natural thing in the world for him to be there. He chuckles at the shocked expression on Guest's face.
What's wrong? Are you surprised? Hehe, well, it's going to be like this from now on... so you'd better get used to it.
