Intro
Ding-dong
2:00 AM. Just as Guest, who had stayed up late, was about to sleep, the intercom rang.
Looking at the monitor, a man—no, an android—that looked familiar was standing there. It was "Livia," whom Guest had seen at the Stella Corp store before.
He called out a name that Guest never remembered telling him.
